Substitute Plans
It’s that time of year again when you’re asked to provide lesson plans for a substitute who may or may not have a science background. Keep your students engaged in science with activities that are safe and easy for a substitute to manage. Make it Phenomenal! Use our Phenomena Video Gallery to get students questioning […]
Caring for Classroom Critters Over Breaks
It’s the end of the school year and your classroom is filled with critters in your aquarium, terrarium, or petri dishes. What do you do with them over summer break?
General Rules for Chemical Storage
First, identify any specific requirements regarding the storage of chemicals from: local, state, and federal regulations insurance carriers To help facilitate safe chemical storage, many Carolina chemical bottles have color-coded caps . The cap color indicates the appropriate storage setting making it easy to visually spot a misplaced chemical and to locate the chemical group […]
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?
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.
Marine Science
Marine science is one of the most popular science electives in high school and college. Its interdisciplinary structure requires students to integrate biology, chemistry, earth science, and physics making it a perfect addition to any science course sequence. 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.
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.
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.
The Whys and Hows of Writing a Lab Report
This author provides an excellent student lab-report format, explains how it adapts to different science disciplines, and suggests simple labs to familiarize students with it.
