Standardized test practice

Try the first part of the virtual lab.  Remember inside the nucleus when the DNA is being copied to make new DNA, the T-A pair up and the C-G pair up.  In this instance, you are trying to make mRNA, so the C-G are still pairing up, the T-A pair is still happening (from the DNA to the mRNA) but the A-T pair is changed to a A-U when mRNA is being created

Here are the answers for the Chapter 9 review found on pages 266-267 in your book...
10.  B
11.  C
12.  B
13.  D
14.  D
15.  C
16.  D
17.  D
18.  Decay can destroy organisms if they aren't buried fast enough.  Erosion destroys some rock layers.  Materials that have been buried very deep are often destroyed by metamorphosis.
19.  You could determine the absolute age of the lava, because it contains radioactive elements.  The relative age of the rocks above and below the lava flow can be determined.
20.  The volcanic ash would have been deposited very quickly (during one specific volcanic eruption).  Therefore you have a rock layer that you know is the same age everywhere.  This could also be dated using radioactive isotopes.
21.  The cold temperatures preserved the entire woolly mammoth.  This is similar to how freezing preserves foods. mmmmm woolly mammoth!

22.  The fossils that are trace fossils are:  dinosaur footprints, worm burrows, and fossil woodpecker holes.
       The fossils that are body fossils are: dinosaur skulls, insects trapped in amber, and fish teeth.
23.  I might make you draw a sketch of a disconformity or an angular unconformity.

There will most likely be a question or two related to the half-life lab that we did... as an example... how many half lives did the element go through if there is 25% of the original element and 75% of the daughter element present.

Open House

The Elkhart Lake-Glenbeulah School District will have an open house this week Thursday.
Stop in to see what the middle school students are up to.

I hope to see you on Thursday, Feb 3rd from 5:00 - 7:00pm!

7th grade (chapter 8) practice test questions

Section 1
Section 2
Section 3 (not question 3)
Section 4
Standardized test practice (not question 3, question 2 is incorrectly written... it doesn't label the cell wall)
Review Quiz (not 8, 13) 

We have also worked with the microscopes.  Be prepared to identify the related items that were frequently mentioned (revolving nosepiece, stage, coarse adjustment knob, fine adjustment knob, high-power objective, low-power objective). 

I would suggest completing the Chapter 8 review on page 240 in your book...
The answers for Q 11-15, 17-21, 24, 26, & 29
11.D
12.D
13. A
14.A
15.D

17. B
18. D
19. C
20. C

21. A couple of the following items shoudl be thought about... a bird is made up of cells, it uses energy (to fly/move), it breathes, reponds to the environment, reproduces, has a life-span, and maintains a constant body temperature.

24. Once a virus infects a cell it uses the cell to make more viruses.  No drugs kill viruses (they aren't living), so your immune system has to work to get rid of viruses (if that is possible... your body can't get rid of the HIV/AIDS virus)

26. circular muscle cell, small intestine, digestive system, human

29. prokaryotic cells don't have organelles (such as a nucleus, or chloroplasts, or mitochondria, etc).  A plant cell has a cell wall, chloroplasts.  Animal cells have neither the cell wall or chloroplasts.
