This pathway provides an introduction to cellular mechanisms of transport, including a comparison of passive and active mechanisms. For a deeper look at this topic, we recommend the pathway Structure and Function of Plasma Membranes from the OpenStax textbook Biology for AP® Courses.

With an overview of topics related to chemical equilibrium, this site provides a foundation to a study of thermodynamics and energy. The site specifically addresses free energy and the Gibbs function.

Adafruit founder Limor Fried and virtual reality designer Nat Brown show how simple logical circuits underlie everything your computer does. [4:44]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

Students explore the definition of a function by playing an interactive game called "Club Function." The goal of the game is to be in the club! With students each assigned to be either a zebra or a rhinoceros, they group themselves according to the "rules" of the club function. After two minutes, students freeze in their groups, and if they are not correctly following the rules of the club function, then they are not allowed into the "club." Through this activity students come to understand that one x-coordinate can only have one corresponding y-coordinate while y-coordinates can have many x-coordinates that correspond to it.

Describes the structures associated with the large intestine. Gives a good illustration of the microscopic anatomy of the large intestine.

A brief refresher on the Cartesian plane includes how points are written in (x, y) format and oriented to the axes, and which directions are positive and negative. Then students learn about what it means for a relation to be a function and how to determine domain and range of a set of data points.

Discover how the structure of DNA relates to its hereditary function in these videos from the American Masters film Decoding Watson. The first video, "DNA Structure and Function," [2:07] can be used with all middle and high school biology classes. The second video, "Discovering DNA," [0:55] is the Hereditary Material, contains advanced material and is more suited for students i n AP Biology classes. The accompanying classroom activity, appropriate for all students, explores how the building blocks of DNA assemble into a double helix. Additional support materials are available, including handouts, discussion questions and vocabulary.

Watson and Crick knew that there had to be some type of molecule that was important in protein synthesis. That molecule was RNA. This multimedia article includes animations, pictures, video, biographical information, and quiz questions that are accessed by clicking on buttons along the bottom of the page.

In this video segment from NatureScene, observe some methods of plant identification with regards to the diversity of hardwoods at the Congaree Swamp. [3:47]

This lesson will explore the concept of domain and range and their relationship to functions. It is 9 of 13 in the series titled "Domain and Range." Includes short quiz. [2:49]

This resource has links to topics explaining inverse functions. Includes the derivative of an inverse function.

Students further their understanding of the engineering design process (EDP) while applying researched information on transportation technology, materials science and bioengineering. Students are given a fictional client statement (engineering challenge) and directed to follow the steps of the EDP to design prototype patient safety systems for small-size model ambulances. While following the steps of the EDP, students identify suitable materials and demonstrate two methods of representing solutions to the design challenge (scale drawings and small-scale prototypes). A successful patient safety system meets all of the project's functions and constraints, including the model patient (a raw egg) "surviving" a front-end collision test with a 1:8 ramp pitch.

This is a thorough site which contains a glossary of plant/animal cell anatomy terms. Diagrams of both cells are included along with worksheets to label.

This pathway provides an introduction to enzymes, their properties, and how they affect biological reactions. For a deeper look at this topic, we recommend the pathway Metabolism from the OpenStax textbook Biology for AP® Courses.
