While the task as written does not explicitly use the term "unit rate," most of the work students will do amounts to finding unit rates. A recipe context works especially well since there are so many different pair-wise ratios to consider.

In this video, learn from chemical engineers Laura and Wade about what it takes to become a chemical engineer and why it's a great career. Find out how chemical engineers do things like save the environment, take waste and make it useful, and solve real-world problems every day.

ABOUT THE SCIENCE
What do disposable diapers, soda, hydrogen fuel cells, aluminum, penicillin and snowboards have in common? They were all invented or further processed by a chemical engineer!
Are you someone who likes to solve problems? Do you like making something new? Do you care about the environment? If so, being a chemical engineer might just be for you!
As an engineer in this field, you get to apply chemistry to the industrial process to make things. It takes technology, innovation, and ideas to help generate an end result.
An example of this is through making textiles out of weeds! As a chemical engineer, first you would put the weeds through a processing system, have them pulped, put through an extruder to create a fiber, and then voila! You can use that to create textiles. To ensure chemical engineers are being friendly to the environment, their decision making always considers renewable resources.

Science Background:
Encourage students to be creative in their problem-solving strategies, within the scope of the rules. Students will discover that any strategy that increases the amount of heat or increases the surface area of the ice will result in a faster melt. You might ask students how they would change their strategies if the ice cube were doubled in size, if they were melting a large block of ice, or if they were melting an equal mass of ice chips.
Materials: one ice cube for each student
Directions:
Melt an ice cube as fast as you can, using the following three rules:
1. You cannot put the ice cube in your mouth
2. You must collect as much of the melted water as possible (decide how you will collect the water)
3. You can only use what is at your desk right now

Cool Kid Facts gives your child access to educational videos, pictures, quizzes, downloadable worksheets, and infographics. They can use these to learn about geography, history, science, animals, and even the human body.

Students learn the meaning of preservation and conservation and identify themselves and others as preservationists or conservationists in relation to specific environmental issues. They use Venn diagrams to clarify the similarities and differences in viewpoints. They see how an environmental point-of-view affects the approach to an engineering problem.

These games support student development of the concept of ordered pairs as they play to win each game.

This lesson introduces students to the idea of biomimicry or looking to nature for engineering ideas. Biomimicry involves solving human problems by mimicking natural solutions, and it works well because the solutions exist naturally. There are numerous examples of useful applications of biomimicry, and in this lesson we look at a few fun examples.

This week, Stan Muller teaches you the basics of copyright in the United States. Copyright law is territorial, so we're going to cover the system we know the most about, and that's the US. Stan will talk about what kind of ideas can be copyrighted, who can get a copyright, and what protections the copyright grants. We'll also talk about the always contentious and seemingly ever-growing term of copyright. Stan will also teach you about the low bar for creativity, which means that original work doesn't have to be all that original, and he'll also touch on the problems with copyright in the modern world.

Copyright & Creativity for Ethical Digital Citizens is a full K-12 suite of resources for teaching copyright, fair use, public domain, and Creative Commons. They have free resources for educators, which include:
• in-class lesson plans
• plug-n-play lesson slides
• independent learning videos
• visual aids
• a professional development course for teachers
All resources were developed on a nonprofit basis with input from independent educators, academic copyright experts, and online civil liberties advocates.

Stan Muller teaches you a few things about copyright enforcement, and talks about the exceptions to copyright enforcement. While there are several, the one you've probably heard of is Fair Use, and it's a pretty tricky one. We'll try to explain it, and teach you just why fair use is so loosey goosey.

This lesson takes advantage of students' interest in music and audio sharing. Students investigate multiple perspectives in the music downloading debate and develop a persuasive argument for a classroom debate.

Students investigate how and why copyright law has changed over time, and apply this information to recent copyright issues, creating persuasive arguments based on the perspective of a particular group.

In our Avoiding Plagiarism module, we gave you tips for citing, quoting, and incorporating various sources into your writing projects. However, depending on what types of sources you use, you may also have to consider copyright and fair use laws. For example, if you want to use someone else's photo or song in one of your own projects, you'll need to make sure you have the legal right to do so. In this tutorial, you'll learn about the copyright protections that apply to work posted online, including images, text, videos, and more. You'll also learn about the rules that determine which of these resources you can use, and how you can use them.

DESCRIPTION
Copyright and fair use are crucial topics for educators. In today’s digital world, copyright and fair use are also directly relevant to activities that students engage in virtually every day. This short course aims to make these concepts clear and accessible to educators. Completing this course should give educators the background they need to feel comfortable teaching these concepts to students using Copyright and Creativity for Ethical Digital Citizens, our free suite of K-12 teaching resources.

OBJECTIVES
At the end of this course, you’ll be able to:

Understand the purpose of copyright and its basic rights.
Understand the limitations of copyright, including fair use.
Understand how to acquire and share media in lawful and ethical ways.
Be prepared to apply copyright and fair use to project-based learning situations, including knowing how to help students find creative work that is free and legal to re-use and share.

Corals are beautiful, diverse and complex structures. Nearly everyone knows about Coral Reefs, but do you know what they actually are...? Coral Reefs are vital animals that provide the foundation for the richest diversity in the ocean. Explore the important role that corals have for the oceans worldwide, and understand how our small choices can have a powerful impact on life in the ocean.
