Students comprehend that ratios and fractions are interchangeable. They compare ratios using common denominators, cross multiplication, and intuition. Students find equivalent fractions. They comprehend that equivalent ratios do not...

Students investigate water usage at school and at home. They use graphs and tables to evaluate water usage. Students describe possible water conservation measures. They use graphs and tables to relate data as part of a written report.

Students describe stellar objects using terms such as stars, planets, satellites, orbits and light. In this sun and stars unit, students research stellar objects through seven individual lessons discovering star characteristics, how...

Students explore measuring with a graduated cylinder. In this measurement lesson, students observe liquids in a beaker. Students predict the volume of liquid in the beaker and then transfer the liquid to a graduated cylinder. Students...

Double click that mouse because you just found an amazing lesson! This cross-curricular Ornithology lesson incorporates literature, writing, reading informational text, data collection, scientific inquiry, Internet research, art, and...

Students determine sea ice thickness, concentration, and floe size by reading egg codes.  In this sea ice conditions lesson, students color code a map based on prescribed criteria and use the maps to identify changes in sea ice...

Students design and build a snowplow using LEGO materials. They compete in an Engineer's Challenge to clear a path through Styrofoam peanuts.

Students examine that all living things depend on soil to live. In this science activity, students pretend that an apple is planet Earth. Students cut the apple to represent the portions of Earth with the last section representing soil.

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 study the egg code to learn about sea ice. In this sea ice activity, students discuss and view a diagram to learn about the egg code when describing sea ice and its thickness. Students work in groups to play a game using the egg...

Learners work collaboratively to gain a better understanding of the vastness of space by scaling down the solar system. They measure by inches, gain an understanding of space, and model the distances of the planets from the sun.

Students examine the diet of panthers. In this interpreting data lesson, students collect data on the panther's diet and chart the data in bar and pie graphs.

Seventh graders simulate the capture-recapture method of population sampling using beans. In this biology lesson, 7th graders calculate the total population of beans in the bowl. They assess whether this method is reliable or not.

Students observe and discuss cloud cover. They identify percent of cloud cover, calculate cloud cover by fraction and convert to a percent, and compare their models with the current real sky cloud cover.

Pupils begin the lesson by noting the many ways in which to use peanuts. In groups, they use the internet to research the work of George Washington Carver. They discover the allergies and nutritional information of the peanut and examine...

In this interactive lesson, students will experience the engineering design process as an aerospace engineer assigned to design and test an airplane.
