3 Air and Water Experiments That Your Students Will Love

When it comes to science units, nothing is better than reinforcing concepts with engaging air and water experiments! That’s why I wanted to share a few experiments you could use with your air and water in the environment unit. These science experiments require limited materials and can be completed in just a few steps, so you don’t have to worry about using hours of prep!

Air and Water Experiment 1: States of Water

For this air and water in the environment experiment, you’ll need a kettle and water. Be sure to put your mirror in the freezer, so it’s nice and chilly for this experiment.

Then, you’ll want to follow these steps:

  1. Add water to the kettle and let it boil. Steam will start to come out of the kettle as the water boils. Ask students to notice what is happening.
  2. As the water is boiling, hold the mirror above the steam. The water will turn back into droplets once it hits the cold, frozen mirror.
  3. Discuss with students what is happening. Then, make the connection between this experiment and the water cycle. As water sources are heated, it evaporates into the sky. Because the atmosphere is much colder, that evaporation turns back into water droplets – which eventually become rain or snow.
This air and water experiment is great for showing the 3 states of water. You can see the vapour in the kettle, and then you can see it turn back to water droplets on a frozen mirror!

Air and Water Experiment 2: Water Usage

This experiment is great for investigating water usage and pairs perfectly with your air and water in the environment unit. A leaky faucet might seem like it’s not using a lot of water, but this experiment offers a different perspective. During this experiment, I like to discuss the idea of water waste with students and brainstorm ways to save water, such as turning off the faucet when you brush your teeth.

For this experiment, you’ll need access to a sink for this experiment and a cup.

Here are the instructions for this lab –

  1. Tell students that you’ll be letting the faucet leak for a few minutes into the cup. Ask students to make an estimate of how much water they think will be collected. These guesses can be rough, like half a cup or three centimeters.
  2. Then, turn the faucet on, so it is slowly leaking (a few drops per minute). Let it run for the designated time frame you set. Make sure the cup is catching the water.
  3. When the time is up, measure how much water was in the cup and have students compare this to their estimation. You can discuss if it was more or less water than they estimated.
Leaky faucets can waste a lot more water than you'd think. This experiment is perfect for highlighting water wastage and fits perfectly with your air and water in the environment unit!

Air and Water Experiment 3: Air Takes Up Space

It’s hard to visually understand that air consumes space since you can’t see it! This experiment serves as a visual representation of this concept during your air and water in the environment unit. For this experiment, you’ll need a bucket with water, paper, and a cup.

Then, follow these steps to complete the experiment –

  1. Take your piece of paper and crumple it into a ball. Then, stuff the paper into the cup.
  2. Next, slowly put the cup in the water with the opening of the cup facing down. Submerge the cup all the way to the bottom of the bucket. Ask students what they think will happen when you pull the cup back out.
  3. Then, slowly remove the cup from the bucket. Show students that the paper inside the cup is dry. Then, discuss how that is possible! Explain how air takes up space in the cup, even when the cup is put in the water!
This experiment shows that air takes up space! Surprise your students by showing them that the crumpled paper will stay dry even when it is put in the water. This is a fun experiment for your air and water science unit!
