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.

investigating and Modeling Sea Urchin Fertilization and Development
High schoolers begin by using clay to model fertilization and early development of sea urchins and chordates. They move on to mixing live sea urchin sperm and ova together to observe, diagram and record events occurring in fertilization...

Parts of a Flower! Flower Dissection
Sometimes the best way to learn about plants is to see the different parts of a plant yourself. Groups of learners dissect flowers to answer questions about what they observe and what they wonder about their flower.

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...
Curated OER
Parts of the Flower
In this biology worksheet, students examine a diagram of a flower and read a selection that describes all of the parts including the petals, the stamen, the anther, and the sepals. They answer 11 on-line fill in the blank questions using...

Embryology as Evidence of Evolution
Learners 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...

Flower Basics
Learn about plants and pollination with a worksheet about the parts of a flower. After labeling the anatomy of a flower using a word bank, kids explain the difference between self-pollination and cross-pollination, and unscramble...
Curated OER
Meiosis, Gene Linkage and Maps
Students identify the structures that actually assort independently. They are taught how gene maps are produced. Students compare the processes of mitosis and meiosis. They are shown their (mitosis and meiosis) significane to sexual...
