At the elementary level, students in grades 2 and 4 were busy experimenting in their science class.
Second graders learned about the properties of different materials. Then they realized an experiment: they tested which surface would soak up water the fastest between cement, soil, and grass. Pouring an equal quantity of water on each element, they timed how long each material took to absorb the water and made notes.
Fourth graders learned about the pH of different liquids, testing vinegar, water, ammonia, and a baking soda/water solution. They discovered that ammonia and baking soda are basic solutions, meaning that their pH is higher than 7, while vinegar is acidic.
Elementary students are introduced to and learn the various steps of the scientific method: making observations, asking questions, testing the hypothesis and collecting data, examining the results and drawing conclusions, and reporting the results.
