We are learning about science experiments. I enjoyed doing them and I found it challenging to explain what happened.
Mix it up
Why do some ingredients seem to disappear when you mix them together? Why don’t others? A mixture is two substances that don't chemically combine and can be separated. If you put iron filings into sand and raro, you can remove the filing with a magnet. Then you can remove sand out of raro when you put water with the sand and raro. The raro will dissolve. Then get a filter paper and pour the mixture into the filter paper. The sand will stay inside of the filter paper. Next leave the raro in the sun and you will have raro crystals because the water evaporates.
