Students examine how the processes of condensation and evaporation occur. They describe the relationship between heat energy, evaporation and condensation of water on Earth. They give examples of the processes of evaporation and...

Students complete activities to study decomposition. In this decomposition instructional activity, students work in pairs to observe a decay buffet experiment. Students keep compost bag journals. Students define and discuss the process...

Learners study weather using a graphing calculator in this lesson. They collect data for temperature and relative humidity for every hour over a day from the newspaper, then place the data in their handheld calculator and examine it for...

Middle schoolers observe weather conditions of a particular city. Multiple intelligences are explored within this instructional activity. They locate their particular city on a United States map. Each student writes about their...

Using a digital camera to document local landscapes as they are today, students will explore how changes in human land use are impacting local environments. Students will also explore some of the social impacts of various land uses in...

Students conduct an experiment in which they bury four objects (apple, lettuce, plastic and styrofoam) in the ground and come back to observe them a month later. They consider what biodegrades and how it affects our planet.

Students design a calendar that displays time on Mars. They explore the differences between time on Earth and time on Mars while making the calendar.

Eighth graders describe the steps in the water cycle. They discuss factors that affect runoff and explain the differences between stalactites and stalagmites. They discover the importance of ground water.

Learners observe and classify the permeability of a variety of materials.

Fourth graders explore and discuss the process of evaporation. They discuss how wet things become dry. Students observe the process of evaporation and they make predictions about the observations they make about evaporation. Students...

Students explore features to consider when designing a scientific study. In this science research lesson, students examine different methods of data collection and consider which method would be appropriate for determining how many types...

Scholars independently explore several websites to calculate their ecological footprint. Using their new found knowledge, they answer six short-answer questions and take part in a grand conversation with their peers about how...

Using the NASA website, class members try to determine if changes could be detected in cloud cover, temperature, and/or radiation measurements due to the lack of contrails that resulted from the halt in air traffic after the attacks...

Students explain why compass angles need to be corrected for regional magnetic variation. They observe the difference between magnetic and true north. Each student measures the angle of variation for a town in a different state.

Students investigate the greenhouse effect and examine the potential effects of climate change in the Arctic. They construct a mini-greenhouse and test its effect on temperature, analyze historical climate statistics, and conduct an...

Be sure to come prepared to discuss the theory of Pangaea and the two super-continents, Laurasia and Gondwanaland. Collaborative learners look for fossil evidence that supports the theory that one super-continent divided into two. They...

You'll have oodles of Google Doodles. Scholars create their own Google logos using the Scratch coding program. After watching videos on how to add blocks of code in Scratch, they use their newfound knowledge to design a logo based on a...

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...

Tenth graders use a classification key to identify organisms.  In this classification lesson students identify freshwater species of fish and document their observations. 

Middle or high schoolers transform into oceanographers in a week-long simulation. To begin, each group follows directions to create a model of the ocean floor with specified features. Next, the groups prepare to set sail on a research...

Students discover how worms contribute to the balance of the environment. In this composting lesson, students study the composting and decomposition processes. Students then create habitats for worms that allow them to do their jobs.

Understand how chemical reactions recombine atoms to create the "chemicals of life". An experiment, showing the basic chemical reactions of an iron nail or a match, helps young children start their understanding of permanent changes.

A great way to recall the parts of a flower is to make one. Little learners create sunflowers out of paint and paper plates. They also discuss and label the various parts of their flowers. 

Who doesn't love a rainbow? Little ones adore them, so why not make rainbows the subject of your next art project. Your class can use watercolor to paint rainbows. As they do, have them identify the colors in the rainbow, talk about how...
