Build It! In this activity you will build your own roller coaster out of materials from around the house. How does this change the speed of the marble? If there is not enough force will the marble make it through the entire roller coaster.

Draw It! Draw a picture of your own roller coaster. Be sure to include many twists and turns. Make it colorful and be creative. Remember each time that there is a change in direction or speed there is a force that is being used.

Build It! You will be able to see how forces affect how a boat floats. You will get to build your own boat out of foil and count how many pennies the boat can hold before it sinks.
