Which Pizza will rise the most?

Shona and Susie's base groups have been learning and wondering about raising agents. We found out that raising agents make food rise. The four raising agents we have been talking about are eggs, yeast, baking powder and baking soda.

Today we experimented which pizza base would rise the most. We made two pizzas one with baking powder and one without.

Mitchell thought the pizza base with baking powder would rise the most.

Leola was curious to see which pizza rises the most.

In a big bowl we had:
- flour
- 1 tablespoon oil
- baking powder
- salt
- water

In the little bowl we had:
- flour
- salt
- 1 cup oil
- water

Then we had to put them both in the oven. We had to flatten it down with a rolling pin, a spoon or our hands.

We think the pizza needs to bake for around 30 minutes. We think it will be ready to eat when it looks stiff, a little burnt, golden brown, tan, maybe black around the edges, a little hard, crunchy or smooth.

We took a vote...24 people thought the pizza with baking powder would rise the most. 2 people thought the one with no baking powder would rise higher.
