Worksheet Overview

Amy and Sam are doing a science experiment called 'Baking a Cake'! Sam loves chocolate cake so Amy has decided to use her method of baking to help Sam to understand some of the science behind cooking.

Brother and sister mixing a cake

"What do we need to make the cake?" Sam asks Amy.

"Oh, lots of things: bowls, spoons..."

"No, No!" interrupts Sam, "I mean what ingredients do we need?"

"Well, there's flour, sugar, eggs and milk for a start." Amy replied.

"What about chocolate?" Sam wanted to know.

"Yes, and that of course!" laughed Amy. "Anyway, let's get started."
