  • Under the Skin—Mammalian Musculature Whether you’re teaching college-level anatomy and physiology, an advanced high school anatomy course, or a basic biology course, cat dissection is one of the best ways to help your students understand mammalian musculature. View »
  • Flex and Extend: Modeling a Human Hand Lead students in an engaging and creative project where they build a model that demonstrates the flexing action of the human hand. As students learn about the tendons and muscles of their own hands, they are prepared for a discussion about the similarities and differences between a biological hand and their model. View »
  • Introduction to Photosynthesis Using Coleus Plants The simple exercises that students perform in this lab demonstrate that plants produce glucose through photosynthesis, that plants convert at least some of the glucose to starch, and that sunlight is a critical factor in photosynthesis. View »
  • Epigenetics II: DNA Methylation in Arabidopsis In Arabidopsis, a popular model organism for plant biologists, the homeotic gene Flowering Wageningen (FWA) controls flowering time. In the growing plant, DNA methylation silences both copies of the FWA gene, allowing the switch from vegetative growth to flowering. Read about epigenetic modifications and how to test for chemical changes to DNA that act as a developmental regulator in plants. View »
  • Central Dogma of Biology (DNALC Video) Replication, transcription, and translation are the three major processes that comprise the central dogma for molecular biology. This 3D animation demonstrates those steps as you visualize how the DNA genetic “code” leads to proteins that help us develop and function. View »
  • Epigenetics I: Using Carolina Corn Ears to Teach Genetic Imprinting Corn, or maize, is a wonderful model for genetic studies. Carolina Indian corn, with brightly colored kernels, makes it easy for your students to learn about the inheritance of the anthocyanin pigment gene. Students learn how to predict phenotype from genotype but may be surprised at the results—because of genetic imprinting. View »
  • Glycerinated Muscle Activity Carolina’s ATP Muscle Kit allows students not only to observe muscle structure but also to experiment with different solutions that make the muscle contract. View »
  • Seedling Genetics (Soybean or Tomato) From a study of either soybean seedlings or tomato seedlings, students determine that the color alleles involved exhibit incomplete dominance, that the seedlings are segregating in a ratio of 1 green:2 yellow-green:1 yellow, and that the parent plant was yellow-green and heterozygous.

  • mRNA Translation (DNALC Video) Witness the molecular choreography of messenger RNA (mRNA) as it goes through the steps needed to produce a key biological protein, hemoglobin. Introduce your students to important biological molecules like mRNA, tRNA, amino acides, ribosomes, and more during this 3D animation. View »
  • Culturing Algae Determine the best storage and growth parameters for your algae with this care booklet. View »
  • The Science of Fear You know that hair-raising feeling you get when you’re scared? By undergoing a specific physiological response, your body is primed to confront, and hopefully overcome, whatever scary situation you face. View »
  • Hydroponic Nutrient Solution After a structured investigation of a hydroponic technology, students design an experiment to test different nutrient solutions. View »
