Sexual Reproduction and Meiosis
In this biology instructional activity, 9th graders create one chromosome using a red plasticine and another using blue plasticine. Then they illustrate different ways of crossing over, including double crossovers. Students also explain...

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.
Curated OER
Interactive Meiosis
Students study meiosis and the stages of mitosis. In this meiosis lesson plan students divide into groups and complete an activity.

Mitosis, Meiosis and Fertilization Vocabulary Review Taboo Game
Can you describe a gamete without using the words sperm or egg? Scholars play a vocabulary review game where they try to get other players to guess their words. Each card has the target word as well as two related words they must not...
Cold Spring Harbor Laboratory
Genes Get Shuffled When Chromosomes Exchange Pieces
Some genes link to others that have implications for inheritance. A set of resources lead pupils through the history of this discovery. They explain how chromosomes recombine and which parts are more susceptible to this linkage....

KARYOTYPE ALTERNATIVES
Students comprehend that karyotyping is a process in which chromosomes are cut from an enlarged picture and arranged in decreasing order of size. The cells to be viewed are first chemically treated to increase the number of dividing...
Curated OER
Biology Midterm Review
In this biology worksheet, 9th graders identify and locate various vocabulary terms pertaining to the study of biology. There are 50 biology terms located in the word search.
Curated OER
Mitosis vs. Meiosis
In this cell division learning exercise, students compare and contrast the processes of mitosis and meiosis. Students complete 9 questions in a chart.
Curated OER
Karyotype Puzzle
Students identify chromosome pairs based upon band patterns and location of centromere. They order chromosome pairs based upon size. Students differentiate normal karyotypes from abnormal karyotypes. They correctly record karyotype...
Curated OER
Cell Growth and Division
For this biology worksheet, 9th graders label the diagrams with the appropriate phase of mitosis illustrated. Then they explain why skin cell undergo mitosis continuously. Students also explain why mitosis is a form of asexual reproduction.

Raven Chapter 11 Guided Notes: How Cells Divide
Take your advanced biology learners across the great divide: where cells divide, that is! Although it was created as a chapter reading guide, having your class complete this learning exercise is not only appropriate, but also highly...

Evidence of Evolution by Natural Selection
Being able to test a hypothesis is a scientific must. AP Biology pupils can see the process of hypothesis testing through evidence for evolution as seen in natural selection. Slides contain solid information and excerpts from academic...

Evidence of Evolution by Natural Selection: Testable Hypotheses #2
These slides will activate prior knowledge with real-life examples of natural selection. The predictions and outcomes for those examples are explained. Your students will like the information about the relevant chromosome tests that can...
Curated OER
Cell, Socks, and Sex
Donate old socks for science! Young biologists model mitosis and meiosis, using socks as chromosomes and a balloon as a nucleus. This ingenious idea for modeling cell division will be more memorable to your young biologists than any set...
Curated OER
Mitosis and Cell Division
Students discover the processes that occur during mitosis and what makes each phase different and distinct from the others as well as how each contribute to the overall process of mitosis by looking at onion root tips under a microscope.
Biology Junction
Meiosis: Gamete Production
Sex sells, or in this case, sex cells allow reproduction to occur. Scholars view a presentation and animation as well as complete a worksheet on meiosis and gamete production. They observe every stage and learn about the function and...
Biology Junction
Cellular Division
Based on current scientific knowledge, all cells come from preexisting cells. Scholars learn about cell division, cell replication, mitosis, meiosis, and more with a PowerPoint. It describes the differences between prokaryotes and...
Curated OER
Mitosis And the Cell Cycle
Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.
Curated OER
Study Guide for Chapter 12: The Cell Cycle
In this biology worksheet students map out and describe the process of mitosis for the nine questions. The last four questions are several combined in each.
Curated OER
Meiosis
Students study meiosis and how it leads to variation. In this genetic reproduction lesson students complete a lab activity that calculates different genetic possibilities.

Modeling Mitosis and Meiosis
Learners construct and manipulate models of mitosis and meiosis and compare/contrast them. They create the models using index cards and yarn, interpret diagrams and photographs, and summarize written descriptions.
