Homeschool Science Experiments

These science activities and projects will get your kids excited about learning science! If you're struggling to do science with your students, whether they attend public school, private school, homeschool or anything between, you are in the right place.

In this video, we're going to make a quick and easy drawing machine that will teach your kids about the conservation of energy!

Ep.23: Drawing Machine at Supercharged Science Cast

Hang Starch Ghosts from a slow-moving fan for a spooky and fun effect! It looks like they are simply floating around by themselves with nothing holding up their shape.

The Sun illuminates half of the Moon all the time. Imagine shining a flashlight on a beach ball. The half that faces the light is lit up. There’s no light on the far side, right? So for the Moon, which half is lit up depends on the rotation of the Moon. And which part of the illuminated side we can see depends on where we are when looking at the Moon. Sound complicated? This lab will straighten everything out so it makes sense.

Spectrometers are used in chemistry and astronomy to measure light. In astronomy, we can find out about distant stars without ever traveling to them, because we can split the incoming light from the stars into their colors (or energies) and “read” what they are made up of (what gases they are burning) and thus determine their what they are made of. In this experiment, you’ll make a simple cardboard spectrometer that will be able to detect all kinds of interesting things!

A meteoroid is a small rock that zooms around outer space. When the meteoroid zips into the Earth’s atmosphere, it’s now called a meteor or “shooting star”. If the rock doesn’t vaporize en route, it’s called a meteorite as soon as it whacks into the ground. The word meteor comes from the Greek word for “high in the air.”

This method uses the idea that an orbiting planet exerts a gravitational force on the Sun that yanks the Sun around in a tiny orbit. When this is viewed from a distance, the star appears to wobble. Not only that, this small orbit also affects the color of the light we receive from the star. This method requires that scientists make very precise measurements of its position in the sky.

This is REALLY easy to build. SUPER cool to watch (though most adults can’t figure out how it works until you tell them). And it teaches one of the MOST IMPORTANT concepts there is in science. Guaranteed to keep small kids and cats busy for hours :-)

You can install One Way Mirrors (most tinted windows can be converted into a one-way mirror) in your house by hanging one in a hallway and cover up the background with a thick blanket or sheet.

FREE experiment! Imagine a plate of spaghetti. The noodles slide around and don’t clump together, just like the long chains of molecules (called polymers) that make up slime. They slide around without getting tangled up. The pasta by itself (fresh from the boiling water) doesn’t hold together until you put the sauce on. Slime works the same way.

When trick-or-treaters answer your door, quickly turn off the inside lights, open the door, set off your Real Bats that Fly! Here’s how to make bats!

Let’s learn how to make loud sonic waves… by making an air horn. Your air horn is a loud example of how sound waves travel through the air.

Let’s take a look at whether hot air or cold air takes up more space. Here’s what you do:

If you can remember thermostats before they went ‘digital’, then you may know about bi-metallic strips – a piece of material made from of two strips of different metals which expand at different rates as they are heated (usually steel and copper). The result is that the flat strip bends one way if heated, and in the opposite direction if cooled.

This is one of those ‘chemistry magic show’ type of experiments to wow your friends and family. Here’s the scoop: you take a cup of clear liquid, add it to another cup of clear liquid, stir for ten seconds, and you’ll see a color change, a state change from liquid to solid, and you can pull a rubber-like bouncy ball right out of the cup.

    Make sure you wear gloves when doing this science experiment! If you're a science teacher in a classroom with lots of students, you can hand out plastic baggies to cover their hands.

We’re going to create the fourth state of matter in your microwave. Plasma is what happens when you add enough energy to a gas so that the electrons break free and start zinging around on their own.

Normally, when you decrease the temperature of water below 32 degrees Fahrenheit, it turns into ice. But if you do it gently and slowly enough, it will stay a liquid, albeit a really cold (supercooled) one!

Sparks flying off in all directions…that’s fun. In this advanced lab, we will show how easy it is to produce those shooting sparks. In a sparkler you buy at the store, the filings used are either iron or aluminum.

This is the kind of thing I wish I had back in grade school. I could have launched these across the room without anyone being the wiser.

This is the trick that magicians use onstage when they want to slip out of the rope handcuffs right in front of your eyes. Using a little geometry and logic, can you also learn how to wriggle free?

FREE NEW EXPERIMENT VIDEO!! I’ll show you and your kids how to turn a 99-cent laser pointer into an amazing precision measuring device that can accurately measure microscopic things, like the spacing between tracks on a CD, the size of bacteria, or the thickness of a human hair (or dog hair.. or whatever kind of animal you happen have around :)

This Tidal Disruption video shows what happens when a yellow star wanders too close to a black hole. This black hole is in the center of a distant galaxy. Notice how when the yellow star nears the black hole, the star gets stretched, squeezed, and then shredded and torn apart. youtu.be/zwNwfke9Uuk

    This science video was created by the folks at NASA using a computer simulator to show what would really happen near a black hole. This is a great way to introduce kids to astronomy, whether you're a teacher in a classroom or a homeschool parent.

Homeschool Science Experiment: Hovercraft. When you slide a hockey puck on the street, it quickly comes to a stop. Take that same puck and slide it over a sheet of ice and you'll find it zooms a lot farther. What gives? This experiment is great for teaching kids about air-cushioned vehicles and air pressure. www.youtube.com/...

Homeschool Science Experiment: Disappearing Glass Beaker. We're going to bend light to show the magic behind a popular optical illusion by using a cup of liquid as a lens. When a beam of light hits a different substance, it bends as it travels through the new substance. The speed that the light travels at and the wavelength (color) also changes. The amount of change depends on the index of refraction of the material. www.youtube.com/...

Homeschool Science Experiment: How to Make a Simple Catapult. The higher you pitch a ball upwards, the more energy you store in it. Instead of breaking our arms trying to toss balls into the air, let's make a simple machine that will do it for us. I really like this experiment because there's so much room for creativity and new ideas. www.youtube.com/...
