Bioreactor Water Circulation System

Grades:
7-12
Lesson Number:
3
Description:

Solar energy is available when the sun shines but energy can be supplemented at night by the decomposition energy in a bioreactor. In this activity we will experiment with the feasibility of using heated water in a bioreactor to circulate it through a...

Exploring Center of Gravity

Grades:
6-8
Lesson Number:
3
Description:

Since the concept Center of Gravity (mass) is a key factor in a mobile, students will participate in some activities to help them experience and understand this principle so it can be applied to their final Solar Mobile design. This lesson starts with a...

Learning Goal(s):
Students will observe a discrepant event and write down questions about what they observed. Students will participate in a variety of activities using a meter stick in order to experience and learn about center of gravity.Students will find the center of gravity of an irregular shaped paper object by using a plumb line. Students will apply the concept of Center of Gravity and find the center of their solar aircraft that is to be used on their solar mobile.
