Students prepare for the associated activity in which they investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Based on the experimental set-up for the activity, students form hypotheses about the acceleration of the device. Students will investigate how the force on the device changes according to Newton's Second Law. Different types of acceleration, including average, instantaneous and constant acceleration, are introduced. Acceleration and force is described mathematically and in terms of processes and applications.
The tutorial examines basic exponential graphs and their properties. Students learn about the mathematics concepts through examples with detailed solutions.

Explore how relationships such as distance and time, velocity and time, etc. can be expressed with function notation. Assess learning with a quiz. [1:52]
Here we look at arithmetic sequences and relate them to recursive and explicit formulas. Students watch a video tutorial. [8:48]
This StudyCard stack teaches and tests on the exponential function. Shows connection between the function parameters and the resulting geometric behaviors of the exponential function. Use with Foundations for College Mathematics, ch. 6.1.
Do you know which foods have lots of calcium for your bones? How do your bones and muscles work together? What are you doing to keep your muscles strong? Students are exposed to 10 activities that will help them address the aforementioned questions and more!
In this video students will learn about the different kinds and functions of stem cells, and about the medical possibilities and controversies surrounding stem cell research. [10:12]
Students act as if they are biological engineers following the steps of the engineering design process to design and create protein models to replace the defective proteins in a child’s body. Jumping off from a basic understanding of DNA and its transcription and translation processes, students learn about the many different proteins types and what happens if protein mutations occur. Then they focus on structural, transport and defense proteins during three challenges posed by the R&D; bio-engineering hypothetical scenario. Using common classroom supplies such as paper, tape and craft sticks, student pairs design, sketch, build, test and improve their own protein models to meet specific functional requirements: to strengthen bones (collagen), to capture oxygen molecules (hemoglobin) and to capture bacteria (antibody). By designing and testing physical models to accomplish certain functional requirements, students come to understand the relationship between protein structure and function. They graph and analyze the class data, then share and compare results across all teams to determine which models were the most successful. Includes a quiz, three worksheets and a reference sheet.
