Minimizing Bacteria in the Thawing and Cooking of Meat

Science Fair Project Idea

Scientific Method

How does your family thaw and cook meat? Have you ever wondered if it is the safest way? In this practical science project, you can find out and shed light on safe practices in the kitchen by investigating how many viable bacteria are present in samples of meat that have been thawed or cooked using different methods.

Can genetic or environmental factors affect our chances of getting a certain disease? In this activity, your students will model how an existing predisposition can impact the probability of developing an autoimmune disease using dice and M&M's® candy! Read more

NGSS Performance Expectations:

HS-LS3-3. Apply concepts of statistics and probability to explain the variation and distribution of expressed traits in a population.

Students are challenged to use computer-aided design (CAD) software to create "complete" 3D-printed molecule models that take into consideration bond angles and lone-pair positioning. To begin, they explore two interactive digital simulations: "build a molecule" and "molecule shapes." This aids them in comparing and contrasting existing molecular modeling approaches—ball-and-stick, space-filling, and valence shell electron pair repulsion (VSEPR)—so as to… Read more

NGSS Performance Expectations:

HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

Nanotechnology in Action: Organic Electronics

Lesson Plan Grade: 9th-12th

This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an… Read more

Natural Antimicrobial Agents

Science Fair Project Idea

Scientific Method

What do pneumonia, ear infections and strep throat have in common? When they are caused by bacteria (instead of viruses) they are treated by antibiotics. That sounds simple enough, right? You have probably had antibiotics several times in your life. You go to the doctor because you feel lousy, if he or she determines you have a bacterial infection you get a prescription for antibiotics, and within the first day or so you often start feeling much better. Unfortunately, there is a large… Read more

Neanderthals, Orangutans, Lemurs, & You—It's a Primate Family Reunion!

Science Fair Project Idea

Scientific Method

You have probably seen figures showing how human beings are related to chimpanzees, gorillas, and other primates. In this genomics science fair project, you will use bioinformatics tools to generate your own primate family tree. Read more

No Whey! Milk Protein Content Doesn't Change...Or Does It?

Science Fair Project Idea

Scientific Method

Many people you know probably have an opinion about the kind of milk they like to drink—some like it thin and refreshing, others like it thick and rich. Milk can be bought with different fat concentrations, but other than that, it's all the same. Or is it? This science fair project raises a few interesting questions about the other contents in milk. Do all milk products have the same protein concentrations? Do cows produce different types of milk during different stages of lactation?… Read more

Origami

Science Fair Project Idea

Scientific Method

How do you turn a 2-dimensional piece of paper into a 3-dimensional work of art? Origami, the classical art of Japanese paper folding, is loaded with mathematical themes and concepts. What are the common folds in origami, and how do they combine to create 3-dimensional structure? Can you classify different types of origami into classes based upon the types of folds they use? Can you show Kawasaki's Theorem, that if you add up the angle measurements of every other angle around a point, the sum… Read more

Pluck Out & Pick New String Materials for Your Guitar

Science Fair Project Idea

Scientific Method

Walk into any music store and you'll find a dizzying array of string choices for your classical guitar, including rectified nylon, clear nylon, carbon fluoride, bronze wound, phosphor bronze wound, silver-plated copper wire, Polytetra-flouro-ethylene (PTFE), each in a range of tensions from low to high. There is no single best brand or best material. All have their advantages and disadvantages. A set of strings that sounds "sparkling" on one guitar might sound dull on another, primarily because… Read more

Preventing Outbreaks with Herd Immunity

Lesson Plan Grade: 6th-12th

What is herd immunity, how is it achieved, and what impact does it have on outbreaks? Students will explore these questions and more in this lesson plan. They will then use SimPandemic, a free online tool, to model different levels of viral immunity in communities to understand how a population can reach the herd immunity threshold and the impacts that has on individuals and populations during a COVID-19 outbreak. Remote learning adaptation: This lesson plan can be conducted remotely. … Read more

NGSS Performance Expectations:

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.
