The grade 9 science class has been busy so far this octomester! In our first unit we learned about the steps of the scientific method and how we actually use these steps to conduct scientific experiments in our daily lives (i.e. Why isn’t my toaster working?). We practiced designing experiments, making sure that only one variable was changed so that it would be a fair test.
For our chemistry unit we learned about physical and chemical properties. We examined different foods in our kitchen, using our senses to describe them and completed density and viscosity tests. Students also conducted their own solubility experiments. When discussing chemical properties we explained reactivity with the classic vinegar and baking soda demo and tested the acidity of various household products using red cabbage as a pH indicator.
To bring these units together, students had to design an experiment to test products at home. They came up with a testable question, described the properties of the products involved, went through all of the steps of the scientific method and shared their results with the class. We had a wide range of questions, including “Which glue dries faster?”, “Which chip is the spiciest?”, and “Which car will go farther?”.
Students enjoyed completing their experiments at home, but are happy to now be back in school every other day where we can do more engaging activities together (but still 6ft apart!).
