At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Ever been told you have your father's eyes? How did it happen? Young biologists get a hands-on experience in meiotic gene expression with a fun pairs-based activity. Participants use pipe cleaner chromosomes with trait beads to make...

Begin looking at reproduction by contrasting sexual reproduction with asexual reproduction. Sexual reproduction gives us genetic variation as meiosis creates brand new chromosomes through cross over. Male and female anatomy is covered,...

Welcome to the complex biological story that is our life. Great visual imagery zooms in on the dissection of a DNA double helix in our body. What happens with RNA? Where do amino acids come in? This resource explores our inner workings...

Aren't mitosis and meiosis the same thing? A helpful flow chart demonstrates the difference between mitosis and meiosis on Paul Andersen's Smart Board. Time lapse videos include show mitosis and cytokinesis.

The development of the male and female gametes in a plant is illustrated, explaining plant fertilization, pollination, and reproduction. Overall, get a complete picture of the life cycle of a flowering plant with some wonderful details...

If humans share over 99% of the same chromosomes, how are we different? There are 10 million SNPs in the human genome, accounting for most of our genetic differences. Watch this short clip to introduce your learners to SNPs, or single...

The lecturer starts by emphasizing that the mitotic process is a separate mechanism to cytokinesis - the cytoplasm splitting to become 2 cells. The video continues explaining the stages of mitosis in great detail. Each stage is...

Imagine a pair of dragons that produce offspring. What percentage of the hatchlings have wings and large antlers? An engaging activity draws genetics learners in, introduces them to alleles, meiosis, phenotypes, genotypes, and teaches...

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...

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....

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...

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...

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...

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...

Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both...

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...

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....

Fill- in-the-blank, labeling, and short answer questions make up this well-written cell division worksheet. Neat diagrams of chromosomes and dividing cells are included. Junior biologists show what they know about reproduction, meiosis,...

New ReviewFrom crime to paternity, DNA fingerprinting has revolutionized how the world views inherited traits. Science sleuths investigate the facts about DNA profiling through a variety of activities. The Teacher's Guide includes printable...

New ReviewWhat's your type? Genetically speaking, of course! Immerse your class in the world of karyotypes through an insightful activity from the K20 Center. Scholars take on the role of genetic counselors to determine the karyotype of offspring...

Mutations are not just deformed creatures we see in movies—they happen every day! Scholars study the different types of genetic mutations in the 12th installment of a series of 18 lessons. A creative activity uses candy and other food...

What do cats and human DNA have in common? The second instructional activity of a series focuses on the mapping of mammal genomes. Scholars learn about the structure of DNA as they compare the chromosomes of humans and felines.
