Newton's Laws

We will complete a lab with mousetrap cars that focuses on energy transfer, problem solving, and engineering design.

Then we will begin Newton's Laws of Motion. The first law will be discussed Wednesday. I will put some info on Google Classroom.

Thursday is BASH DAY! No new material will be covered. No school Friday!!! Enjoy your long weekend. We will pick up Newton's Laws on Monday of next week.

Study Guide for Energy Quiz

Renewable Sources of energy: Wind, Hydroelectric, Solar, Geothermal

Nonrenewable Sources of energy: Fossil Fuels (coal, oil, gas) and Nuclear

Types of energy:

Potential:

• Chemical
• Nuclear
• Stored Mechanical 
• Gravitational

Kinetic: 

• Radiant (light) 
• Thermal
• Motion
• Sound
• Electrical

Law of Conservation of Energy

Study all worksheets and notes given in class as well as the powerpoints on Google classroom.

Energy

We are starting ENERGY tomorrow! The are two different forms of energy: kinetic and potential. There are 7 types of energy: chemical, nuclear, thermal(heat), electrical, light, mechanical, and sound. Study this vocabulary!

Study

Students should be able to identify, explain, and provide examples of these words:

• atom
• compound
• mixture
• element
• solution
• chemical formula
• chemical symbol
• solvent
• solute

Students should know:

• 3 things that affect solubility: temperature, size of solute, and stirring/shaking
• how temperature affects the solubility of sugar
• 5 separation techniques: filtration, settling, chromatography, evaporation, magnetic attraction
• how temperature affects the ability of a liquid-gas solution
• how pressure affects the solubility of a liquid-gas solution
• how to read a solubility graph

Student need to know some common compounds:

• water-H20 (2 atoms hydrogen, 1 oxygen)
• methane-CH4 (1 carbon, 4 hydrogen)
• carbon dioxide-CO2 (1 carbon, 2 oxygen)
• rust-NH3 (1 nitrogen, 3 hydrogen)
• salt-NaCl (1 sodium, 1 chlorine)
• hydrogen peroxide-H2O2 (2 hydrogen, 2 oyxgen)

Finishing up Chemistry

We took our mixtures and solubility quiz today. We are going to work some more with solubility graphs this week and review what we have learned in this unit. We will then take a final Chemistry Test Thursday worth 80-90 points. I am giving them a regular sized index card where they can write whatever they want on it and bring the test. I think it will encourage note-taking and consolidating facts. We are starting from atoms and going all the way to mixtures with everything in between.
