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…
Have you tried our popular experiment “Why is the sky blue?” experiment? Now the next question is, “If the sky normally looks blue, why are sunsets orange in color?” From the last experiment, we know that when light (representing the sun) passes through a clear fluid (representing air) holding small particles (representing dusts), blue is scattered…
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…
Spatial reasoning is an essential skill for math learning and can be acquired through training and practice. Here are a few preschool geometry activities that can help kids learn spatial concepts. Let’s start with learning shapes by create 2-D and 3-D shapes from scratch in a spatial relationships preschool activity. By constructing each shape one side at a…
What Is Water Cycle? Water cycle is also known as hydrologic cycle or hydrological cycle. It describes how water moves continuously on Earth. Water loops through different stages – evaporation, condensation, precipitation and flow. It then goes back to the evaporation stage. The whole cycle starts all over again and hence the name “water cycle”. Water Cycle…
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,…

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….
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…
In an analysis of 6 studies including more than 35,000 kindergarten-ready children, it was found that comprehension of the world was the strongest indicator of the kid’s future academic performance. Comprehension or general knowledge of the world is a very broad category, but it basically means common sense in daily lives. It is not surprising that…
Toddler’s fine motor skills is one of the strongest predictors of the child’s future academic achievement. Fine motor skill is the ability to control hands and fingers. They are needed for writing, playing with small toys, doing puzzles, cutting with scissors, tying shoelaces and more. At school, kids are expected to learn to write new…
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…
Shape Activity For Preschoolers This shape activity for preschoolers requires very simple materials. It is the perfect project for little kids. They can exercise their fine motor skills. They will also learn to visualize different 3 dimensional shapes. Note that this project requires a lot of eye-hand coordination. Recommend for children above 4 years old. These…
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…
Here is a simple physics experiment using a property called static electricity. Every object is made up of small particles called atoms. These particles are extremely small and you cannot see them without a microscope. There are two types of charges in every atom — positive change(s) and negative charge(s). Only negative charges are free…
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…
Surface tension is the glue that binds water into a cohesive sphere and the force that makes water bead up on a surface. It is one of the amazing properties of water. Surface tension in water is created by the attractive forces between the water molecules It can be broken up. In this experiment, we…
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…
After finishing the Hovercraft and Friction experiment, you will be left with an empty CD case. Here is an upcycling idea. The empty CD box can be used in this gardening project. Grow a little indoor greenhouse full of grass in you kitchen. Like most plants, grass needs water, soil, air and sunlight to grow….
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….
