Students observe and sort tree leaves. In this earth science lesson, students observe the attributes of real leaves and measure leaves using Unifix cubes.

Students investigate soil temperatures. In this graphing and earth science lesson, students insert temperature probes into different types of soil at varying depths. Students complete a data chart and construct a related graph...

Students create scale models of Earth, the Moon, and the distances within the universe. Working in groups, they construct their models of Earth and the Moon on a scale of 50:1 and calculate how far apart to place their models. They...

Students calculate the radius of the earth. They use the method and data suggested by Eratosthenes. They investigate the interrelationships among mass, distance, force, and time through experimental processes.

Pupils use scientific tools. In this Applied Science lesson, students investigate the use of scientific tools to enhance observation and discovery. Pupils indicate how each tool assists scientific work.

Sixth graders identify and describe the composition and physical properties of the layers of the Earth. They also explain how scientists used the scientific process to know about the center of the Earth. Finally, 6th graders read a...

High schoolers complete a lab that introduce the scientific concept of climate on Earth. Following the lab, they complete further research on climate. Using average monthly temperatures students construct a mathematical model and analyze...

Students study the amount of potable water on the Earth. In this water instructional activity, students examine the amount of potable water as compared to all the water on the Earth. They discuss why many parts of the world do not have...

Students examine and calculate the percentage of potable water remaining on the earth. For this ecology and geography lesson, students brainstorm the main factors affecting water distribution. Students use mathematical problem solving to...

Students explore space science by completing a worksheet in class. In this astronomy lesson plan, students discuss and identify star patterns in the night sky and relate these patterns to the approximate time they appear. Students...

Students examine and study how changes in perspective can change the way that they can observe objects. They explore the relationship between a scene's area and its detail. Each student looks at the ground through cardboard tubes from...

Students construct their own water filter to obtain clean water. In this filtration instructional activity, students produce tainted water in order to properly filter it with filtration devices made in class.

Students gain an understanding of how the powers of 10 and scientific notation can be used to represent the scale of things in the universe. They relate the number of stars in the universe to the number of grains of sand on Earth's beaches.

Does it ever seem like time is slipping through your fingers? Model the passing of time with an hourglass activity in which individuals determine whether hourglasses are the most efficient way to measure time.

Students examine and compare traits of humans and crocodiles.  In this crocodile lesson students use a ratio to estimate the height of a person and compare that to a crocodile. 

Students identify the different factors affecting the size and shape of ocean waves. In this math lesson, students calculate wave speed and wavelength given a mathematical formula.

How has the level of carbon dioxide changed over recent years, and what is contributing it? Groups work together to research and present their findings in a creative way. Also built into the instructional activity is a visit to a...

Students examine how Earth's rotation causes daily cycles in solar energy using a microset of satellite data to investigate the Earth's daily radiation budget and locating map locations using latitude and longitude coordinates.

Here's a workshop for teachers that rocks the academic world! Using earthquakes as a medium for instruction, educators learn about crosscutting engineering with science. Fun, hands-on, collaborative exercises encourage participants to...

Investigate the use of ratios in scale drawings. Learners scale objects up or down using ratios then find the actual size of something using ratios. They apply their knowledge of ratios as they make their own telescopes in science...

Students build a solar oven. In this Science lesson, students construct a functional solar oven. Students design the oven and explain the energy concepts involved.

What is the meaning of sea level? This resource helps your class understand the meaning of elevations above, below, and at sea level. Provides for good discussion on using positive and negative numbers to represent quantities in the real...

NASA presents a mini-unit on distances in our solar system. It incorporates scientific concepts of gravity, mass, density, and payload while your aspiring astronauts also employ mathematics skills. They calculate speed, they determine...

The battle of the sexes? Scholars first examine data on hurricane-related deaths and create graphical displays. They then use the data and displays to consider whether hurricanes with female names result in more deaths than hurricanes...
