Fifth graders create a cloud jar so that they can observe that clouds are made of tiny droplets of water. After observing the cloud jar, they record their observations on a worksheet in written form explaining that clouds are made of...

First graders make ice cream and determine what makes this liquid turn into a solid.

Students interpret aerial photographs. They view aerial photographs or satellite-produced images to locate and identify physical and human features. They study satellite images and label their images for bodies of water, clouds,...

Can you crush a soda pop can with your bare hands? Try this experiment where with the help of air pressure you can show your friends what kind of strength you have. Make sure you stay safe! There is a video included.

Students describe and create an experiment to indicate that a cloud will form under specific conditions.

Science experiment that simulates how clouds are formed. Includes full list of materials, procedures, and scientific explanation of what must happen in the atmosphere for cloud formation to occur.

For this experiment, students work to find the dew point temperature in their classroom, or the temperature at which water would condense. Includes questions for students to respond to online. Requires free registration in order to save...

For this science activity, students investigate the water cycle by testing the water evaporated from leaves (transpiration). They investigate concepts of evaporation and the movement of water through the different states of the water...

Discover the ins and outs of the water cycle through this collection of experiments and activities.

This ZOOMSci video segment shows how to create self-contained environments and explore how plants grow under different conditions. [3:24]

An experiment that demonstrates why there are clouds in the sky. Start with air, invisible water vapor, particles we call condensation nuclei, and air pressure...the cloud comes later!

In this investigation, students will observe and learn about the different types of clouds and be able to explain in their own words how clouds are formed. They will also observe an experiment illustrating how clouds form.

This is a hands applied lesson plan to help middle schoolers experience the water cycle on a smaller scale. Because of the hands-on nature of the lesson, it works well to help students with a language barrier understand complicated...

In this experiment, you'll make your own cloud in a jar, and get to test the conditions that are required to make a cloud form.

Can you make it rain without doing a dance? Follow the steps in this science experiment to try it!

In this hands-on activity, students experiment to discover how moisture, pressure, temperature, and condensation nuclei play a role in cloud formation.
