About 3,000 years ago the people of Easter Island, a tiny little island in the Pacific, moved and built these really cool 14 ton statues called Moai Statues. This activity lets you be the boss of Easter Island. You direct the people so that they can be successful in moving these statues.

Design your own Rollercoaster -Make the most exciting rollercoaster ride that you can make without having the car go flying off of the track! You can do this by changing the height of the hills, the size of the loop, the starting speed of the coaster, its mass, the gravity at work, and the amount of friction on the track. Good Luck!!
