Tracking SARS-CoV-2 Spread from Wastewater

Science Fair Project Idea

Scientific Method

Have you ever wanted to know where hot spots of infection are or see how viruses spread? Are you interested in seeing how this changes over time? Check out our new science project that uses data visualization tools and tested wastewater data to track the virus that causes COVID-19 over time. Read more

NGSS Performance Expectations:

4-LS1-1. Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior, and reproduction. [Clarification Statement: Examples of structures could include thorns, stems, roots, colored petals, heart, stomach, lung, brain, and skin.] [Assessment Boundary: Assessment is limited to macroscopic structures within plant and animal systems.]
4-LS1-2. Use a model to describe that animals receive different types of information through their senses, process the information in their brain, and respond to the information in different ways. [Clarification Statement: Emphasis is on systems of information transfer.] [Assessment Boundary: Assessment does not include the mechanisms by which the brain stores and recalls information or the mechanisms of how sensory receptors function.]

Understand Shock Levels and Packaging Principles

Science Fair Project Idea

Scientific Method

When you open up your presents on your birthday, you probably don't spend a lot of time admiring the wrapping—you'd much rather see what's inside. It can be the same way with the packaging that products come in, but packaging is important for protecting the things we buy as they make their way from the factory to our homes. How much shock force is produced when a box gets dropped accidentally? What kinds of materials work best to protect products from damage? This project can show you… Read more

Understanding the Emotions Hidden in Words with Sentiment Analysis

Science Fair Project Idea

Scientific Method

Sentiment analysis helps us understand the emotions behind text, such as whether people feel positive, negative, or neutral about a topic. It is useful for analyzing opinions on social media, reviews, or other text data. In this project, you will gather text data on a topic of your choice and use a sentiment analysis tool called VADER (Valence Aware Dictionary and sEntiment Reasoner). Read more

Upstairs, Downstairs: Turning on a Light from Two Places

Science Fair Project Idea

Scientific Method

Maybe somewhere in your home there's a long hallway or a stairway with a light that you can turn on from either end. It's a nice convenience, but did you ever wonder how it's wired up to work that way? The goal of this project is to build a similar circuit with switches, flashlight batteries and a flashlight bulb (obviously, household circuits are not safe to experiment with). You'll need to understand the difference between connections made in series and connections made in parallel in an… Read more

Use Sewable Circuits to Make Cool Costumes and Accessories

Science Fair Project Idea

Engineering Design Process

Do you want to add color-changing lights to your own clothing, costume, or fashion accessory? What about making the lights flash, or adding sensors to make them automatically react to things like temperature or motion? You can do it all with sewable circuits, also called wearable electronics, that let you sew circuit parts directly into fabric. You can make anything from a basic circuit with a few LEDs up to a programmable, Arduino-compatible circuit with multiple sensor inputs and multiple… Read more

Use the Force! Push & Pull Robots With an Invisible Force

Science Fair Project Idea

Scientific Method

If you have seen any of the "Star Wars" movies, then you probably remember when Jedi knights like Luke Skywalker and Obi-Wan Kenobi used "The Force" to push, pull, and even throw objects — including some helpless battle droids. Have you ever wished you could do that in real life? In this robotics project, you will build and program a LEGO® robot that you can push and pull using an "invisible force" — almost like a real Jedi! We make no promise that you will be taking down the… Read more

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 Urine in a Microbial Fuel Cell

Science Fair Project Idea

Scientific Method

Every day, we produce a lot of sewage (wastewater full of feces and urine). In fact, it adds up to 6.4 trillion liters of urine alone produced worldwide each year! The sewage is collected and then treated or disposed of. But what if, along the way, there were a way to make that sewage do something useful? Human urine is rich in nutrients, and some bacteria actually thrive on eating those nutrients. There are also devices called microbial fuel cells that can generate electrical power by using… Read more
