Plan and conduct an investigation to determine if plants need sunlight and water to grow. [Assessment Boundary: Assessment is limited to testing one variable at a time.]

● 2-LS2-2

Develop a simple model that mimics the function of an animal in dispersing seeds or pollinating plants.*

LS2.A: Interdependent Relationships in Ecosystems ● Plants depend on water and light to grow.

LS2.A: Interdependent Relationships in Ecosystems Plants depend on animals for pollination or to move their seeds around.

ETS1.B: Developing Possible Solutions Designs can be conveyed through sketches, drawings, or physical models. These representations are useful in communicating ideas for a problem’s solutions to other people.

Science and Engineering Practices

1. Asking questions (for science) and defining problems (for engineering)

2. Developing and using models

3. Planning and carrying out investigations.

4. Analyzing and interpreting data

5. Using mathematics and computational thinking

6. Constructing explanations (for science) and designing solutions (for engineering)

7. Engaging in argument from evidence

8. Obtaining, evaluating, and communicating information

Cross Cutting Concepts

Cause and Effect

Structure and Function

1.Do marigolds need water and sunlight to survive?

2.What characteristics does a bee have to be able to pollinate a flower?

3.Why do bees pollinate flowers and why is it important? 4.How do plants thrive in different conditions?

● Pollination ● Characteristics ● Ecosystems

● Disbursement

2. Compare the liveliness of the plants and how plants thrive in different conditions. 3.Describe the cause and effect of when a plant gets the sunlight and water it needs versus when it doesn't.

4. Use a model to demonstrate how bees pollinate flowers so that more flowers will grow.

5. Support a variety of ways that pollination is important for ecosystems. 6.Defend how the structure of the bee allows for the function of pollination and the disbursement of seeds.

2.I will observe each group using their models to observe what characteristics make it possible for a bee to pollinate. Each student will turn in an exit ticket and respond to the question, “After experimenting with your model, explain what characteristics a bee needs to have in order to pollinate a flower.

3.For students who choose to do the poster, they will be graded on images, and information on their poster as well as collaboration. The students who do a commercial will be graded on the accuracy of the facts and participation in making the commercial.
