3 Experiments and Nursery Rhymes

What an awesome afternoon we had with Room 2.  We completed three different experiments and worked on ordering some nursery rhymes as well.  We were pretty busy, but we had a lot of fun.

Our experiments were looking at Changing States of Matter. 

Lemon Juice & Baking Soda
What happens when we mix lemon juice (an acid) with baking soda (an alkali)?  We worked together to find out.  First we squeezed lemon juice into test tubes.  Then we tipped some baking soda in and watched what happened.  It was pretty exciting....

Baking Soda & Vinegar

What happens when we mix vinegar (an acid) and food colouring with baking soda (an alkali)?  We used eye droppers to pick up a mixture of vinegar and food colouring.  Then we dropped it into a tray of baking soda to see what would happen.  We had some magnifying glasses so we could see the action up close.  We listened to the sound it made too.

Working together

Oil & Water Art

If we mix oil, food colouring and water, does the oil dissolve in the water?  To find out what happens, we wrote our names in crayon on paper and then dipped our paper in a mixture of oil, water and food colouring.
