Curriculum starts Wed/Thurs. I will try to update this site daily at the end of the day to indicate what we actually accomplished during the day.
Day 1: SLCT Days Ground rules, comfort zones, overview of reproduction and development, life cycles
Basic human male and female reproductive anatomy
Wednesday and Thursday: we covered the topics listed above, reminding students about internal vs external fertilization, sexual vs asexual reproduction
Day 2: Mrs. G will be out of the classroom and the students will watch a video about circulation (unrelated to topics in Chapter 16) with the substitute.
Day 3: Hormones, puberty, menstruation
Day 4: Pregnancy and the human life cycle,
Day 5: NOVA video “Life’s Greatest Miracle” fetal development
Day 6: Second half of NOVA video “Life’s Greatest Miracle” (with birth sequence) Abstinence, birth control, safe haven law
Day 7: Infectious disease and AIDS vocabulary; Video “AIDS, Facts for Young People”
Day 8: Sexually transmitted diseases: Disease agents, symptoms, treatments
Day 9: Identifying risky behaviors, refusal skills, video “Saying No to AIDS”
Day 10: Catch-up, Questions
Answers to Chapter 1, Section 3
1. Scientific inquiry refers to the processes we use to find out about the natural world.
2. TRUE
3. a, b; c and d, much less likely since c would be hard to control and d involves personal tastes.
4. A hypothesis is a possible explanation….
5. False. If a hypothesis is supported by lots of testing, it might achieve “fact” status.
6. A testable hypothesis is one that allows scientists to collect evidence that either supports it or disproves it. If you can’t test it, it’s not considered a worthwhile scientific explanation.
7. To test a hypothesis, a scientist designs a controlled experiment.
8 D 9 a 10 b 11 e 12 c CONGRATS TO ISABELLE TSENG FOR NOTIFYING ME OF THE ERROR :-)
13. TRUE
14. An operational definition makes it clear how you are going to measure your variable. Thinking back to the “Case of the Sleeping Frog,” Kara would have to figure out how to measure the temperature of her chambers. She probably decided something like she would measure “8 cm below the top rim of the jar” or “6 cm from the base of the inner jar.” She might define frog activity, one of her responding variables as “the number of times it shifted position in 2 minutes.” These are all operational definitions.
15. Facts, figures…are called data.
16. a and c are valid statements about graphs.
17.. A conclusion is a summary….
18. You might ask yourself if the findings support the original hypothesis, or not.
19. Pose a question. 20. Form a hypothesis. 21. Draw conclusions.
22. Scientific inquiry is a process with many paths because anywhere in an investigation you can think of a new of different questions, make an observation that makes you reconsider your hypothesis or experimental design, find information in the library or online or in interviews that changes the way you are thinking about your question.
23. Communicating is sharing your inquiry with others. Letting others see your data and conclusions, novel experimental designs, interesting observations, etc. helps the scientific community work efficiently and invites discussion and interpretation by the whole community.
24. a and b are ways scientists can communicate.
1) How did the measured volume and the calculated volume of the bean/bear compare?
PART TWO
2) Was your hypothesis correct? Explain. Give supporting details using your data.
3) Which change is greater, volume or mass? Explain.
4) Was there a change in density? Why?
5) How do your results compare to those of others in your group?
If you couldn't make a second day of measurements, comment on why that was. Be sure you made qualitative observations!
