This is a JiTT exercise in which students apply introductory-level macroeconomic analysis to the question of how large the stimulus package put forward to Congress in early 2009 needed to be to close the recessionary gap facing the U.S. economy at that time. In particular, this exercise asks students to bring together the concepts of potential and actual GDP, recessionary gaps, fiscal policy, spending and taxing multipliers, and effects of changes in aggregate spending on employment and output.

This model-eliciting activity (MEA) challenges students to develop ideas about center and variability when making decisions based on data. Students examine data on departure delays for five airlines flying out of the Chicago O'Hare airport. The task is to develop a model to determine which airline has the best chance of departing on time. Students write a report that identifies the best airline and the reasoning behind their decision.

This model-eliciting activity has students create rules to allow them to judge whether or not the shuffle feature on a particular iPod appears to produce randomly generated playlists. Because people's intuitions about random events and randomly generated data are often incorrect or misleading, this activity initially focuses students' attention on describing characteristics of 25 playlists that were randomly generated. Students then use these characteristics to come up with rules for judging whether a playlist does NOT appear to be randomly generated. Students test and revise their rules (model) using five additional playlsits. Then, they apply their model to three particular playlists that have been submitted to Apple by an unhappy iPod owner who claims the shuffle feature on his iPod is not generating random playlists. In the final part of the activity, students write a letter to the ipod owner, on behalf of Apple, explaining the use of their model and their final conclusion about whether these three suspicious playlists appear to have been randomly generated.This lesson provides an introduction to the fundamental ideas of randomness, random sequences and random samples.

This model-eliciting activity has students determine how to create a fair judging scheme for a paper airplane contest while considering both the most accurate paper airplane and the best floater. Students are given a sample of data that includes multiple flights of paper airplanes by three different pilots. Each team writes a report describing how their judging scheme can be implemented by the judges of the contest. This activity could serve as an introduction to ideas of central tendency and variability. It can also set the stage for understanding the correspondence between data sets and their graphical representations. Alternatively, the activity could be the basis for student introduction to analysis of variance.

This is a version of the time-tested lab where students roll a ball off a table top and use kinematics in two dimensions to try to predict where the ball will land. While many versions of this lab have been previously published, in this version students determine the uncertainty of all measurements and uncertainty of their prediction. The techniques and vocabulary are consistent with the Introduction to Measurement packet.

This investigation is to help reinforce the idea that a mixture can be taken apart by physical means. It will be set up as a contest in which students will have 3 hours of class to separate as much pure substance as they can. These will be broken into percentages based on purity and the amount they have been able to separate. There is no procedure written so students have a completely open and inquiry based activity.

Students use a microphone and Vernier LabQuest to record the sound of a finger-snap echo in a 1-2 meter cardboard tube. Students measure the time for the echo to return to the microphone, and measure the length of the tube. Using their measurements, students determine the speed of sound. While other authors have produced similar labs, this version includes uncertainty analysis consistent with effective measurement technique as presented in the module Measurement and Uncertainty.
