This DIFFERENTIATED lab activity is a great chance for students to make a slide, practice microscope skills, and learn and reinforce other science content such as leaf structure, stomata, and homeostasis. Included are two versions of a leaf structure lab. One version is a more traditional lab, and the other is open-ended, or inquiry-based, and longer, allowing students to design their own experiment.

Both versions allow for hands-on examination, as well as reading and diagramming of the parts of a leaf, and understanding how the stomata help the leaf conduct photosynthesis and maintain homeostasis. In the second version, there is also an opportunity for students to design and conduct their own experiments related to stomata.

This product also includes suggested classroom uses, additional links, etc.

Materials needed (in addition to the leaf):

  • clear nail polish
  • clear tape
  • blank slide
  • microscope

After completing this activity, students will understand how stomata function and be able to identify the parts of a leaf.

to see state-specific standards (only available in the US).
Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis. Examples of investigations could include heart rate response to exercise, stomate response to moisture and temperature, and root development in response to water levels. Assessment does not include the cellular processes involved in the feedback mechanism.
Develop and use a model to describe the function of a cell as a whole and ways the parts of cells contribute to the function. Emphasis is on the cell functioning as a whole system and the primary role of identified parts of the cell, specifically the nucleus, chloroplasts, mitochondria, cell membrane, and cell wall. Assessment of organelle structure/function relationships is limited to the cell wall and cell membrane. Assessment of the function of the other organelles is limited to their relationship to the whole cell. Assessment does not include the biochemical function of cells or cell parts.
Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms. Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. Examples of evidence could include drought decreasing plant growth, fertilizer increasing plant growth, different varieties of plant seeds growing at different rates in different conditions, and fish growing larger in large ponds than they do in small ponds. Assessment does not include genetic mechanisms, gene regulation, or biochemical processes.
