1. Wed 1/7 1. It is 21,000 kilometers around the earth and the earth rotates in 24 hrs. How fast is it rotating? If you drive at 100 km/hr for 6 hours, how far will you go?

2. Thur 1/8 2. A – B 10 m/s B – C 0m/s C – D 10 m/s D – E 40 m/s

3. Mon 1/12 (write the yellow 3. Boy X and Boy Y both move backward. The motion depends on how hard Boy X pushes.

4. Tue 1/13 4. Calculate the average speed for each ( answers only ) 1. A person walks 6.0 meters in a time of 2.0 seconds. 2. It takes 30 seconds for a bird to fly 120 meters. 3. At 8:01 a jogger sets out. By 8:04 she has run 360 meters. 4. A rock climber takes 10 minutes to climb 30 meters vertically. 5. A ball rolls 2 meters in 5.0 seconds. 1.3 m/s 2.4 m/s 3.120 m/min 4.3 m/min 5..4 m/s

5. Wed 1/14 5. What happened?

6. Thur 1/15 6. What is volume? How do you find the volume on a rectangle? The amount of space matter occupies. Length x width x height

7. The salt concentration of the Dead Sea fluctuates around 31.5%. This is unusually high and results in a nominal density of 1.24 kg/l. Anyone can easily float in the Dead Sea because of natural buoyancy. In this respect the Dead Sea is similar to the Great Salt Lake in Utah in the United States 7. What is the formula for density? Density = mass / volume Mass = 50g Volume = 40ml What is the Density? D = 1.25 g/ml

9. Thur 1/22 8. What is the volume of 1,000,000 ml of water? 1,000,000 ml

10. Tue 1/27 9. What is a mineral? How are they identified? Natural Solid Inorganic Crystalline structure Formula hardness Color Streak Luster Fracture

12. __________________________________________________________________ Changing the Density of a Liquid Question: Can the density of a liquid be changed? Materials  Two cups  Slice of carrot  Salt  Teaspoon Procedure 1. Half-fill a plastic cup with room-temperature water. 2. Place a slice of carrot in the cup. It should sink because it is denser than water. 3. Add about 1 teaspoon of salt and stir with a spoon until as much salt dissolves as possible. 4. Continue adding salt and stirring until the carrot floats to the top. 5. Very carefully, add fresh water to the top of the salt water until the carrot begins

13. 1.Weight - is the measure of the force of gravity on an object. 2. Mass – the amount of matter in an object.

14. 3. Volume – the amount of space matter occupies. 4. Density – the amount of matter in a substance compared to its volume.

15. 5. Mineral – natural, inorganic, solid, chemical formula and has crystal structure. 6. Hardness – a minerals ability to resist being scratched.

17. 7. Color – not reliable because some minerals come in many different colors. The same is true for the mineral quartz. It occurs in many colors, but they are all quartz

18. 8. Streak - color of a minerals powder.

19. 9. Luster - the way a mineral reflects light from its surface.

20. 10. Mineral fracture - how a mineral breaks.

21. 11. Rock - solid material made up of one or more minerals.

22. 12. Igneous rock - forms when magma or lava cools and hardens 13. Intrusive – cools beneath the ground 14. Extrusive - cools above the ground

23. 15. Sedimentary rock - rock formed from the compaction and cementation of sediments. 16. Erosion – the moving of sediment from place to place. Running water 17. Deposition - sediment deposited

24. 18. Metamorphic Rocks - have been changed over time by extreme pressure and heat.

25. 19. Rock Cycle - a continuous process by which rocks are created, changed from one form to another, destroyed, and then formed again.
