Density & Changes in Matter Study Guide

This seems a bit boring so I'll take a power nap!
Wake me up for dinner.
2 bonus points for the first student to post a comment!

OK, so what is a blog? It is a web site that you can easily post a comment too. Just go to the bottom of the blog, after the study guide, and click on the comment link. You can now add a comment to the blog. Your comment may be a question on one of the study guide numbered questions or it may be to answer someone else’s question.

Remember to NOT USE YOUR FULL NAME. First names are fine and you can even use your science period number of letter. If you choose to make your own blog get your parent's approval first! Again... do NOT put your address, full name or other info that would make it easy for an online weirdo stalker to track you down. Best to error on the side of caution, less is MORE!!!

In the past student have also used the blog to communicate with each other. I have no objection to this as long as it does not get in the way of the learning/studying focus of the blog.

Keep it NICE! You know what I mean! There have been few abuses in the past and I see no reason that this year's science students will let me down or embarrass our school.

Remember... if you all get A's I still get paid! Take advantage of the study guide and earn an A, heck even an A+!

When you get a chance you might want to visit John C’s semi-cool blog at www.hubofgates.blogspot.com – A word of caution though, John is the head of an elite combat ready Typo Police organization that has been stalking my site for over a year now.

Have fun and best of luck on the test,
Mr. Carrison & Flash

Density and Changes in Matter Study Guide
by Mr. Carrison - Gates Intermediate School - Scituate, MA

1. Without looking at your notes, from memory do you know the formula for density? What gets divided into what???

2. Why are some materials denser than other materials? Simply put, what is the reason?

3. What are some practical uses for density?

4. Materials with a density greater than one will ____________ in water.

5. Flash is wondering what the significance of knowing if a material has a density of less than one?

6. If you are given some data on Thursday's test can you figure out the density?

7. Considering #6 will you need a calculator on the test? Plan ahead!

8. Should you run across a couple of metric review questions will you be able to correctly answer them?

9. I know what UNITS the density data should be in and the final product or density units are, do you???

10. What is the conversion factor between cc, cm3 and ml? Can you convert between the three?

11. When Flash digests his beloved dog food at the cellular level is the process of getting at the stored chemical energy in the food endothermic or an exothermic chemical reaction?

12. When you sweat the water/sweat evaporates. This leaves you feeling cool. Why? Is evaporation an exothermic or endothermic reaction?

13. When an ice cube changes state from ice to water is this an exothermic or endothermic reaction?

14. You should review your vocab sheet and know all the terms.

15. Review heterogeneous and homogeneous mixtures!

16. Around your home and our school how many states of matter can be found? I would know all of them!

17. When you did the last lab what did you learn about the density of a part or small sample and the density of a much larger sample of the same substance?

Do to popular demand here are the words/topics from the vocab list:

>Physical Change
>Chemical Change
>Energy
>Law of Conservation of Mass
>Thermal Energy
>Endothermic
>Change
>Exothermic Change
>Temperature
>Hypothesis
