Second grade science experiments and science fair project ideas
Have you ever wondered where metals such as iron, copper or nickle come from? We can buy them from hardware store. But where did the store get them from? Do you need to be an iron ore miner to find them? Turns out a lot of metals can simply be found in soil. Try this simple…
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…
Silkworms are native in China. They spin cocoons of fine, strong and lustrous fiber which can be used to produce raw silk. Silkworms are domesticated insects which means they cannot survive in the wild by themselves. The practice of breeding silkworms for silk production has existed for at least 5,000 years in China. 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…
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…
Normally, paper clips do not fly into a hand that hovers over them. That is because the gravitational force pulls the paper clips toward the Earth. In the experiment, you will use a strong magnet to make the paper clips come upward into your hands. It’s almost like the paper clips can defy gravity. But…
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…
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…
Patterning is fundamental to mathematics because all math are virtually patterns and structures. Mathematical relations and transformations result in patterns and abstraction. It is therefore critical to children’s development of mathematical reasoning. The integration of patterning in children’s early learning can promote such development. There are many types of patterning: written symbols (e.g. ABCABCABC…), numerical (e.g. 1,…
