This activity is a hands on lesson where students will explore high and low air pressure.

The purpose of this task is to assess understanding of how study design dictates whether a conclusion of causation is warranted. This study was observational and not an experiment, which means that it is not possible to reach a cause-and-effect conclusion.

Hodges’ Health Career (Care Domains) Model provides a conceptual framework upon which users can map problems, issues and solutions across four knowledge domains: Interpersonal; Sociological; Scientific; & Political (Autonomy). The public may also be taught to use the model, enabling engagement, understanding and concordance in planning and outcome evaluation.

Brian Hodges' original notes, a resources page and links (800+) are included. Additional material on health informatics and the potential role of visualization in care assessment and evaluation can also be found.

In April 2006 a blog related to Hodges' model was created: 'Welcome to the QUAD':

The blog includes a bibliography and a growing archive of posts that are also tagged. There are plans to create a new website using the content management system Drupal. There is an eclectic mix posts that includes examples of using the domains of the model.

Students review the what they have learned throughout the five lessons in this unit. This includes a review of many types of engineers, reminding students of the various everyday products, structures and processes they design and create in our world.

Students further their understanding of the engineering design process while combining mechanical engineering and bioengineering to create an automated medical device. During the activity, students are given a fictional client statement and are required to follow the steps of the design process to create medical devices that help reduce the workload for hospital workers and increase the quality of patient care.

Students apply the concepts of conduction, convection and radiation as they work in teams to solve two challenges. One problem requires that they maintain the warm temperature of one soda can filled with water at approximately human body temperature, and the other problem is to cause an identical soda can of warm water to cool as much as possible during the same 30-minute time period. Students design their engineering solutions using only common everyday materials, and test their devices by recording the water temperatures in their two soda cans every five minutes.

This activity is a lab investigation where students observe, record, and gather data on the speed, acceleration, constant speed, and average speed of toy cars. This activity allows for futher investigation of speed, time, and distance of objects to calculate speed and acceleration.

This lesson explains the application of relative dating for volcanic features in the ocean.

Students gain first-hand experience on how friction affects motion. They build a hovercraft using air from a balloon to levitate a craft made from a compact disc (CD), learning that a bed of air under an object significantly reduces the friction as it slides over a surface.

Students learn about friction and its effects on motion by building model hovercrafts.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water. This lab asks learners to record measurements and make calculations related to volume, diameter, area, and height. Learners also convert meters into nanometers. Includes teacher and student worksheets but lacks in depth procedure information. The author suggests educators search the web for more complete lab instructions.

This inquiry lab activity allows the students to explore limiting reagents with a simple acid and base reaction.

This activity helps students understand how mixtures are formed. They will make predictions regarding the rate of mixing. Students should report that the variation of heated water and crushed sugar creates the shortest mixing time.

Spreadsheets Across the Curriculum module. Students analyze the percentage of change in the diversity of the US compared to New York City over 20 years.

Every living thing must be able to reproduce and make offspring. Most of us are familiar with how humans and mammals make babies, but do all creatures reproduce in the same way? Do insects, like the beetle, give birth to little insects? Also in: French | Spanish

This is a guided inquiry in which the students determine how a light bulb works.

SSAC Physical Volcanology module. Students build a spreadsheet to examine how magma viscosity varies with temperature, fraction of crystals, and water content using the non-Arrhenian VFT model.

SSAC Physical Volcanology module. Students build spreadsheets to estimate melt density at high temperatures and pressures from the thermodynamic properties of silicates.

This task is designed as an assessment item. It requires students to use information in a two-way table to calculate a probability and a conditional probability. Although the item is written in multiple choice format, the answer choices could be omitted to create a short-answer task.

SSAC Physical Volcanology module. Students build a spreadsheet to examine and apply the Mogi model for horizontal and vertical surface displacement vs. depth and pressure conditions in the magma chamber.
