Tornado in a Glass

By Rookie Parenting Science Updated 05/17/2020

Glass with tornado shaped water inside and sparkle glitters at the bottom

A tornado, also called twister or cyclone, is a violent rotating column of air extending between the Earth’s surface and the base of a thunderstorm. This vortex of wind, usually funnel-shaped, can be very destructive. It can destroy large buildings, uproot trees, drive sticks into trees and hurl cars hundreds of yards away. In this experiment, we will make…

Rising Water Experiment

By Rookie Parenting Science Updated 03/19/2020

We normally don’t play with fire (for obvious reasons) But here is a magical 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…

Make A Square Bubble

By Rookie Parenting Science Updated 05/15/2020

Can you make a square bubble? We’ve all seen sphere-shaped bubbles. They are like balls in shape. But can you make a bubble that looks like a block or a prism? Why Water molecules (and also liquid soap and glycerin molecules) tend to stick to themselves. This cohesive force creates surface tension. (Note: Water by…

Soap Powered Boat Experiment

By Rookie Parenting Science Updated 05/15/2020

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…

Egg Drop Inertia Science Project

By Rookie Parenting Science Updated 05/15/2020

egg placed on the top of the paper roll.

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

By Rookie Parenting Science Updated 05/15/2020

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

By Rookie Parenting Science Updated 05/15/2020

The Science Of 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

By Rookie Parenting Science Updated 05/15/2020

crackers, paper towel and glass of water

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…

Can A Raw Egg Grow? | Science Experiment

By Rookie Parenting Science Updated 05/15/2020

two raw eggs, one before experiment and one after experiment

Why 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…
