Teachers, save “Sailboat Regatta Challenge” to assign it to your class.

This activity aims to build a sailboat that will float the distance of the water track carrying gram pieces. You can use two pieces of aluminum foil, 20 popsicle sticks, ten straws, and hot glue. This activity is about forces and displacement. The force of gravity is pushing down on the boat. The force of buoyancy is pushing up on the ship. If your boat floats, the force of the wind from the fan will push your boat across the water. 1. Collect your materials. 2. Build your boat. 3. Add 20 grams to your boat. Put it in water. Does it float? If yes, take a picture and move to the next step. If not, improve your boat. 4. Turn the fan on to medium speed. Does your boat move from one end to the next? If yes, take a video on slide 1 and move to the next step, If no, improve your boat. 5. Add a total of 40 grams to your boat. Put it in water. Does it float? If yes, take a photo and move to the next step. If not, improve your boat. 6. Turn the fan on to medium speed. Does your boat move from one end to the next? If yes, take a video and move to the next step., If not, improve your boat. 7. Repeat by testing 60 grams (slide 3), 80 grams (slide 4), and 100 grams (slide 5). 8. Explain the science on slide 6. 9.
