Astronauts orbiting the Moon in the Gateway spaceship will need to recycle water. You can make a water filtration system with a 2-liter bottle and other easy-to-find materials. Use your filter, then test your water to see how clean it is!

Heavy Lifting is part of the NASA STEM: Forward to the Moon Activity Guide. These hands-on science activities may be done at home with family, at summer camp or in a classroom. The activities supplement the STEM Education segment of the Apollo Anniversary broadcast first aired on NASA TV July 19, 2019. The guide uses STEM activities to share NASA’s plans to go forward to the Moon by 2024.
