Q1: Each circle in this food web is a different organism Q1: Each circle in this food web is a different organism. Which organisms are the decomposers? 7 only 5 and 6 only 2, 3, and 4 only D. There are no decomposers. SC8.3.3.b DOK 2

Q2: One tank of goldfish is fed the normal amount, which is once a day Q2: One tank of goldfish is fed the normal amount, which is once a day. A second tank is fed twice a day, and a third tank is fed three times a day for six weeks. The body fat of each fish is recorded daily. What is the control? the body fat of each fish B. the temperature of the water C. the tank of fish fed once a day D. the tanks of fish fed more than once a day S.C.8.1.1.c DOK 3

Mathematics Booster If a giraffe is 6 meters tall and the scientists studying the giraffe are 2 meters tall, how many scientists would it take to equal the height of the giraffe? Point out the area for showing their work and for their answers. Also have students reflect upon their correctness and what they can do in the future when facing a similar problem.

Greek and Latin Roots Greek/Latin Meaning funct- perform hema(o)- blood -itis inflamed condition bi- two, double cardi- heart Have students write the meaning of each root in the appropriate spot in their BLAM books. We’ll work with this set of roots, using strategies from Marzano’s Six Step Vocabulary, for two weeks. Then we’ll have another set of roots.

Objectives I will know (knowledge): I will be able to (skill): What cells are. I will be able to (skill): Describe how scientists first observed cells and developed the cell theory. Describe how microscopes produce magnified images.

Bell Work Why is a microscope needed in order to study cells? Answers:

A1: Each circle in this food web is a different organism A1: Each circle in this food web is a different organism. Which organisms are the decomposers? A. 7 only This would be a tertiary consumer. These consumers eat the secondary consumers. B. 5 and 6 only This would be a secondary consumer. These consumers eat the primary consumers. C. 2, 3, and 4 only These consumers are the first organisms to eat the producers. These are the primary consumers. D. There are no decomposers. The diagram shows producers and different levels of consumers, but does not show decomposers. SC8.3.3.b DOK 2

A2: One tank of goldfish is fed the normal amount, which is once a day A2: One tank of goldfish is fed the normal amount, which is once a day. A second tank is fed twice a day, and a third tank is fed three times a day for six weeks. The body fat of each fish is recorded daily. What is the control? the body fat of each fish B. the temperature of the water C. the tank of fish fed once a day D. the tanks of fish fed more than once a day S.C.8.1.1.c DOK 3

Mathematics Booster If a giraffe is 6 meters tall and the scientists studying the giraffe are 2 meters tall, how many scientists would it take to equal the height of the giraffe? 6 meters ÷ 2 meters per scientist = 3 scientists
