All classes will meet in the library to continue work on the Changes in State HyperDoc.
You should be completing the yellow Explore Section and beginning the pink Explain section. In the yellow Explore Section, you have explored how heat energy transfers through conduction in the Heat, Temperature, & Conduction Lab and you have explored how particles in different states of matter respond to changes in heat energy and pressure in the States of Matter PhET Simulation. In the pink Explain section, we will start to use the resources (infographic, video, and reading) to learn about changes of state. Our learning goal is to be able to explain how heat energy changes affect particle motion, temperature, and state of matter.
You can use the following links to get to the post in Google Classroom for your class:
- The changes of state that occur with variations in temperature or pressure can be described and predicted using models of matter
- Heat refers to energy transferred due to temperature differences between two objects
- Do Now- Copy down today’s homework assignment in your planner. Get out your science notebook and open to page 49. Turn to your table partners and practice explaining what happens to particles in the following changes of state: evaporation, condensation, freezing,melting
- Application- Answer questions 4, 5, & 6 on the handout about melting and the comparison of state changes in other substances to state changes in water. Tape handout to page 48 as flip page.
- Review of Changes of State for quiz- BBC, How Stuff Works, Mystery Mud
- Do Now- Copy down today’s homework assignment in your planner. Get out your science notebook and add to the Table of Contents- “Melting p.48” (Left Side) and “Melting p.49” (Right Side). Open to page 48 and head it properly with “Melting-Application-1/17/17 and open to page 49 and head it properly with “Melting-Demonstration-1/17/17.”
- Model– Observe the animations of Ice structure Ice at Different Angles. Create a model of water molecules in solid ice and liquid water on p.46. Freezing Point of Gas- Liquid Nitrogen Demonstration Let’s Freeze Liquid Nitrogen
- Demonstration– What happens to the speed of molecules in ice when it is heated? Where does the energy come from to melt the ice? Describe your observations of the ice melting on different surfaces on page 49. Define melting. Add key term to index at back of notebook.
