More About Experiments
Long ago, people did small tests to learn. They would try things and write down what they saw. This helped them know more about the world.
Now, we use experiments in school and at home. We can learn about plants, rocks, and even how to mix colors!
In the future, kids will keep doing fun tests. They will find out more cool things about life and how stuff works!
