Teach the class how to use a microscope to identify bacteria in food. Scholars explore the different parts of the microscope and learn how to determine total magnification. They walk step-by-step through the procedure of preparing slides...

What better way to learn how to use a microscope than building your own? A lab investigation has scholars use lenses from magnifying glasses and sheets of cork to design their own compound microscopes. They calculate focal length...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

No one likes kidney stones, but they are very interesting to learn about. The last installment of a three-part unit has learners experiment with different chemicals to see which one inhibits the growth of calcium oxalate crystals (which...

Scholars explore the procedure for bacteria sampling in a virtual lab by first walking through a detailed step-by-step procedure of preparing the samples of raw milk and pasteurized milk, growing the bacteria, and comparing results....

Scholars use a lab simulation to test contaminated yogurt for bacteria by gram staining. They learn proper lab procedures for handling bacteria and for sterilizing equipment, and then walk through the process on their own to try gram...

In this microscope usage worksheet, 7th graders complete an introduction packet that takes them through several lab activities that helps introduce and familiarize them with using the microscope.

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

Sometimes modeling is the best approach to working with microscopic particles. A lab investigation models a fictional element using pasta. The setup uses three different pasta types to represent three different isotopes. Learners...

In this life cycle workbook, 3rd graders complete several different activities in which they analyze different invertebrates, identify arthropods, examine human biology and plants, and study natural environments. 20 different activities...

Get to know all about sauropods from a paleontologist, Jonah. Following an introductory video, scholars choose from five fossils to learn more about. Each fossil begins with a video, provides information from several different...

In this activity, students use a virtual biology lab to perform investigations and learn lab procedures using compound and dissecting microscopes to look at a variety of animal and plant cells.

Learn how to calculate the total magnification of a microscope on this concise site. Links to making a slide, questions on the use of the microscope, and other related microscope topics are included on this site.

This interactive website about microscopes and microbes provides students with an introduction to cellular biology.

Site is a brief test teachers can use to assess student knowledge of a microscope. No answers are provided.

Extensive site for teachers provides some helpful resources that pertain to plant and animal cells. Includes a microscope diagram as well as plant, animal and pond labs. Also contains links to structures and mechanisms, matter and...

Site is simply a picture of a microscope that has numbers that correspond with each part of it. No answers are provided. A good reproducible if you are looking for a detailed view of the different microscope parts.

In this third unit of a Biology course, students learn about cells and cell structure. They compare prokaryotic and eukaryotic cells and learn about the specialized structures in a cell and what their functions are. They will also learn...
