Sustainable Fishing

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. Read more

Tee Time: How Does Tee Height Affect Driving Distance?

Science Fair Project Idea

Scientific Method

If you're an avid golfer, this might be a fun project for you. When you're setting up to tee off out on the course, how much attention do you pay to putting the tee in the ground? The height of the tee can affect both where in the swing the club makes contact and where on the clubface the ball makes contact. Are you placing your tees at the right height to get the most distance from your swing? Read more

Tee Time: How Fast is Your Golf Swing?

Science Fair Project Idea

Scientific Method

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! Read more

Testing for Bias in a Photo Lineup

Science Fair Project Idea

Scientific Method

You may have read about criminal cases where innocent people have been wrongly convicted of a crime. Sometimes, modern DNA analysis techniques have provided the evidence to exonerate these innocent people. In many cases, mistaken identification by eyewitnesses provided strong evidence for the original conviction. How can prosecutors and defense attorneys make sure that photo lineup procedures used to identify criminal suspects are unbiased? This project shows you how to conduct an objective… Read more

Testing Gait Symmetry with Uneven Loads

Science Fair Project Idea

Scientific Method

The way humans walk—our gait—is usually fairly symmetrical. Each step we take with the left foot is similar in length and timing to the step with the right foot. This symmetry makes walking efficient and reduces stress on the muscles and joints. But what happens when the body is challenged by an uneven load, such as carrying groceries in one hand or holding a backpack on one shoulder? Biomechanics research shows that unequal weight distribution can disrupt gait symmetry, forcing one… Read more

The Case of Mistaken Identity

Science Fair Project Idea

Scientific Method

Mysteries and detective stories have been popular since the time of Sherlock Holmes. The solutions to these fictional cases often involve untangling seemingly contradictory evidence from eyewitnesses. This project studies one procedure used in the real-world process of eyewitness identification of criminal suspects: the lineup. How accurate are eyewitness identifications using various lineup methods? Read more

The Curdling Properties of Different Milks: How to Avoid Little Miss Muffet's Curds

Science Fair Project Idea

Scientific Method

Has a milk-based soup, sauce, or gravy ever curdled on you (formed lumps) as you were preparing it? Curdling is the process of coagulation that occurs where the proteins in the milk clump together. Sometimes curdling is desirable—for example, if you want to make a delicious cheese or yogurt—but if you are trying to make a milk-based soup or gratin, or if you're adding milk to a hot drink, curdling is very unwanted because you lose the smooth, creamy texture. Nobody likes clumps and… Read more

The Effects of a Student-Generated Lesson Summary on Retention

Science Fair Project Idea

Scientific Method

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… Read more

The Eye of the Beholder and the Mind of the Beheld

Science Fair Project Idea

Scientific Method

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… Read more

The Joly Photometer: Measuring Light Intensity Using the Inverse Square Law

Science Fair Project Idea

Scientific Method

You have probably seen light bulbs with different wattages, for example 50 W or 100 W. Higher-wattage lights are brighter but they also consume more electrical power. Are some bulbs more efficient than others, meaning they produce more light per unit of electrical power? You can find out for yourself by making a simple photometer to compare the light output from different bulbs. This project shows you how. Read more
