Algebra in Science

Summary: In this Hurumanu, we have been learning how to solve algebra and geometry. Angles, tessellations, rotation, reflection ect. This has helped us understand geometer better.  

Reflection: What I like about this Hurumanu is that the teacher made it easy to understand what to do. Also when we did not understand he help us and encouraged us to get better.

Here is our slideshow showcasing our learning in algebra:



We showcased our learning of algebra with using the formula of speed. V=d/t (Velocity = Distance/Time). We flew paper planes and divided the distance they travel by the speed they travel. Some that it equals how many meters per second the plane could travel.

Lemon Power

Lemon Power:

Voltage: The energy that electrons get from a power supply.

Current: The movement of electrons.

Aim: To create voltage out of a lemon.

Method: 

• Roll the lemon out so the inside is liquidy.
• Stick a piece of zinc and copper into the lemon.
• Connect the lemon up to a voltmeter.

Results: 

One lemon: 1 voltage

Two lemons: 2 volts

All of the lemons: 2.3 volts

Discussion: When we rolled the lemon we made the inside liquidy. Because we rolled the lemon we freed the acidicly charged particles. The acidicly charged particles moved around creating a current. More lemons more acidicly charged particle meaning more voltage.

Conclusion: This experiment worked showing how a lemon can create voltage. Next time I would try to make sure the lemon doesn't leak so much.
