15 Science Experiments You Can Do In 15 Minutes

March 20, 2020 by Selena Robinson Leave a Comment

Try one of these easy 15 minute science lesson!

There’s nothing that keeps kids interested in learning like a great science experiment!

But if a science activity requires a lot of supplies or if it takes a super long time to show results, it can be tough to keep the kids interested long enough to observe it all the way through.

Plus, who has time or space to work on a science experiment for days on end?

And that’s why I love these easy 15 minute science experiments!

These activities are simple, quick, and educational – perfect for learning at home or in small groups!

Simple Science Experiments: Simple Light Refraction Experiment

December 28, 2017 by Selena Robinson 9 Comments

This simple light refraction experiment for kids is an awesome way to learn about the properties of light!
Simple Light Refraction Experiment - Look! We're Learning!

We’re continuing with our simple science experiments this week by taking a look at light refraction. I found a great light refraction experiment video on YouTube and decided to try it with Tigger.

Full disclosure: I didn’t know that refraction was what this experiment demonstrated. I actually had to look it up first. But the experiment is super easy and quick, so that’s a big plus!

And, if you like this one, try some of our other science activities, including how to make an egg float and our easy heat conduction experiment!

Study the properties of light with this simple light refraction experiment!

Simple Light Refraction Experiment

Watching the original light refraction experiment on YouTube will give you a great look at what’s involved in this activity. But you really only need four things:

  • A sticky note (I used a Post-It)
  • A marker
  • An empty transparent bottle
  • Water

Experiment on Refraction of Light

Draw two arrows on a sticky note. Make sure that each arrow points in a different direction. Stick the note to a blank wall.

Next, fill up the water bottle. Oh – put the lid on before you do this too! You don’t want water spilling out when you move the bottle around…lol.

Simple Refraction Experiment

The alternating arrows on the note point to the left and the right. Let the kids gradually move the water-filled bottle in front of the sticky note. As the bottle moves in front of the sticky note, something amazing happens.

Investigating Light Refraction

The arrows appear to change direction! The top arrow, which points to the left, appears to point to the right. And the bottom arrow, which points to the right, appears to point to the left!

Simple Light Experiment

Move the bottle back to see the arrows return to their original directions.

So what exactly is going on? We learned that refraction occurs because light bends when it passes through substances, such as water and plastic.

As the light travels through a substance, it becomes concentrated into a focal point, usually near the center. After light passes through the focal point, the rays cross over each other and cause images to appear reversed.

Turns out you can’t believe your eyes after all! 🙂
