Grade 9

Ms. Ortiz's and Ms. Luna's classes

On March 7th, 2019 Grade 9 students presented their Energy Transformations projects at the AIS STEM Fair. For several weeks, students learnt about Work, Energy, Power and Energy transformation and they came up with an invention/prototype that shows one form of energy being converted into another one.

Please see below for the results. Click on the group pictures to access individual websites for each project where students show their planning process, their research paper and their final invention.

Grade 9 students, your Science teachers are very proud of all the work you have done during Quarter 3.

Hydropower & contact area

Project 1

Which contact area in 20mm (the most inner part of turbines), 30mm (the central part of turbines), and 50mm (the most outer part of turbines) away from the core of the generator best produce energy?

Doll, Uyen, Mike P

The use of electrical and mechanical energy

Project 2

How do the length of a DIY vacuum cleaner, the pen cane it in, and the thickness of its fan, affect its effectiveness?
