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 one of the amazing properties of water. Here is an excellent experiment demonstrating how water surface tension works. It’s a very cool science activity for little kids. What you need black pepper a plate or bowl water liquid soap (I used liquid dish soap) Steps Fill the plate with a thin layer…
Egg Drop Inertia Science Project
This amusing experiment demonstrates Newton’s first law of motion. It was so much fun that my overactive kid wanted to do it again and again and again. Why Why does the egg fall right into the glass while the paper roll and the pan flies sideways? This can be explained by Sir Isaac Newton’s First Law of…
Sugar Water Rainbow | Density and Air Pressure Experiment
Why 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…
The Science Of Bread Baking
I wanted to show my daughter that science was in our everyday life. 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. Here is a great example — bread baking. Baking bread is full of…
How To Keep Crackers Dry Underwater | STEM Challenge
We like dunking cookies in milk before eating them. But we don’t like doing this to crackers as they will become soggy. Why Even though the crackers and the paper towel were completely underwater, they both stayed dry! This is because an empty glass is not really empty. There is air inside. The air inside the glass is…
