matter is everything around us that has weight or mass. there is 5 states of matter first one is gas second one is solid another is liquid another is plasma witch the universe is made up of 99% of it and earth only has a little bit of plasma and the last one is Bose–Einstein condensates witch is close to absolute 0 and was man made i 1995 . all of the 5 states are made up of atoms. the atoms inside of solids are tightly packed. atoms inside of liquid are further apart. atoms inside gas are far apart. atoms inside plasma go crazy. Bose-Einstein condensates just has one big atom. your weight o the moon will always be less then your weight on earth. matter can be seen and felt and all mater has volume.
this is a atom
this is the Bose–Einstein condensates being made this is the 4 stats and the 5 one inst here
this Bose–Einstein condensates is what it looks like in space
lesson 2 year 6 science
we learnt about physical and chemical changes and we did an experiment with paper when you screw it up and rip it its a physical change but when you light it on fire and it smells and it turns to ash that a chemical change because something has formed from something . a physical change is when nothing is formed but it might feel or look different. we also talked about safety precautions when we do experiments like be careful with the test tubes and do not touch the dry ice when we use it because it is -78 cellist witch is cold and can give you frost bite. we also talked about the right way to mix things like the flicking technique and also how to measure with the thermometer and how to red the red line in the middle read with the numbers.
this is a chemical change this is a physical change
