1.1
1. Review- What is Science
Explain- What kinds of understandings does science contribute about the natural world
Form an Opinion- Do you think that scientists will ever run out of things to study, explain your reasoning
2. A few hundred years ago, observations seemed to indicate that some living things could just suddenly appear: maggots showed up on meat; mice were found on grain; and beetles turned up on cow dung. Those observations led to the incorrect idea of spontaneous generation- the notion that life could arise from non living matter. Write a paragraph for a history magazine evaluating the spontaneous generation hypothesis. Why did it seem logical at the time? What evidence was overlooked or ignored?
1.2
1. Review- What is a scientific theory
Compare and Contrast- How does use of the word theory differ in science and in daily life
2. Review- What is peer review
Apply Concepts- An advertisement claims that studies of a new sports drink show it boosts energy. You discover that none of the study results have been peer-reviewed. What would you tell consumers who are considering buying this product
3. Review- How is the use of science related to its context in society
Apply Concepts- A study shows that a new pesticide is safe for use on food crops. The researcher who conducted the study works for the pesticide company. What potential biases may have affected the study
1.3
1. Review- What are the themes in biology that come up again and again
Predict- Suppose you discover a new organism. What would you expect to see if you studied it under a microscope
2. Review- At what levels do biologists study life
Classify- A researcher studies why frogs are disappearing in the wild. What field of biology does the research fall
3. Practice- In an experiment, you need 250 grams of potting soil for each of 10 plant samples. How many kilograms of soil in total do you need?
2.1
1. Review- What is a compound
Apply Concepts- Water (H2O) and hydrogen peroxide (H2O2) both consists of hydrogen and oxygen atoms. Explain why they have different chemical and physical properties
2. Big Idea- Why do you think it is important that biologist have a good understanding of chemistry?
2.2
1. Review- What does it mean when a molecule is said to be “polar”
Use Models- Use the structure of a water molecule to explain why it is polar
2. Review- What is an acid What is a base
Explain- The acid hydrogen fluoride (HF) can be dissolved in pure water. Will the pH of the solution be greater or less than 7
3. Creative Writing- Suppose you are a writer for a natural history magazine for children. This month’s issue will feature insects. Write a paragraph explaining why some bugs such as the water strider can walk on water
2.3
1.Review- Name four groups of organic compounds found in living things
Explain- Describe at least one function of each group of organic compounds
Infer- Why are proteins considered polymers but lipids not
2.4
- What happens to chemical bonds during chemical reactions
- How do energy changes affect whether a chemical reaction will occur
- What role do enzymes play in living things and what affects their functions
2.Observe- What atoms constitute the compound above
