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...

Compare the size and shape of crystals grown in different temperature conditions in this science fair project. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by...

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...

An opportunity for students to experience the nitrogen cycle through observing daily changes in an aquarium. Students test the level of three nitrogen compounds to understand the process of nitrification. Lesson plan gives a lab...

Students will learn how to use appropriate and different procedures, tools, measurements, graphs and mathematical analyses to describe and investigate natural and designed systems in a physical science context.

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.

Presents a procedure for getting a paper clip to float in water. Following the procedure, the site gives a brief explanation and discussion of surface tension.

Contains a procedure for creating slime -- a polymer formed by mixing water, borax, Elmer's glue, and food coloring. Following the procedure, the site contains a brief description of what polymers are.

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.

Contains a procedure for using a plastic straw to create a device capable of producing a duck call when air is passed through. The site introduces the concept of vibration in sound production.

This site presents a procedure for creating your own electromagnet using an iron nail, some wire, and a battery. The site illustrates a connection between electricity and magnetism.

In this lab activity, students are required to write a procedure to be followed in a simple lab process and record the results they get from following that procedure. They then exchange procedures with another lab group, which will have...

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.
