Protists - The Protozoans
Five pages provide thorough coverage of three protozoans: euglena, amoebae, and paramecia. For each, junior biologists read factual text, label the organism, and write answers to several questions. This neatly organized assignment is...

Invisible Life
By setting up an aquarium in the classroom, learners are able to describe some macroscopic and microscopic organisms that are found inside. This well-designed, and educationally rich lesson requires pupils to use microscopes to view...
Curated OER
Find the Speed of a Protist
Students identify protists under a microscope, and using a stopwatch calculate the speed of a protist from a pond water sample. They use distance and time to identify the speed of a protist, and create a distance versus time graph to...

The Euglena
In this euglena worksheet, students read information about these unicellular organisms. Students then color in the different structures of the euglena on a diagram. Students complete 10 short answer questions.
Curated OER
Diffusion through Membranes
Students identify diffusion and its processes through experimentation and calculations. They also use a CBL and conductivity probe to measure the conductivity of various solutions and study the effect of concentration gradients on the...
Curated OER
Eutrophication Experiments
Observe two different water samples and write down observations. Write a paragraph which predicts the relative amounts of nutrients, nitrates, and phosphates in the water samples. Compare water samples under a microscope.
