Cells: A First-Hand View
In the first of two activities, your charges prepare wet mount slides of cork and bean sprout cells in imitation of Robert Hooke's historical investigation. An excerpt from his notes is included. Then, investigators compare animal cells...
Curated OER
Catalysts and Enzymes
Biochemists experiment with the oxothermic decomposition of hydrogen dioxide by adding manganese dioxide. They observe how pepsin enhances the action of acid on the digestion of egg white proteins. They use yeast to make bread rise. All...
Curated OER
Prokaryotes and Eukaryotes
Examine cyanobacteria cells as an example of prokaryotes and several other alga as examples of eukaryotes. Future biologists compare the two and notice the absence of nuclei in prokaryotes. These are classic activities for this purpose,...
Curated OER
Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...

Respiratory System Model
The procedure for constructing a working model of the respiratory system is revealed in this resource. A wonderful approach would be to have biology learners work in pairs to create a model and write the suggested paragraph explaining...
Curated OER
Light and Starch Production in Photosynthesis
Students are given the unique opportunity to see the contrast between parts of a leaf that have photosynthesized and parts of the leaf that have not. This visual image helps students see the results of this biological process. At the...
Curated OER
Microbiology Lab Safety
In this biology worksheet, students are introduced to the practices of safety as related to using a laboratory and then answer some questions as an assessment.
Curated OER
From Gene to Protein Study Guide
In this biology worksheet, students review and answer different questions based upon the molecules of DNA and RNA. They look at the specific protein order of the DNA strand and its synthesis.
Curated OER
Your Five Senses
Students identify the five senses. In this biology instructional activity, students participate in an experiment and use their five senses to identify various substances.
Curated OER
Eyes On Me
Students investigate the human eye. In this biology lesson, students read the book Look At Your Eyes and locate the various parts of their eye. Students play the game "I Spy."
