Is it Christmas time already? Let’s create some homemade crystal ornaments with the kids. Kids will learn some science while decorating the Christmas tree with ornaments they create. In this experiment, we will use a saturated solution made out of Borax powder. This is a perfectly safe experiment for kids under adult supervision. You can …
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 …
We normally don’t play with fire (for obvious reasons). But here is a experiment I didn’t expect to be so easy and so much fun to do. At the same time, the results are so hard to understand, with, sadly, much misleading information on the internet. As always, adult supervision is required! THERE IS FIRE INVOLVED Why The …
Did you know that you could easily make a battery at home? You can do that by using lemons. Yes, lemons! Lemons are sour and carry a lot of citric acid. Of course, they cannot power your refrigerator or a toy car. But they contain enough energy to power a small LED light and make …
What Is Plastic Made Out Of? What happens when you mix milk with vinegar? What is plastic made out of? What do stone, buttermilk, yogurt and cheese have in common? So many questions I had in mind after researching for this milk curdling experiment. There are various experiments and articles online that indicate mixing milk with …
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 …
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 …
Newton’s first law of motion states that objects have the tendency to retain its motion or the lack of. If a body is at rest, it has the tendency to remain at rest; If a body is moving, it tends to keep moving in a straight line at a constant speed. This is also called …
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 …
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 …
The idea of creating something beautiful and unique out of ordinary materials is a lot like magic. One great example of this is growing your own crystals. And you can grow them into a rainbow. All you need to do it is a little bit of time, patience, and a few basic supplies. This crystal …
Electricity is all around us. We use electricity everywhere in our daily lives. We use it to light our rooms, run our TVs, power our phones, and charge our laptops. Do you know how electricity is brought to our homes? And do you know why flipping a switch can turn on or off the light? …
Electrical devices such as refrigerator, television and vacuum cleaners require electricity to operate. Do you know how electricity is created? And how do batteries operate a motor? Electricity is created using magnetic field. If you have a strong magnet and a battery, you can make a simple homemade motor. Try this very cool experiment. And …
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. Baking bread is full of teaching moments. Try …
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 …
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 …
Playing with an air canon is always fun. You can use it to propel little tissue balls with it You can also have a race to see who can make the balls fly the farthest. You can also make a smoke ring with it. Air canon moves the air. It’s normally hard to see how …
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 …
