Elephant toothpaste experiment booklet for Year 2 to Year 5 (KS1-KS2, Grades 2-5): printable science worksheets that guide children through a safe, foamy chemical reaction from prediction to conclusion.

Pupils learn what elephant toothpaste is (not real toothpaste, just a fun chemical reaction that makes a huge foam), follow safety rules, check the materials, measure and mix the ingredients, make a prediction, follow the steps in order and then record observations and results. Reflection pages ask what happened, why it happened and how the experiment could be improved.
