Science Experiments For Kids: Teach Your Children How Water Cycle Works

Science Experiments for Kids not only gives your children a cool activity to do, but it also educates your children if it’s done right.

Summer is almost here, which means your kids will be in the house far more often and more restless than ever. Although the coronavirus pandemic may be just about over (fingers crossed) by the time school officially ends, your children will still be in the house for prolonged periods of time during the summer.

Rather than letting them rot their brains with video games and television, try introducing them to fun science experiments for kids and other educational activities. There are a variety of experiments you can introduce to your kids and have them run during the day. Science experiment for kids can be fun, it doesn’t have to be all multiple-choice questions and stuffy procedures, there is plenty of exciting and surprising natural phenomenon and other scientific principles you can introduce your kids to during the summer, keeping your brain and theirs wired during the doldrums of the season.

Your kids will be delighted by what they learn when you run experiments and they’ll be instilled with the knowledge that they’ll carry with them into future grades and beyond. One of the most fun and educational experiments you can your kids run pertains to the water cycle. The water cycle is an incredibly important concept for kids to learn and it’s actually quite easy to teach during a lazy day. A popular way to teach your children about the water cycle, or reinforce their knowledge if they’ve already been taught, is with a bag and some water.

The Set-Up

More specifically, the tools you’ll need for the science experiments for kids: a gallon-sized plastic bag, some water, food coloring, a marker that won’t wash off easily, some packing tape, and a sunny day.

You’ll begin the experiment by drawing a model of the water cycle on the outside of the baggy you’ll be using. This is a visual aid for your kids to know and remember the parts of the cycle and which parts are which why the experiment is running.

Next, you’ll want to fill the bag up with just a few drops of water then add your food coloring to the water. The food coloring makes the water more visible to the naked eye and will help reinforce the concepts later down the road.

After, seal the bag, and seal it tight. You’ll want to take the bag to a sunny window with a strip of your packing tape. Make sure the bag is tightly sealed and tightly taped to the window, so no messes are made.

The most natural and wonder-filled way to run the experiment is to wait for a sunny day to come by, which shouldn’t be much of an ask during the summer. However, if you’re antsy to run the experiment or the sun just refuses to come out from the clouds, you can use a hairdryer set to its lowest setting, so as to not melt the bag.

Science Experiments For Kids: The Science

As time goes by, the plastic bag will eliminate any escape of the evaporating water in the bag. Thus, the three phases of the water cycle will take place before your kids’ very eyes, in an observable and actionable way. When the sun warms the bag, some of the water inside the bag will evaporate although, again, it cannot escape. The water will rise above the water level, which in turn will increase the humidity inside the bag.

As the humidity slowly and inevitably increases, the air in the bag will become saturated and filled with moisture. This saturation will slowly cause the water vapor in the bag to condense and turn the water vapor into thicker, heartier drops of water. The water will then collect on the side of the bag and roll down the bag, representing precipitation. This is the entire water cycle in a nutshell, seen obviously and quickly before your and your kids’ very eyes.

I hope you enjoy our science experiments for kids. There will be more science experiments for kids coming out soon, and let us know which one was your favorite!
