In your microwave, we’ll use food to create the fourth state of matter. Please take note that this is NOT the plasma that doctors refer to when talking about blood.
Put a bar of soap in the microwave and watch it expand to 6x its size right before your eyes! The Expanding Ivory Soap Experiment is a classic science activity that will fascinate kids and grown-ups alike.
The Microwave Ivory Soap Experiment is one of my favourite science experiments for kids because it’s so quick and easy, and it yields such fascinating results. There’s almost no prep required, and you don’t need any fancy supplies. All that’s required is a bar of Ivory and a microwave oven.

Have you ever heard about density?
Density is basically how tightly packed atoms are. (Mathematically, density is mass divided by volume.) For example, take a golf ball and a ping pong ball. Both are about the same size or, in other words, take up the same volume.
However, one is much heavier, has more mass, than the other. The golf ball has its atoms much more closely packed together than the ping pong ball and as such the golf ball is denser.

Things like lenses and mirrors can bend and bounce light to make interesting things, like compound microscopes and reflector telescopes. Telescopes magnify the appearance of some distant objects in the sky, including the moon and the planets. The number of stars that can be seen through telescopes is dramatically greater than can be seen by the unaided eye.
Vanishing Styrofoam Cups – In our Vanishing Styrofoam Cup experiment, pieces of Styrofoam will vanish. Is it magic? Or is it science? Read on to find out!
Have you ever seen a lava lamp?
This lava lamp experiment is super cool! Your kids will love exploring colored water and oil, but a surprise ingredient will make this science activity even more exciting! It’s always a hit with the kids. So grab a few household supplies and give this lava lamp science activity a try!
Which candle goes out first?
Two candles of different heights are extinguished by putting a glass over them. Which one will extinguish first? What is the reason if one of them goes off first? Let’s find out by actually performing this experiment and learn the science behind it!
