On Wednesday we embarked on a scientific journey with toy cars made out of recycled materials such as cardboard, plastic bottles with their lids and some pieces of a used hose. We added the kebab sticks, drinking straws, buttons and balloons and voilà! Well, almost. Some cars worked well, while the others did not. Therefore now, we have the opportunity to use a scientific method where we pose a question, next formulate hypothesis, then experiment and note down the results and finally draw a conclusion. Learning is truly fascinating!
