This easy-to-perform demonstration shows students how the water cycle, specifically the processes of condensation and evaporation, purifies Earth's water supply. Just mix up some water, dirt, and gravel in a glass bowl, place a cup in...

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...

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...

If you have or want to order the dipping bird demonstration, it is useful for showing how evaporation and changes in the pressure of a closed system cause cyclical motion. After teaching about pressure, consider setting this little guy...

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...

Young scientists get their feet wet as they learn about the water cycle in this series of activities. Whether they are observing how evaporation causes puddles to dry up, or how plants put water into the atmosphere through...

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...

To prepare for a performance task assessment, class members review the stages of the water cycle and then individuals assume the roles of drops of water for a Reader's Theater exercise. The script, a graphic depicting the water...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

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...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice...

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...

Transform your classroom into a fully functioning weather station with this series of hands-on investigations. Covering the topics of temperature, precipitation, wind patterns, and cloud formation, these activities engage young...

Bring the water cycle to life with in the classroom. Young scientists use household materials to create and monitor a water cycle model. They record changes in the water levels and make observations of where and how fast precipitation...

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...

Invite your learners to take a close look at Abraham Lincoln's presidency through analysis worksheets of several images and primary documents, presented on an educational poster entirely dedicated to this great United States...

Where does the water we use come from? To understand the concept of a watershed, class members study the water cycle and then engage in an activity that simulates a watershed.

Learners investigate how solar energy is converted into heat in part two of the 10-part Discover Your Changing World series. They build and test homemade solar cookers to boil water and cook rice. Pupils consider the impact of heat...

As part of a unit, this lesson familiarizes youngsters with components of a rain garden. They speculate about the role of an assigned component in contributing to a rain garden, and ultimately, in the health of the local watershed. Each...

Your learners analyze various real-life contexts to decide if each is a linear or exponential model. This could be used as an assessment of learners' skills of discerning between a linear and an exponential model.

Dressing for success is not always about looking sharp. Sometimes it is about staying warm and dry. Present your class with an activity that challenges groups of pupils to design a layered material for blizzard conditions. The teams test...

Into each life some rain must fall, but how can that change rocks? Young geologists' understanding of weathering and erosion increases throughout the activities. The lesson includes five short activities to be completed...

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