How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Learners are introduced to Gaia theory of natural homeostasis. They graph Earth's temperatures over time, construct terrariums or monitor the outdoor environment. Related videos titles are suggested, but may be outdated. The objectives...

Students use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little meaning to...

An exciting activity has scholars use cell parts to build bacteria through cooperation with other groups. Each group has some of the cell parts needed, but they must trade with other groups to be able to fulfill their function as a...

Students explore the evolution and features of bacteria through a series of activities. In this biology lesson, students collect data and graph bacterial growth. They design a brochure about bacteria's role in society.

Students relate the number and length of generations in their living family members to the number of generations that have passed since specific events in recorded history. They then apply this time conceptualization to the number of...

Students examine the three domains of life and explain that all living things share a common ancestor.  In this paleontology lesson students are introduced to the process of illustrating evolutionary relationships. 

Students explore the classification system of organisms: taxonomy. They examine prepared slides of Protozoans and record information on a Taxonomy Recording Sheet. Two additional classifying activities are also included in this lesson.

Students study chloroplasts, their structure and evolution.  In this photosynthesis lesson students experiment with polarized light and the production of chlorophyll.
