Science Week

In class today we carried out a simple experiment. We made lemon suds.

For the experiment you will need:

a lemon

baking soda

a cup

a teaspoon

1. Put a teaspoon of baking soda into a cup.

2 Squirt  some lemon juice into the cup.

Result

The mixture makes fizzy bubbles and lemon suds.

A gas called carbon dioxide is trapped in the bubbles.

lemon is an acid and baking soda is a base. when the two are mixed together they form a gas called carbon dioxide.
