Chapter 3: Thermal Conductivity of Metals

Have you ever touched something?

That became hot enough to burn you only moments after it was cool to the touch? This can happen when you stir a pot of soup on the stove with a metal spoon or roast marshmallows over a fire with a metal rod. So what explains why it’s a better idea to stir your soup with a wooden spoon and roast your marshmallows with a wooden stick? Objects made of metal can quickly conduct unwanted heat right up to our hands!

Fun with electrostatic charges

Bending of Water!

Did you see bending of Water from a Water faucet? Static electricity can be a problem whenever the humidity is low. It causes shocks and makes dust stick to surfaces, and it can literally make your hair stand on end. In this experiment, you will see that it also can move things around.

Grade 4: Chemical Reaction | Water Volcano

Have you ever see Water Volcano?

Water Volcano. The mixing of the vinegar and baking soda produce a volcano like foam. The answer? The mixing of the vinegar and baking soda produce acid-base reactant. The reaction creates carbon dioxide gas that bubbles up from the mixture. This trick is the perfect rainy day activity for all ages (adults too!). The possibilities are endless – so grab a glass of water and start making magic!

Grade 5 | Physics | Heat Transformation

Water Condensation Experiment

Water is always moving through the water cycle. When water enters a warm air mass, such as air heated by the sun, it rises! When the water rises up into the atmosphere it collides with the much colder air at the top of our atmosphere. But that cold air is not able to hold as much water as warm air. This causes condensation to occur and eventually RAIN! This is what happened when we put the cold ice on top of the warm water. The warm, moist air in the jar condensed and formed water droplets or what kids can think of as rain once interacting with the cold ice!

Grade 6: Chemistry: Chemical Reaction Part 2

Red Cabbage Science Experiment for Kids Chemistry

I’m not a big fan of cabbage except for when it’s used for science! Food science is super cool and is awesome for kids. This isn’t the sweetest smelling science experiment we have done, but once you get past the smell this cabbage science experiment is fascinating. Amazing chemistry for kids with simple food. So over here we say, don’t stop playing (learning) with your food!

Hot and cold water diffusion experiment

Hot and cold water diffusion

Have you ever colored a picture with marker and noticed that two touching colors begin to bleed together? In class, do you typically sit evenly spaced or all scrunched together? Although one of these refers to chemical properties and the latter social interaction, both are examples or diffusion.

Simple Microscope Experiment

Simple Microscope Concept

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.
