Boy, have we been busy little scientists! Variables aren't just used in math, we have learned. Students have used the science process skills of observing, inferring, and using the scientific method and variables to design their own experiments investigating potential and kinetic energy. They completed variable wheels to identify the variable they would manipulate, the responding variable, and the several controlled variables they would need to ensure valid results. They stated their hypotheses and after writing their own procedures, they performed their experiments, collected data, and concluded whether or not their hypotheses were proven or disproven. Ask your child how their teams experiment turned out. We learned a lot, not only about energy, but about the process of scientific investigations. This week we will practice creating data tables and then graphing the information. Students will learn which graphs---bar or line---are best suited for different types of data. Our next unit will be Mixtures and Solutions.
