Bouncing Balls: Collisions, Momentum & Math (for High School)

Lesson Plan Grade: 9th-12th

In this activity, students examine how different balls react when colliding with different surfaces. Also, they will have plenty of opportunity to learn how to calculate momentum and understand the principle of conservation of momentum.Engineering Connection Sports engineering is becoming a popular specialty field of study. While some engineers dedicate their research to understanding collisions between balls and bats, others study the effects of a golf ball colliding with the head of a golf… Read more

NGSS Performance Expectations:

HS-PS2-2. Use mathematical representations to support the claim that the total momentum of a system of objects is conserved when there is no net force on the system.

Calling It Quits: What Is the Most Effective Way to Quit Smoking?

Science Fair Project Idea

Scientific Method

Maybe you know someone who smokes, and you want to help them to quit. They've probably already told you how hard it is to stop once a person has started smoking. This project tries to answer the question: What is the most effective way to stop smoking? Read more

Can Garlic Prevent Crown Gall?

Science Fair Project Idea

Scientific Method

Crown gall is a plant disease caused by the soil bacterium Agrobacterium tumefaciens. This project uses tomato plants to investigate whether garlic extract can prevent crown gall infection. Read more

Candy Confusion: Can Small Children Mistake Medicine for Candy?

Science Fair Project Idea

Scientific Method

Many medicines come in bottles with special child-proof caps so that small children can't accidentally open the bottle and eat the pills. To a small child who can't read the label, the pills might look just like candy. What cues do we use to tell the difference between medicine and candy? At what age can we tell them apart? This project can show you how to find out. Read more

Cha-cha-cha by Latitude

Science Fair Project Idea

Scientific Method

You probably know that where you live on Earth affects your weather. If you live in a far northern or far southern latitude, you experience colder temperatures than people who live near the equator at latitudes close to zero. Your latitude on Earth affects many aspects of your culture, like how you dress, what kind of house you live in, what foods you eat, and even how your day is structured: what time you go to school, to dinner, and to sleep. Some cities at latitudes closer to the equator,… Read more

Coastal and Marine Geology

Science Fair Project Idea

Scientific Method

You can study hazards that affect coastal areas. What geological forces cause a tsunami? A tsunami (Japanese for 'harbor wave') is a wave generated by an undersea earthquake, landslip, or volcanic eruption. You can demonstrate what causes a tsunami by simulating an undersea earthquake with a water table. How does the depth of water effect the height of the wave? Do different slopes of bottom change the speed of the wave? Visit the USGS Coastal and Marine Geology Program to find out about… Read more

Color Mixing with Red, Green, & Blue LEDs

Science Fair Project Idea

Scientific Method

This is a good project for someone who is interested in both electronics and color vision. The equipment needed is on the expensive side, but if you continue studying electronics, you can use it again and again. Read more

Comparing COVID-19 Variants: A Real-World Look at the Effect of Mutations

We hear about COVID-19 variants all the time, but what is a virus variant, how do they come about, and why do they matter? Students will explore these question and more in this lesson plan. They will use SimPandemic, a free online tool, to model what COVID-19 outbreaks look like when communities are exposed to different COVID-19 variants and understand how genetic mutations in a virus can lead to functional changes.

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.
MS-LS3-1. Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.

Compost Creativity: Try Various Methods and Test Soil Fertility

Science Fair Project Idea

Scientific Method

Make your own fertile soil using kitchen scraps, manure, leaves, grass clippings, and other compostable materials. Which materials make the best compost? How does the amount of nitrogen change the rate at which the compost forms? How does a 'hot' compost pile compare to a 'cold' compost pile, or how does traditional composting compare to worm composting, or vermiculture? Figure 1. Different composting methods yield different soils. In this picture, the soil on… Read more

Computer Simulation of an Artificial Neural Network

Lesson Plan Grade: 9th-12th

Using the Netlogo platform to run simulations of a basic neural network called the perceptron, students explore a basic, yet powerful, model of machine learning as they are challenged to understand the logic. Students engage in the perceptron model and discover a weakness of the model. The students then move on to run simulations on Netlogo with the multi-layer perceptron which overcomes the weakness in the original perceptron model. Engineering Connection Machine learning… Read more
