10 Fun Science Experiments You Can Do in Your Back Yard

The backyard is ideal for many nature, ecology, and geology investigations, but it’s also ideal for physics, chemistry, biology, and astronomy research. If you’re intending to have anything splash, burst, or fly into the air, it’s much preferable to be outside where there are many fewer distractions than there are indoors to avoid home clutter.

Is It Going to Float or Sink?

This is an excellent outdoor science project for younger children to learn about the differences between floating and sinking objects, but older children will appreciate it as well. Begin by gathering objects such as rocks, leaves, twigs, and flowers from your backyard. 

Fill a bucket or container halfway with water, then guess whether each object will float or sink before putting it in the water to find out. Discuss how the distinctions between the things, such as weight and size, may affect the conclusion.

Rainbow Science Experiment

Academia, Tech, Engineering

On a hot day, this is one of the most entertaining science experiments you can conduct. Water and sunlight are all that are required. Simply fill a spray bottle with water and place it in a sunny position in the yard, or use your watering hose with the nozzle set to mist. See if you can detect a rainbow by spraying some water onto the sun.

Experiment with different angles and have your children explain why the rainbow vanishes when you move. It’s a fun approach to discuss how rainbows occur and, for younger children, to learn about the different colors. Just be prepared to get soaked.

Greenhouse Balloon

This is a hands-on science exercise that can help older children understand how greenhouses and ecosystems function.

Place the balloon on the funnel’s end and slowly pour the soil in. After that, carefully pour in the water and the seeds. Remove the balloon from the funnel, fill it with air to fill it up (but not fully), and tie it close.

Hang your balloon in a sunny window with some string tied to the knotted end. Check it every day for progress, and within a few weeks, you should notice some sprouts. Discuss how the closed balloon uses the sun to heat the air and create humidity, which then cycles back into the water for the plants as you examine the growth.

Mentos Geysers

One of the two liters of Soda bottles should be opened. Place it where bystanders won’t get splashed and the person putting the candy in will have enough room to flee. With one hand, hold the improvised dispenser and in the other, insert a thin piece of cardboard on the tube’s bottom. This prevents the Mentos from falling out before their time. Fill the tube with 10 Mentos. Place the cardboard and tube over the soda bottle’s opening. Remove the thin cardboard, like a magician sweeping off a tablecloth, so the candy can fall in.

Dirt Battery

What matters most is that your screws are galvanized steel. It contains nickel, which aids in its conductivity. They should be available at any hardware store. Each cell of the ice cube tray will require one.

Moisten the soil in your ice cube dish. If the tray is dry, wet it with a little liquid in each cell. If you add lemon juice or vinegar to the soil, it will become even more conductive. Leave the last screw without wire wrapped around it at the ends, and give the other one an extra piece of copper wire coming out of the last one.

In the end, if you used LED lights, the lights are simply placed in the dirt and will light up due to the charge created by the nails and wire.

Finding Out the Best Bubble Soap Solution

With just a few materials, you can make your soap bubble solution. With this fun outside science exercise, students may experiment to find the ideal proportion of ingredients to blow the longest-lasting bubbles.

Make and Fly a Kite

Begin by constructing a frame. Your DIY kite can be any size you choose. However, a larger kite will fly better than a smaller kite.

Two moderately long dowels are required for the diamond kite. One was 40 inches long, while the other was 32 inches long. Wrap some of your string tightly around the two dowels to hold the two pieces together. To ensure the correct shape for your kite, maintain them at right angles and the cross piece centered in the middle.

On a diamond-shaped kite, the tail may appear to be unneeded, but it serves a crucial role. A diamond kite’s tail helps to keep it stable in the air and prevents it from whirling wildly in the wind. Longer tails are more stable, but adding a small amount of weight to the kite using beads can help balance it without having to make the tail so long.

Bridle Construction The bridle is the method of attaching the string to the kite to keep it stable while flying. Tie both ends of the string to the horizontal dowel’s end.

Make a DIY Bird Feeder

Bird feeders are a fun DIY project that benefits both birds and people. There are many commercially available bird feeders, but making your own allows you to have complete design control.

Egg Drop Experiment

An Egg Drop Project requires you to drop an egg from a given height and see if you can build or make something to keep it from breaking. This usually entails creating a contraption to safeguard the raw egg. Parachutes, cushioning, popsicle sticks, and sometimes even bubble wrap are frequently used.

Catapult Experiment

The Catapult Cannon’s goal is to see how many projectiles can hit the target in one minute. You can either have each person create their catapult cannon using craft kits at your home or have them work in groups. Don’t be scared to give them the task of creating the design improvements that they believe would improve performance.
