Bat Detector: Listen to the Secret Sounds of Bats

Science Fair Project Idea

Scientific Method

Do you have bats in your neighborhood? Have you heard them "whoosh" by you, but not been able to see them? In this science fair project, you will be able to detect flying bats by listening in on the ultrasonic signals they produce to locate objects in their environment. The bat detector is a useful and fun tool for studying the biology of this nocturnal flying mammal. Read more

How do plants know which way is up or down? How does this affect which direction their roots will grow? In this lesson plan, your students will investigate how changes in a plant's environment, like the direction of gravity, affect the shape of its growing roots over a period of several days.

NGSS Performance Expectations:

MS-LS1-5. Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.

Bit Depth, Colors and Digital Photos

Science Fair Project Idea

Scientific Method

How many bits of information are in a digital photo? It depends on how many possible colors there are. Learn how to choose the right number of colors and bits to post your photo on the web or send it to your best friend. Read more

How does light interact with matter? In this fun hands-on lesson, your students explore how different materials transmit, absorb and/or reflect light. They create their own experiments to demonstrate these phenomena and use a phones' built-in light sensor and a sensor app to add quantitative data to their arguments. Read more

NGSS Performance Expectations:

MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.

Coming up with new ideas is hard! How do engineers design new things or improve existing ones? Engineers and inventors use different brainstorming techniques to help them think outside the box and come up with new ideas. In this lesson plan, your students will practice brainstorming with a method called SCAMPER. Read more

Bubbling Plants Experiment to Quantify Photosynthesis

Lesson Plan Grade: 6th-8th

Students learn a simple technique for quantifying the amount of photosynthesis that occurs in a given period of time, using a common water plant (Elodea). They use this technique to compare the amounts of photosynthesis that occur under conditions of low and high light levels. Before they begin the experiment, however, students must come up with a well-worded hypothesis to be tested. After running the experiment, students pool their data to get a large sample size,… Read more

NGSS Performance Expectations:

MS-LS1-6. Construct a scientific explanation based on evidence for the role of photosynthesis in the cycling of matter and flow of energy into and out of organisms.
5-LS1-1. Support an argument that plants get the materials they need for growth chiefly from air and water.

Build an Adaptive Game Controller for a Raspberry Pi

Science Fair Project Idea

Engineering Design Process

People with limited mobility, especially in their hands, may not be able to use traditional video game controllers. Adaptive game controllers use a variety of peripherals, like larger buttons, foot pedals, or specialized joysticks, to let people with limited mobility play video games. This video shows how to build a very simple adaptive controller that works with Scratch games on a Raspberry Pi. Can you build an adaptive game controller for a hardware platform and game of your choice? If you… Read more
