A good first step to read. This set of recommendations or advice comes from the California State Science Fair Committee. Read carefully the first three paragraphs and the "Students are advised" paragraph.

[Free Registration/Login may be required to access all resource tools.] Explores the criteria of a scientific hypothesis and why a hypothesis cannot be proven true.

Find out what variables are in a scientific investigation and what the difference is between an independent, dependent, and controlled variable. Look at samples of different types of variables and find out what makes a good variable.

This lesson engages students in learning about plant growth. Students will observe changes in a growing plant and then will write in their discovery journals to write observations and hypotheses about the plant growth. Students will also...

Use "Dinosaur Train" to illustrate and excite your students about creating a hypothesis. Website includes a video of "Dinosaur Train", a lesson plan, and student's handout. Lesson plan includes a lab where students can practice making...

The conclusion of a science experiment summarizes how your results supported or contradicted your hypothesis. See a sample of a conclusion and find out what makes a good conclusion.

A video and a short multiple-choice quiz on identifying possible outcomes and making predictions.

Learn what a prediction and a hypothesis are in statistics and how they differ. Includes examples demonstrating the differences.

This course enhances science literacy by emphasizing the repeated practice of making observations, posing questions & developing hypotheses around a narrowly focused aspect of Minnesota Geology. Students construct new knowledge using...

How do you know when your hand touches something? How do you know if something brushes against your shoulder? Think about your fingertip, arm, and back. In which of these places might your nerves be closer together? Review the concept of...

This lesson plan requires students to make an inference (hypothesis) about two animals based on the tracks they leave behind. Students are asked to write a story explaining their inference.

Learn about conducting your own investigation with these tips on following the scientific method. Find out how to state hypothesis, make observations, collect and analyze data, and display data to share results and conclusions of your...

This mini-lesson at the Evolution and Nature of Science Institute site from Indiana University provides a criteria by which students can evaluate an idea or explanation for scientific credibility.

This site from Glencoe Publishing not only explains hypothesis but also tells how to design an experiment to test your hypothesis. Includes the difficult task of "Separating and controlling variables."

Students will formulate a hypothesis about the relationship (linear, direct, indirect, etc.) between the distance a drop of blood falls and the diameter of the splatter it makes. To test their hypothesis, the students will work...

Play a game of concentration by matching terms used in the scientific method to their proper description.

In this earth science lab, students will find, identify, and create a visual presentation of the rocks that are found around their school. They will determine the mass, volume, density, color, texture, and hypothesize what each rock is....

Designed by the Open University and the BBC, this website from Open2.net explores ecosystems. Included is a lengthy discussion on closed ecosystems and their importance to research, as well as a virtual ecosystem, an interactive showcase...

By the end of this section, you will be able to explain how the methods of science are used to make scientific discoveries; define a scientific model and describe examples of physical and mathematical models used in physics; and compare...

Through this series of three lessons, students will gain an understanding of the basics of mineral science. In their investigation they will also work through the scientific process as they practice their observation skills, form...

Identify simple principles of physical science and engineering by exploring ramps and things that roll. Predict which items will slide or roll down a ramp and test your predictions.
