"Nuclear Power Plant Cattenom" © 2005 Stefan Kühn In these two activities, students will explore two consequences of burning fossil fuels: air pollution and the greenhouse effect. For a comprehensive unit on fossil fuels, this lesson works especially well as an extension to Fossil Fuels: Chocolate Chip Mining. Read more

NGSS Performance Expectations:

4-ESS3-1. Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment
MS-ESS3-4. Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.

Frequency Histograms

Science Fair Project Idea

Scientific Method

Can you remember what the weather was like last week? Last year? Here's a project that looks at what the weather was like for over a hundred years. You'll use historical climate data to look at moisture conditions in regions across the continental U.S. You'll use a spreadsheet program to calculate the frequency of different moisture conditions for each region and make graphs for comparison. Which part of the country has the most frequent droughts? The most frequent periods of prolonged… Read more

From Farms to Phytoplankton

Lesson Plan Grade: 6th-11th

"Morganza Spillway" © 2011 NASA Earth Observatory Can we use a model to predict the impacts of nutrient pollutants on an aquatic ecosystem? In this activity, students participate in a kinesthetic simulation to illustrate how nutrient pollution from agricultural runoff can lead to a dead zone at the mouth of a drainage basin. Read more

From Your John to the School Lawn: Is Recycled Water Really Safe?

Science Fair Project Idea

Scientific Method

Reclaimed (treated) wastewater can be used for many purposes, including landscape watering and freeing up valuable fresh water for other purposes (like drinking water). It's a great way to conserve water, but is it really safe? This science fair project is designed to find out. Read more

Geomagnetism

Science Fair Project Idea

Scientific Method

What is geomagnetism, and how does it affect the earth? Visit the USGS Geomagnetism program for more information about this invisible force (USGS, 2006). How is the earth's magnetic field patterned? Are the magnetic poles located at the exact North and South Pole? How can the fields be mapped on the Earth's surface? What is declination? Use the mapping tools to study changes in declination patterns over time. (USGS, 2006) Read more

Do you ever wonder why we perform tasks in a particular way? Very often, we learn by copying someone and never stop to question if there is a more efficient or easier way to do something. This activity is about the tricky task of pouring from a full container. Could there be an easier way to do it? Read more

Golf Clubs, Loft Angle, and Distance: The Science of Hitting

Science Fair Project Idea

Scientific Method

Use a video camera to analyze the angle of lift with different clubs. Measure the distance the ball travels. Be sure to conduct a sufficient number of trials with each club so that your results are consistent. This can also be a great way to work on your swing! (Idea from Goodstein, 1999, 83-85.) Read more

Classifying happy and sad faces is an easy task for most humans, but can we teach a machine to do it? In this fun lesson, students will use machine learning to try this out and see how easy it is for bias to creep in. This experiment requires no computer programming skills! In an optional extension, students will also use their imaginations to explore the potential benefits and dangers of artificial intelligence solutions. This lesson will give students an awareness of how prevalent artificial… Read more

NGSS Performance Expectations:

MS-ETS1-1. Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.
MS-ETS1-2. Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

He Huffed, and He Puffed, But Didn't Blow the House Down! How Can Straw Make a Sturdy Building?

Science Fair Project Idea

Scientific Method

In the fairy tale of the three little pigs, the wolf huffed and puffed and blew down the first pig's straw house. But in reality, straw, tied into bales, is a viable building material that, when used properly, makes sturdy and energy-efficient buildings. Straw is a renewable resource that is available all over the world since it is the byproduct of growing grain. In this science fair project, you will test a straw bale covered with stucco to see if it's water resistant, and evaluate if it's… Read more

Hey Gear Heads! The Physics of Bicycle Gear Ratios

Science Fair Project Idea

Scientific Method

If you have a multi-speed bike, you know that you can make it easier or harder to pedal just by shifting gears. Ever wonder how that works? You can investigate this a number of ways. A basic approach is to use a selection of spools of thread (with different diameters), a board with two nails, and a rubber band. Place a spool over each nail, and put the rubber band over them. Mark the 12:00 position on each spool so that you can count revolutions. Turn one spool through a full circle and… Read more
