# Electricity

Week 1

Here is a photo of my energy project…

Here is a photo my circuit project…

Week 2

This week we actually got to make the circuits, I took me a while but I finally got the hang of it. It is the same circuit as the last picture for week 1. Except with the real thing. here are a couple of videos and photos of it…

# Spheros

On Thursday and Friday on week 4 we did something new. This was new, but it wasn’t, it was a robot, that was round, it was a Sphero. We got into pairs to experiment, we played around for a bit but then things started to get serious, we had to make the robot go around a 2D shape it was hard, but it wasn’t for I can program, but I have never done it on a Sphero before using blocks, I had done it using the drawing mode though, which is where you draw something and it does it on the Sphero. Anyway, the blocks, you can use many blocks on Sphero I learnt some are even like the ones on the other robots. I tried this program first but it didn’t seem to work…

The reason this didn’t work was because it was facing the same way the whole time so then I tried this…

For this one I started at zero and added 90 each time because I was doing a square and 360 divided by 4 equals 90, 4 because a square has 4 sides and 360 because if you measure the outside of a square it should always equal 360. I ran out of time to test it, but I will next time we do Spheros.

Week 9

The first challenge of the day was to make the sphero go around a shape here is my group’s shape…

We started off my testing all the sides of the shape, so we cold tell how far to make the sphero go. it took heaps and heaps of tries but finally we got there (it took so long because of the sides!). Here is the video…

My Movie-2827qlg

Next challenge was to create a maze to go around, ours looked something like this…

We decided to do it bit by bit. It took a long time to do, but we still hadn’t finished getting around yet. some problems were…

• The blocks in the way
• The spheros aim (were it is pointing)

But we overcame them all in the end here are some videos of the session…

# Term 3 Robotics

Black line challenge:

Today we started a new task but from being away, it was going to be difficult, all the robots looked like they had a costume on with all of the new sensors. Luckily for me we were starting on a new sensor, the colour sensor. Our task was to make it follow the black line, my group managed to make it go straight, but that is about it, this didn’t work because the challenge was to make it FOLLOW the black line not program it to go straight. Then when we all thought it was never going to be possible, there it was the program gleaming up on the board…

So how it works is, the button at the start is, well the start button, it makes the program start. Next is the comment block, I find one of the most useful blocks, it helps you to tell the robot what to do if there is not a block for it. Then the loop brick, it tells the program inside of it to keep going if you look to the right on the loop brick you will notice an infinity symbol that is set to infinity so it tells it to go on forever, but there are other settings to. In side that is a switch brick, it is set to colour sensor and to the colour black, so that it will follow the black line. You may notice the tick and the cross, they both have inside them the motor on, but the comment brick one of them says, “If the robot sees black turn right.” The other reads, “If the robot does not see black turn left.” Now if the robot sees black it will go onto another colour and if it does not see black it will turn left until it sees black again. The tick is there because it says, “sees black” whereas the cross says, “does not see black”. That is it; here are some videos of the program working…

This one is of the robot just going straight…

WIN_20170725_15_10_49_Pro-q6suku

This one is of it going around a black circle using the program we talked about before…

robotics 1-2iqeysi

At the end of the week, we printed out our programs and wrote in what it all meant.

What I learnt was that there was a comment brick and I find it very useful to use.

What’s next? Next will be a surprise for me as we will be moving onto another challenge probably next time.

Week 4

This week we were moving on, slightly, this time we had to use the colour AND touch sensor. I knew it was going to be tough for I had not used this touch sensor thingy before, so I did what the teachers ALWAYS told us to do if we needed help, ask our fellow pupils, and soon enough I understood the touch sensor. But it was still going to  hard. now et me explain what the robot had to do, it had to follow the black line using the colour sensor, and then at the end of the line using the touch sensor if something was in the robots way it would stop. I tried SOOOO many things including this program here…

I do not think this program worked because I do not really know how to use the yellow bricks.

Then when I thought all was impossible, help came, and I finished…

WIN_20170809_14_43_59_Pro-117djw4

That is all I got done for Monday-Wednesday because we also had to draw it in our books.

What’s Next? Next I will try to do it on a curvy line.

See what we did with Spheros on my “Spheros” blogpost.

Week 9

In robotics this week, we had six challenges to complete. I had already finished the first three, so I was onto the squiggly line. I thought it would be easy at first, I thought… I can use the same program that I used for the black line oval. However, it was not that easy. I tried so many programs, they all worked at the start, and it was just at the end that the spun off the course. I kept on trying though until in finally thought about a certain brick. Was it doing the right job?

This brick was a problem. However, I did fix it in the end. If you have ever used EV3s before I am sure that, you will know that the motors and sensors all have to be in the input. There was my problem. Turns out that the colour sensor was in input three instead of four.

Here is the end video program…

However, there was no stopping there, I had to make the robot go along a black line using the colour sensor, then using the touch sensor stop, turn around and come back to the start. The start bit was east as I had already done the first bit, so it was just a matter of turning around and coming back to the start. The problem was, the turning around, it just would not turn around properly. Once again, it was a simple problem, it was turning to fast. Frustratingly it took me about 12 programs to figure this out so I did not have much time left.

Any who here is the last program and video…

I was onto the 5th challenge, the black oval that should stop then turn around and go back to the start using both the colour and touch sensors. I thought, what if I used rotations, then I could count the rotations and then after it touch’s a hand it will turn around and do the same amount of rotations back to the start. I got a program but sadly did not get enough time to test it. Here is the program though…

# Scratch

Session 1: 25.7.2017

This past week we have been introduced and working on an AWESOME new program called Scratch.

I have learnt so much from these tutorials…

Here is a video explaining some of the new things I explored this week…

Scratch blog1-2jnlly3

Session 2

This week in scratch we made our own account which was very helpful and easy. It will help now because the app version does not have all of the right bricks.

Here is a movie of our challenges and tasks for this week…

Week 5 and 6

My Movie2-2dsrmog

You are probably wondering what the other lesson was for, it is for a new project called “Animations”, where you have to make other sprites move as if they were animated I used a dinosaur and a birthday cake, then we had to draw the changes in our books that took about the whole session, but I think I will work on this project at home. I will not me blogging for a while now as I am doing sewing this week and the week after is camp and then I will have to go back to robotics because I will have missed out on it in sewing, so…

See you in WEEK 10!

Week 10

This week is our last week of school. So we had to finish the scratch projects we were set by the end of the week. The first activity was the Debug it, I worked through all of the next ones and then decided to explain this one to you…

blog-1hj4eib

After we had finished that we had to do a challenge where, For reach character you made your own customized block. I will explain it to you now in a screencast…

my own blocks-1lu1s10

Well anyway, that’s it! See you next term!!

# MicroWorlds

Session 1: 18.5.2017

Today we did microworlds in maths. I created lots of shapes and learnt so much. It was half of one thing and half of the other today. The first half we used humans as a turtle and told  commands for it to do, it took a while but in the end we got there. The second half we were testing and creating programs. Here is a video of me explaining what I made and did…

Microworlds-1j5iwwb

I loved today, and can’t wait to get further into the project!!

Session 2:

Today in microworlds we had to write our initials with the turtle, but this was hard because some people had letters like b or c…

microworlds 5-t1ln1e

I cant wait for next session to start on my c!!

# Kites

Friday 13th May

Today in maths we were focusing on kites, first we had to try and make a kite by ourselves (I was not successful), but in the end Mr Mckie gave us the instructions once we had made two we did this…

Here are some other ways to prove out theory…

# Rube Goldberg Activity’s

This week we are doing another warmup for rube Goldberg we will go around to each of the teachers and learn about a simple machine.

1.5.2017: Mr Mckie

Today we were with Mr Mckie doing pulleys; we each got a sheet and had to get into pairs I was with Ella I think we worked quite well together. First, we read the sheet and then we got to work…

There were three different types of pulleys, the single, the double and the quadruple. Even though they all have different names, they have one thing in common this…

WIN_20170501_10_29_25_Pro-1965eom

This one worked very well going up and down. Then we did the double, this one was a little bit harder than the single…

This one was not as reliable, but still worked sometimes I do not think it worked very well because the string kept getting stuck in between the two cogs. Then it was time for the quadruple one; this one was going to be a tough one. It did not work for us, but we tried…

I am pretty sure this one didn’t work because there was lots of cogs which means lots of places for string to get stuck in.

In the end the single probably worked best for us because it was so reliable, I think this is because it is simple and not too many cogs!

2.5.2017: Mrs Watson

Today it was Mrs Watson with chain reactions, how exciting. Once again, I found myself picking a partner I chose Poppy; I think we worked well together as well. If you don’t know what a chain reaction is, it is something happening which causes other things to happen we were doing ours with Lego. Each partner got there computer, one for photos, one for the instructions (they were on our computers). So we got to work, finding and building when the lesson was over we hadn’t finished but I am looking forward to doing it in my spare time. Here are some photos of our progress…

3.5.2017: Mr Colbert

This session we were doing knexs, what?! I thought, how are knexs simple machines? But we got to work anyway, I was in a group with Lili, Josh and Oliver. We each got an instruction book with lots of different machines in it, we decided to do the carousel because it looked really fun and creative. We got to work but unfortunately didn’t finish but it looked pretty cool so far anyway. Oh and i almost forgot, you can make simple machines out of knexs for our carousel it was the bottom part, this part…

Here is a time lapse video of us building our carousel…

Carousel-24e220i

There is a simple machine in our carousel, the bit we built today, the wheel and axle.

6.5.2017: Joining

Today we were joining all of our simple machines together but first we had to finish our carousel, this is what it looked like in the end…

When we finished we had to get into a group, there weren’t many people left but we managed to find some people, I was in a group with Poppy, Lili and Hannah, I think we worked really well together. It was really hard to join all of our simple machines together, there were lots of little problems along the way but in the end we managed to overcome them all. Here is a video on our machine working and explaining how it works…

WIN_20170502_13_20_23_Pro-1eebj8t

I have learnt so much about simple machines during this period of time, and can’t wait to start the project later on!

# Lego Robotics

Session 1: Pseudocode and Robot build

Today was absolutely prodigious. Because we started our unit of robotics, I was so excited. At the start we got into our groups I had a group of two boys, Alec and Leo. We had to build a robot so we all set off to work, building and finding pieces, it was so much fun, but difficult too because when we were trying to find the pieces they were really hard to find because some were really small and some blended in with the carpet.  When we had to pack up I was pretty happy with our work we had gotten a lot done in the past two hours. Today I learnt how the actual robot looks, I was actually not sure what it was going to look like until today, and I think they look and act pretty cool.

Session 2

Today we were finishing off our robots again, for those who had finished though we had to draw a side of our robot, (like, side, birds eye, or front) then we would have to label the parts and explain what they do. This was over two session so I got three views done.  Each group had to find a part that they thought no other group would notice and trust me you probably wouldn’t find ours…

Session 3

Today I was so excited, we were going to start programming! First we started by talking about how to program, then we got to investigate, I made my robot show a picture, move and make a noise. After that we looked at other peoples programs, then they set us a task with one tile, we had to work out how to make a robot move using three different settings on the same tile, rotation, degrees and seconds I got all of them finished so next time I can test them out!

Here is the rotation…

Here is the degrees…

Here is the seconds…

I cannot wait to test them out next session!

Session 4: 23.5.2017

Today I tested them out and they all worked!!

Rotation…

rotation-yo3r43

Seconds…

seconds-21dzn19

Degrees…

degrees-1e5l3q2

But actually they all did work but after I changed the seconds one it finally worked I changed my seconds because

a) it was going to fast and

b) it was going for too many seconds.

So I changed the speed to 31 and the seconds to 5.

Here is my new program…

Session 4: 26.5.2017

Today we had three sessions of design, so I got a lot done. I had already finished my degrees, seconds and rotation so there was a new task waiting for me to complete. The challenge was to make our robot go around a square, it took a really long time because you had to measure how long each side was. I finally got it done though…

WIN_20170526_12_38_52_Pro-22rymq6

Here is a snip of a part of my program…

This continues another 2 times and then does the first tile again so that it makes a square.

After I had finished that I had to try and come up with another way to try and do it, I decided to use degrees, I got my program finished but I didn’t get to test it so next time I will test it out, here is a snip of this program…

This pattern again continues another 2 times and finishes with the first tile.

I cant wait for next session so that I can test my program out.

# Rube Goldberg machines

21.4.2017  Practise (hopefully) makes perfect.

Today when we came in to class after recess I was tingly all over with excitement. Because we were about to start our Rube Goldberg project except well this was going to be a practise. Now your probably thinking Abby hold up what is a Rube Goldberg machine? Well a rube Goldberg machine is basically a machine with lots of simple machines in it and they all add up together to make one complicated machine. But this machine is meant to do something that is so easy you don’t even think about it when you do it like, turning the page of a book or eating your breakfast. Ours also had to include at least three simple machines ours were, a pulley, a lever and a ramp. When I got to my group I was really happy because we all had so many great ideas so we tested out lots of them but finally came to the perfect design here it is…

rube Goldberg movie-2nkhf82

So we all went of searching for this and that it took forever but it was worth it because I found that if we all worked together it would be much quicker and we did. Here are some of our simple machines…

After we finished building and putting together the simple machines we put on a few finishing touches and tested it out (quite a few times)…

WIN_20170421_12_27_25_Pro-vt02at

WIN_20170421_12_41_57_Pro-1vic70n

WIN_20170421_12_43_44_Pro-1x49qnd

After this experience I have realised how difficult this project is going to be. But I cant wait to give it my best shot, and hopefully practise makes perfect!

Rube Goldberg session 2: 15.5.2017-16.5.2017

Today is was the real thing, I got into my group and we started designing, the first day we thought up our design, the second day we started drawing it, her is our design it is supposed to take a photo on a computer and but rubbish in the bin…

This is how it works…

The marble will fall into the funnel once the string is pulled by a person, once the marble comes out of the funnel in will roll down an inclined plane (made out of a pool noodle) and will hit some Lego dominoes (Lego because it is heavier). Once the dominoes fall down, they will hit a golf ball, which will fall into one cup on a pulley. The cup has a piece of Lego attached to it and has a computer sitting directly below it so when it goes down it should hit a key on the keyboard causing the computer to take a photo. Because the cup that just hit the computer is heavier now than the other cup, the other cup will go up. But it was a piece of Lego attached to the side of it and a platform (made from paper) with a piece of rubbish sitting on top of it sitting directly above it, so when the cup goes up the piece of Lego will hit the platform, causing it to tilt. The rubbish will then roll down the now created inclined plane and fall into a bin.

Some problems that I think might occur are:

1. The Lego piece that should take a photo will miss
2. The Lego piece that should tilt the platform will miss
3. The dominoes will miss the golf ball
4. The rubbish will miss the bin

How I could fix these problems:

Problem 1. Use a bigger Lego piece or structure

Problem 2. Use a bigger Lego piece or structure

Problem 3. Use taller and heavier dominoes

Problem 4. Make it a smaller piece of rubbish or make the edges taller on the platform.

I can’t wait to start building and know it is going to be so much fun!

Session 3

Today we got to build!! It was so much fun. First my group started on the first simple machine, the lever. But after a while we moved on from it because we realized there  was harder stuff to do like after the lever there is a funnel an inclined plane and some dominoes. and if the marble missed the dominoes then the machine will not work it took nearly the whole lesson, but in the end we got there. It still isn’t positively reliable but we are working on it. The reason why we started with this bit is it is the hardest bit so if we get it finished next session we can finish the project!

Session 4

This week my group were trying to make the pulley work but after a while we decided it just wasn’t going to work so we got rid of it. But after that we realised that the ball couldn’t just fall onto a laptop because the laptop would break, so we changed the purpose to just a piece of rubbish falling into a bin. We changed our design after some time because we realised the machine just wasn’t going to work. Here is a photo of our new design and a close up of some other parts…

So first of all what will happen is, the marble on this platform will be sitting on top of it, but once the string is pulled the marble will fall down the now created inclined plane and will fall into another inclined plane made from a funnel and a pool noodle…

# Angles Investigation

20.4.2017

Today in maths we did an angles investigation. We played three different games on our computers about guessing how big or small the angle is by using a protractor, after we had worked out how large the angle was we would check our answers by pulling down a tab that was covering the answer. We also played another game where we had to cover up two answers and then move a stick around to change the size of the angles. We did this activity with a partner so one could guess the right side of the stick and the other partner could guess the left side. then to check the answers we would pull down the tabs that were covering the answers. Here are a few of my games…

What I liked about this activity was using the protractor to measure the angles because I had never used one before. What I learnt today was that to measure a reflex angle you have to measure the smaller part of the of the circle and then subtract the number from 360 degrees and that is you answer.

21.4.2017

This maths session we were still doing angles. Except this time we had to draw a triangle on a piece of paper with a ruler, measure them with a protractor and label them whether they are a acute, obtuse or a right angle. the aim of this activity was to practise using a protractor. But we had to make sure we measured them properly or it wouldn’t add up to 180 degrees. It was very rare for me to get exactly 180 degrees because I was only new to using protractors but all of my answers were pretty close. Here is a photo of my work…

Now here is a photo of the one I felt easiest doing…

I felt it easy to do this one because it was my first one and I had made it quite easy for myself to do. But after a few I got to a hard one…

This one was probably the hardest because the angle are really small and hard to measure so I extended out the lines to make it easier for myself. I really liked this activity because some of the triangles were easy and some were hard. I learnt during this activity that small triangles are harder to measure because the angles are smaller, so it does matter about the size.

27.4.2017

this lesson we were still doing activity’s that used protractors. The first activity we cut a circle in half and then cut off the sides then we glued them all down and measured the parts, if you got 180 degrees then you had measured correctly, but if you didn’t then you didn’t measure correctly. Here is a photo of my work for this activity…

Unfortunately I got 182 degrees but that is pretty close so I was happy with that.
