This lesson unit is intended to help students judge the accuracy of two different approximations to a particular linear relationship. Students will compare two linear functions as approximations to the relationship between Celsius and Fahrenheit temperature and consider under what circumstances each of the approximations may be reasonable.

How can you use the Engineering Design Process to access a geographically inaccessible location to deliver supplies?

As diseases become stronger in nature, currently available antibiotics are no longer strong enough to suppress and cure said diseases. Therefore, what factors contribute to diseases becoming resistant to drugs and what public policies should be developed around them?  In this problem-based learning module, students will work with partners or in groups to first assess the increasing problem of drug-resistant diseases and the toll they are taking on the American public. Additionally, students will work to investigate what hospitals and lawmakers are doing to address this problem. Once students understand and are familiar with the current state of affairs, they will then work to further understand and research exactly why this issue needs to be brought to the attention of the general public, in order to promote change to current hospital procedures and policies. Further, students will determine the current political climate and support (or lack thereof) for policy, and will analyze the interest in keeping, changing or removing said policies altogether. Once the group has a full understanding, students will then work to determine their position on the issues surrounding antibiotic resistant diseases and the policies associated with these diseases. As soon as the group reaches a consensus, students will work to research and determine a professional way in which to present their goals and objectives for curbing the issue of drug-resistant diseases.

CK-12's Texas Instruments Algebra I Teacher's Edition Flexbook allows an Instructor to teach students to better utilize a graphing calculator in understanding the fundamental concepts of algebra.

CK-12 Foundation's Algebra I Teacher's Edition FlexBook complements CK-12's Algebra I Student Edition. The solution and assessment guides are available upon request.

In this four part series, we visit the classrooms of two partner teachers who plan all their lessons together but have totally different styles inside the classroom. See the same lesson unfold in each class, the class structures used by each teacher, and the group work formats used by each.

This lesson is for ABE students at a level D-E Reading level to practice identifying key points in video and text and analyzing the causes and effects of social issues, and identifying solutions to these problems. By watching two short videos and reading materials on the effects of lead exposure and on the specific drinking water crisis in Flint, MI, students will examine key issues, analyze the problem and its causes, identify approaches to solving this problem and ones like it in other locations, and apply this approach to other scenarios that are relevant to their immediate lives.

This is a free textbook teaching introductory statistics for undergraduates in Psychology. This textbook is part of a larger OER course package for teaching undergraduate statistics in Psychology, including this textbook, a lab manual, and a course website. All of the materials are free and copiable, with source code maintained in Github repositories.

Antibiotics save people’s lives...and make bacteria stronger and more likely to kill us.  What is the best practice to balance these conflicting issues? In this problem-based learning module, the students will be evaluating real-life medical situations in conjunction with actual staff at those institutions and offering action plans to be ‘implemented’ there.  In order to accomplish this, the science unit will be interlocking with social studies and a language arts unit that will have them identifying target audiences and sculpting a way to present their findings.  This unit has the potential to be a full problem-based unit as well as highly interdisciplinary--it’s connected to full units in social studies and language arts which stand alone but can be fully integrated if desired.

In this simulation of a doctor's office, students play the roles of physician, nurse, patients, and time-keeper, with the objective to improve the patient waiting time. They collect and graph data as part of their analysis. This serves as a hands-on example of using engineering principles and engineering design approaches (such as models and simulations) to research, analyze, test and improve processes.

In this structured inquiry activity students will work in groups/ teams to build a balloon rocket of their own design. The rocket will race in one dimension and require that they apply their knowledge of position, time, and velocity.

This activity is a scientific investigation focusing on inquiry after using the Foss Water Kit. The students will pose a question, create a procedure and produce a poster showing their findings.

In this multi-day activity, students explore environments, ecosystems, energy flow and organism interactions by creating a scale model biodome, following the steps of the engineering design process. The Procedure section provides activity instructions for Biodomes unit, lessons 2-6, as students work through Parts 1-6 to develop their model biodome. Subjects include energy flow and food chains, basic needs of plants and animals, and the importance of decomposers. Students consider why a solid understanding of one's environment and the interdependence of an ecosystem can inform the choices we make and the way we engineer our own communities. This activity can be conducted as either a very structured or open-ended design.

This activity is an introduction to the study of birds. Students will gain observation and classification skills.

Try this fun problem! In any group of six people, what is the probability that everyone was born in different months?

This guided inquiry activity, in which ice is used to boil water in a Florence flask, works well in the introductory class to a chemistry or physical science course. The students will learn the difference between observation and inference and apply this understanding to various other situations in which observations and inferences must be made. The students will also use outside sources to try to explain why the activity worked.
