Brine Shrimp Feeding
Third graders study the diet of the brine shrimp. This is an introduction to a math measurement of a micrometer because of the size of the food brine shrimp feed upon. They make predictions about the types of food shrimp eat based on...

Linear Motion in Class Test Review
In this linear motion worksheet, students answer 21 questions about acceleration, velocity, position and time. Students interpret graphs of position vs. time, velocity vs. time and acceleration vs. time. They calculate speed of objects,...
Curated OER
The Microscope and Cell
In this science worksheet, students calculate the size of different samples using the microscope as part of a formal lab assignment.
Curated OER
Oil Molecule
Nanotechnology is described for emerging engineers. Instructions for converting nanometers to meters is provided. Finally, the step-by-step laboratory procedure for measuring the size of an oil molecule is walked through. What a terrific...
Curated OER
Create a Microbe
Students construct models of microorganisms recognizing size relationships-comparing the size of viruses with the sizes of bacterial and eukaryotic cells. They put into perspective just how small microbes are by comparing the size of...
Curated OER
Cell Discoveries
Students observe, compare and describe cell organelles in terms of their function, structure and operation. They enter and edit information in a database, build and sort a student-designed database and find records in a database.
Curated OER
Linear Motion 6
In this linear motion learning exercise, students answer 12 questions about acceleration, velocity and distance traveled. They interpret diagrams and indicate the location of an object if it has positive, negative or no acceleration....
Curated OER
Create a microbe
Students explore viruses and bacteria. They construct three dimensional models of microorganisms recognizing size relationships by comparing the size of viruses with the sizes of bacterial cells.
Curated OER
How Small is Small?
Young scholars view the video "The Invisible World" and discuss different types of microscopes and what can be seen with each type. They work in pairs to view several objects with a microscope.
