2. Presentation Cues
No one wants to listen to the teacher the whole time;)
Volunteer/Class Discussion – quick answer from raised hand (remember/understand)
Pair/share – quick chat with neighbor and volunteer or teacher pick share (remember/understand/apply)
Group task – longer time for pair or group to apply, analyze, evaluate or create
Individual write – personal reflection on topic
Rotations – solve the station with group and write answer on paper, rotate with timer and stay with your group
5?Quiz – quick check for understanding about topic

3. Materials needed Group whiteboard Dry erase markers Eraser
Timer – consider

5. Expectations NO ELECTRONICS – unless we’re using them for science
Late assignments – 75%
May fix only 3 incompletes
May correct as much as needed – I can tell the difference
Use highlighter to emphasize vocab in notes so you can find it!!!

6. Fill in anticipation guide…

7. Answer the following questions as you read…
N19: DNA
DNA
Answer the following questions as you read… p.

8. We need to know 5 words….
DNA
Double Helix
Chromosome
Gene
Nucleotide

9. DNA is..
the shortened name for DEOXYRIBONUCLEIC ACID

10. DNA is…
genetic material inside of each cell

11. DNA is..
the instructions for an all of organism’s functions.

12. DNA is.. protected in cells by the nucleus.
Looks like ball of yarn most of the time

13. DOUBLE HELIX is… Structure of DNA two sides and is twisted,
like a twisted ladder.

14. CHROMOSOMES are…
sections of DNA wrapped around proteins.

15. CHROMOSOMES are…
Always found in pairs
Like socks!

16. CHROMOSOMES are…
Males: XY
Females: XX

17. CHROMOSOMES are…
Every organism has a specific number of chromosome pairs.
Humans have 23 pair,
dogs have 62 pair,
flies have 8 pair,
cows have 60 pair
corn have 20 pair.

18. GENES…
appear as bands across the chromosome pair.

19. GENES…
About 20,000 in humans
Each chromosome has around 1000

20. GENES…
Specific section of DNA

21. NUCLEOTIDES The smallest piece of DNA
The order they are written in determines the meaning of DNA

22. NUCLEOTIDES
Molecules with long names:
A, T, G and C.

23. NUCLEOTIDES
Connect in pairs from each side of double helix to hold molecule together A –T & G-C
“All Teachers Go Crazy.”

28. How is DNA of each human similar?
All Double Helix
All in nucleus
All have 23 Chromosomes
All have 20,000 Genes
All written with A-T and G-C

29. How is DNA of each human different?
Order of Nucleotide pairs is different within each gene
Males XY while Females XX
