Lesson Plans

Marshmallow Missiles:

In this activity, students will learn the differences between kinetic and potential energy. To measure their understanding, they will complete a lab activity that will help them launch a projectile and compare how the kinetic and potential energy can differ the outcome of the launch. Students will need two 45-minute days to complete this lesson.

Energy Transformations at Santa's Enchanted Forest:

This activity allows students to demonstrate their knowledge and understanding on forms of energy and transformations in a fun way. This lesson is based on an annual carnival in the community during the Christmas season. After learning about different forms of energy, how the transform from one to another, and the Law of Conservation of Energy they apply that to some of their favorite and popular rides at the carnival. This lesson allows for the arts in S.T.E.A.M. to be addressed.

Transformation of energy at the level of microprocessors:

This is a lesson plan that will help students to understand that the Law of Conservation is applicable to all systems in nature, including their cell phone that they use regularly. It means that energy, though it might seem to have been created or destroyed, is actually conserved, but simply transformed from one form to another.

Type: Lesson Plan

Daring Dive:

This resource is designed for students to better understand energy. It is designed to teach students using a more engaging and hands-on approach by having students examine the energy transformations during a bungee jump (by building a model bungee cord with rubber bands).

Type: Lesson Plan

Spread the Sunshine MEA:

In this MEA, the sun is asking students to provide an advertisement explaining how the sun's energy is used to provide energy every second of every day. Students are asked to provide many examples of how solar energy is transformed into electrical, thermal, and other types of energy. Students are then asked to develop a presentation for the media outlet of their choosing. This MEA can be scaled down for differentiation, or used as is for a challenge to engage students in a rigorous fun activity.

Type: Lesson Plan

Marble Run – Kinetic and Potential Energy:

Students investigate and explore kinetic and potential energy on a roller coaster and a marble run.

Type: Lesson Plan

Family on the Go:

The main problem students will need to rank the best hybrid car for the family to buy which shows the most fuel efficient, highest safety rating, best price, and most comfortable car for a family of four. The family is interested in a hybrid. Students will then be asked to look over their finding and evaluation checklist and change the four passenger vehicle to an SUV in order to fit grandma and grandpa that will soon be moving in. The students will be given new data set that includes all SUV's currently on the market. They will use the ranking formula they devised to figure out the best SUV for the family. Next, they write a letter to the family explaining their findings and the reasons for their choice.

The Power of Energy:

Have you ever wondered how energy changes from one form to another? How you can put food in microwave, and seconds later it is hot? What happens between the time you plug in a TV and you see a picture? Students will take a deeper look into energy. What are all of the kinds of energy that help an object work? This lesson is a fun way to involve kids in their learning and include technology to present.

Type: Lesson Plan

Hot Sand:

Students investigate how energy transfers and how motion affects temperature.

Type: Lesson Plan

Finding Impact Craters with LandSat:

Students examine and write about the effects extraterrestrial collisions might have on the land, atmosphere, water, and living things. Students then read descriptions of the actual effects of impact events and the evidence these leave behind. To demonstrate their understanding of the role of impact events in shaping the Earth, students write a series of guidance questions for a field expedition to determine whether or not a given landform is an impact crater.
