Science Experiments for 7 to 11 Year Olds (KS2)
- Thermal Powered Flower
(Ages 9-16)
Have you ever seen hot air rise? In this project, explore the physics behind thermal air currents (hot air rising) by harnessing them to power your own spinning flower! Note that this project uses fire and paper, and should only be attempted with adult supervision. Happy spinning!
Egg Drop Project(Ages 9-16)
When an egg drops from a second-story window, it picks up 32 feet/second of speed for every second it falls. By the time the egg reaches the ground, it’s going at about 24 miles per hour. And then, suddenly, its speed drops to 0 miles per hour (usually along with a big SPLAT). How can you get an egg to drop without breaking it? Change the way it drops with this awesome egg drop experiment!
Corrugated Cardboard Challenge(Ages 9-16)
Corrugated cardboard is a great and sturdy building material. What’s even better is that it’s super easy to come by–just check your recycling bins! So, here’s your challenge:
Make a stool or a chair using corrugated cardboard!
Parachute Toy(Ages 9-16)
In this experiment, kids create a parachute toy using a sandwich bag to learn about air resistance and see it in action!
Graphite Circuit(Ages 9-16)
Can you complete an LED circuit using a graphite pencil? Learn about the conductive properties of graphite and draw your own design to see it light up! This is a super quick and easy science experiment that is entertaining for both kids in KS2 and adults alike.
Explore the Periodic Table of Elements through a fun game! Just print out a couple Periodic Tables, follow the instructions in this awesome article, and brush up on your chemistry!
Challenge your kids to build their own version of this rubber band race car and then let them spend an afternoon hosting their own races!
Create your very own balloon powered rockets and see how far they can travel. Experiment with different balloon shapes and sizes to experiment with the travel speed. You can even add some cargo for your balloon rocket, and see how that impacts the journey!
Water is usually loaded with particles and impurities, which enables ice to form. But purified water isn’t. This allows purified water to reach way colder temperature before solidifying.
If you leave an unopened bottle of purified water in the freezer for two to three hours, the bottle will be way colder than the freezing point of regular water. When you pour that super-chilled water onto a block of ice, it latches onto the ice’s impurities and freezes instantly!
Pumping Heart(Ages 9-16)
Curious about how your heart pumps blood? Create a model to learn about the right atrium and the ventricle!
Plant Light Maze(Ages 9-16)
Have you ever noticed how plants grow toward the light? Build this simple light maze, and watch the plant grow around the obstacles to reach the light! Try experimenting with different mazes and see how the plant reacts. Can your plant complete its maze?
