Nowadays, we have clocks and watches that tell us when to wake up and leave for work. Before the invention of clocks, how did people tell what time it was? Sundials have a long history of being used to tell time. As far back as 1500 B.C., ancient Egyptians used a sundial or “shadow clock”….
Tornados can be devastating. It can destroy large buildings, rip roofs off of houses, uproot trees, drive sticks into trees and hurl cars hundreds of yards away. They can even pick you up and literally drop you somewhere else. A tornado, also called twister or cyclone, is a violent rotating column of air extending between the Earth’s surface and…
Table of Contents What Is The Scientific Method? Scientific Method Steps Scientific Method Examples – Zoey and Sassafras Download Scientific Method Worksheet What Is The Scientific Method? The scientific method is a systematic way of studying the world in a scientific manner. It allows scientists to minimize errors and increase confidence in the results of…
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…
Friction Experiment This experiment is about friction. Friction allows us to walk on the road instead of sliding on it. It also lets us pick up a piece of paper or a glass of milk. You can also pick up rice grains using a pair of chopsticks all because of friction. In this experiment, you…
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…
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…
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…
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….
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…
Did you know that oil and water are not the same density? That is why oil and water don’t mix. However, they will add up to something that’s even more fun. It’s a lava lamp! All you need are a few simple household items and a tall clear glass. Density is the amount of matter…
3D drawing is a visual illusion trick kids will love to learn. In this project, we will be learning about the properties of depth perception. You will draw an object that looks like it’s jumping out of (or into) the 2D piece of paper. See how your eyes can perceive images differently when the picture…
Water science experiment is always a hit for the kids. One of the coolest summer activities for kids is building a paddle boat. Building a paddle boat is so easy and so much fun. The boat makes a great toy. You can use it on a pond, in a pool or even in a bathtub….
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…
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…
Have you ever wondered why water sticks to your skin? When you jump into a ball pool and come out, none of the balls will be stuck on you. However, when you come out of a pool full of water, all the water doesn’t leave your skin immediately. Instead, it drips and you stay wet…
Can water defy gravity and float in midair? Not really, but with some help, it can appear to be. Air molecules, which we cannot see with naked eyes, are constantly moving and bombarding everywhere. The resulting force is air pressure. Normally, the air pressure above and below the water are the same. When equal forces…
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,…
Did you know that water can play tricks on your eyes? This experiment is incredibly simple and requires only a glass, water and a coin of your choice. It demonstrates a special property of water, called light refraction. If you put a coin inside a glass of water, you will be able to see that…
Science is all around us. Oftentimes, we apply the principles of physics, chemistry or biology without even knowing. We can all be scientists and we are by observing and studying carefully what happens around us. Baking is a good example. Kids love baking and playing with the dough. Making bread with kids is full of teaching…
