Leaf Stomata as Bioindicators of Environmental Change
Students perform an experiment to determine the stomaltal index on the upper and lower epidermis of two species of leaves. Stomatal densities change in response to changing atmospheric levels of carbon dioxide and to annual rainfall.

Stomata: Microscopic Openings that Let Plants Breathe
Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

Leaf Stomata as Bioindicators of Environmental Change
Students, in this experiment, collect leaves from two species of trees and the stomatal index on the upper and lower epidermis of each leaf be determined.

Changing Planet: Withering Plants - Stressing Over Lost Water
Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...

Stomata
Students explore what the stoma does for a plant. In this botany lesson students complete a stomatal peel experiment and measure its densities.

Transportation in Plants
Young scholars investigate how plants transport water and nutrients through the plant. In this transportation in plants lesson plan, students use glass tubing, celery stalks, food coloring and leaves from plants to observe adhesion and...

Let's Learn About Lettuce
Students learn more about lettuce. In this agriculture lesson, students listen to their instructor lecture about the history of lettuce. Students then participate in an activity that requires them to compare and contrast iceberg lettuce...

Leaf Straw
Learners investigate plant structure and the process of photosynthesis. Using everyday items, they demonstrate that the leaves and stems of plants can act like a straw. In addition, they identify plant structure.

Let it Grow!
Students explain the relationship of plants and animals in the environment. They name the basic requirements for plant growth and define the terms photosynthesis, stomata, chlorophyll and xylem.
Curated OER
Photosynthesis: How do plants make food?
Students study why plants are green and how water is transported in them. They examine how plants respond to different amounts of light.
Curated OER
The Water Cycle
Students are introduced to the components and importance of the water cycle. They are shown how groundwater moves using a model. Students list 9 places on earth where water is found. They define the terms cycle and water cycle.

Desert Dynamics
Fourth graders examine the various types of plants and animals found in the deserts of Utah. In groups, they discover how the plants and animals have adapted to the harsh environment. To end the activity, they compare and contrast the...
