Groundwater Experiment

We performed a groundwater experiment to understand aquifers, saturation, and the water table. We are continuing our study of the hydrosphere by using the book Earth and Space by Bright Ideas Press. We are enjoying all the hands-on activities and experiments. Today we will give you a demonstration of this groundwater experiment. But first, we filled out a diagram of the water table, provided in the book.


The rain falls on the ground, and the water sinks into the ground through infiltration. The rock that is permeable allows water to pass through it, while the ground that does not allow water to pass through it is called impermeable rock. The water table is the invisible line that is just above the level of saturation. Of course, saturation means that the ground is holding as much water as it can hold.


When we do the groundwater experiment, you will see that we fill one jar with a thin layers of pebbles and thick layers of sand. The other jar contains thick layers of pebbles and thin layers of sand. Both jars are aquifers: layers of rocks and sand that contain water. Which jar has more permeable ground than the other? Will the water sink through faster through the pebbles or through the sand? Watch the video to find out!

Water Unit Study

When you are doing a water unit study, you will want to observe water in its 3 states: solid, liquid, and gas. We are continuing our study of Earth and Space by Bright Ideas Press, and we are doing the chapters on the hydrosphere.

First we colored and labeled the Water Cycle page provided in the book. Then we dramatized the water cycle by having the kids evaporate themselves up to the chair, puff themselves out as clouds, and rain down by jumping off the chair.

Oceans cover the majority of our Earth, and these currents flow in a clockwise pattern in the Northern Hemisphere, and a counter-clockwise pattern in the Southern Hemisphere. The book says to draw a clock with chalk on your driveway, but since we had snow on our driveway, we decided to use masking tape on the carpet. My daughter demonstrated the ocean currents in our video.


We enjoyed looking at other picture books about water, seeing how it evaporates into the air when you leave a glass of water on the counter. I especially love picture books that have gorgeous illustrations to help kids visualize how important water is to us as human beings.


Most of the fresh water on Earth is found in glaciers. We performed the glacier experiment in the book, where you race two blocks of ice down a ramp, to see if ice with dirt goes faster or slower than ice without dirt. Make sure you use paper cups for freezing your water. The water freezes faster if you used crushed ice from a blender to start with, and the dirt mixes better with the water when you have crushed ice. You’ll have to watch the video to see which glacier wins!
