Meiosis and Genetics In this lab, students investigate how the events of meiosis relate to Mendelian genetics. View »
Sweet and Colorful Density Column In this activity, students determine the density of a variety of sugar solutions and layer them to form a density column. View »
Testing for Segregation of Alleles In this lab, students test corn pollen for evidence of the segregation of alleles. View »
Introduction to Drosophila: Phenotypes In this lab students compare phenotypes of mutant Drosophila to wild type. The activity is intended as a student’s first experience working with Drosophila. View »
Investigating a Phenotype In this activity, students investigate a phenotype that is not so conspicuous, and they perform a simple chemical test to reveal the underlying basis of the phenotype. View »
Three-Point Linkage with Drosophila In this lab students investigate the effects of gene linkage and crossing-over on the inheritance of three traits of Drosophila. They use the data they collect to construct a linkage map of the gene loci. View »
Two-Point Linkage with Drosophila In this lab students explore the genetic consequences of gene linkage using an F1 cross of Drosophila. View »
Dry Ice Explosion Demonstrate the physical states of carbon dioxide with the help of this video. View »
Freezing Point Depression Activity: Ice Cream Spring brings showers, sunshine, and the prospect of summer break. Celebrate with this cool, fun activity. It requires just a few inexpensive materials and can be the basis of an engaging lesson on colligative properties. View »
Nylon Synthesis Kit Demo Experience the Nylon Synthesis Kit Demo in this video! View »
Periodic Table Mystery P is less dense than S. S is an alkali metal. E is a noble gas. In this activity, students generate a periodic table from clues and predict the missing properties of several elements based on the elements’ locations in the table. View »
Petri Dish Electrolysis Activity Introduce your students to reduction-oxidation reactions and some of the basic terms of electrochemistry (such as electrode potential, anode, and cathode) with this activity—creating electrolysis in a petri dish. View »
Gene Interaction with Drosophila How do genes interact in the inheritance of traits? Find out in this intriguing study of the inheritance of eye color in Drosophila. View »
Genetics with Drosophila F1 Crosses Drosophila genetics labs without the the need to select virgin female flies for crosses. We ship F₁ flies so your students need only to set them up in fresh vials to produce an F₂. View »
Genetics with Drosophila F1 Crosses: Sex-Linkage Drosophila genetics labs without the the need to select virgin female flies for crosses. We ship F₁ flies so your students need only to set them up in fresh vials to produce an F₂. View »
Introductory Genetics with Drosophila Use this LabSheet with a variety of our Drosophila cultures and sets for introductory labs covering monohybrid, dihybrid, and sex-linked crosses. View »
Chemoween and Other Spooky Science Treat your students to some spirited demos and hands-on activities, and celebrate Halloween as the finale to your October science explorations. View »
The Lava Lamp Lab: A Guided-Inquiry Approach to Intermolecular Forces Remember that lava lamp you had? You and your students can use this lab to explore the fascinating world of intermolecular forces firsthand. View »
Teaching Chemistry with Manipulatives Manipulatives can help students (especially visual and tactile learners) understand abstract concepts by allowing them to “see” a chemical structure or process. We offer 2 ideas for creating manipulatives and how to use them. View »
Chemistry Holiday Hoopla! If the approaching holidays are causing student minds to wander, try these holiday-oriented demonstrations to recapture their attention. The activities acknowledge the season while helping students understand important chemistry concepts. View »
Easy Variation and Natural Selection Lessons with Wisconsin Fast Plants® Seed Disks Explore a technique that makes teaching variation and natural selection lessons with Fast Plants® easier than ever. In this activity, students examine the effects an abiotic environmental change (salinity) has on an experimental plot of Fast Plants®. Includes detailed background information and instructions. View »
Fractional Distillation of a Carbonated Soft Drink How is crude oil refined into many valuable products? Students can find out with this lab activity. Substituting a soft drink for crude oil, they use fractional distillation to separate the soft drink into its components, or fractions. View »
Carolina Quick Tips®: Paper Chromatography of Pens and Acid-Base Indicators In this activity, students use paper chromatography to separate the components of black ink in pens and of an acid-base indicator solu- tion. View »
In a Fog? Cloud Formation Use this activity to explore the reasons for cloud formation. View »
AP® Biology: Statistics Worksheet A set of 4 problems focused on statistics and analysis. View »
Evaluating a Scientific Claim: Evaluating Lemonade as a Buffer Students can use this graphic organizer to evaluate a scientific claim about adding buffers to medicines. View »
Wisconsin Fast Plants® Monohybrid Crosses Inquiry In this scientific inquiry activity, students germinate F2 generation Wisconsin Fast Plants® seeds and identify the phenotypes and possible genotypes of the F2 generation plants. View »
Introduction to Wisconsin Fast Plants® Phenotypes In this inquiry activity, students investigate phenotypes using Wisconsin Fast Plants® seeds. After the seeds germinate, students identify the phenotypes and the possible associated genotype. View »
Thermochemistry: An Endothermic Reaction In this thermochemistry demonstration, students observe an extreme, spontaneous endothermic reaction between 2 solid compounds, measure changes in temperature, and make observations. View »
Carbon Snake In this teacher-directed demonstration of an exothermic reaction, students observe the dehydration of a carbohydrate using concentrated sulfuric acid. View »
