I bet I can cross the room without having the lights come on. Class members set up an experiment in which they try to determine what materials will mask motion detected by a sensor. Groups predict how materials will interact with...

Students experience a guided inquiry into the workings of an ultrasonic motion detector. They are led to study something they cannot see, hear, feel or taste. Students design strategies to avoid becoming prey of the predatory "Batzilla."

Groups rotate through a series of stations and work with a partner to observe sound waves. Children describe sound in terms of pitch, volume, and frequency. To apply their new knowledge, the class considers how these observations can...

Is it possible to change the color of clouds? A three-part activity explores the scattering of light by the water droplets that make up clouds. After observing a demonstration, curious scholars conduct their own investigations of the...

In this biology worksheet, students take part in an examination of the graphic organizer to determine the different types of environments and how they effect the survival of microbes.

Using a karaoke machine, a guitar, and other devices, learners explore the way sound waves travel. Using this hands on approach, learners can get a better understanding of wavelength, frequency, and more.

Young scholars participate in an experiment to understand how robotic systems can estimate distances.  In this robotic ranger lesson, students measure the the time it takes for and object to move back and forth.  Young scholars...

Students calculate the distance they will travel. In this geometry lesson, students use the TI and CBL system to make calculation of a certain path. They explore geography by calculating distances between different areas as it relates to...

Students investigate wind speed. In this wind instrument lesson, students build an anemometer to measure wind speed and discuss the importance of wind speed knowledge in various professions. 

In this reading comprehension worksheet, students read a passage titled, "CW The Robot," then complete 12 short answer comprehension questions. 

Eleventh graders work in groups and investigate how force determines the speed and distance then they view the video, "Math Vantage #7: What's Your Angle?." They are given a real life problem to solve using speed, ramps, angle, incline...

In this science worksheet, students locate 28 words in a word search. The focus of the word search is vocabulary connected to the study of sound waves.

Students investigate ways to protect themselves against AIDS while learning compassion for the those with the disease. In this HIV/AIDs instructional activity, students discuss ways to protect themselves against contacting the disease....

Students examine the components of a sonar system. In this physical science instructional activity students explain how multibeam and sidescan sonar systems are useful to ocean explorers.  Students simulate sonar operations in an...

Young scholars learn how ultrasonic sensors work, reinforcing the connection between this sensor and how humans, bats, and dolphins estimate distance.

A brief explanation of what ultrasonic sound is and the devices that produce ultrasonic sound can be found here at the Georgia State University. Scroll down the page to read how ultrasonic sound is important to bats and towards the...

Students' understanding of how robotic ultrasonic sensors work is reinforced in a design challenge involving LEGO MINDSTORMS NXT robots and ultrasonic sensors.

Sometimes bats can "whoosh" right by you, and not be seen. 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...

Students use ultrasonic sensors and LEGO MINDSTORMS NXT robots to emulate how bats use echolocation to detect obstacles. They measure the robot's reaction times as it senses objects at two distances and with different sensor threshold...

Students identify different bridge designs and construction materials used in modern day engineering. They work in construction teams to create paper bridges and spaghetti bridges based on existing bridge designs. Students progressively...

The concept of pitch and frequency is covered in this tutorial. Learn what frequency and pitch are, the difference between infra sound and ultrasonic frequencies, and how pitch is related to the frequency of a sound.

Students experience data collection, analysis and inquiry in this LEGO MINDSTORMS NXT -based activity. They measure the position of an oscillating platform using a ultrasonic sensor and perform statistical analysis to determine the mean,...

Students learn about sound waves and use them to measure distances between objects. They explore how engineers incorporate ultrasound waves into medical sonogram devices and ocean sonar equipment. Students learn about properties, sources...

Student teams design their own booms (bridges) and engage in a friendly competition with other teams to test their designs. Each team strives to design a boom that is light, can hold a certain amount of weight, and is affordable to...
