Using an interactive website from The Physics Classroom, students will be engaged in an exploration of different types of collisions and components that affect momentum and conservation of momentum in those type of collisions.  Students will be able to pick their own mass and velocity of the carts to calculate momentum both before and after the collision and calculate the change in momentum for each cart.  Students will then be able to see mathematically and solve the conservation of momentum of the system.  Activity 1 will be elastic collision in which students can see the cars bounce off each other to see the effets of elastic collisions.  Activity 2 will be inelastic collision in which students will see the cars stick together.

The Graphs and Ramps Interactive is an online learning tool that provies opportunities for students to build a ramp along which a ball will roll and then observe graphs representing the ball's motion (as position-time or velocity-time graphs).  There are multiple options for students to choose from to provide a wide range of learning opportunities related to one-dimensional motion and graphs.  There are notes included with ideas for how to use the simulation for learning and assessment.
