DIY SCIENCE EXPERIMENTS FOR KIDS

We love simple science experiments you can do at home or in the classroom.  I wanted to put together a kids science kit to show you how simple it is to try your own science experiments at home.

Most of our favorite science equipment for kids are super simple to find at the grocery store or the dollar store, and many items you may already have at home.

Of course, water is an awesome material for science experiments so make sure to try one of our awesome water science experiments! Grab a container and start filling!

These science experiments are perfect for the youngest scientist as well as great for an older child, just add in some journaling, graphing, making predictions, etc. Several ages can learn together if necessary. There is always plenty of room for creativity, discovery, and exploration!

1. ALKA SELTZER TABLETS

Start off your homemade science kit with a fizz and a pop!  We love using Alka seltzer tablets in our homemade lava lamps and to make these awesome pop rockets.

2. BAKING SODA

Baking soda, along with vinegar is one item for your science kit, that you will want to use again and again.  A baking soda and vinegar reaction is a classic science experiment and we have so many variations for you to try!

Baking soda is also an ingredient in our popular fluffy slime recipe!

Here are a few of our favorites…

• Sandbox Volcano

13. SALT

Salt is another must have item to add to your DIY science kit for kids.  Substitute salt for borax powder as we did, to grow salt crystals.  Try painting with salt for a bit of art and science! Learn about salt and ice with our ice fishing experiment. We also used salt for our Salt Water Density Experiment.

Sugar, like salt is another DIY science kit item that is great for experiments with water.  Why not make a rainbow in a jar or explore which solids dissolve in water.

16. VINEGAR

17. WASHABLE PVA GLUE

PVA glue is one of your must have slime ingredients for making homemade slime.  Clear glue, white glue or glitter glue, each one gives you a different type of slime. Plus, we now have our own 2 ingredient slime recipe just for glitter glue!

PLUS… SCIENCE TOOLS 

Our kids’ science kit is also filled with science tools and necessary science equipment. Dollar store cookie sheets, ice cube trays and small ramekins are always used to contain mess, test liquids and sort items as well as freeze ice!

I usually always set out a magnifying glass and often a hand mirror. We use tweezers and eye droppers often as well. No kids science kit is complete without a pair of safety goggles too!
