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 …
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 …
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 …
