## Build Marble Roller Coaster | STEM

Have you ever wondered why the string of roller coaster cars is pulled up to the crest of the tallest point on the roller coaster before rolling downhill to the loop? Why do the cars not fall off even when they are upside down inside the loop? The roller coaster is a great demonstration of the law …

## The Science Of Bubbles – Can You Poke A Bubble Without Popping It?

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 …

## Magnetic Field Force Experiment

Magnetism is invisible, but it’s all around us. There is a giant magnetic field on Earth. But in this experiment, we will see a smaller version of magnetic field. We will use iron filings to see the magnetic field in 3-dimension. (Here’s an example on 2-dimensional magnetic force field.) Magnet attracts iron and the magnetism …

## What Makes Ice Melt Faster? Salt Melts Ice Experiment

Why do people put salt in snow? That’s because salt can make ice melt faster. Ice melts at a specific temperature called the melting point. Salt makes snow melt faster by changing ice’s melting point. Here is an experiment showing how salt achieves that. Using salt, you can pick up a piece of ice with …

## Magnetic Poles For Kids | Science Experiment

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 …

## Color Changing Flowers Science Project

Do you know that flowers can drink up water and change their own colors into the color of the water they drink? Flowers and plants drink water through their roots. In cut flowers, since there are no roots, water travels from the cut directly into the stems and travels to the petals and other parts …

## Photosynthesis And Respiration In Plants

What is Respiration in Plants All living things use a process called respiration to get energy to stay alive. Cellular respiration in plants is the process used by plants to convert the glucose made during photosynthesis into energy which fuels the plants’ cellular activities. On the other hand, photosynthesis is the process where light energy …

## How To Make A Rainbow – Simple Science Experiments

How Are Rainbows Formed? Sunlight or white light is a mixture of all the rainbow colors. The different rainbow colors are essentially mixed together to result in a white color. You may wonder why when you mix all the different colors of paint together result in black instead of light. That is because light mixing …

## Why Are Sunsets Red Orange? Science Experiment | STEM (Video)

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 …

## Grow A Crystal Angel Ornament – Science Experiment

One of the most salient properties of water is its ability to dissolve other materials. In this experiment, you will dissolve Borax powder into the water to create a saturated solution. A solution is saturated when no more powder can be absorbed. Water can dissolve more powder when it is hot. In this experiment, you …

## Cool Rainbow Color Experiment

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 – Visualize Shapes Through Play

Spatial reasoning is an essential skill for math learning and can be acquired through training and practice. Here are a few activities that can help kids learn spatial concepts. Let’s start with learning shapes by create 2-D and 3-D shapes from scratch. By constructing each shape one side at a time, you will have a better sense of …

## Water Cycle

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 …

## Why Is The Sky Blue? Simple Science (Video)

The Blue Sky On a clear day, the sky is nothing more than the air in the atmosphere. The air itself or the sunlight doesn’t seem to contain any color. So why is the sky blue if sunlight is colorless? The sky is blue due to the scattering of light by tiny particles in the …

## Center of Gravity Experiment

Gravity is a force that sucks everything to the ground and keeps our feet firmly planted on the floor. What about center of gravity? Have you ever heard of it? The center of gravity of an object is the point around which all weight is balanced. In humans, it is often referred to as the …

## Fun Math Games – Learning Shapes And Patterns Activities

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, …
