Students use a watt meter to measure energy input into a hot plate or hot pot used to heat water. The theoretical amount of energy required to raise the water by the measure temperature change is calculated and compared to the electrical energy input to calculate efficiency.

Students use LEGO® motors and generators to raise washers a measured height. They compare the work done by the motor-generator systems with the energy inputs to calculate efficiency.

A process for technical problem solving is introduced and applied to a fun demonstration. Given the success with the demo, the iterative nature of the process can be illustrated.

The purpose of this activity is to recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and students will perform several velocity calculations. Also, students will have to design and build their lander within a pre-determined budget to help reinforce a real-world design scenario.

The “Einstein Project” is a framework that is designed to help you find a solution to an everyday problem that makes you passionate in your thinking and designing. This project is designed to make you think outside of the box as active learners and create solutions in uncommon ways, forget about failing or succeeding and take chances.

As part of the engineering design process to create testable model heart valves, students learn about the forces at play in the human body to open and close aortic valves. They learn about blood flow forces, elasticity, stress, strain, valve structure and tissue properties, and Young's modulus, including laminar and oscillatory flow, stress vs. strain relationship and how to calculate Young's modulus. They complete some practice problems that use the equations learned in the lesson mathematical functions that relate to the functioning of the human heart. With this understanding, students are ready for the associated activity, during which they research and test materials and incorporate the most suitable to design, build and test their own prototype model heart valves.

SYNOPSIS: In this lesson, students conduct research on electric bicycles and electric cars, choose one of these technologies, and create a video promoting its use as a climate solution.

SCIENTIST NOTES: Over the course of their use, electric cars are far more environmentally friendly than conventional automobiles. This lesson examines those benefits as well as how to make cities friendlier to bikes and other commuting options. The external resources in this lesson have passed our scientific review process.

POSITIVES:
-Students must use hard data to promote either electric bicycles or electric cars.
-Students record quick, informative videos as their assessment in this lesson plan.

ADDITIONAL PREREQUISITES:
-Students should have a basic understanding of climate change. They should know that burning fossil fuels creates greenhouse gases and that greenhouse gases are heating up the planet.
-There are fourteen total images in the Inquire section. Feel free to disregard some of them based on your needs.
-Many students assume that electric cars do not create emissions at all. Students will learn:
-There are embedded emissions from the manufacturing of electric cars.
-Electric cars that use electricity generated by fossil fuels (coal, oil, and gas) are still creating emissions.
-Your students will need access to devices to record their advertisements. Students can record themselves on iPods, iPads, laptops, or other school devices. Depending on your school's phone policy, you can have your students use their own devices.

DIFFERENTIATION:
-Be sensitive to the socioeconomic situation of your students. Some students' families may not own bicycles or cars or be able to afford electric bicycles or electric cars.
-Creating the advertisement can be done as a homework assignment.
-Students may want to include drawings, puppets, props, or other creative items in their advertisements. Encourage their creative expression!

Students are briefly introduced to Maxwell's equations and their significance to phenomena associated with electricity and magnetism. Basic concepts such as current, electricity and field lines are covered and reinforced. Through multiple topics and activities, students see how electricity and magnetism are interrelated.

The grand challenge for this legacy cycle unit is for students to design a way to help a recycler separate aluminum from steel scrap metal. In previous lessons, they have looked at how magnetism might be utilized. In this lesson, students think about how they might use magnets and how they might confront the problem of turning the magnetic field off. Through the accompanying activity students explore the nature of an electrically induced magnetic field and its applicability to the needed magnet.

This lesson introduces students to the fundamental concepts of electricity. This is accomplished by addressing questions such as "How is electricity generated," and "How is it used in every-day life?" The lesson also includes illustrative examples of circuit diagrams to help explain how electricity flows.

Building on concepts taught in the associated lesson, students learn about bioelectricity, electrical circuits and biology as they use deductive and analytical thinking skills in connection with an engineering education. Students interact with a rudimentary electrocardiograph circuit (made by the teacher) and examine the simplicity of the device. They get to see their own cardiac signals and test the device themselves. During the second part of the activity, a series of worksheets, students examine different EKG print-outs and look for irregularities, as is done for heart disease detection.

Students are presented with a hypothetical scenario that delivers the unit's Grand Challenge Question: To apply an understanding of nanoparticles to treat, detect and protect against skin cancer. Towards finding a solution, they begin the research phase by investigating the first research question: What is electromagnetic energy? Students learn about the electromagnetic spectrum, ultraviolet radiation (including UVA, UVB and UVC rays), photon energy, the relationship between wave frequency and energy (c = λν), as well as about the Earth's ozone-layer protection and that nanoparticles are being used for medical applications. The lecture material also includes information on photo energy and the dual particle/wave model of light. Students complete a problem set to calculate frequency and energy.

In this activity, the students will complete the grand challenge and design an electromagnet to separate steel from aluminum for the recycler. In order to do this, students compare the induced magnetic field of an electric current with the magnetic field of a permanent magnet and must make the former look like the latter. They discover that looping the current produces the desired effect and find ways to further strengthen the magnetic field.
