Science Term3 Week 3.

In science we learnt how to find out if things had acid or arkali in them. We tested that by putting it in red cabbage water and it reacted depending if it had acid or alkali in it, if it had acid in it, it would go red, but if it had alkali it would go green. This is our work showing are research.
We found that in cleaning products they mainly had alkali in them and food materials had acid in them.
