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

NGSS Performance Expectations:

5-ESS3-1. Obtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment. http://www.nextgenscience.org/5ess3-earth-human-activity
MS-ESS3-3. Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment. http://www.nextgenscience.org/msess3-earth-human-activity

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 Making of a GMO Crop

Lesson Plan Grade: 9th-12th

Students will compare and contrast methods of selective plant breeding, describe the scientific process of creating a genetically modified plant, compare genetically modified soybean seeds to conventional soybean seeds, describe the impact weeds have on plant growth, and understand how a genetically modified seed can help farmers manage weeds. Read more

NGSS Performance Expectations:

HS-LS1-1. Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins, which carry out the essential functions of life through systems of specialized cells.
HS-LS3-1. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.

The Science of Spin: A Baseball Pendulum

Science Fair Project Idea

Scientific Method

For this project, you'll use a baseball as a pendulum weight, studying the motion of the ball with and without spin. Wrap a rubber band around the ball, and tie a string to the rubber band. Fasten the string so that the ball hangs down and can swing freely. Mark a regular grid on cardboard, and place it directly beneath the ball to measure the motion. You can also time the oscillations with a stopwatch. Lift the ball along one of the grid axes, and let it go. Observe the motion and record… Read more

Trace Your Ancient Ancestry Through DNA

Science Fair Project Idea

Scientific Method

Did you ever wonder about your ancient ancestors? Who they were? Where they came from? In this science project, you will investigate the secrets of your distant past as revealed by your DNA. In order to obtain a sample for DNA analysis, you will scrape a soft swab inside your mouth to collect cheek cells. The cheek cell sample will be sent to a lab for processing, and the results of the analysis will be sent to you. Based on the genetic markers in your DNA, the ancient clan that your… Read more

Tracking Geomagnetic Storms in the Ionosphere

Science Fair Project Idea

Scientific Method

The Sun is the ultimate source of the energy that powers weather systems on Earth. Geomagnetic storms are sun-powered storms in the upper atmosphere, arising from energized particles that are periodically ejected by the Sun. Among other effects, geomagnetic storms can wreak havoc with earth-orbiting satellites, and disrupt satellite communications. The global positioning system (GPS) is a network of 24 earth-orbiting satellites that constantly sends radio signals through the earth's… Read more

Two-Point and Four-Point Methods for Measuring Small Resistances

Science Fair Project Idea

Scientific Method

Measuring the value of a resistor with a multimeter is pretty simple. You set the multimeter to measure resistance, connect the two leads to the resistor (possibly using some handy alligator clips), and read the resistance value. This is called a two-point measurement (one probe on each of the two resistor leads). But what if the resistance you want to measure is very small, in the milli or micro-ohm (mΩ or μΩ) range? This can introduce problems because many low-cost multimeters… Read more

Use Machine Learning to Identify Lyme Disease-Transmitting Ticks

Science Fair Project Idea

Engineering Design Process

Ticks are a growing public health concern in North America, as their populations and the diseases they carry, like Lyme disease, are on the rise. But how can we help people identify the ticks they encounter to reduce their risk of infection? With artificial intelligence! In this project, you will gather image data of three different tick species and use a convolutional neural network (CNN) to classify them. You will also apply image augmentation techniques to expand and enhance the dataset,… Read more

Using Vaccines to Fight Outbreaks

What exactly is a vaccine? Can vaccines prevent outbreaks? How effective does a vaccine need to be to help a population during an outbreak? Students will explore these questions and more in this lesson plan by first learning the biology behind vaccines. They will then use SimPandemic, a free online tool, to model different vaccine parameters to understand how vaccines affect both individuals and populations during a COVID-19 outbreak. Remote learning adaptation: This lesson plan can be… Read more

NGSS Performance Expectations:

MS-LS2-1. Analyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.
MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
HS-LS2-8. Evaluate evidence for the role of group behavior on individual and species' chances to survive and reproduce.
