In this activity, students use a solar-powered model, such as the dancing flowers often sold at discount variety stores. They carefully disassemble the plastic housing and attach a sensor to the capacitor, then use probe ware to graph the voltage across the capacitor.

Ecology: Ecosystem Sustainability

Carolina has everything you need to teach ecology. Ecology is the foundational study of how organisms interact with each other and the planet.  A complete study of ecology may include investigating the biotic and abiotic factors of biomes, the structures of ecosystems, the processes at work within ecosystems, interactions among species in an ecosystem, and ecosystem sustainability. This complex topic is broken down into three sections: ecosystem structure, ecosystem interactions, and ecosystem sustainability.

Closing Up the Lab

At year’s end, you have a lot to do in a short amount of time. We hope this checklist will help as you close down your laboratory and get it in shape for the start of the next school year.

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.

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.

Anatomy and Physiology: Human Organs

Take a deeper dive into the anatomy and physiology of specific organs and structures within the human body. Use our student-ready infographics to introduce each key body part. Encourage students to apply their knowledge of each system by investigating health-focused case studies related to each structure.

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.

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.
