what are we going to study the week of March 6 to march 17 , 2017
SCIENCE: describe the roles of organisms and the flow of energy within an ecosystem.
a. Identify the roles of producers, consumers, and decomposers in a community.
b. Demonstrate the flow of energy through a food web/food chain beginning with sunlight and including producers, consumers, and decomposers.
c. Predict how changes in the environment would affect a community (ecosystem) of organisms.
d. Predict effects on a population if some of the plants or animals in the community are scarce or if there are too many.
identify factors that affect the survival or extinction of organisms such as adaptation, variation of behaviors (hibernation) and external features (camouflage and protection).
a. Identify external features of organisms that allow them to survive or reproduce better than other organisms that do not have these features. (e.g. camouflage, use of hibernation, protection, etc.)
b. Identify factors that may have lead to the extinction of some organisms
ESSENTIAL QUESTIONS: THESE QUESTIONS ARE YOUR HOMEWORK. DUE FRIDAY, MARCH 13, 2017 FOR A GRADE.
1. What is necessary for life?
2. Are all organisms important?
3. Why is a food web called a food web?
4. Why do organisms become extinct?
5. What are the roles of the producers, consumers, and decomposers in the community?
6. How does the flow of energy go through a food chain? From where does this energy come?
7. How will changes in the environment affect a community of organisms?
7. How does the population affect the number of plants and animals in the community?
8. How do external features tell you about the ability of the animal to survive in the ecosystem?
9. Why do some animal become extinct? What role in a community so producers, consumers and decomposers play?
10. What makes an animal a consumer? What makes a plant are producer?
11. What do decomposers feed on?
12. How does a scarcity or abundance of plants and animals?
13. What causes plant and animal species to become endangered and extinct?
14. Why do all food chains and food webs start with the sun?
Plants and animals don’t need each other for survival. Adaptations and camouflage prevent some animals and plants from becoming food. Extinction only occurred in the days of dinosaurs. Plants and animals can change features to adapt.
Plants and animals do need each other to survive. All plants and animals will become food for something one day. Extinction still occurs today. Adaptations take a long time to occur.

30. MD.5 Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint and understand concepts of angle measurement.
31. MD. 5 Recognize that an angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fractions of the circular arch between the points where the two rays intersect the circle; an angle that turns through 1/360 of a circle is called a "one degree angle", and can be used to measure angles.
Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.
4.G.A.1 Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
- I know a figure is symmetric when it can be divided by at least one line into two congruent parts where the two parts are mirror images of one another.
- I know a line of symmetry is a line on which a figure can be folded so the two parts match exactly.
- I know a figure can have more than one line of symmetry.
- I know a figure with at least one line of symmetry is symmetric.
- I can categorize two-dimensional figures as line-symmetric and non-line-symmetric.
- I can draw in the line(s) of symmetry for line-symmetric shapes.
- I can explain why a given shape is non-line-symmetric.
How do you recognize a line of symmetry? Are all two-dimensional figures symmetric? Justify your answer.
A line of symmetry divides a shape into two congruent parts. A figure can have one line of symmetry, more than one line of symmetry or none at all.
BE A DISTINGUISHED LEARNER
Draws, defines, and interprets points, lines, line segments, rays, angles, and parallel and perpendicular lines and represents them in two-dimensional shapes; classifies two-dimensional figures based on the presence or absence of geometric characteristics; identifies and generalizes right triangles; interprets symmetry as a characteristic of two-dimensional shapes; and provides non-examples of two-dimensional shapes, given specific characteristics.
Line of symmetry is a line that divides a figure into two congruent parts, each of which is the mirror images of the other.
When the figure having a line of symmetry is folded along the line of symmetry, the two parts should coincide.
