Reviewing Mitosis/Mitosis
There are technically two presentations in this collection of slides. The first presentation is a single-slide comparison of plant cell division and animal cell division. The second focuses on the steps of meiosis and the genetic...

Sexual Reproduction and Meiosis
In this biology worksheet, 9th graders label each of the diagrams representing the stages of meiosis. Then they describe how gametes vary from other cells in the body. Students also explain what happens during the process of fertilization.

Nonvascular and Simple Vascular Plants: Mosses to Ferns
Sometimes conservationists use specific plants to prevent erosion or fight invasive species. A 50-slide presentation covers both nonvascular and vascular plants. It discusses the plants, their stages and life cycles, reproduction, uses,...

Mitosis and Meiosis
Students model and differentiate between the processes of mitosis and meiosis. In partners, they use yarn and construction paper to create models for each of the phases of mitosis and meiosis then compare the chromosome numbers in each...
Curated OER
Flower Reproduction
Fifth graders examine the cycle of flower reproduction. They listen to a poem about a bee, observe and examine flowers in small groups, and develop a class KWL chart. Students then read about flower reproduction in their textbook, and...

Embryology as Evidence of Evolution
Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...
