Pressure is the amount of force that is exerted on something. Gravity causes pressure naturally. Water pressure is the force created by the weight of water. When you jump into a pool, you can feel the force pushing around you. Water pressure can push water through pipes and hoses. Here is an easy water pressure experiment. …
Diffusion is the process of something moving from one place to another in a medium such as air or water. It’s a common process in everyday life. When mom is cooking pancake in the kitchen, you can smell it all the way upstairs in your bedroom. If you put a drop of water color into …

Silkworm …
What do you do when there is an oversupply of candies in the house, like the day after Halloween? (yeah, right.) Candy science experiment, of course! This experiment is really spectacular to watch, but the science behind is pretty complicated… actually, I haven’t found a definitive scientific explanation agreed by all authoritative scientists yet. But …
This is a fun and simple way to teach kids about light and the basics of how light works. Under sunlight, put a toy on a surface or a piece of paper. Then watch as the shadow is created on the paper, floor or wall. Light travels in a straight line (as far as our …
Can you make rain in your own home? This is a rain making experiment that simulates how rain forms. A simulation is an imitation. This experiment mimics the rain making process in nature, but it’s not the real process. We can then closely study it. Unlike other rain making experiment, this one is super simple. …
Summer is here! Kids love bubbles. And they adore bubble science experiments. It’s one of their favorite summer activities. Playing with bubbles using a simple wand is fun, but here is another cool way to blow bubbles. They are called bubble snakes. Bubble snakes are easy to make and provide tons of outdoor entertainment. Take …
Do grapes sink or float? Grapes can do both. Whether a grape sinks or floats depends on its density relative to the water it’s in. An object’s buoyancy is determined by its density compared with the density of the surrounding water. Density of water can be changed by adding salt. Let’s try this experiment to …
Here is a hands-on STEM exercise for kids. It is fun for the kids and very easy to set up. Use everyday items around the house to illustrate science ideas and theories. Explore volume, shape and size The size of a three-dimensional space is called volume. One simple way to find out which container has a bigger …
Compasses are a very important tool explorers. They are useful when you go hiking, camping or other outdoor activities. They help you identify directions so you won’t get lost. Compasses work because there is a giant magnetic field surrounding us on Earth. Did you know that it’s very easy to make your own compass at …
Little kids love soap bubbles (a lot of grownups do, too!) Blowing bubbles, chasing them, trying to catch them and eventually popping them can provide hours of fun for kids. It’s one of many children’s favorite outdoor activities. Do you know why bubble pop when they are touched? Is it possible to touch a bubble …
Playing with magnets is always fun. We bought some very strong magnets recently and they are perfect to show what magnetic field looks like. Magnet attracts iron and the magnetism can act through many materials such as paper. When iron filings are spread over the magnets, you can see the outline of the magnetic force or …
Kids are fascinated by rainbows. A rainbow is the result of light reflection, refraction and dispersion through water droplets in the air. A spectrum of rainbow color can usually be seen after rainfall when the air is full of moisture. Among the spectrum of colors, red, blue and yellow are primary colors. They can be combined …
