Where did the water go? Learners conduct an experiment to see how the difference in temperature affects evaporation rates. Scholars continue to investigate evaporation by comparing water and alcohol evaporation rates. Pupils experiment...

One way to study something is to try to replicate it. Young scientists do just that as they use solutions to recreate mineral structures on a dwarf planet. They make solutions with different types of salt, evaporate them, and observe the...

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

Where does the water come from? Pupils conduct an experiment to learn more about condensation. Scholars fill two cups with ice water and isolate one from the surrounding air. They then use a coffee filter to compare the amount of water...

How do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

Explore the sun's ability to distill contaminated water with this simple set of classroom experiments. After filling two glass bowls, one with muddy water and the other with salt water, they are covered with plastic wrap and placed...

Let knowledge of chemistry flow like water. Future scientists conduct two different experiments to investigate the properties of water. They learn about surface tension and cohesion as they see how many drops of water they can place on a...

This resource provides a short experiment for students to explore how clouds are formed.

Don't let your bacteria go to waste. A tutorial explains how to properly store and maintain bacterial stock cultures. It describes the purpose and preparation of a permanent stock, as well as a working stock for use in experiments.

Of quartz I love geology! The chapter offers five activities at three different levels. It features hands-on activities that cover crystal shapes, cleavage and fracture, hardness scale, specific gravity, and mineral...

A lab experiment where students try to increase the rate of evaporation by adding heat to the water. Students will experience the process the evaporation with this activity.

This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out...

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.

With this science fair project measure the effect of wind speed on how quickly an object cools. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on...

When you are craving an ice cold drink of soda, the last thing you want is to be stuck with a bunch of soda cans at room temperature. This fun science experiment sends you on a discovery to find the fastest way to cool soda with...

Create your own Olympic medal out of clay with the help of an adult. Watch as your design hardens over time as the water in the clay evaporates.

In this activity, Students can use temperature sensors to compare the heating rates of wet sand and dry sand. They will use the results of the experiment to understand more about the effects of evaporation.

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.

Conduct an experiment and investigate how air temperature, relative humidity, wind speed, solar radiation and precipitation affect evaporation. Graph the data collected during the experiment.

Try this at-home science experiment to learn how warm water (sweat) makes us feel cooler.
