Water Cycle Bag Experiment

This Water Cycle Bag Experiment is a great way to introduce them to science and all the ideas of the water cycle.

If you love this experiment, check out these fantastic weather activities for kids.

It is a pretty cool fact that water is the only substance that appears naturally in all three states of matter: solid, liquid, and gas. The solid form is ice or snow, the liquid is rain or condensation, and the gas is vapor.

I love that you can experiment with things you have on hand and at home and keep watching the cycle as long as the kids stay interested. We still have one hanging in a window now.

Isn’t it amazing how many fun science activities and experiments can be done right at home? With just a few simple supplies, this water cycle experiment can happen!

It’s perfect for hands-on learning and a great way to get the kids involved.

Water Cycle Bag Experiment

The great part about doing this Water Cycle Bag Experiment is that it really does teach the kids about the water cycle in a fun and cool way. Anything hands-on is always a good idea!

What happens in the water cycle?

The water is heated by the sun and turns into a gas (evaporation) when it hits the sides of the bag and cools it becomes solid water again( condensation). As the water drops grow larger and heavier they begin to fall back down into the bag (rain).

Then the cycle begins all over again.
One fact to point out to your children is that the droplets on the side of the bag are clear, not blue.

When the water evaporates the blue food coloring is left behind.

Water Cycle in a Bag Experiment Supplies

All you’ll need to get started on this simple science activity is listed below.

• A quart zip-top bag
• Water
• Tape
• Permanent marker
• Optional- blue food coloring

    

 

Directions

1. To make it a bit more fun and to help children understand the process better the first thing you want to do is draw land/water and the sun on your bag using a permanent marker. Make a clear water line.
2. Next, fill the bag with water just to the water line, and add blue food coloring if you wish, again this gives the impression of water and helps kids see the process a bit better.
3. Seal your bag well and tape off the top.
4. Find a sunny window in the house to hang your bag in, be sure it is secure.

You can explain to your children and then let them experience it by watching what happens in the bag and comparing it to watching the real water cycle at work.

When water absorbs and releases energy from the heat it changes into different states of matter. The first thing you will notice in your bag is that after a while in the sun droplets begins to form inside the walls.

Did you like this water cycle in a bag activity? Talk to the kids about their thoughts and what happened. This is a great chance to dive deeper into the topic and find out more as well. You can then create a few follow-up questions to talk about and make a plan for there to learn even more.

Why are STEM experiments important for kids?

STEM is such a great hands-on resource. The more that they are interested in ideas and activities, the more that they’re going to want to keep doing experiments.

Kids are more apt to have fun with learning when there ar fun experiments involved. Why not give a few a try and see what the kids like?

They may find a new activity that they never knew they liked!
