In session one we defined velocity and acceleration calculated velocity and acceleration and explain the relationship between acceleration and gravity. In session 2 we defined the relationships among frequency, pitch, amplitude, and loudness. Experimented sound waves and listed the steps necessary for you to hear sound. In session 3 we defined hypothesis. Made a hypothesis about expansion of materiel when its heated and tested it. In session 4 we listed the steps of the scientific method. Them we learned the difference between insulator and conductor. Then we conducted an experiment to measure materials ability to conduct or insulate heat.
