22 Ways to take science outside

Outdoor Science Experiments and Activities

Chemistry

Science can get messy. Take the activity outside and have an easy clean up.

Exploding Baggies – What do you get when you combine baking soda and vinegar in a plastic baggie? An expanding bag that pops! This classic science activity is best done outside.

Fizzy Coconut Lime Play Dough – Try this awesome fizzy dough. It’s soft and moldable. Plus it fizzes and foams when you add an acid like vinegar. You can play with this one inside or out but I recommend taking it outside because of the mess.

Frozen Vinegar: Cool Summer Science – Turn classic baking soda and vinegar play into a cool summer science activity with frozen vinegar!

Frozen Oobleck – We originally did this activity inside but it would great outside as well. Freezing the oobleck changes its texture and behavior and adds a whole new level of fun.

Easy Tape Volcano – We made a volcano out of tape and took it outside to set it off. A super quick activity to set up that will entertain until the baking soda and vinegar runs out.

Physics

Use the heat of the sun, wind, and other elements of nature in these physics investigations.

Temperature Experiments – Learn about measuring heat and practice using thermometers with these fun activities. You can do both experiments outside.

Exploring Temperature and Color – Conduct an experiment to test how color affects the temperature of an object. This experiment is simple enough for many preschoolers to complete on their own.

Jumping Experiment – This is my favorite simple experiment for toddlers and preschoolers. All you need is a measuring tape and some space to jump.

Explore Density – Take the classic sink or float activity outside. Use rocks, leaves, flowers, and whatever else your kids find.

How to Make a Parachute – Experiment and find out what makes the best design. We launched our parachutes from a step ladder outside. You could also release them from a deck or playground equipment.

Measuring Practice with Inch by Inch – After reading Inch by Inch by Leo Lionni, we grabbed a ruler and headed outside.
