Fourth Grade, Space Exploration Science Projects (4 results)

Space exploration is an exciting and wide-ranging area. Getting into space (and back down) is hard, involving rockets and launch vehicles, satellites, spacecraft, re-entry systems, landers and rovers, robots, and orbital mechanics, not to mention hypothetical technologies like space elevators and artificial gravity. To survive and thrive in space, we must understand many additional issues such as human performance in space, the space economy, and the science of astronomical bodies.

Science Fair Project Idea
How does a parachute work? Do bigger parachutes work better than smaller parachutes? Find out in this science project if the size of the parachute matters. Read more
Science Fair Project Idea
The idea of a colony on Mars is exciting! In this science project, you will tackle one of the challenges a Martian colony will face: what will buildings on Mars be made of? In this project, you will make bricks from Martian-like ground cover and measure how strong these bricks are. Read more
Science Fair Project Idea
3... 2... 1... 0— blastoff! In this science project, you will use a bottle rocket launcher to launch your own bottle rocket. You will load it with water and pressurized air, make several launches, and find out what makes your rocket soar the highest. Read more
Science Fair Project Idea
To be able to live on Mars, humans need breathable air, clean water, and nutritious food. Spacesuits can provide oxygen to breathe, ice on Mars can be a source of water, but how could we get nutritious food? Today's astronauts bring food with them. But a manned trip to Mars would require food that was either successfully grown in space or on Mars, as taking the extra weight of food for such a long time—it takes 6–9 months one way—is just too costly. In this project, you will… Read more
