Sixth graders identify and use area formulas for finding the area of geometric shapes.

Students examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.

Students observe chemical reactions using post-1982 pennies. They observe the reaction of an acid with zinc but not copper under the same conditions over a two week period.

Students recognize that a man's actions in changing his environment can have drastic results for their world. They discuss the use of energy conservation and the use of recycling materials to improve our environment.

Students explore the concept of sea ice. In this sea ice lesson, students interview arctic hunters to regarding the sea ice safety and attributes.

Students investigate road surface and calculate speed. In this algebra lesson, students analyze the roughness of a road and calculate distance and speed based on friction. They relate friction and energy to speed.

Students explore the DNA of strawberries. In this science instructional activity, students extract the DNA of strawberries. Students complete a lab report.

Students investigate how particle size affects the angle of a volcano's slope.

Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

Tenth graders study the metric system.  In this metric lesson students complete a lab activity and several metric worksheets. 

Students study a topic of an environmental nature that is relevant to them (as individuals) on a local level, but with global implications. They consider whether their family's shopping habits have any lasting effects on the environment.

Students demonstrate that light and dark colored objects absorb the sun's radiation at different rates. They experiment with the temperature change of water in two locations and discuss the results.

Young scholars make and test hypotheses about atmospheric data collected aboard the NOAA ship Ronald H. Brown research cruise.

Students identify fire risk factors for a property located near a wildland area. Students discuss ecosystems subject to wildland fire and consider what could be done to eliminate the problem.

High schoolers discover how and why the settling rate of particles differs with the size of the particles. Using different soil samples, they calculate the amount of time it takes for a sample to settle in water for up to forty minutes....

Students engage in a study of financial institutions that includes the banking industry. They participate in a research study using different resources. They are introduced to the concept of bartering and how it is used as a replacement...

Students participate in a class discussion about Bernoulli's principle while looking at cross-sections of an airplane wing, and discussing the sail on a sailboat and the spoiler on a race car.

Learners define kinetic energy and know the effects of weight and speed on momentum.  In this investigative lesson students get into groups and design a roller coaster. 

Students define potential and kinetic energy and explain the relationship of height to potential energy.  In this roller coaster lesson students construct a model of a roller coaster which will allow them to see the basic physical...

Learners examine the amount of radon in their home. They discover how it enters the home and how to properly seal off any route that is allowing radon to seep in. They calculate the amount of ventilation needed in their home to be safe.

Learners study the growth and care of plants. They take tour of their school site and plant seeds to observe their growth. Afterward, they answer questions about the origin and value of their plants.

Practice your estimation skills by comparing the number of objects shown, the length of a curve or the area of a shape to a given number. Your choices are "greater than" or "less than".

This activity allows the user to practice estimation skills by determining if a given amount is more or less than the number of objects shown, the length of a curve, or the area of a shape. An interactive activity and teacher resources...

An in-depth guide for educators about Informed Assessment Practices. These types of practices can efficiently shed light on student learning; without them, educators cannot determine the most appropriate next steps to strengthen...
