Students investigate potential energy held within springs (elastic potential energy) as part of the Research and Revise step. Class begins with a video of spring shoes or bungee jumping. Then students move on into notes and problems as a group. A few questions are given as homework. The Test Your Mettle section concludes. The lesson includes a dry lab that involves pogo sticks to solidify the concepts of spring potential energy, kinetic energy and gravitational energy, as well as conservation of energy.

This video segment from 'Earth: The Operators' Manual' explores how we know that today's increased levels of CO2 are caused by humans burning fossil fuels and not by some natural process, such as volcanic out-gassing. Climate scientist Richard Alley provides a detailed step-by-step explanation that examines the physics and chemistry of different "flavors," or isotopes, of carbon in Earth's atmosphere.

This lesson introduces students to three of the six simple machines used by many engineers. These machines include the inclined plane, the wedge and the screw. In general, engineers use the inclined plane to lift heavy loads, the wedge to cut materials apart, and the screw to convert rotational motion into linear movement. Furthermore, the mechanical advantage describes how easily each machine can do work and is determined by its physical dimensions.
Kahoot's game-based pedagogy empowers learners to present and share their new-found knowledge …
Kahoot's game-based pedagogy empowers learners to present and share their new-found knowledge to their peers, so they can go from ""learner to leader"". Students in any grade or subject matter may play this game. Students are able to compete with each other through a leader board system while engaging students in the learning process. Educators may design their own games or may borrow an already create game through the public Kahoots.

This is a National Geographic short video that briefly describes how succulent plants in the South African Karoo biome are dying off due to changes in climate.
Student teams design insulated beverage bottles with the challenge to test them …
Student teams design insulated beverage bottles with the challenge to test them to determine which materials (and material thicknesses) work best at insulating hot water to keep it warm for as long as possible. Students test and compare their designs in still air and under a stream of moving air from a house fan.

Through two lessons and five activities, students explore the structure and function of cell membranes. Specific transport functions, including active and passive transport, are presented. In the legacy cycle tradition, students are motivated with a Grand Challenge question. As they study the ingress and egress of particles through membranes, students learn about quantum dots and biotechnology through the concept of intracellular engineering.

Students learn how roadways are designed and constructed, and discuss the advantages and limitations of the current roadway construction process. They look at current practices of roadway monitoring, discuss the limitations, and consider ways to further road monitoring research. To conclude, student groups compete to design smooth, cost-efficient and sound model road bases using gravel, sand, water and rubber (representing asphalt). This lesson prepares students for the associated activity in which they act as civil engineers hired by USDOT to research through their own model experimentation how to best use piezoelectric materials to detect road damage by showing how piezoelectric transducers can indicate road damage.

Dense populations of some microscopic algae (phytoplankton) in ocean waters can contaminate seafood, resulting in serious health problems for humans. Satellite data displayed in an online tool help fishermen monitor and avoid these harmful algal blooms.

This activity identifies and explains the benefits of and threats to coral reef systems. Students read tutorials, describe the role of satellites, analyze oceanographic data and identify actions that can be undertaken to reduce or eliminate threats to coral reefs. As a culminating activity, students prepare a public education program.

This video segment highlights how the U.S. military is the single largest user of energy in the nation, but it is also trying to reduce its carbon bootprint. Scenes taped at Fort Irwin and Camp Pendleton show the Army and Marines experimenting with wind and solar in order to reduce the number of fuel convoys that are vulnerable to attack.

Students learn how crystallization and inhibition occur by examining calcium oxalate crystals with and without inhibitors that are capable of altering crystallization. Kidney stones are composed of calcium oxalate crystals, and engineers and doctors experiment with these crystals to determine how growth is affected when a potential drug is introduced. Students play the role of engineers by trying to determine which inhibitor would be the best for blocking crystallization.
