Using a Magnet as an Electrical Current Detector

Science Fair Project Idea

Scientific Method

An electric current produces a magnetic field. You can take advantage of this fact to make a simple apparatus to test the electrical conductivity of various materials, including both solids and liquids. The detector consists of a coil of wire, with a magnetic compass inside it. You connect one end of the coil to a D-cell battery. The other end of the coil is connected to whatever material you are testing, and the material, in turn, is connected to the other end of the D-cell. In other… Read more

Using Empirical Data in the Classroom: Raptor Migrations!

Lesson Plan Grade: 5th-10th

"Osprey with Gulls" © 2014 Lee Jaffe Why do birds migrate? How do seasonal changes in primary productivity influence the behaviors of higher order consumers like raptors? Visualize and explore the connectedness of organisms within and across ecosystems in this teacher-guided activity. Read more

NGSS Performance Expectations:

MS-LS2-2. Construct an explanation that predicts patterns of interactions among organisms across multiple ecosystems.
MS-LS2-3. Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.
MS-LS2-4. Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.

Using the Solar & Heliospheric Observatory Satellite (SOHO) to Determine the Rotation of the Sun

Science Fair Project Idea

Scientific Method

Here's a cool project that shows you how to use images from an orbiting observatory to measure how fast the Sun rotates. Read more

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.

Volleyball Machine Challenge for Middle School

Lesson Plan Grade: 6th-8th

Teach your students about the engineering design process with this fun lesson plan. They will design and build two "volleyball machines" that launch a ping pong ball back and forth over a net. While the 2019 Engineering Challenge is over, your students can still try this project and compare their scores to top scores from around the world! Teachers, note that elementary school and high school versions of this lesson plan are also available. Looking for this year's challenge? Check out our… Read more

NGSS Performance Expectations:

MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
MS-ETS1-4. Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Water-Wise: Building a Rainwater Collection System

Science Fair Project Idea

Scientific Method

We are all familiar with the nursery rhyme, "Rain, rain, go away, come again some other day...", or the song "Singin' in the Rain." Numerous songs and stories describe our feelings about rain. Why so many? Because we humans understand how important rain is to our well-being. Rainfall, as part of the water cycle, brings water back to Earth that had previously evaporated or transpired from the surface. When water vapor in the atmosphere condenses into clouds and falls back to Earth as rain,… Read more

What is a normal body temperature for humans? Have you heard people say it is 98.6°F or 37°C? You will find out for yourself if that is fact or fiction in this simple activity. Read more

What is the Maximum Intermediate Height for a Siphon?

Science Fair Project Idea

Scientific Method

A siphon is a handy device for emptying out a liquid reservoir that has no drain. For example, they're great for cleaning fish tanks. An interesting aspect of a siphon in action is that the liquid flows "uphill" for a portion of its journey through the tube. This project asks the question, is there a maximum height for that uphill part of the siphon? Read more

What is the Most Effective Treatment for Whitefly Infestations on Plants?

Science Fair Project Idea

Scientific Method

Whiteflies are a group of closely related insect species whose larvae live on plants. Like aphids, they suck nutrients from the plant's circulatory system. What is the most effective method for fighting a whitefly infestation in your garden? This project has some ideas for you to try. Read more

What is the Rate of Leaf Growth Along the Stem?

Science Fair Project Idea

Scientific Method

Leaves grow in a different pattern than stems and shoots. They do not elongate along one axis, but instead spread out over time. Do all regions of the leaf grow equally? You can use markings on different regions of a growing leaf to see if the whole surface grows, or if growth is focused in a particular region, like the veins or edges of the leaf. If you look along a leafy stem, you may notice that leaves at different positions along the stem are different sizes. You can do an experiment to… Read more
