Week 3- Bulbs, Batteries, and Wires

5 Essential Features of Inquiry

-    Learners are engaged by scientifically oriented questions.

-    Learners give priority to evidence, which allows them to develop and evaluate

explanations that address scientifically oriented questions.

-    Learners formulate explanations from evidence to address scientifically oriented

questions.

-    Learners evaluate their explanations in light of alternative explanations,

particularly those reflecting a scientific understanding

-    Learners communicate and justify their proposed explanations.

For this lab, we played with wires, batteries, and small light bulbs. It was my favorite one

we've done so far! I learned that a battery can light the bulb if a wire is touching both the

positive and negative ends of the battery and the side of the bottom of the metal part of the

lightbulb. We also talked about the insulators and conductors in a wire. Materials with high

electron mobility are called conductors. Materials with low electron mobility are called

insulators.

Kinetic VS Potential Energy

1. A chemical reaction creates chemical potential energy.

2. Batteries store energy as electric potential energy.

3. As a battery is used, the electric potential energy is converted to kinetic energy.

4. Once the potential energy is entirely used, the battery is dead.
