https://www.oercommons.org/courses/science-at-the-waterpark
This activity (on page 2 of the PDF) is a full inquiry investigation into speed and motion and takes place at a water park. Groups of learners will compare two water slides by measuring each rideäóťs length and duration to calculate the speed. They will also attempt to trace a clean line through a maze while riding down the slides to measure which is the wildest.

https://www.oercommons.org/courses/engineering-your-own-spectrograph-2
Students use simple materials to design an open spectrograph so they can calculate the angle light is bent when it passes through a holographic diffraction grating. A holographic diffraction grating acts like a prism, showing the visual components of light. After finding the desired angles, students use what they have learned to design their own spectrograph enclosure.Laboratory for Atmospheric and Space Physics (LASP),Nathanael BoltEducation2015-10-16T16:46:24.324018Course Related MaterialsDon't Confuse Your Qs!

Students investigate the difference between qualitative and quantitative measurements and observations. By describing objects both qualitatively and quantitatively, they learn that both types of information are required for complete descriptions. Students discuss the characteristics of many objects, demonstrating how engineers use both qualitative and quantitative information in product design.Denise W.

https://www.oercommons.org/courses/earthquakes-rock-2
Students learn the two main methods to measure earthquakes, the Richter Scale and the Mercalli Scale. They make a model of a seismographâa measuring device that records an earthquake on a seismogram. Students also investigate which structural designs are most likely to survive an earthquake. And, they illustrate an informational guide to the Mercalli Scale.Integrated Teaching and Learning Program,Janet YowellJessica ToddMalinda Schaefer ZarskeMelissa StratenEducation2015-10-16T16:44:09.693541Course Related MaterialsMeasuring Noise Pollution
https://www.oercommons.org/courses/measuring-noise-pollution-2
Through investigating the nature, sources and level of noise produced in their environment, students are introduced to the concept of noise pollution. They learn about the undesirable and disturbing effects of noise and the resulting consequences on people's health, as well as on the health of the environment. They use a sound level meter that consists of a sound sensor attached to the LEGOÂ® NXT Intelligent Brick to record the noise level emitted by various sources. They are introduced to engineering concepts such as sensors, decibel (dB) measurements, and sound pressure used to measure the noise level. Students are introduced to impairments resulting from noise exposure such as speech interference, hearing loss, sleep disruption and reduced productivity. They identify potential noise pollution sources, and based on recorded data, they classify these sources into levels of annoyance. Students also explore the technologies designed by engineers to protect against the harmful effects of noise pollution.AMPS GK-12 Program,Jerib Carson and Qianqian Lin at the Madiba Prep Middle SchoolViolet MwaffoEducation2015-10-16T16:42:19.537315Course Related MaterialsUltrasound Imaging
https://www.oercommons.org/courses/ultrasound-imaging
Students learn about ultrasound and how it can be used to determine the shapes and contours of unseen objects. Using a one-dimensional ultrasound imaging device (either prepared by the teacher or put together by the students) that incorporates a LEGOÂ® MINDSTORMSÂ® NXT intelligent brick and ultrasonic sensor, they measure and plot the shape of an unknown object covered by a box. Looking at the plotted data, they make inferences about the shape of the object and guess what it is. Students also learn how engineers use high-frequency waves in the design of medical imaging devices, the analysis of materials and oceanographic exploration. Pre/post quizzes, a worksheet and a LEGO rbt program are provided.AMPS GK-12 Program, Polytechnic Institute of New York University,Violet MwaffoEducation2015-10-16T16:41:57.952926Course Related MaterialsTiming a Speedbot!
https://www.oercommons.org/courses/timing-a-speedbot-2
Students strengthen their communicate skills about measurements by learning the meaning of base units and derived units, including speedâone of the most common derived units (distance/time). Working in groups, students measure the time for LEGOÂ® MINDSTORMSÂ® NXT robots to move a certain distance. The robots are started and stopped via touch sensors and programmed to display the distance traveled. Using their collected data, students complete a worksheet to calculate the robots' (mean/average) speeds at given motor powers.AMPS GK-12 Program,Sam Sangankar, James CoxEducation2015-10-16T16:41:56.030619Course Related MaterialsLatex Tubing and Hybrid Vehicles
https://www.oercommons.org/courses/latex-tubing-and-hybrid-vehicles-2
The learning of linear functions is pervasive in most algebra classrooms. Linear functions are vital in laying the foundation for understanding the concept of modeling. This unit gives students the opportunity to make use of linear models in order to make predictions based on real-world data, and see how engineers address incredible and important design challenges through the use of linear modeling. Student groups act as engineering teams by conducting experiments to collect data and model the relationship between the wall thickness of the latex tubes and their corresponding strength under pressure (to the point of explosion). Students learn to graph variables with linear relationships and use collected data from their designed experiment to make important decisions regarding the feasibility of hydraulic systems in hybrid vehicles and the necessary tube size to make it viable.Erik Bowen, Carleigh SamsonVU Bioengineering RET Program,Education2015-10-16T16:40:15.557383Course Related MaterialsBuild an Approximate Scale Model of an Object

https://www.oercommons.org/courses/mega-bounce
In this outdoor activity (on page 2 of the PDF), learners will investigate the transfer of energy using sports equipment. Learners first measure how high different kinds of balls bounce compared to their release point and then repeat the testing but release two balls at once, one atop the other. Learners will observe some very surprising and entertaining results. While one ball will go sky high, there is also a measurable difference in the bounce of the bottom ball.
