Solar Mobile

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.

Our Sensational Sun

Grades:
3-5
Lesson Number:
3
Description:

The purpose of this lesson is to record information that the students learn about the sun on a chart. This chart will be used for the entire unit. It will serve as a good reference for guiding the lessons and providing information for student research.

Solar Mobile Design Challenge - Construction

Grades:
6-8
Lesson Number:
5
Description:

This is the culminating hands-on project for the Solar Mobile Design Challenge Lessons, with construction aligned to an engineering design process. Students start by Restating the Design Problem that was introduced to them in the beginning of the Unit....

Learning Goal(s):
Students brainstorm ideas and share with their group.Students draw and label Solar Mobile designs in Engineering Notebooks. Students research an aircraft to trace (if this was not accomplished in the Center of Gravity lesson) and trace the aircraft outline onto foam board. Students construct a solar circuit to power motors and propellers on a foam board aircraft and test multiple times before adding to the solar mobile stand. Students construct solar mobile stand and add their aircraft to a dowel attached to the central hub. Students work with a partner to balance each aircraft onto the mobile. Students test the mobile speed outside (depending on weather) and compare to speed under indoor light stands. After initial testing, students redesign circuits or mobile construction to optimize design. Students use hand-held devices to film their moving Mobiles to judge the machine’s speed. Students demonstrate how their Solar Mobile works and justify in writing why their mobile should be chosen for the Children’s Technology Museum.
