DIY Science Activities and Experiments


Sink or Float All you need for this activity is a water-filled container and some toys that can get wet. Ask your child if they think the toy will sink or float and what will happen to it. Explain during the activity how weight and the water work together.

Scavenger Hunt  I absolutely love scavenger hunts for the kids. You can create your own or use a free printable online. It’s easy if you make your own to add in items for the kids to find such as certain rocks, bugs, plants etcetera. Then you can teach them about those things. See who can find the most and maybe they win a prize or get to pick the next activity.

Sensory Bins You can make a sensory bin quick and easy and have different themes. Dinosaur toys and sand make a great Jurassic theme. Your options are unlimited and the kids love getting to play with all the different items.

Sensory Jar You can make these for any theme. If your kid has a favorite color the jar can be things of that color. Or you can make a spring jar using flowers and glitter. Fill a jar with water, add your decor (glitter, food color, leaf, etc.) then put the lid on and observe the beauty.

Rock Collector- Find different sized and shaped rocks and see if there are different types to identify. Then paint the rocks and collect them. Your kids can always keep adding to the collection.

Pasta Jewelry- I remember making pasta jewelry as a child, it’s a really fun and easy activity. Simply layout different size and shaped pasta and color them (measure 2 cups of desired pasta, add to a plastic zipper bag, mix 1/8 of vinegar to a cup add 20-30 drops of food coloring and stir, add this to the bag. Mix the pasta around in the bag then spread out on parchment paper to dry several hours or overnight). Once your colored pasta is dry, place it on a pipe cleaner and add pasta and beads until you fill up the pipe cleaner. Enjoy your new jewelry!
