Plants Grade 3-4
General Focus - Plant external structures and their functions related to photosynthesis
1) Why do plants look the way they do?
| Goals |
Outcomes |
| Identify the structures of a plant their functions. |
Leaves = take in sunlight and carbon dioxide.
Roots = take in water
Stems = transport water to the leaves.
|
| Identify that plants need sunlight, water and carbon dioxide to make food. |
Plants need water, sun and carbon dioxide to make food. |
| Predict how the functions of multiple structures. |
Different leaf structures collect more sunlight then others, different root structures work for different environments |
2) How do we know that plants make food?
| Goals |
Outcomes |
| Develop a definition of what food is for plants. |
Food for plants are starches.
|
| Identify where in the plant food can be found. |
Roots and Leaves |
3) Can plants survive without water and sunlight?
| Goals |
Outcomes |
Develop and test an hypothesis about the needs plants have to make food.
|
Ex. Plants cannot survive just with sun. |
| Support their hypothesis from data they collected in their experiment. |
Ex. Plants only need sunlight to survi |
4) Do plants eat?
| Goals |
Outcomes |
| Students will test out predictions about how leaves, stems and roots affect the amount of food produced. |
Not all options for leaves, stems and roots are good for all conditions. |
| Students will explain the relationship between sunlight, carbon dioxide, water and food production in plants. |
Plants need all three sunlight, carbon dioxide and water to produce food. |
| Students will explain that plants don't eat, they make their own food. |
Plants don't actually eat, they make their own food called starch. |
Plants Grade 5-6
General Focus - Ways plants obtain the materials to make their own food. (Internal structures)
1) How do plants make their food? (plant game)
2) Why do plants have stems, roots and leaves?
| Goals |
Outcomes |
Make observations about the leaves and roots of a plant.
|
Leaves are green and have lines running down them. On the bottom side of a leaf are small little holes.
Roots long and thin and are white or brown. They get smaller at the ends and sometimes have tiny little hairs on the roots.
|
Identify all the structures that help the plant obtain water, sunlight and carbon dioxide.
|
Leaves - sunlight and carbon dioxide
Roots - water and carbon dioxide
|
Explain how the various structures obtain water, sunlight and carbon dioxide.
|
Leaves have chloroplasts that contain chlorophyll that absorb sunlight.
Leaves have stomata that are small openings where carbon dioxide enters.
Roots have tiny hairs that absorb water and carbon dioxide in the soil. |
Explain what happens when plants are exposed to unlimited amounts of carbon dioxide.
|
Not sure - need to see this experiment

3) Why are plants green?

Leaves have stomata that are small openings where carbon dioxide enters.
Roots have tiny hairs that absorb water and carbon dioxide in the soil.
