This discussion of statistical experimental designs is presented in notes with examples added as needed.

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.

Experiment with designs of different hulls for boats to see which hulls are suited for which purpose. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a...

Design different hull designs for boats from milk cartons and experiment with which hull will glide the fastest, be most maneuverable, and which will support the most weight. The Science Buddies project ideas are set up consistently...

A set of exercises where students must analyze statistcal data and methodology and answer questions about distributions, sampling, results, accuracy, frequency, experimental design, and ethical practices.

The goal of this electricity and electronics science fair project is to understand how ions are used to propel spacecraft in space, and to use a NASA online simulator to design your own ion engine. The Science Buddies project ideas are...

There's a lot to understand about the simple propeller to see how it affects lift and thrust in an airplane or helicopter. This Science Buddies project gives you lots of ideas on how to change the design of the propeller to achieve...

In the first part of the activity, each student chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days before weighing it to determine the amount of mass lost. This mass corresponds to the amount...

When doing research, it is important to be aware of one's biases and how to prevent them impacting on the design of an experiment or analysis of a research topic. Learn some techniques used to avoid bias in an experiment.

Students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Each student adds a small amount of baking yeast to a test tube filled with diluted molasses. A second,...

This virtual laboratory demonstrates how an enzyme-linked immunosorbent assay (ELISA) is carried out and some of the key experimental problems that may be encountered. Students will learn about the assay procedure and the equipment and...

Games are designed to help students understand and apply concepts of probability. determine fairness.

Students conduct a simple test to determine how many drops of each of three liquids can be placed on a penny before spilling over. The three liquids are water, rubbing alcohol, and vegetable oil; because of their different surface...
