In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping. Learners can even slow time and transport the lab to different planets! A chart shows the kinetic, potential, and thermal energy for each spring. Use this activity for a lesson on Hooke's Law and Conservation of Energy. This activity includes an online simulation, sample learning goals, a teacher's guide, and translations in over 30 languages.
