1. The Scientific Process Answers must be in the form of a question.

2. What’s the Matter? It’s Just a Phase Mixing It Up One for the Littlest Guy Let’s Get Physical/ Chemical 100 200 300

3. A scientist would use a balance, rather than a scale, to measure it. What’s the Matter – 100 points

4. This is the measure of the average amount of motion in the particles of a substance. What’s the Matter – 200 points

5. This properties of metal make it very useful for people trying to put lights in their homes. 100 Bonus points! A thin metal wire is also useful for the above reason and this. What’s the Matter – 300 points

6. The closely packed, quickly vibrating molecules of ice prove that it is in this phase of matter. It’s Just a Phase – 100 points

7. True/False Any time a liquid turns into a solid, it is a physical change. Hint: Think about water. Now think about an egg. It’s Just a Phase – 200 points

8. Sunlight, fire and lightning are examples of this type of matter. It’s Just a Phase – 300 points

9. Daily Double! Get double points for answering all parts correctly. Give three examples of a solution. Give three examples of a mixture that is not a solution. Give one example a single substance that is an easily separable (easy to separate) mixture and a solution. Mixing It Up – 100 points

10. This is how likely it is (the degree to which) that one substance will dissolve into another. Mixing It Up – 200 points

11. Daily Double! Get all parts right for double points! Mr. Washington made a mixture of sand, salt, and iron filings (little iron bits). These are the tools his students used to separate each bit. (Hint: for one you have to add something!) Iron filings: Sand: Salt: Mixing It Up – 300 points

12. This is the idea that tiny particles called atoms make up everything. The Littlest Things – 100 points

13. Atoms each element will always have the same number of these types of particles. For example: A carbon atom will always have 6 An oxygen atom will always have 8. A Helium atom has 2. An iron atom always has 26. The Littlest Things – 200 points

14. Pencil lead (graphite) and diamonds have different properties because the carbon atoms in each do this. The Littlest Things – 300 points

15. Putting a tomato slice into a blender will cause this kind of change. Let’s Get Physical/Chemical – 100 points

16. Baking a tomato slice in the oven will cause this kind of change. Let’s Get Physical/Chemical – 200 points

17. This is a chemical change in which atoms of iron bond with atoms of oxygen, making the metal turn from gray to brownish red. Let’s Get Physical/Chemical – 300 points
