Name:_____________________________ Period: 1 2 3 4 5 6 7 Date:_________________ Matter and Density Note Guide 1. What is matter? 2. List 2 examples of matter? 3. List 2 examples of things that are not considered matter? 4. What is an atom? 5. Atoms are made up of protons, neutrons, and electrons. Describe the location of where I might find these parts within an atom and some of their physical characteristics. Protons: Neutrons: Electrons: 6. Describe the two problems with the current atomic model we use in class. 7. What is a molecule? List a few different examples of molecules. 8. Have we seen atoms under a microscope? 9. Why have our ideas about atoms changed so much over the last several hundred years? 10. Define the following terms: Volume: Mass: Energy: Density: 11. List the 4 states of matter in at least 4 examples for each state of matter. 12. For each of the phases of matter describe how the molecules behave in that state of matter, how much energy the molecules have, and the relative density of each phase of matter. Phase of Matter Atoms Behavior Amount of Energy Relative Density 13. What is a phase change? Why do phase changes occur? 14. Describe each type of phase change and include a detailed example of that phase change. Phase Change Description of Phase Change Example of Phase Change 15. What are the units of measurement for volume? 16. How do I measure the volume of a liquid? 17. How can I measure the volume for a solid such a square or a rectangular object? (Equation) 18. How can I measure the volume for an irregularly shaped object such as a rock? (Explain) 19. Write down the 2 volume practice questions below. Calculate the volume for a book and then for a CD case. 20. Mass and weight are not the same thing. List the 4 differences for mass and weight below. Mass Weight 1. 1. 2. 2. 3. 3. 4. 4. 21. Mass and weight are not the same thing but they are related. How is mass related to weight? 22. What are the two factors that influence density? What is the equation for density? What are the units of measurement for density? 23. If the mass of an object goes up or down how is the density effected? 24. If the volume of an object goes up or down how is the density effected? 25. Write down the practice problems for density below. You are figuring out the density for a race car, a fish tank, and then an igneous rock. Race Car: Fish Tank: Igneous Rock: 26. What is the density of water? If an object floats in water what can I say about that objects density? If an object sinks in water what can I say about that objects density? Density of Water: Objects Floating in Water: Objects Sinking in Water: 27. How does the density of rocks or sediments influence their sorting in a river bed? 28. When I blow up a balloon have I increased or decreased the density of the balloon? 29. If I blow up a balloon with my regular breath it doesn’t float away but when I blow it up with helium balloons float to the ceiling or to the sky? Knowing what you know about density why would that happen? (This is not directly in the slides) 30. What are the 4 layers of the earth? Which layer of the earth is the most dense and which layer of the earth is the least dense?
