Science Fair Project Idea

Scientific Method

Want to start a garage band, but Mom or Dad won't let you because it will make too much noise? This is a good project for someone who is interested in acoustics and likes to build things. Who knows, it might help you figure out how to make everyone happy. Read more

From Black to Clear with the Magic of Photochemistry

Science Fair Project Idea

Scientific Method

The rates of some chemical reactions can actually be increased by adding light. Light sometimes interacts with one or more of the chemicals and provides an "energy boost" that dramatically speeds up a normally slow reaction. In this photochemistry science project, you will experiment with the effect of light on a chemical reaction. The reaction converts iodine, which forms a dark-orange solution, to iodide, which is colorless! 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

NGSS Performance Expectations:

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.

This lesson compares and contrasts prokaryotic and eukaryotic cells and examines the form and function of the plasmid found in prokaryotic cells. Students will then use these principles to simulate how a desirable gene can be isolated and inserted into a plasmid as one step in the process of creating a genetically modified organism (GMO).

NGSS Performance Expectations:

HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

Gamers: Myth or Man?

Science Fair Project Idea

Scientific Method

Male or female? Fat or skinny? Outgoing or quiet? What is your stereotype of a "gamer"? Do your friends have the same mental picture of gamers? How about your parents? This science fair project will help you examine whether the stereotypes of "gamers" actually matches the reality of who plays video games. Read more

Genetically Engineer Yeast to be Fluorescent

Science Fair Project Idea

Scientific Method

Can you imagine a glowing loaf of bread? You might not be able to make the whole loaf glow, but you can get baker's yeast to fluoresce! The way to do this is to modify the genetic information of the yeast organism. The technology that is used to do this is called genetic engineering. With genetic engineering, you can insert a fluorescent protein gene from a jellyfish into yeast cells, so they start glowing under blue light! Do this project to see for yourself! Read more

Genetically Modified Foods

Science Fair Project Idea

Scientific Method

Genetically modified organisms (GMOs) are organisms whose DNA have been manipulated to give them new traits. In genetically modified (GM) food crops traits like resistance to drought or pesticide might be added, or the crop may have been made more nutritious, or the taste may be altered to give you something like the impossible burger. Are there GMOs in your favorite foods? Many countries have implemented or are in the process of implementing GMO labeling on foods, but with a little bit of… Read more

Germination

Science Fair Project Idea

Scientific Method

Germination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental… Read more

Getting a Bang Out of Breath Spray: Studying the Chemistry and Physics of a Small Explosion

Science Fair Project Idea

Scientific Method

Hold onto your hats! In this science fair project, you will make a device that sends a film canister across the room with a small chemical explosion. The energy for the explosion is derived from the combustion of ethanol. You will determine the launch velocity of the canister, as well as devise ways to study changes in gas pressure and volume due to the explosion. This science fair project is sure to take your breath away! Read more

How easy or difficult is it to build a gingerbread house? It depends on what you want your house to look like. Design possibilities are almost endless! You could make a multi-story building, try different shapes and sizes, or add extra features such as a balcony or chimney. The more complex your design gets, the more difficult it is to make sure that your house stays upright and keeps its shape. In this activity, you will become an engineer and design and build a gingerbread house that must… Read more
