Even when we model the dynamics of the abundances of molecules inside biological systems using calculus, it is important to remember that underlying behavior can be apparently random ("stochastic"). Even a deterministic system containing components moving in periodic ways can, at early times, support dynamics that appear disordered. The behavior of systems containing complicated collections of interacting parts can be difficult to predict with accuracy (chaos). Finally, systems can display stochasticity because the outcomes of measurements on quantum systems are indeterminate in a fundamental way. Random processes are modeled using Markov models.

This is a multi-step problem since it requires more than two steps no matter how it is solved. The problem is not scaffolded for the student, but each step is straightforward and should follow from the previous with a careful reading of the problem.

This is a lesson about the motion of a coronal mass ejection, also called a CME. Learners will calculate the velocity and acceleration of a CME based on its position in a series of images from the Large-Angle Spectrometric Coronagraph (LASCO) instrument on SOHO.

An interactive applet and associated web page that demonstrate straight angles (those equal to 180 deg). The applet presents an angle (initially acute) that the user can adjust by dragging the end points of the line segments forming the angle. As it changes it shows the angle measure and a message that indicate which type of angle it is. There a software 'detents' that make it easy capture exact angles such as 90 degrees and 180 degrees The message and angle measures can be turned off to facilitate classroom discussion. The text on the page has links to other pages defining each angle type in depth. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

This activity introduces students to what a digital image is and how it relates to the real world. It involves a simple training exercise on making linear and area measurements using NIH Image software. The activity is part of Exploring the Environment.

Students learn about contact stress and its applications in engineering. They are introduced to the concept of heavy loads, such as buildings, elephants, people and traffic, and learn how those heavy loads apply contact stress. Through the analysis of their own footprints, students determine their contact stress.

In this task students design a plan to conduct a random sample of the students in their school to estimate the proportion of students who think their parents are strict.
In this activity students add and subtract log distances on their Log …
In this activity students add and subtract log distances on their Log Tapes to discover that the corresponding numbers multiply and divide. This will lead them to an experiential understanding of the laws of logarithms.åÊThis is activity B2 in the "Far Out Math" educator's guide. Lessons in the guide include activities in which students measure,compare quantities as orders of magnitude, become familiar with scientific notation, and develop an understanding of exponents and logarithms using examples from NASA's GLAST mission. These are skills needed to understand the very large and very small quantities characteristic of astronomical observations. Note: In 2008, GLAST was renamed Fermi, for the physicist Enrico Fermi.

This hands-on project is an impactful way to show students how truly immense our solar system is! You get to decide if you want your model to show scale planet sizes or the scale distances between planets. You can combine a planet-size model of one scale with a distance model of another scale. But if you want size and distance to be the same scale, you’ll need to spread your model across at least half a mile! Specific directions on how to calculate size/distance scales are included.
