Students apply concepts of disease transmission to analyze infection data, either provided or created using Bluetooth-enabled Android devices. This data collection may include several cases, such as small static groups (representing historically rural areas), several roaming students (representing world-travelers), or one large, tightly knit group (representing urban populations). To explore the algorithms to a deeper degree, students may also design their own diseases using the App Inventor framework.

Students engage in an interactive "hot potato" demonstration to gain an appreciation for the flow of electrons through a circuit. Students role play the different parts of a simple circuit and send small items representing electrons (paper or candy pieces) through the circuit.

Students apply several methods developed to identify and interpret patterns to the identification of fingerprints. They look at their classmates' fingerprints, snowflakes, and "spectral fingerprints" of elements. They learn to identify each image as unique, yet part of a group containing recognizable similarities.

The goal of this task is to look for structure and identify patterns and then try to find the mathematical explanation for this. This problem examines the ''checkerboard'' pattern of even and odd numbers in a single digit multiplication table.

This simple conceptual task focuses on what it means for a number to be a solution to an equation, rather than on the process of solving equations.

In this activity, students will learn how water can be polluted by algal blooms. They will grow algae with different concentrations of fertilizer or nutrients and analyze their results as environmental engineers working to protect a local water resource.

This task provides a context where it is appropriate for students to subtract fractions with a common denominator; it could be used for either assessment or instructional purposes.

This task allows students to reason about the relative costs per pound of the two fruits without actually knowing what the costs are. Students who find this difficult may add a scale to the graph and reason about the meanings of the ordered pairs. Comparing the two approaches in a class discussion can be a profitable way to help students make sense of slope.

Peer instruction may offer some of the richest opportunities for metacognitive teaching. Reciprocal (peer) teaching forces the instructor to use a whole series of metacognitive processes such as determining what the learner already knows, deciding what is to be taught/learned and how; monitoring comprehension and evaluating the outcome in terms of increased comprehension, which in turn encourages the instructor to reflect upon his or her own thinking processes. By asking the students to defend their answer to a question to another student you are, in effect, moving the role of "teacher" to the students.

This word problem requires students to use addition and subtraction and think about money.

This activity is a lab where students will be working with chemical changes and reactions. It's a simple activity that can be done with household items.

Spreadsheets Across the Curriculum module/Geology of National Parks course. Students calculate percentages and percent differences to compare various measures of fumaroles, mud pots, hot springs and geysers in this introduction to hydrothermal features at Yellowstone NP.

Students explore the concepts of center of mass and static equilibrium by seeing how non-symmetrical objects balance. Using a paper cut-out shape of a parrot sitting on a wire coat hanger, they learn that their parrot exists in stable equilibrium — it returns to its balancing point after being disturbed. The weight of its tail makes the parrot balance upright. Give the parrot a push, and she knocks off balance, but swings back and forth until coming to rest in balance again.

Students find the profit-maximizing level of output for a perfectly competitive firm and check the shut-down condition for two different prices.

This activity teaches students about the periodic table and how element properties can be predicted through periodic trends.

Students investigate how different riparian ground covers, such as grass or pavement, affect river flooding. They learn about permeable and impermeable materials through the measurement how much water is absorbed by several different household materials in a model river. Students use what they learn to make recommendations for engineers developing permeable pavement. Also, they consider several different limitations for design in the context of a small community.

What if educators could see what a student knows, what they need to know, and how to motivate them...all by looking at a map? Danny Hillis, Chairman and Co-Founder of Applied Minds, asks us to imagine a learning map that goes beyond existing search engines to show educators just that.

In this activity, students are assigned different alleles of the gene for phenylalanine hydroxylase to research using OMIM (Online Mendelian Inheritance in Man). They are then asked to both explain and illustrate how this mutation may cause the disease phenylketonuria (PKU).
