Carnivorous Plants

What do you think of when you hear the term carnivorous plant? Does it conjure up images of man-eating plants deep within a tropical jungle, perhaps science experiments gone bad, or even Audrey II from the 1960 movie, The Little Shop of Horrors?

Multimeter is used to measure an electric current.

Dollar Store Single Function Signal Generator

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.

An acid-base titration

Titrations: Techniques and Calculations

A titration is one of the most common quantitative lab techniques for determining the concentration of an unknown chemical. The power of the process is its simplicity, as there is a visual indication, a color change, that allows the reaction process to be monitored and the amounts of reactants measured.

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.

Computer rendering of a protein showing the secondary structure consisting of alpha helix and beta sheets. Tertiary and Quaternary structure is also shown.


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.
