An animated cell goes through the process of mitosis as DNA coils and bunches into chromosomes. As the nuclear membranes dissolve, spindles pull chromatids to opposite sides and stretch the cell. The video ends as mitosis ends: with two new cells.
Models of chromosomes are moved around on a table as a teacher describes mitosis in its separate phases. If you need a demonstration for your biology class, you can use this video.
In a sweet simulation, junior geneticists examine the chromosomes of a fictitious Reebop marshmallow animal, combine chromosomes to produce offspring, and then make a model of the resulting Reebop baby. Phenotypes include number of antennae, nose color, number of body segments, leg color, and more! The activity even addresses X and Y chromosomes for the baby's gender. This memorable activity reinforces concepts of heredity and gives teens practice in using genetics language. 
Investigate the ins and outs of cell division with this comprehensive set of activities. Detailed instructions for six different activities and your choice of eight different creative assessments can be found within this resource. By completing these lessons, your young biologists will have a well-rounded understanding of mitosis and meiosis. 
The 2005 version of the Regents High School Examination in the area of ecology is as comprehensive as previous years' exams. It consists of 40 multiple choice questions on everything from the structure of DNA to the interactions within an ecosystem. Questions following include analysis of population graphs, interpreting data, drawing a graph, and short essay responses. The same range of topics is covered. 
Junior geneticists tally eye color and height in their lab groups. They examine certain traits in soybean and corn seedlings. For each activity, they gather data and learn about continuous and discontinuous genetic variation. In another activity, pupils analyze pedigree charts. High schoolers really enjoy comparing their traits to others, so these activities will prove to be a hit with them. Because the lesson plans are so well written, they will be a hit with teachers as well!
Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple choice, graph interpretation, and essay analysys questions, 73 of them in all. Topics range from cell structure and function to population ecology. This exam blows others away with the variety included!
The living environment, from the interior of a cell to the complex relationships among populations, are queried in this final examination. Learners look at air pollution maps, diagrams of cells, population graphs, and drawing of cells. They answer multiple choice, graphing, and written response style questions. This is truly an all-encompassing assessment!
Learners create models of DNA and RNA using string and beads. They use beads representing the four nitrogenous bases of DNA to create a portion of a strand of DNA, and it's corresponding RNA. Then, students examine how many of their strands it would take to represent and actual strand of DNA and the number of bases it has.
Tne New York Regents High School Examinations are comprehensive and include various styles of questions, includingmultiple choice and the analysis of graphs. This particular version, the 2008 Living Environment exam surveys a variety of topics. Not only do test takers answer questions about populations and habitats, they also show what they know about genetics, cell structure, cell transport, DNA, and protein synthesis. 
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 valuable in enhancing their understanding of prokaryote cell division and mitosis. Such is the detail of this learning exercise, that even in seven pages no coverage of meiosis included. Colorful diagrams and photos are incorporated into the 31 labeling and short answer questions.
Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year course on the living environment. You will find 42 mulitple choice questions, as well as chart completion, diagram analysis, and written response to reading. This and other Regents examinations are ideal practice for AP tests.
Young biologists define reproduction vocabulary terms, answer critical-thinking questions, label a diagram of the human life cycle, and complete a chart comparing mitosis to meiosis. This is a well-balanced worksheet. Even though it addresses a specific textbook chapter, you will most likely cover identical material no matter which biology text you choose to use.
Discuss an article about families affected by genetic disorders and their decisions about whether or not to evaluate their own genetic information. Investigate four different inherited disorders. Participate in a probability exercise. Thoroughly written, this lesson plan exposes learners to real-life situations and stimulates poignant conversation. Links to articles, worksheets, and extension activities are all included leaving you well-prepared to teach on this topic.
For this meiosis worksheet, students read about the phases of meiosis I and meiosis II and simulate the chromosomes and chromatids in each phase. Students draw the changes in each phase and produce 4 cells with half the DNA in the end.
This mitosis worksheet targets AP-level biology courses. Learners identify the roles of kinase, cyclin, and CDKs, as well as describing external signals for growth. Large and colorful diagrams are displayed within the worksheet for students to label. 
Four comprehensive presentations on DNA and RNA are rolled into this resource! The subtopics include DNA and RNA, chromosomes and DNA replication, RNA and protein synthesis, and mutations. Throughout the 101 slides, you will find illustrative diagrams, links to outstanding animations, assessment questions, and hands-on activities. Wow! You will absolutely want to make use of this top-notch PowerPoint in your biology or genetics class!
Dive down to Bikini Bottom for a fantastic lesson on heredity! High school scientists make phenotype predictions for various characters based on given dominant and recessive traits. Use the PowerPoint here to review this concept before splitting learners into small groups. They experiment with probability using a coin toss, organizing findings on a worksheet (linked). Next, they conduct a virtual lab to practice completing Punnett Squares and explore another interactive site with a quiz. Synthesize their skills with two Sponge Bob worksheets which, after completed by all groups, can be presented in a jigsaw fashion. Use the final quiz here as assessment.
A single-paged set of instructions and grading system for a mitosis project are laid out for your life science learners. (Note that the page is repeated, making this a two-page document.) Pairs of beginning biologists use clay to model the steps of cell division, taking a photograph of each, and then combining them into a claymation video. Instructions refer to Microsoft's Photo Story software, which is available via a free download, but you could also have groups also use a slide show format for presenting their project.
This PowerPoint jumps right into the details of unusual traits and how they are coded.  The epistasis patterns in Labradors are used as a main example, and many instances of polygenic inheritance malfunctions are explained. All of this should grab your students' attention!
