Which modification is the best? Using the scientific method, pairs determine the effects of each control surface on the distance of a glider's flight. The activity, section 16 in a 22-part unit on aviation, allows pupils to gain a better...

A neatly formatted outline of the steps of the scientific method can be used as a reference sheet for your future science fair participants. For each step, you will find a few guiding questions or points to remember when working on...

If I change the length, will they work better? After brainstorming the variables of wind turbine blade design, groups choose one variable to isolate and test. The groups then present their data to the class in order for all to have the...

Students are introduced to the principles involved with technological design. In groups, they use the Internet to research an important historical innovation and how it changed the world. They discover the barriers that were involved in...

Build problem-solving skills with science! Step-by-step videos walk investigators through each stage of completing a science fair project. Scientists learn to formulate a testable question, design an experiment, collect data, draw...

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

How does the dirt get out of your drinking water? A hands-on activity introduces the use of flocculants to help clear solid particles out of water. The plan walks learners through the process of setting up an experiment that...

A terrific lesson focused on the design process. It begins with a presentation, "Design: Solve a Problem," which lists the steps of the process and then introduces the specific challenge: to build a device that measures wind speed....

Seventh graders identify and create questions and hypotheses, dependent and independent variables and form a conclusion that can be answered and tested through scientific experimental investigation. In this relationship lesson, 7th...

How diverse are the benthic organisms found in local streams? Using the information learned in previous lessons on identification of macroinvertebrates and on calculating stream index values, groups determine the health of local...

Students explore, experience and experiment identifying the human impact on the environment of vegetative differences within the same biome. They assess what causes deserts, rain forests, savannahs, tundras and saguaros and how these...

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...

This curricular unit contains two lessons that let students actually do the work of scientists as they design their own experiments to answer questions they generate. In the first lesson and its associated activity, students conduct a...
