**For each layer: is it rock or metal?  Molten or solid?  Use pages 110-113 in the textbook to help you with this**

New resources added!

Check out the resources page for two new items:

• Paleo and Eco study guide
• Science Fair packet

Remember... if you complete the study guide TONIGHT and miss <5 answers, you will receive 5 points extra credit on tomorrow's test!

Also, the question for science fair is due tomorrow.  See the packet if you have further questions!

Graphing for lab report

Students - I have received some requests for directions on how to do the computer based graph.  Please remember that I went over how to do this IN DETAIL in class, and that this is also for extra points.  Please understand that it is YOUR responsibility to pay attention when it comes to extra credit.  I will always post things that are necessary for your success in class, but you must also put in effort when in comes to extra credit.

I will not be posting step by step instructions on how to graph on the computer.  You may also turn in a hand-drawn graph, google directions, or ask a friend that WAS paying attention when I explained this in class :)

Parents, do you sew?

Are you willing to donate a little time to the team for a sewing project?  And by sewing, I only mean straight lines :)  No couture ball gowns any time soon!  Please send me an email and let me know!  ashley_shaver@gwinnett.k12.ga.us

Half-Life lab analysis questions and conclusion

Analysis:
1. Approximately what fraction of chips was removed from the shoe box after each set of 5 shakes (half-life)?

2. How many times did you shake the box before only one chip remained?

3. If someone stopped you and counted only 12 chips remaining, could he or she have calculated the time (in # of shakes) you started the experiment?  Explain!

4. Imagine that the shoe box is a fossilized bone that contains 24 pug (picomicrogram) of Carbon-14.  When it was buried, it contained 100 pug of Carbon-14.  If the half-life of Carbon-14 is 5730 years, how old is the bone?  Show your work.

5. Based on what you learned in question 4, how many pug of Nitrogen-14 is in the bone?  How much did the bone start with?

Conclusion:

Was the hypothesis correct? 

How could you change this experiment to ensure more accurate results?
