Simple Machines In-School Field Trip on June 4th at 10 AM. This program focuses on forces, engineering, and mechanical science. We will divide the 40 students into age groups (K, 1st, 2nd, and 3rd) to tailor the experiments to each group's level. Each session lasts 30–45 minutes and includes a take-home component. The total cost for this visit is $600. We would like to offer you a $50 first-time discount, bringing the total to $550.
