Kitchen Science

Over the next 3 weeks the Year 4 classes are conducting a variety of Science Experiments for our School Wide Inquiry Unit 'Kaboom!' Our focus is on Kitchen Science and the children will spend two lessons with each teacher.

Last week in Room 22 we looked at Liquids, Solids and Gases and we made delicious vanilla ice cream. It was a simple and quick experiment that many of the class are keen to try again and at home - and this time make a much larger amount!

Making Ice Cream

Aim - to make a liquid change to a solid

Method -

Equipment - ice, salt, blue milk, sugar, vanilla essence, small and large ziplock plastic bags

Process - 1: Put 2 cups of ice and 2 Tablespoons of salt into the large plastic bag

2: Put 100ml of BLUE milk, 2 Tablespoons of sugar and 3-4 drops of vanilla essence

into the small plastic bag. Ensure it is securely closed.

3: Put the small plastic bag inside the large plastic bag and shake for 5- 10 minutes

4: Feel the small bag and when it has changed to a solid state remove the bag and

rinse it under the tap. Open the bag and serve your ice cream.

Results

We learnt that the salt dissolved into the ice, drawing heat away from the milk mixture causing it to freeze more quickly. The liquid milk was changed into a solid. However when we put the ice cream into our warm mouths it became a liquid again!

The 'Ice Makers' collect the ice and salt

The 'Dairy Farmers' gather up the ingredients for ice cream making

Georgie makes sure the bag is tightly sealed. We didn't want any salt in our sweet ice cream!

Tasting Time - Yummy!

Isabella would like a second helping please

The 'Ice Cream Truck' collected the spoons and serving dishes and served the ice cream to all their group members.
