What are the Benefits of Doing Science Experiments During the Summer?
There are many benefits to doing hands-on science experiments over summer break.
The main one is that the warmer weather makes it possible to do these labs outside. This helps minimize the mess and gives kids the chance to work on large, messy science projects (aka more fun).
When you combine the outdoors with science, you create a unique learning experience that gets kids engaged and excited.
Summertime experiments offer tweens an opportunity to explore new topics in a more relaxed setting. They get to learn at their own pace and dig deeper into scientific concepts.
And as a bonus, letting tweens work on these fun and simple projects is a great way to keep their bodies and minds active and engaged when school is out.

How to Stay Safe During Science Experiments
With all experiments, it’s important to keep safety in mind, even if working outdoors. Here are a few tips for making sure your teen stays safe while working on any experiments:
- Always read the instructions carefully and follow safety guidelines.
- Place all experiments on a flat surface in an open area.
- Make sure your child is wearing the safety gear, like goggles and gloves for their experiment. (Many of the experiments below don’t require specialized gear.)
- If they’re using any hazardous materials, take time to familiarize your older kids with their safety protocols.
- Supervise as necessary.
By following these safety tips, you’ll be able to give your child the opportunity to explore without worrying.
Summer is a great time to head outside with your tweens to work on some exciting projects. And by following the points above, you can make sure everyone stays protected while learning.

Summer Science Materials
While many of the science experiments below use common household items, you’ll also need to pick up a few items that you don’t have on hand.
Aside from a couple of specialized products, you should have no trouble finding the simple supplies you’ll need online or at a local store. Some will even be at the Dollar Store.
Here are a few things to keep in your science box for when you want to work on an experiment. Note that this isn’t an exhaustive list.
- Latex Balloons
- Bubble Wands
- Baking Soda
- Vinegar
- Film Canisters
- Clear Sheet Protectors
- Iron Oxide Powder
- Borax Slime Activator
