The first challenge for the fourth graders will be to work with a systems model to demonstrate how energy is transferred from one object to another.

The second challenge for the fourth graders is:

Your task is to take the role of a large team of engineers. The team will be broken down into several smaller teams in order to create many products that will solve the challenge that we've been given.

Our overall challenge is to create a fleet of vehicles that will be powered by air to carry as heavy a payload as far as possible. Your team will need to overcome friction, mass, and gravity by creating enough thrust to move the vehicle forward. The design is up to your team, but you will need to use the given materials as your constraints. The best vehicle systems will be able to carry the load a long distance.

Develop a team name and report that to me as you work. Step one will be to meet with your team, develop a name, and discuss your plan. Good teams work well together, listen to each other, respect each other and share ideas. If a team has a great idea, should that idea be shared with other teams? Of course; this is collaboration, not competition!
