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…

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…

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…

Static Electricity and Water

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…

Soap Powered Boat Experiment

One day, my 4-year-old daughter asked, “What is science?” “Well, remember you always ask me Why — ? Why is the sky blue? Why is sunset orange? Why are bubbles round?” I answered. “Science helps us find out answers to these whys!” My daughter’s question came at the perfect time when I received the new…

What Is Surface Tension | Cool Science Experiment

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…

Hovercraft & Friction Experiment

Hovercraft & Friction Experiment

Friction is the force created when two objects move across each other to oppose the movement.  An object gliding on the floor stops because of friction. When friction is reduced, a gliding object moves faster, farther and for longer. This balloon hovercraft can fly across the floor because air has less friction than the floor. When…

Cartesian Diver Experiment (Video)

How do fish float and sink? This classic experiment is called Cartesian Diver, named after French scientist, mathematician and philosopher scientist, René Descartes. It demonstrates the principles of buoyancy and density and explains how fish dive or rise in water. Buoyancy: the force of buoyancy on an object is equal to the weight of the water displaced by that object. Density: if an object…

Finding Iron In Breakfast Cereal

Iron is an essential mineral to our body. It is found in every cell and is used to make hemoglobin, the substance in red blood cells that carries oxygen from your lungs to transport it throughout your body. If we don’t have enough iron, our body will show symptoms including lack of energy, shortness of breath, headache,…

How Many Drops of Water Can Fit on a Penny Surface Tension Experiment

Surface tension is a force that pulls together the outermost molecules of a liquid. It makes water form tiny beads on a leaf and hold a raindrop in the air. It is also why bubbles can form and then burst. Here’s a STEM challenge. This challenge is to see how many drops of water will…

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…

Toothpick Star Trick Science Experiment For Kids

Toothpicks are made of dry wood. Using the absorbing property of wood and the surface tension property of water, you can create a fun trick to impress your kids (or friends). In this simple experiment, we will turn broken toothpicks into an expanding star. Before you start, be sure to watch the video below. The…

2 Light Refraction Experiments

Refraction Of Light Have you ever noticed if you look through a glass of water, the image behind the glass sometimes looks funny or distorted? It’s like the glass of water is playing tricks on your eyes. The trick is actually created by the refraction of light. Light travels at different speed through different materials….

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…

Balloon Rocket Car Race | Propulsion STEM Activity

Propulsion And Newton’s Third Law How do airplanes fly in the sky, ships move in the water and rockets take off into the space? These movements all have one thing in common — thrust. Newton’s Third Law of action and reaction states that for every action, there is an equal and opposition reaction. For every force,…
