In this lesson plan, students will take a closer look at the most recent developments in gene editing. Specifically, they will learn about the CRISPR technology using various interactive simulations and other resources. Based on their gained knowledge, students will create a model of the CRISPR-Cas9 components and create a stop-motion animation video of the molecular mechanism of CRISPR-Cas9. Remote learning adaptation: This lesson plan can be conducted remotely. Students can work… Read more

NGSS Performance Expectations:

MS-LS4-5. Gather and synthesize information about technologies that have changed the way humans influence the inheritance of desired traits in organisms.
HS-LS1-1. Construct an explanation, based on evidence, for how the structure of DNA determines the structure of proteins, which carry out the essential functions of life through systems of specialized cells.

Dance Mania: Build Your Own Dance Pad!

Have you ever opened a fresh bottle of carbonated water or soda, poured a glass of it, and just watched as the bubbles fizzed upward in the glass? Have you ever wondered what those bubbles are? They're made of carbon dioxide gas, which was packed tight in the soda before you opened the bottle. Not only can that carbon dioxide gas give you a fizzy drink to enjoy, but it can also give you a show. How? By making candy conversation hearts "dance!" Along the way you will discover some of the fun… Read more

Deep Knee Bends: Measuring Knee Stress with a Mechanical Model

Science Fair Project Idea

Scientific Method

Are you interested in things like prosthetic limbs and artificial joints that can help people with disease or injury to lead a normal life? Or maybe you're interested in sports medicine or physical therapy? Either way, this project could be a good match for you. Find out how the tension on the knee joint changes as a function of angle by building a simple mechanical model. Read more

Deforestation

Science Fair Project Idea

Scientific Method

The conversion of forested to unforested areas has been occurring since humans began to impact and change their environments during the agricultural revolution. Recently deforestation has become a global problem, particularly for developing industrial countries and countries with very large populations. You can use satellite mapping resources to investigate the connection between urbanization, population growth and deforestation. You can also investigate the connection between deforestation… Read more

Design Clothing with Built-In Sensors

Science Fair Project Idea

Engineering Design Process

Have you ever worn a costume that lit up or played sound? Have you ever wished you had a suit of armor with built-in moving parts like a superhero? What if you could make your costume or suit react to your own movements or even other people who bump into you? The Science Buddies activity Weaving a Wearable Touch Sensor shows you how to make a capacitive sensor that responds to touch and can be woven directly into fabric (Figure 1). Can you design a piece of clothing that includes one… Read more

Designing an AI Agent for Expense Tracking

Science Fair Project Idea
