Compost Heater

Compost Bioreactor Design

Grades:
7-12
Lesson Number:
2
Description:

Solar energy is available when the sun shines but energy can be supplemented at night by the release of energy during the composting of organic waste. In this activity, we will experiment with the feasibility of harnessing thermal energy to heat water with...

Learning Goal(s):
1. Students will research the science of composting and proper maintenance methods to build their own bioreactor. 2. Students will research the proper composition of compost for maximum heat production. 3. Students will transfer the thermal energy in compost to a container of water heat water with by placing a vessel in the middle of the active compost/bioreactor.

Simple Circuit

Introduction to Circuits

Grades:
7-8
Lesson Number:
2
Description:

This lesson begins with students having hands-on experiences creating electrical circuits using a battery, wires, and a light bulb. Students will learn that electricity is the flow of electrons, and how electricity moves within a circuit.

Wave Attenuator

Testing a Tidal Wave Attenuator

Grades:
6-12
Lesson Number:
3
Description:

Students will test the efficiency of the tidal wave attenuator models that they previously built. They will determine variables on their models they can manipulate, such as wire gauge and magnet strength, and measure the effects of manipulating this...

Learning Goal(s):
1. Students will investigate variables that may affect the output of an energy conversion device (wave attenuator). 2. Students will interpret data to identify which variables increase electrical output for these model wave attenuators. 3. Students will communicate results from scientific inquiry to identify factors that are important to optimizing the design of a wave attenuator.
