In this analysis and discussion activity, students learn about basic coral biology.

Then, they find answers to their questions about coral bleaching.

This activity concludes with questions about how we can reduce coral bleaching and why we need to check sources for potential bias.

In this analysis and discussion activity, students investigate several examples of plants that have grown in odd shapes.

As students analyze these anchoring phenomena, they learn (1) how the zones of cell division and elongation contribute to the growth of stems and roots; (2) how the effects of a plant hormone on cell elongation contribute to plant responses to light and gravity; and (3) how differentiated cells (xylem cells, phloem cells and photosynthetic cells) cooperate to supply all parts of the plant with needed molecules and ions.

In this activity, students interpret data from scientific studies, develop and refine scientific models, and answer additional analysis and discussion questions.

This activity can be used in a unit on cells or as an activity on development after students learn about cell division.

This minds-on, analysis and discussion activity introduces students to basic cancer biology, somatic mutations, and regulation of the cell cycle.

Students view an introductory video about a teen with melanoma and then complete six sections: “What is melanoma?”, “How does a melanoma develop?”, “Why do melanoma cells divide too much?”, “Environment and inherited genes influence your risk of melanoma.”, “Different Types of Cancer”, and “Research Challenge”.

Concepts covered include cell cycle checkpoints, somatic mutations, and DNA repair enzymes

Students begin by comparing the characteristics of whales, mammals and fish to decide whether whales should be classified as mammals or fish. To support their conclusion, students make a scientific argument (claim, evidence, reasoning).

Students learn about the evolution of whales and other cetaceans by analyzing evidence from comparative anatomy, embryology, fossils, and DNA and proteins. Finally, students make a scientific argument for the claim that whales and other cetaceans evolved from land mammals.

In this hands-on, minds-on activity, students analyze the similarities and differences between bat and squirrel skeletons and between bat and insect wings.

Students learn about the two ways that evolution produces similarities: (1) inheritance from shared evolutionary ancestors (homologous characteristics) and (2) independent evolution of similar characteristics to accomplish the same function (analogous characteristics).

In the laboratory investigation, students observe the external anatomy and locomotion of earthworms, mealworms, and crickets. Students use these observations and the concepts they have learned to figure out which two of these animals are more closely related evolutionarily. (NGSS)
