Science is Cool!

Science Kits and DIY Experiments For Kids!

Learning about how the world works, especially in nature was my first thing to do growing up. I loved studying rocks and getting my hands dirty looking at worms in the mud.

Here are some toys, activity kits, and at-home experiments for your kids:


Create your own crystals and watch them grow with either Thames & Kosmos’ Grow A Crystal Pink or Blue or The Magic School Bus’ Growing Crazy Crystals Science Kit!

Compare shapes and sizes of different crystals like salt or sugar or even ice! Grow them in the shape of a tree or make a beautiful garden of crystals! You can even make your own rock candy!

Renewable Energy!

Learn about the power of water and how it can be used as an energy source with the Hydropower Experiment Kit by Thames & Kosmos! Build your own waterwheels, sawmill, or hammer mill, and watch them harness the energy of moving water! Study waves, tides, rivers, surface tension, and pressure and conduct different experiments.

Diggin’ & Excavating

Pretend you’re a Paleontologist and dig for the bones of dinosaurs that roamed the Earth millions of years ago! Excavate fossils of different dinosaur species like a Velociraptor, T-Rex, or a Brachiosaurus (my favorite dinosaur because of The Land Before Time movies) with KidzLabs Dig A Dinosaur Skeleton! Unearth nature’s greatest secrets and see them come to life!

Or excavate and assemble a glow-in-the-dark dinosaur model with Thames & Kosmos’ DIG IT! Dinos!

Dig for gemstones, rocks, or fossils with Thames & Kosmos’ DIG IT! Rocks! Fossils! Collect all 12 different minerals, rocks, and fossils from Amethyst, Quartz, Red Jasper, and Obsidian.

Conduct fun-filled, illuminating, and educational chemistry experiments with glowing substances and neon pigments with Thames & Kosmos’ Glow-in-the-Dark Science Lab! Use a UV flashlight to make neon colors come to life and see their vibrance, create neon glowing sidewalk chalk, and even make a flower glow in the dark.

At-Home Experiments:

Make water walk! Watch water move from glass to glass with this cool DIY experiment, Walking Water!

All you need is:

  • 6 identical cups or jars (make sure they are clear)

  • Paper towels

  • Food coloring


1. Fill 3 of the 6 cups with about 3/4s of water.

2. Add a few drops of food coloring and stir.

3. Place the empty cups between the colored water cups.

4. Fold the paper towel lengthwise until it’s about 1 inch wide.

5. Put one end of the paper towel in the cup with the colored water and the other end in the empty glass (make sure the paper towel doesn’t stick up in the air)

6. Leave everything alone and check back occasionally to observe the progress.

Eventually, after a few minutes (could take up to 20/30 minutes to complete), all the cups will be filled with the same amount of water!

Eggshell Geodes

Create your own geodes by using alum powder, water, and gel food coloring to turn eggshells into colorful geode crystals!

DIY Geode Crystals Supplies:

  • Alum powder

  • Eggshells (plastic works too, but the crystals are smaller)

  • Water

  • Gel Food coloring

  • Mason jar

Geodes are formed from sedimentary or volcanic rocks. These rocks are usually pretty ordinary looking, but beautiful crystals are within these hollow rocks. There’s no way of knowing what’s inside until you crack them open! You might find quartz or amethyst.
