This two-day experiment uses different concentrations of sugar to study the rate of fermentation. Students observe the rate of carbon dioxide gas produced by yeast to infer the rate of fermentation. Lesson plan gives a lab procedure,...

[Free Registration/Login may be required to access all resource tools.] An overview of science laboratory procedures including information about lab equipment, lab safety, and general techniques. After the reading, watch a short video...

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.

Using microbiology techniques, students will explore the effect of iron on the fluorescence of several species of bacteria. Studying bacteria in an iron scarce environment allows students to see the fluorescence released. Lesson plan...

With this simple stain, students can observe the shape of yeast and bacteria under the microscope. Lesson plan gives a lab procedure, teacher instructions, points for discussion, and additional activities. Lab does require the purchase...

In this experiment, students will test the quality of a water sample by observing the number of coliform bacteria. Coliform bacteria are found in human intestines and a large amount can indicate water contamination. Lesson plan gives a...

Tons of science safety rules and information are available here, arranged by category. Resources are available for students and teachers on maintaining safety during labs and other activities.

This site contains a brief procedure for building (and launching) a balloon powered rocket. Introduces concepts of air pressure and propulsion.

An idea developed by a physical science teacher who applied Newton's Laws of Motion in creating a balloon powered race car. Find simple objective, materials, rules, and procedures.

A lab where students can investigate eggs and what happens to egg whites after they are beaten. Lesson plan includes teacher background, standards, and a procedure for students to develop their own experiment.

Using a voltage sensor, students will measure how much "electricity" is produced by the wind turbine that they design and build. Students will experiment with blade designs to see which one collects energy from the wind the most...

[Free Registration/Login may be required to access all resource tools.] The standard safety symbols and practices used in a biology laboratory are covered in this lesson.

A science experiment to observe the growth of a colony of yeast cells. Students should also be able to observe the hyphae and mycelia structures. Lesson plan gives a background, lab procedure, teacher instructions, points for discussion,...

Observe the two species of bacteria that are found in yogurt by cultivating them on agar plates. In this lab, students will use microbiology techniques to explore these anaerobes. Lesson plan gives a lab procedure, teacher instructions,...

A science experiment to observe the rate of carbon dioxide gas produced by yeast. Students will get a visual of the process of fermentation. Lesson plan gives a lab procedure, teacher instructions, points for discussion, and additional...

This resource presents a collection of simple science experiments kids can do using household materials. The procedures include diagrams and are simple to follow.

Using the wet bulb-dry bulb method, students will compare the temperature of a dry temperature sensor and a wet temperature sensor. By comparing the temperatures, students will be able to find the relative humidity. After completing the...

A science experiment to observe how microbes are transferred by hand contact. This lab creates a model to show students how microbes transfer disease. One student will rub their hand with candy soaked in a yeast solution, then students...

A lab activity where pond water samples are collected to observe the requirements for the growth of phototrophic organisms. To observe these requirements samples are separated into different variable groups. One group is incubated in the...

Use the sun's energy to cook an egg? Design, build and test a solar oven. Activity gives a procedure to build oven as well as questions to answer. Questions can be saved and graded by instructor.

[Free Registration/Login may be required to access all resource tools.] Students learn about science laboratories, the types of equipment that are used in them, and about safety guidelines in a laboratory.

Simple experiment to demonstrate the effect of temperature on solid solubility. Includes procedure, questions, data sheet, and answers to the experiment.
