How To Keep Crackers Dry Underwater | STEM Challenge

Air can exert pressure on other objects. That force is called the air pressure. After shaking a soda can and open it, the soda explodes. That’s air pressure at work. But you don’t have to use a can of soda to see how air pressure works. There are other, less messy ways. In this air…

Can A Raw Egg Grow? | Science Projects With Eggs

In this experiment, we first see an acid-base reaction. Eggshells contain calcium carbonate which is a base while vinegar contains acetic acid. When you submerge an egg in vinegar, an acid-base reaction causes the calcium carbonate to break down into their calcium and carbonate parts. The calcium ions (as in calcium acetate) stay dissolved in…

Thunderstorm Convection Experiment (Video)

Even though there is a severe drought in the area where we live, thunderstorms are still a common spring occurrence. I have shown my kid how rain was created before. Now she’s curious how thunderstorms form and what causes them. So what is a thunderstorm? A thunderstorms is a storm with lightnings and thunders. What causes…

Refraction of Light in Water Experiment (Video)

Have you noticed that things look a little funny when you see them through a glass of water?  Some of the aberrations are caused by the imperfection in the glass production. But there is more to it. Refraction is the bending of light as it passes from one transparent medium into another​1​.  This bending by…

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…

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…

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…

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…
