University of Hamburg: C3, C4, and Cam. Regulation of the Activity of Photosynthesis

Learners conduct experiments with plants.  In this photosynthesis lesson plan, students examine plants under different types of lights.  They calculate the amount of dissolved ocygen concentration and compare it to the formula...

It's not often that you come across a clever laboratory activity that is both imaginative and comprehensive! Using M&M's and Reese's peanut butter candies to represent two different clam species, young biologists test for "relative...

Gummy bears are tasty, but did you know they are also used to determine color and light properties? Use the activity as a way to demonstrate light absorption, light reflection, and refraction with high schooler....

It's hot today, but is that the weather or the climate? This colorful presentation isolates both concepts to allow for better understanding by covering the positioning of the planet, making comparisons of land versus water, and looking...

Get some laparoscopic training without the pain with an activity that challenges class members to find out what it is like to perform laparoscopic surgery. Teams perform three different tasks and quantify their performance. The...

Here is an unusual comparison: the swimming conditions of a sperm cell and a sperm whale. Introduce your physics class to the Reynolds number by sharing this video comparison during your fluid mechanics unit. Afterward, teach them to...

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

Scientists have yet to find the limit on the human brain's capacity for memory storage, so the potential is limitless!  An animated video demonstrates how the brain places information in short-term memory. Viewers observe the...

Take a ride on the carbon cycle by watching this animated featurette. Those who do will learn about the element carbon, how it cycles through the atmosphere and biosphere, and how it contributes to Earth's temperature. This video comes...

When was the last time your class saw a catalyst in action? Chemistry scholars observe an activated complex during an engaging experiment. Through both color change and evolution of a gas, individuals gain insight into the...
