Human Impact on the Environment and Renewable Energy Debate

Students work to create research guides from reputable sources about a specific energy source given to them.  After being placed within groups, students create arguments for and against the energy source based upon their research and prior knowledge of renewable versus non-renewable energy resources.  Groups then report to the classroom about their findings.

Investigating Circuits with Multimeters

The lesson will lead the students to more thorough understanding of how electric energy moves through different objects. The class will use a hand-on, inquiry lab to establish a quantitative way to measure the flow of electricity through a simple circuit with multiple resisters in place. The students will use a multimeter to measure the current (I) and voltage (V) at several locations on the circuits they build. They will use the information they gather to formulate an idea about the relationship between voltage and resistance and the brightness of the flashlight bulbs. The students will then be asked to predict how it will work on a bigger scale, like their own house.

Electric Charge

Day two in the Forces of Nature Unit will be less hands on with a large lecture component that will be used introduce the Law of Electric Charges and to make certain the necessary vocabulary is in place to effectively move forward in the unit. A computer simulation will be used to show how electric charges and electron move from one object to another. This will be the basis for understanding current and voltage in a future lesson. Students will complete a group activity towards the end of the class to reinforce the vocabulary presented during the lecture. An extension will provided for the honors classes and the any others that would like to try to make their own electroscope at home that they can use to identify charged objects in their house.

Magnets

Students will be given the opportunity to investigate the invisible properties of magnets and electricity using a simple kit provided by the instructor. Students will be expected to answer some guiding questions using the appropriate vocabulary learned in previous grades. This lesson is intended to check for understanding of the vocabulary and evoke an interest in electricity, electrical charges and the transfer of energy that will be built upon over the next several days.
