St. Patrick's Primary, New Stevenston

P4 Science

| 0 comments

Primary 4 carried out a science investigation using 2 slices of apple and a 2 tomatoes. We wanted to discover what would happen if we mummified fruit.

We mixed the salt and baking soda together, this was our natron. Natron draws water out of things and dries them up. This is why salty things make us thirsty.

By drying something out, it doesn’t have the moisture it needs for the rotting process, so it works as a preservative.

We are excited to observe the changes that will take place and see if our predictions were correct.

Well done Primary 4. 🙂
