Water Cycle STEM Activities: Hands-On Learning for Elementary Students

Dive into the fascinating world of water cycle STEM activities! These hands-on learning experiences will engage your elementary students in science, problem-solving, critical thinking, and creativity, as they explore the wonders of Earth science.

In this blog post, we’ll take a look at some engaging water cycle STEM activities that you can implement in your toy brand, training institutions, children’s activity organizations, distributors, wholesalers, or as a gift and toy importer.

1. Rain Cloud in a Jar


  • Clear jar or large glass
  • Shaving cream
  • Food coloring
  • Water
  • Dropper


  1. Fill the jar or glass about ¾ with water.
  2. Create a “cloud” by adding a layer of shaving cream on top of the water.
  3. Let the students choose their favorite food coloring and use the dropper to add drops onto the shaving cream.
  4. Observe as the food coloring travels through the shaving cream and starts “raining” into the water below.

This activity teaches students about precipitation and allows them to observe how clouds release water when they become too heavy.

2. Make Your Own Water Filter


  • 2-liter plastic bottles (cut in half)
  • Sand
  • Gravel
  • Activated charcoal
  • Coffee filters
  • Dirty water (can be made by mixing water, soil, and food coloring)


  1. In the top half of the plastic bottle, place a coffee filter.
  2. Add a layer of activated charcoal, followed by a layer of sand, and finally a layer of gravel.
  3. Place the top half of the bottle (with the filter) upside down into the bottom half.
  4. Pour the dirty water through the filter and watch as the water gets cleaner as it passes through the layers.

This activity demonstrates filtration and teaches students about the importance of clean water and the process of water purification.

3. Create a Mini Water Cycle


  • Clear plastic container with a lid
  • Small rocks or gravel
  • Soil
  • Small plant (optional)
  • Water


  1. Create a “land” inside the plastic container by adding a layer of rocks or gravel and a layer of soil.
  2. If desired, add a small plant into the soil.
  3. Add water to the container until it covers about half of the rocks/gravel layer.
  4. Close the container with the lid and place it in a sunny location.
  5. Observe the mini water cycle over time, as water evaporates, condenses on the container’s walls, and then falls back down as precipitation.

This hands-on activity helps students understand the water cycle and its different stages, such as evaporation, condensation, and precipitation.

In conclusion, these water cycle STEM activities offer elementary students an engaging and hands-on approach to learning about Earth science. Incorporating these activities into your offerings will not only provide an enriching experience for the children but also enhance your brand’s appeal to your target customer groups.
