Photosynthesis
Carolina has everything you need to teach photosynthesis. Understanding this concept sets the foundation for many other biological concepts.
Acid-Base Indicators
This introduction to acid-base indicators includes a helpful table of Carolina’s indicator ranges, the pH values of common household acids and bases, plus a fun invisible ink demonstration that you and your students will enjoy.
Biochemistry
Carolina has everything you need to teach biochemistry. Biochemistry is the foundation for all biology concepts. Basic elements combine into the macromolecules that make life processes possible. This guide breaks down the important information students need to know, provides links to products and free digital resources, and includes suggestions for hands-on-labs that reinforce student learning. We have gathered a variety of products and resources to better help you teach this concept.
Signs of Chemical Changes: Testing for CO2, O2, and H2
When chemistry or physical science students initially learn about chemical changes and chemical reactions, they are taught to look for evidence of the change or reaction. Chemical changes, or reactions, are the result of breaking bonds in the starting substances, called reactants, and the rearrangement of those substances and bonds to make new substances, called products. The […]
Mitosis and Meiosis
Carolina has everything you need to teach mitosis and meiosis. The processes of mitosis and meiosis are fundamental topics in biology. During these lessons, students learn how cells divide and pass along genetic information to new daughter cells. This knowledge is important as students advance their learning in genetics, inheritance, and diversity. However, the concepts can be difficult for students to understand because they aren’t commonly viewed processes.
Superworms and Darkling Beetles
Superworms and darkling beetles are great tools for the classroom. With the right care, these insects can help students observe numerous biological concepts in action.
Examples of Chemical Change
By exploring the basics of this topic, students will build an understanding of the molecules that make up the world around them. In this article, we will provide you with the basics on the topic, as well as examples of chemical change that you can share with your class.ÂÂ
Synthetic Blood
Carolina® Synthetic Blood has several advantages over other suppliers’ products, which usually depend on chemical reactions producing insoluble salts that precipitate from solutions. These products do not give visually realistic results. In actual blood typing, red blood cells form clumps (the agglutination reaction) that separate from the blood plasma. When mixed the appropriate synthetic antiserum, Carolina® Synthetic Blood forms clumps in the same way, for a realistic blood typing result. It’s the closest to authentic blood typing that you can get without using real blood.
Need for Speed
Imagine a world without enzymes. Bread wouldn’t rise. Seeds wouldn’t sprout. Your tasty lunch wouldn’t digest; it would sit in your stomach for weeks … EXACTLY! Life is not possible without enzymes. ALL reactions and processes within an organism depend on enzyme activity. The challenge is helping students understand that enzymes are essential in order […]
Fermentation by Yeast
A study of fermentation by yeast is an interesting extension of AP* Biology Lab 5 Cell Respiration. It also offers possible tie-ins to Lab 1 Diffusion and Osmosis and Lab 2 Enzyme Catalysis. In this activity, students measure the rate at which yeast ferments solutions of differing sucrose concentrations and apply the results to common […]
