The RCEA Redwood Coast Energy Authority asked the Engineering 215 Intro to Design class at Humboldt State University in Arcata, California to design educational kits. These kits provide teachers of Humboldt County the tools that are necessary to teach kindergarten through 12th grade students about climate change, renewable resources , or energy conservation. This webpage describes one of these projects, Bust-A-Watt, which teaches fifth through eighth grade students about energy conservation.

Background and Objective

The RCEA is a Joint Powers Authority focused on implementing sustainible and renewable energy in Humboldt County.

At the beginning of the Spring 2010 semester they asked the Engineering 215 class at HSU to design educational kits that teach K-12 students about these energy topics. Team E2 of the Engineering 215 class was assigned to develop a kit that teaches fifth through eighth grade students about energy conservation. Over a 12 week period, Team E2; Elizabeth Gutierrez, Bryan Schmitt, and Logan Baumgartner, used the criteria they agreed upon with the RCEA to design and develop Bust-A-Watt; a five day comprehensive lesson plan that motivates and educates middle school students toward energy conservation.


Criteria were created by team E2 as a tool to structure the final design. The criteria were created in correspondence with RCEA's standards and expectations, and with input by Humboldt County teachers. In addition to creating the criteria a weight was given to each. The weight is a scale created by E2 to decide the level of importance of each criteria. Table 1 shows each criteria, its weight, and a description of that criteria.

Criteria Weight Description
Safety 10 Level of avoiding risk of injury and danger to any individual
Durability 10 Ability for the kit to last for atleast a one year with normal use
Amount of Real World Applicability 10 Amount of information that students will gain from the kit which pretains to real world applications
Cost 9 Amount of money spent on the kit from E2 and RCEA
Level of Engagement 8 Kit's ability to create student interaction during implementation
Compliance with Educational Standards 8 How many California State Math and Science Standards the kit contains
Ease of Use 7 Amount of effort needed by teachers to implement kit into the classroom and by RCEA to maintain at their office
Transportability 6 Ability for the kit to be transported from RCEA to the classroom without damage to insturments

Description of final project

Bust-A-Watt educates middle school students about energy conservation through hands on activities, interactive discussions, home assessment assignments, and  a reflective art assignment. Bust-A-Watt is a weeklong energy conservation unit, broken up into five one hour class periods, or individual daily activities. Three of the days consist of class discussions and two days consist of experimental activities.

Day 1

Introduction to Energy Unit

  • Discussion: Energy measurement and properties.
  • Home Checklist introduced- Students assess their own homes by completing a home checklist in which they consider the amount of appliances in their home and their amount of use.

Day 2

Figure 1. Blinding Heat docking station.

Blinding Heat Activity Students compare the wattage and temperature of a CFL and incandescent bulb.

Day 3

Appliance Energy Reading Activity Students measure the wattage of appliances common house hold appliances using a Kill-A-Watt meter when the appliances are on and off.

Day 4

Lighting Discussion Students calculate with teacher how much energy and money can be saved if the class switches their incandescent bulbs to CFL bulbs.

Day 5

Unit Conclusion Students reflect upon the unit by creating a poster displaying something they learned during the week.

Testing Results

Bust-A-Watt has been reviewed and edited by three local middle school and high school educators, the Redwood Coast Energy Authority employee Oliver Hulland, and Humboldt State University Environmental Resources Engineering Introduction to Design instructor Lonny Grafman throughout Bust-A-Watt's creation and production. These resources helped in the creation of Bust-A-Watt's criteria, as well as in the decision process, and in testing Bust-A-Watt in local middle school classrooms. During the week of April 19th Bust-A-Watt was implemented into a middle school science class at Laurel Tree Learning Center in Arcata, and on April 26th the Blinding Heat activity was implemented into a sixth grade science class at Washington Elementary School in Eureka. The testing results showed that discussions during the introduction of Bust-A-Watt did not fill the one hour block that was intended. The testing also revealed confusing aspects of the activity instructions which helped in editting them for testing at Washignton Elementary. After implementation at Laurel Tree Learning Center the students were given a short survey to fill out in which they were asked their favorite and least favorite parts of the lesson plan as well as which parts were confusing.
