A tasty experiment for the summer, this can help teach kids how mixing base liquids with acid creates a chemical reaction – but it results in something that you can enjoy at the end! 

30. Magic Milk 

This simple experiment needs a few items; milk, dish soap, and food coloring. This is a super colorful and fun thing to do and can help show kids how molecular behavior might work, how surface tension works, and a little bit about an object’s density.

31. Walking On Eggs 

Another experiment that can show the power of weight distribution is walking on eggs. Show your students how something so fragile can withstand body weight when in large numbers.

32. Create A Hydraulic Elevator 

This experiment sounds more complex than it actually is. You just need to use some sticks and large medicine droppers. It’s a classic experiment that many STEM teachers have used in the classroom before.

33. Demonstrate Inertia 

Newton’s first law of motion can be demonstrated pretty easily, and it’s never too early or too late to show students how it works! 

34. Grow Your Gummy Bears

When it comes to students and science, what better way to teach them than using candy ? Using all areas of the major sciences, you can turn little gummy bears into big gummy bears! 

35. The Disappearing Egg Shell

Students of all ages enjoy watching this experiment , and it’s helpful to show them the ways that chemical reactions operate.

36. Coca-Cola Tooth Experiment 

This is a classic experiment that can help show students the effects of sugary drinks on their teeth. When your students are young and losing their baby teeth, ask them to bring in a tooth and show them the horrible effects in a jar! 

37. Small Tornado In A Bottle

Most of us performed this experiment when we were students, and it’s super fun to keep it going with your own students. Demonstrating centripetal force by creating a water vortex in a bottle is awesome! 

38. Make A Bag Leak-Proof

Another experiment that demonstrates polymers, you need a plastic bag, some water, a sharp pencil, and some patience – and you can show kids the seemingly impossible!

39. Make A Non-Newtonian Fluid 

There are substances out there that get firmer when pressure is applied to them, and these are known as non-Newtonian fluids. It’s really intriguing to see how fluids can behave in such ways, so your students are bound to get a kick out of this.

40. Demonstrate Capillaries

You can show kids how our capillaries function using items you can find pretty much everywhere. It’s super cool and colorful and you’re bound to excite everyone with this in the classroom.

41. Make Candy Rock 

Students, candy, and rocks – they go hand in hand! Your students will love to create their own candy rock and watch as the rock crystals grow.

42. Make The Super Bubble

You can show students how to make a better version of bubble mixture to create much larger bubbles, called superbubbles! 

43. Frozen Vegetable Oil Paintings

Here’s another classic experiment that most kids have conducted when they were in the classroom. It’s a fun way to show kids how some liquids behave when they are frozen, and as vegetable oil behaves differently – you can make awesome paintings! 

44. Make An Ice Magnifying Glass 

This experiment is pretty simple, but we like to add something more fun to it. Once you have made your ice magnifying glass, show your students how glass behaves underwater by designing a real magnifying glass (do not allow them to do this though).

Glass under water can be cut and sliced in much different ways than above the surface, so you can easily create your own glass designs to show your students in a safe way.

45. Can Eggs Float?

Finally, on our list, we have the experiment that has shown students for years how eggs can float on water if salt is added to the liquid. It’s a simple way to explain density, and it’s always a good idea to bring in the Dead Sea example.

The Dead Sea is so salty that people can simply float on its surface, but it’s also deadly because if you turn around – it’s difficult to get your head out of the salty water! 

Things To Remember

There are always things you should remember when it comes to these sorts of experiments. Some are much more obvious than others, but it’s always important to ensure we’re on the same wavelength. These include the following.

Safety 

Conduct a health and safety risk assessment before you carry out any experiment, and always be aware of any safety equipment you and your students may need to wear. Be sure to take reasonable care with all of your experiments (and best to do a trial run first!).

Reinforce Learning 

It’s all fine and good demonstrating the experiments, but you must ensure that you reinforce the student’s learning by asking questions at the end of the lesson. It’s also wise to set some theoretical homework based on their practical experiment. 

Do Your Research 

It’s of course critical that you know exactly what you are doing before you show your students, but it’s also as important to know your students. For example, if an experiment is more tailored for younger students, do not try it for older kids.  You may also like: 1st grade science project ideas .

The Bottom Line 

And that’s our comprehensive list of the easiest science experiments that you can show students in the classroom, at home, or out in the field! We hope you have enjoyed our guide and you’ve found some amazing new experiments for your students! Good luck.

Top tip: Teach your students about the most famous inventors while they work on their own science experiments.
