Physical Science B (Tuesday)
Bellwork:
1. What are four problems that result from the use of any water related power sources?
2. Should the government be allowed to mandate the instillation of windfarms and windmills in certain areas?
3. Explain the different ways that solar energy is used and collected
Objectives:
1. Be able to list and explain the different types of fossil fuels used today.
2. Be able to list and explain the different types of renewable energy resources options available to people.
Today, we will look at our biodiesel. We will be comparing it to standard diesel in terms of energy output. To do this we will burn a small section of rope that has been soaked in the fuel and use the energy released in the bonds to heat water. The fuel with the greatest increase in water temperature can be correlated as the better fuel source.
Finish renewable resources.
HW: Your review will be handed out to work on after the lab. Please work on this and we will go over them tomorrow. We will also have a practice test tomorrow. The test will be on Thursday.
Physics B (Tuesday)
Bellwork:
1. Why would large concave mirrors be a difficult sale to make as dressing room mirrors?
2. Why do certain laundry detergents claim that their product will make your clothes even brighter?
3. If black absorbs all light, how can we see a black shirt as black?
Let's go over the math problems. Use the whiteboards.
Quick quiz, we will check to see how your studies have been going.
Discuss refraction of light.
Demo, fish tank, coin in a cup.
Go over ray diagrams for lens.
HW: Ray diagrams for the thin lens.
