The purpose of this task is for students to compare two fractions that arise in a context. Because the fractions are equal, students need to be able to explain how they know that.

Looking for a fun and engaging way for your students to work on collaboration and using the engineering design process? STEM Challenge: Marshmallow Tower is for you! Simple and cheap materials and little prep required.

In this activity, students will use their knowledge of area and perimeter to create a racetrack. Once they have the correct specifications they will guide their car through the track using the properties of magnets.

This guidebook was created by ISKME, in partnership with the Science Education Resource Center (SERC) at Carleton College. The document provides a practical reference for curators and authors of STEM OER, and contains 23 accessibility criteria, or elements, to reference as they curate, design and adapt materials to be accessible for STEM learners.

The primary audience of this resource is STEM postsecondary faculty, instructional designers, and others responsible for course design and pedagogy who seek to:

- Expand their knowledge about accessibility and ways to integrate it into their STEM curriculum and instruction
- Design openly licensed STEM courses and course materials that support both access and use by learners
- Curate existing STEM content that expands upon traditional textbooks and courseware to address variability in learning
- Identify and add meaningful keywords, or tags, to the STEM OER they create, so that their OER can be more easily discovered across platforms

Professional learning teams on campus are also encouraged to use this framework as part of training to facilitate integration of accessibility concepts into STEM course design and pedagogy.

The framework and guide development was supported by a mini-grant program facilitated by Bates College and the SCORE-UBE Network (Sustainability Challenges for Open Resources to promote an Equitable Undergraduate Biology Education), with funding from The William and Flora Hewlett Foundation. The framework and guide were developed by ISKME and SERC with input from 21 STEM faculty members from across the United States, and in collaboration with the project’s Working Group of accessibility experts: Andrew Hasley and Hayley Orndorf, both with BioQUEST’s UDL Initiative and the Quantitative Undergraduate Biology Education and Synthesis (QUBES) Project; Hannah Davidson, Plymouth State University; and Cynthia Curry, National Center on Accessible Educational Materials (AEM)/CAST.

In Save the Penguins, the broad context is global climate change. Students learn that the energy we use to heat and cool our houses comes from power plants, most of which use fossil fuels to convert chemical energy to electrical energy. The burning of fossil fuels has been linked to increased levels of carbon dioxide in the atmosphere, which in turn has been linked to increases in global temperature. This change in temperature has widespread effects upon life on Earth. Penguins live in the southern hemisphere, primarily on the icy continent of Antarctica. As the Earth warms and ice melts, penguins lose habitat. Therefore, students see that better-designed houses that use less energy for heating and cooling can have an effect on penguins. Energy efficient houses that
minimize unnecessary heat transfer will draw less electricity from the fossil fuel burning power plants and not contribute as much to global climate change.

Students will analyze ratios and use proportions to solve problems using a cooperative, kinesthetic activity in which they will create “human ratios.” Students will use ratios to compare two quantities, then solve problems cooperatively by demonstrating how proportions are written to show equivalent ratios.

Description:

Build a model of the Earth, with its spin-axis, and a lamp as the Sun to demonstrate the concept of seasons.

Goals

--Understanding why we have seasons and the cause of seasonal variation in temperature.
--Learning about how the Earth rotates on a tilted axis compared to its orbit around the Sun.

Learning Objectives

--Students learn about seasons by building a model of the Earth and the Sun, and investigating how sunlight hits the Northern and Southern Hemispheres during different seasons.
--Students explain that the same amount of light hitting the ground heats up a small area more than a large area
--Students show that the angle at which the sunlight hits the Earth influences how much the sunlight heats up the Earth.
Students demonstrate that the angle at which the sunlight hits the Earth is related to the tilt of the Earth’s rotational axis compared to the Earth’s orbit around the Sun.

The purpose of this task is to identify the structure in the two algebraic expressions by interpreting them in terms of a geometric context. Students will have likely seen this type of process before, so the principal source of challenge in this task is to encourage a multitude and variety of approaches, both in terms of the geometric argument and in terms of the algebraic manipulation.

In this lesson, students will investigate the miraculous process of air and water combining with seeds, soil, and sunlight to create nearly all the food we eat. Extension activities can take this a step further by encouraging kids to track growth rates of different seeds in an observation journal. Includes place-based connection, activity instructions, extension activities, songs, and vobaulary list.

NGSS: Partially meets 2-LS2-1, 1-LS1-1

Common Core: W.2.7, W.2.8, and MD.K, MD.1, MD.2.1, MD.3.3, MD.4.4, MD.5 with extension activities.

Time: 45 minutes

Materials: "One Bean" book or other book about plant germination, clear plastic cups, paper cups, paper towels, seeds, and water.

The high school earth and physical science unit moves through an exploration of tectonic plates, why and how they move, and the earthquakes that they cause. As the final project, teams learn about Early Warning Systems for earthquakes and how they have saved millions of lives in other countries. Teams take on a population in Oregon and design a ShakeAlert system to give them the seconds required to prepare for a mega earthquake.

The purpose of this task is for students to select 2 numbers from a set that sum to 5 (or any other number).

As one of literature's most iconic figures, both Shakespeare's plays and poetry provide an interesting glimpse into a variety of essential themes. In this lesson, students will examine how Shakespeare used the sonnet tradition to enhance his stagecraft by performing a scene from his play Romeo and Juliet.

In this scavenger hunt games students are given the task of finding and identifying real-world shapes in their environment.

The CyberSquad must divide 35 candies evenly among seven gargoyles in this video segment from Cyberchase.

In this video segment from Cyberchase, Jackie shows Buzz, Delete and Harold how to deal out rounds (or sets) of objects to solve a problem.

Student readings review the origins of the AK-47, the 10-year federal ban on assault weapons, President Obama's views on guns, and the NRA's political clout. Discussion questions and an inquiry-oriented plan for "constructive controversy" follow.
