Summer is the perfect time for science experiments!

On the one hand, the weather is excellent, which makes outdoor activities enjoyable. You have the freedom to explore, discover, and roam the great outdoors. Life is in full bloom; the forests and grasses teeming with life. Nothing activates scientific curiosity quite like exploring nature.

On top of that, young learners have a tendency to more or less completely block out academia during the summer. It's not their fault: school is tough on kids, and summer is a time in their lives when they get to simply play and be kids.

Enter, science experiments!

Science is, at its heart, play. These experiments don't feel like science and cleverly disguise learning behind "looking for bugs" or "shooting off rockets," activities that young learners will readily sign up for.

So strap in and get ready for seven awesome experiments that will heat up your summer and get your young scientists more excited than a high-energy atom!

1. Beat the Heat With a Solar-Powered Fan


Depending on where you live, summer can be hot.

Why build a fan to cool you down while flexing the old STEM muscles, a classic case of two birds with one stone. Figuratively speaking, of course. Good science never harms animals.

The 80mm, 3 bladed fan is an excellent, as well as economical, introduction to several important scientific concepts.

First off are photovoltaic (PV) cells and solar energy. Solar energy is one of the primary alternative energy sources working to make society cleaner and more sustainable. It is a crucial industry now and will become even more so in the future.

Stoking a curiosity for solar engineering now could help to inspire your young learner to be one of the scientists who change the future of energy!

The 2V, 130mA polycrystalline solar cell (54x54mm) comes ready with pre-soldered wire leads, so no need for soldering. Simply connect the wires to the pre-attached wire leads on the high-efficiency DC motor (type 300 1V-6V), and you're ready to go.

Another concept in this experiment is that of DC motors: converting electrical energy into mechanical energy through electromagnetic induction. It's fascinating here because you can directly turn sunlight into mechanical energy!

While the process of stripping and connecting the wires is reasonably straightforward, ask your future scientist how the rig is able to turn sunlight into a moving fan.

After allowing them to reflect for a bit, explain that sunlight enters the PV cell, takes in the photons from sunlight, then uses them to generate a flow of electrons. These electrons flow into an electromagnet in the DC motor, which is between another fixed magnet.

When an electric current enters a magnetic field, the particles are pushed by the magnetic force described in Fleming's left-hand rule. This causes the rotor to turn and the blades on the fan to spin.

Help inspire your young scientist to shape the future of clean energy while staving off the summer heat with this 'cool' solar fan experiment!

Learning Outcomes:
Engineering, DC currents, renewable energy, solar energy, electromagnetism, DIY, environmental science

2. Get Things Moving with a Solar Rover Kit


We're once again capitalizing on the plethora of solar energy available during the summertime.

However, this one cranks things up a notch while also bringing some recycling into the picture. Talk about a sustainability two-for-one!

The solar rover comes with all of the parts necessary for the body and PV connection. All you'll need is a recycled soda can (not included) and a small cross-headed screwdriver for the attachments.

The kit also comes with a fantastic instructor guide that will help craft an engaging and informative lesson around the fun experiment. It includes information on solar energy, PV cell efficiency, and discussion questions to stimulate some critical thinking.

Once again, touching on PV cells and the importance of solar energy, this experiment shows another practical application of solar energy: electric vehicles.

Use this as a lead-in for electric vehicles and companies such as Volkswagon and Tesla, paving the way for this exciting industry!

If you'd like to mix things up and explore other renewable energy options, there is a wind-powered rover as well.

Use both to show young scientists that there isn't any one single solution for the energy crisis, rather many exciting options we can explore and harness from the awesome power of nature.

Learning Outcomes:
Engineering, building, renewable energy, solar energy, wind energy, technology, DIY, environmental science, EVs

NGSS Standards:
MS–PS1-6, MS-ETS1, MS-ETS2, MS-ETS-3, 4-PS3

3. Harness the Beauty of Solar Energy With a Solar Print Kit and Solar UV Beads


Arts and crafts have been an integral part of the classic summer experience for generations.

Whether at summer camp or with friends at home, summer's freedom and fair weather provide the perfect setting to make beautiful arts and crafts!

Why not partner this classic summer activity with a bit of science?

The solar print kit includes 12 sheets of special solar print paper, which undergoes a chemical change when exposed to sunlight.

Two pre-printed stencil sheets are also included, giving your scientific artists a choice between the nature-themed shapes on the stencils or finding their own objects in nature to trace on the solar print paper.




Want to frame the beautiful artwork or send it out to friends and family? No worries, two frames and three blank notecards with envelopes are also included. Art, especially art made from science, is meant to be shared!

When thinking about classic summer arts and crafts, bead bracelets have to be one of the all-time favorites.

But why settle for dull, ordinary beads when you can harness the power of the sun with solar UV beads!?

Each of the 250 beads in the kit has photochromic chemicals in the plastic, which change color when exposed to electromagnetic radiation from the sun. This makes for not only a fantastic piece of jewelry but also a beautiful reminder to apply sunscreen and protect yourself from UV radiation!

4. Take Flight With a Giant, 50-foot Solar Balloon


Flying a kite is another classic summer activity, and we've given yet another scientific twist to your favorite summer classics!

Become the talk of the local park by taking this enormous, 50-foot solar balloon for a spin instead of a regular old kite.




Not only is it an excellent conversation piece at the park (as well as a bit of flex), this solar balloon also demonstrates buoyancy, convection, thermodynamics, and solar power. You can also use it to teach Pascal's Principle as well.

Solar balloons gain buoyancy when the air inside is heated by solar radiation. The heated air expands and has a lower density than the surrounding air, thus allowing the balloon to float through the process of convection.

Pascal's Principle explains why, even though different areas of the balloon experience more or less sunlight, the entire balloon floats uniformly.

Pascal explained that a change in pressure applied to any part of the enclosed fluid will be transmitted equally in all directions through the fluid.

A bit of bright direct sunlight on a calm, cool day will have your Solar Balloon soaring in a matter of minutes.

The kit comes with one 50 foot long by 29" diameter Solar Balloon, 400 feet of string, complete instructions, and a science learning guide as well.

Learning Outcomes:
Solar power, buoyancy, convection, thermodynamics, Pascal's Principle, Bernoulli's Principle

NGSS Standards:
MS–PS1-6, MS-ETS1, MS-ETS2, MS-ETS-3, 4-PS3

7. Blast Off With a Pump Rocket Kit, or Take Things to the Next Level With the Cosmic Rocket Kit


Let's end with a bang!

Propulsion is one of the most exciting concepts in all of science. There is something visceral and awesome about watching a rocket take off or a fast car streak across the desert, especially when we are the cause of the spectacular event.

Leverage this exciting concept to help 'pump up' and inspire your future scientists!

For younger learners, there is the Sci-bits: Pump Rockets Kit. This kit includes a compressible bellow, a launch pipe with a base holder, and three soft foam rockets, which can be launched up to 20 feet in the air.

This is an excellent introduction to Newtonian rocket science, with velocity and trajectory up front and center in this absolute blast of an experiment. Try making a target and having your future rocket scientist adjust the angle and force at takeoff to hit the target!

Older learners might want to take things up a notch so, for them, we suggest the Cosmic Rocket Kit.

Touching on similar concepts as the pump rocket but utilizing the power of chemical reactions, this rocket uses vinegar and baking soda to launch the cosmic rocket up to 50 feet in the air!

Chemical reactions are another exciting scientific phenomenon, especially when it's an explosive reaction launching a rocket 50 feet into the air.

These two seemingly innocuous kitchen items react because one is a base while the other is an acid. In this case, baking soda is sodium bicarbonate (a base), and vinegar is diluted acetic acid. When they react to release the OH and H to become water, they also release carbon dioxide, which causes the solution to bubble and expand rapidly, much like shaking a can of soda.

The rocket, much like an unopened can of soda, contains that pressure, allowing it to build up until it is enough to send the rocket flying.




Whether getting pumped up with the pump rockets or really blasting off with the Cosmic Rocket Kit, these explosive experiments are sure to excite and inspire the next generation of rocket scientists!

Learning Outcomes:
Rocket science, Newtonian physics, pressure, aerodynamics, chemical reactions, physics, chemistry
