Kitchen+Chemistry

For the last 4 weeks of Term 1 we have been learning about Kitchen Chemistry.

We started by looking at **Melting**. We predicted what would happen to a marshmallow squashed between chocolate biscuits and put into the microwave. We had melted chocolate and marshmallows everywhere!! We also did an experiment where we tried to melt ice as quickly as we could and tried to stop the ice from melting. We soon dicovered that ice needed heat and warmth to melt quickly. We tried different ways to stop the ice from melting like covering it with a towel and putting it back into the ice cube containers but it didn't quite work.

Next we looked at **Dissolving**. We now know that dissolve means to vanish when stirred into a liquid and that's what happens to JELLY. We love eating jelly! We did an experiment to see if icing sugar, sugar, sand and weektbix dissolve when mixed with water. The sugar and icing sugar did but the sand and weetbix didn't. At breakfast the next day some of us tried to see if sugar that dissolves dissolves on top of a weetbix that doesn't dissolve.

After that we looked at **Fizzing and Foaming**. We had a lot of fun making a volano. We learnt that a chemical reaction of fizzing occurrs when you mix baking soda with vinegar. We also made Sherbet. It was yummy, sour, fizzy stuff! We liked that we could take some home to share with our family.

Finally we tried **Floating and Sinking**. We predicted whether lots of different kitchen/household items would float or sink. Most of us predicted correctly. We found out that floating is when something stays on the top of the water and sinking is when something goes down to the bottom of the water.

It was fun doing Kitchen Chemistry - come and check out our Kitchen Chemistry book in class.
