There are many types of construction materials used for wood-frame houses. Compare the different uses for and strengths of different building materials, e.g.: particle board,
plywood, pine, oriented strand board (OSB), and drywall (gypsum board, SheetRock). The Science Buddies Materials Science Resource Stress, Strength and Strain will be helpful for learning about different ways to measure material strength. You should be sure to use the same cross-sectional area of each material in order…

Is an I-beam as strong as a solid beam of the same size? What if you include weight in the comparison: which beam has the greater strength-to-weight ratio? Would an I-beam be stronger than a solid rectangular beam of the same weight? What about other structural shapes (e.g., T-beams, U-beams)? In this project you can find out by setting up a test stand, putting on your safety goggles and measuring how much stress these building components can handle before they snap.

Lesson Plan
Grade: 4th-12th
"Boats" © 2016 Dennis Jarvis
By using a model for how fishing affects marine life populations, students will construct explanations for one of the reasons why fish populations are declining. They will then work to design solutions for ways of making fisheries more sustainable for the animals and the people who depend on them.

NGSS Performance Expectations:
Did you know that you can make a simple hygrometer (a device for measuring the relative humidity of the air) with hair? Search online for instructions to build one. Does the type of hair used in the hygrometer affect the accuracy of the results? Do some types of hair respond faster than others? Do some types of hair give a larger (or smaller) response? You could get hair samples from classmates, or a local beauty shop. Use hair samples of equal length to construct each hygrometer. To force…

When you think of successful inventions from the 1900's that have dramatically changed how people live, what comes to mind? The car? Radio? TV? The computer? What about the microwave oven? You might not remember a time when microwave ovens were not a standard part of most kitchens, but your parents or grandparents probably do. They can remember when heating leftovers took a good 30 minutes in a traditional oven. Or thawing a food from the freezer meant leaving it in the refrigerator overnight.…

The goal of every golfer is to hit the golf ball as far as possible down the fairway. A key factor in determining the distance that the ball will travel is the velocity of the club when it strikes the ball. In this sports science fair project, you will determine exactly how distance is related to club velocity. Time to tee off!

What motivates you to clean your room/mow the lawn/wash the dishes (substitute your own responsibility at home)? What motivates you to do something you really like to do? Or think about this: you'd like to get your younger brother or sister to do you a favor. What strategy works best? Here is a project designed to test which incentive strategy works best for encouraging small children to complete a task.

Peanut butter is a popular ingredient in sandwiches, cookies, and many other common foods. In this cooking and food science fair project, you will roast peanuts in the oven at 350 degrees for 20, 30, and 40 minutes to produce variable levels of color and flavor. Roasting not only adds complex flavors to the peanuts, but it also destroys enzymes that produce off-flavors.
Each lot of roasted peanuts will be used to make a batch of peanut butter. You will evaluate each batch of peanut butter for…

We can't say it any better than he did, so here is Ryan Ponec's capsule description of his excellent project (Ponec, 2002): "At the end of a lesson, a teacher will sometimes have students summarize the information presented by stating, 'Tell me something you learned.' The purpose of this experiment is to determine whether or not this 'lesson summary' significantly enhances the students' ability to later recall the information presented. Students from grade levels fifth through eighth were…

The concept of beauty changes over time and often differs among societal groups. How strongly do societal conceptions of beauty shape an individual's self-image? There are many fascinating questions you could choose to explore with surveys on this subject. For example, how well do girls' ideas of what is attractive in boys agree with boys' expectations about what girls find attractive (or vice versa)? Try your survey with different generations to see how conceptions change over time. If you…
