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.
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. http://www.youtube.com/watch/?v=NmnqdEW2eQs
Disappearing beaker experiment: watch how to bend light and make objects disappear!
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 :-)
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.

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.
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
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: 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/...
