Young scholars observe the changes a class tree goes through as the seasons change and record observations in journals. They investigate changes in the weather, changes in the length of the day, and how that affects people. They create...

Students use their senses to investigate the changes in the seasons. They discuss how the Earth moves around the sun and its tilt. They practice using new vocabulary and examining the different seasons.

For this complex game about the carbon cycle, the playing field is divided into air, living, and earth zones. Children are assigned to be either plants or animals, and collect carbon tokens as they proceed from zone to zone. While the...

After reading a brief history of Carl Skalak's journey on the open waters, scholars make a three-dimensional model of the Earth out of an Origami balloon using a printable decorated as the Earth.

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

Installment eight of the 10-part Discover Your Changing World series tests the class's understanding of climate. Scholars play alone or in small groups to assess their understanding of climate systems, causes of climate...

In this earth's seasons worksheet, students answer fill in the blank questions after seeing Bill Nye's video. Topics include the rotation of the earth around the sun, the tilt of the earth, the time zones and sunlight.

In this Earth Science worksheet, students read about the Greenhouse Effect and the difference between natural and amplified warming. Following, they answer ten short answer questions related to what they read about global climate issues.

Students explore how to describe the Gulf Stream, how Benjamin Franklin charted it, and correctly plot it on a map.

Investigate the water cycle and how water moves from the land to the air and back to the land. Create a terrarium and observe the water cycle at work. Define weather terms including evaporation, condensation, and precipitation.

Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

It is colorless and scentless, but it makes a large impact on the environment. Learners explore carbon dioxide emissions and what they mean for the environment using an interactive graph. They review changes over time and how they impact...

Students make a striking visual display showing the distribution of water on earth.

Students explore the relationship between the amount of water in the atmosphere available for precipitation and the actual precipitation observed by satellite. They examine seasonal changes in precipitation. They practice using Internet...

Students study the water cycle and create a booklet entitled: "Discover the Wonder of Water" They observe and record data regarding evaporation, condensation, and precipitation and how water moves from a solid to a liquid to a gas. They...

Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.

Discuss different sources of energy and how much greenhouse gas each might emit. The six sources are then ranked according to emissions from greatest to least. Finally, the true cumulative emissions are revealed to show the class how...

Here is a very basic look at the moon and its positioning around our planet. The pictures and labels here show different phases and will help your space explorers understand our changing views of the moon along with the Earth's tilt and...

Teams of six to eight players imagine that they are driving in a vehicle and collect balls that represent carbon dioxide emissions based on their different activities. "Greenhouse Gas Guzzler" cards tell teams how many balls to collect...

Writing a persuasive argument starts with a clear thesis. Using this resource, your class will write a persuasive paper on a conservation issue. They will then transform their argument into a 30-second public service announcement. If...

Third graders relate that the quality of their drinking water is subject to the condition of the environment and water found in streams and creeks in their community. They track the travel of a wad of paper from a student's desk to a...

Learners examine the relationship between chlorophyll and carbon dioxide in the atmosphere.  In this investigative lesson students study the local effects of climate change. 

Students listen to story, The Lorax, by Dr. Seuss, discuss air quality and how people affect the earth and its atmospheric cycles, and give oral reports on what they have learned.

What can shadows tell us about the changing season? Over several months, astronomy learners record length and position of an outdoor object's shadow, such as a flagpole. They apply the data to a growing hypothesis and note the...
