In this lesson, the students will conduct an investigation to purify water. Students will engineer a method for cleaning water, discover the most effective way to filter water, and practice conducting a scientific experiment.

This lesson uses a hands-on approach to teach about renewable energy with a case study in wind turbines. This lesson also uses engineering design to help situate renewable energy within a practical human society.

Students will learn the difference between global, prevailing and local winds. In this activity, students will make a wind vane out of paper, a straw and a soda bottle and use it to measure wind direction over time. Finally, they will analyze their data to draw conclusions about the prevailing winds in their area.

Students learn about wind energy by making a pinwheel to model a wind turbine. Just like engineers, they decide where and how their turbine works best by testing it in different areas of the playground.

Windmills have been used for hundreds of years to collect energy from the wind in order to pump water, grind grain, and more recently generate electricity. There are many possible designs for the blades of a wind generator and engineers are always trying new ones. Design and test your own wind generator, then try to improve it by running a small electric motor connected to a voltage sensor.

In this activity, students develop an understanding of how engineers use wind to generate electricity. They will build a model anemometer to better understand and measure wind speed.

Students learn how engineers transform wind energy into electrical energy by building their own miniature wind turbines and measuring the electrical current it produces. They explore how design and position affect the electrical energy production.

Students research the feasibility of installing a wind-turbine distributed energy (DE) system for their school. They write a proposal (actually, the executive summary of a proposal) to the school principal based on their findings and recommendations. While this activity is geared towards fifth-grade and older students, and Internet research capabilities are required, some portions of this activity may be appropriate for younger students.

In this breakout room activity students will obtain the information needed to answer the questions, which will break out code words needed to use to complete the final breakout challenge page.

To explore different ways of using solar energy, students build a model solar water heater and determine how much it can heat water in a given amount of time. Solar water heaters work by solar radiation and convection.

--In this activity student will create an amusement park ride out of KNEX that displays a certain type of motion. They will describe their ride. They will then place it in the correct spot on the map by writing the name of it on the worksheet. After all groups have their rides labeled on the map- students should fill in the lines section of the worksheet- identifying parallel, perpendicular and intersecting lines.
