Spreadsheets Across Curriculum module/Introductory chemistry course. Students build spreadsheets to examine unit conversions between the metric and English systems. Spreadsheet level: Beginner.

This activity is designed to further develop students' understanding of the characteristics of insects. Students will be sorting insects from non-insects that they themselves find in a sample of pond water.

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.

A "Just in Time Teaching" question about he scientific method with follow-up class room activities and an exam question.

Spreadsheets Across the Curriculum/Geology of National Parks Collection. Students create a histogram to examine the time between geyser eruptions of Old Faithful, Yellowstone National Park.

Children will investigate leaves by observing, playing a game, sorting and journaling in a science notebook.

In this listening comprehension exercise, students will complete a questionnaire based on a podcast on the topic of dyslexia. Students will listen to the podcast at the French website Neopodia and answer comprehension questions in complete sentences in French.

"Earth's Energy Budget and the Greenhouse Effect" is a lab activity in which students use computers and scientific applications software to access, display, describe, analyze, and interpret global, climate-related data sets related to the earth's energy budget and the greenhouse effect.

This investigation is a lab where students find out if mass is created or destroyed in a closed system. Students will balance the chemical equation to re-enforce their findings.

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.

This activity is an on-line research activity in which students research different Minnesota lakes and determine their physical characteristics, chemical characteristics, and the overall health of the lake.

This activity is a guided inquiry or demonstration where students investigate elastic potential energy and gravitational potential energy and interpret their findings as related to Newton's Laws of motion.

An ILD to help demonstrate the Law of Diminishing Marginal Returns using an experiment.

This activity can be used to teach concepts how different densities of liquids can be layered and/or how the salinity of water affects the movement of ocean water.

In this jigsaw activity, students of intermediate-level French will divide into five groups to become experts on each of the five biodiversity questions featured on the Curiosphere website. They will proceed to explain their assigned aspect of the issue to a small group of students.

This activity is a group activity where students investigate leaves and sort them based on established criteria.

This is a classroom activity where students will make plant rubbings and plant pressings of Minnesota plants.
