Color Science & Art | Coffee Filter Flowers

Is black really black? What happens when all the rainbow colors blend together? We will be able to answer these questions after doing some science investigation. In this experiment, we will use coffee filter to investigate color properties. We will make a beautiful bouquet of flowers along the way, too! It’s a combination of fun experiment …

Make A Square Bubble

Water molecules (and also liquid soap and glycerin molecules) tend to stick to themselves. This cohesive force creates surface tension. (Note: Water by itself doesn’t form long lasting bubbles because a thin layer of water molecules evaporates too fast. By adding soap and glycerin, the “skin” of the bubble is more stretchy and water is …

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

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 …

Does Water Conduct Electricity? Simple Experiment

“Don’t touch a switch with wet hands!” We were all taught that since we were little kids. It does seem like water can conduct electricity and that is why we shouldn’t touch any electrical outlet or switches if our hands are not dry. Does water really conduct electricity? Let’s find out by doing a simple controlled …

Weathervane | Weather Science

Summer is more than half way through. Soon it’ll be fall and the change in seasons is usually accompanied by curious questions about the weather.  Since autumn is often windy, one inevitable question is: Where does wind come from? This question has two meanings: a) how is wind created? and b) which direction does the wind …

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 …

Sugar Water Rainbow | Density and Air Pressure Experiment

Density is the amount of substance (mass) within the volume occupied by the object. If two cups have the same amount of water (i.e. same volume), the one with more sugar is denser than the one with less sugar. Buoyancy is determined by relative density. The solution with less density floats above the solution with …

Bubble Snake Experiment

Summer is here!  Kids love bubbles. 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 full advantage of this wonderful weather and …

How Are Ocean Currents Formed | Water Convection Experiment

How Are Ocean Currents Formed Ocean currents are formed in several ways. They can be created by wind, by gravity, by events such as earthquakes. They can also be made by density differences in the water. Density in the water changes when temperature or salinity varies. In this experiment, we will investigate how temperature can affect …

Do Grapes Sink Or Float? | Salt Water Density Experiment

Do grapes sink or float? Grapes can do both. Whether a grape sinks or floats depends on its density relative to the water it’s in. An object’s buoyancy is determined by its density compared with the density of the surrounding water. Density of water can be changed by adding salt. Let’s try this experiment to …

Easy Science Experiment: Gravity And Magnetism Activity

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 …
