This inquiry lab activity involves students working to understand that sound is made from vibrations.

How to solve for the horizontal displacement when the projectile starts with a horizontal initial velocity. We also explain common mistakes people make when doing horizontally launched projectile problems. Created by David SantoPietro.

Amplitude, period, frequency and wavelength of periodic waves. How to calculate wave velocity. Created by Sal Khan.

This activity is an extension of the FOSS Variables Lifeboat investigation. Students choose a lifeboats variable to investigate, write up an experiment based on the variable to be tested, test the variable, and create a lifeboats investigation poster to share their results.

These flow charts show carbon dioxide emissions for each state, the District of Columbia and the entire United States. Emissions are distinguished by energy source and end use.

This video segment adapted from Shedding Light on Science describes how astronomical distances can be measured in units of light-years, and how the finite speed of light allows astronomers to study how the universe looked long ago.

In this decision-making exercise, students investigate what would occur if a dam were built along Nanticoke Creek, a real stream just north of West Corners near the Village of Endicott, New York. They will use topographic maps to determine how much area would be flooded by the new reservoir, to study river drainages, and to consider the impacts of dams on a region. They must also consider rivers in the context of their relation to humankind. The exercise can be extended to other, more local locations having similar topography.

Many people consider analog electronic circuit design complex. This is because designers can achieve the desired performance of a circuit in many ways. Together, theoretical concepts, circuit topologies, electronic devices, their operating conditions, and the system's physical construction constitute an enormous design space in which it is easy to get lost. For this reason, analog electronics often is regarded as an art rather than a solid discipline.

Structured Electronics Design:

Defines a step-by-step hierarchically organized design process.
Is based on solid principles from systems engineering, physics, signal processing, control theory, and network theory.
Provides a solid foundation for circuit design education and automation.
Has been developed at the TU Delft since the 1980s.

Data set and map pertaining to energy production for all countries. The World Bank specifies energy production as a World Development Indicator (WDI) -- the statistical benchmark that helps measure the progress of development.

This blog post by the Fast Plants Team provides a materials list and instructions for a Do-It-Yourself, LED Grow Light that is ideal for Fast Plants growth. This grow light uses cost-effective materials that can be obtained online and from a local hardware store. The light is easy to construct, powerful, and height adjustable, which helps simplify the goal of keeping your grow light close to your developing Fast Plants. This post also explains what it means to provide optimal lighting for seedlings and describes why it is important to understand light intensity and its effect on growing plants.

This is a lab activity that allows students to collect data to practice using effective measurement. While other authors have produced similar labs, this version includes uncertainty analysis consistent with effective measurement technique as presented in the module Measurement and Uncertainty.

Effective measurement techniques include the concept of measurement uncertainty. Students may make erroneous conclusions analyzing data using measurements that do not include the uncertainty of the measurement. In this lab, students determine a density range for a metal and identify the material based on this range.

Welcome! In light of the COVID 19 pandemic and school closures, Portland Metro STEM Partnership has worked with thier partnering districts to create and curate distance learning resources for students.The following resources were developed by district science TOSA teams and the Portland Metro STEM Partnership (PMSP) Physics, Chemistry, and Biology Councils. These Councils represent curriculum development leads and master HS teachers from Beaverton, Hillsboro, and Portland Public. Thank you, district science leaders and PMSP Content Council leaders, for developing this set of distance learning resources for high school students!

Let’s make Cheetos!  In this food science unit, students walk through careers in the food industry, sensory analysis of food, the formulation of a product, branding and marketing of a food product, and finally making physical product of fried cheese puffs. Written by Tyler Schindler

This U.S. Geological Survey clearinghouse provides a diverse array of over 40 links to information on the Yellowstone volcanic system. The links are organized by category, including background and information; special items of interest; maps, graphics, and images; items of interest; useful links; educational outreach; and other menus of interest.

Modeling Our World with Mathematics Unit 2: Environmental Science Topic 2 - Sustainable Forestry

In this lesson, students learn about sound. Girls and boys are introduced to the concept of frequency and how it applies to musical sounds.

Direct Energy Conversion discusses both the physics behind energy conversion processes and a wide variety of energy conversion devices. A direct energy conversion process converts one form of energy to another through a single process. The first half of this book surveys multiple devices that convert to or from electricity including piezoelectric devices, antennas, solar cells, light emitting diodes, lasers, thermoelectric devices, and batteries. In these chapters, physical effects are discussed, terminology used by engineers in the discipline is introduced, and insights into material selection is studied. The second part of this book puts concepts of energy conversion in a more abstract framework. These chapters introduce the idea of calculus of variations and illuminate relationships between energy conversion processes.

EME 812 explores the main physical principles of core solar energy conversion systems, including direct power conversion photovoltaics, concentrating photovoltaics (CPV), and thermal conversion to electricity via concentrating solar power strategies (CSP). It also covers the fundamentals of enabling technologies such as light concentration, solar tracking, power conversion cycles, power conditioning and distribution. Learning in EME 812 relies on analysis of design and performance of existing solar plants that have been deployed in areas such as the southwestern USA, Spain, and North Africa.

This activity involves students in recording their energy usage of particular appliances and devices over a certain period of time. They then take the time and device and determine the kilowatts of electricity used via an internet website. They then can take this value and calculate the amount of fuel that would have to be burned to generate this same amount of electricity. This activity is done for multiple appliances and situations and it is investigated how much fuel/coal is needed to kepp the light on all day every day, or the computer that is never in sleep mode.
