Worm Your Way Out of This
How can you provide healthy soil for your garden? Study worms, bacteria, and other microorganisms in a lesson about decomposition and organic compost. After discussing what you know about worms and watching a video, watch what worms do...
Curated OER
Metric Mania
Students observe how to measure in metric units. In this investigative lesson students compare different units of volume to see how things are measured.
Curated OER
Trig River
Students calcute distances using trigonometry and angle measurements. They estimate the width of the Trig River, measure it and compare their results with their classmates. They collaborate with a group to research and find the results.

Making It Balance
Students listen to story, "The 100-Pound Problem," compare their weight with character in story, and weigh different classroom items using nonstandard units and standard units. They experiment with different items that can make scale...
Curated OER
The North (Wall) Star
Students engage in a lesson which shows them that celestial navigation is the art and science of finding one's geographic position by means of astronomical observations, particularly by measuring altitudes of celestial objects - sun,...

TE Activity: The Beat Goes On
Students determine what the pulse is before examining how to measure the heart rate in different situations. They build a simple device that measures the heart rate, take heart rates, and record them on a worksheet. They discuss how...
Curated OER
Earthquakes Rock!
Students study the main methods to measure earthquakes; the Richter Scale and Mercalli Scale. They make a model of a seismograph and investigate which structural designs are most likely to survive an earthquake.
Curated OER
Environment: Wild Wind Direction
Students examine the different types of wind patterns. Using common materials, they construct weather vanes to measure and record wind direction over a two-week period. After analyzing the data, they draw conclusions about the...
Curated OER
Harnessing Wind
Young scholars explore the ways that engineers study and harness the wind. They study the different kinds of winds and how to measure wind direction. In addition, students learn how air pressure creates winds and how engineers build and...
Curated OER
How Do Things Fall?
Students study forces by examining the force of gravitational attraction. They observe how objects fall and measure the force of gravitational attraction upon objects. Students discover that, since gravitational constants are different...
Curated OER
Wind Power
Fourth graders develop an understanding of how engineers use wind to generate electricity. They will build a model anemometer to better understand and measure wind speed. They discover that engineers design wind turbines that generate...

Topo Triangulation
Learners investigate how to read a topographical map and triangulate with just a map. They convert a compass measurement to a protractor measurement, reverse a bearing direction, and using a worksheet take a bearing of certain landmarks...
Curated OER
Intersecting Lines and Vertical Angles
Pupils identify and define intersecting lines and vertical angles. They draw two intersecting lines and measure one pair of vertical angles. Learners will also move a line to change the angles of a figure and describe the changes in the...
Curated OER
Weather Dot Com
Students examine the need for a standard unit of temperature and measure temperature with a thermometer. They discuss the details of a thermometer and the calibrations used, record temperature data for inside and outside, explore...
