This activity is an extension activity following a unit study on mixtures and solution. Students will use variables to create a unique cola formula and present their findings.

This Chemistry experiment investigates physical changes, solutions, supersaturated solutions, and states of matter.

At the beginning of a DNA, DNA replication, and mitosis unit, students are given a short science news article summarizing a recent research paper. This assignment links the article to figures and key techniques from a related journal article, requiring students to apply and transfer the knowledge they gained in the unit.

Spreadsheets Across the Curriculum Module. Students build spreadsheets to estimate discharge for a culvert using the Manning equation, and to estimate culvert size, given a specified discharge.

Spreadsheets Across the Curriculum/Geology of National Parks module. Students work with a color-coded conditional-formatted spreadsheet map to work through a USGS report applying a coastal vulnerability index, examining real data related to relative sea-level change for different areas of the Californian coas,t including Point Reyes National Seashore.

This activity is an investigative introduction to mapping. Students create maps and determine important map features.

This earth systems field lab begins with an in-class guided inquiry experience which uses Minnesota Geological Survey 3-D maps of the upper Midwest to determine where they believe glaciers may have had an influence. They will determine this by looking at landscapes and compiling their own evidence from the maps. They will also offer evidence for a hypothesis they generate which involves the direction that the glacier was traveling.

This activity is a classroom investigation where students test the impact track shape has on vertical distance of a rolling object.

In this problem, students consider the benefits of reduced tray usage in school cafeterias by comparing the cost savings of having to clean fewer trays against the opportunity cost of increased labor and energy costs to clean the cafeteria after meals.

MarketSim helps students understand the functioning of markets by having them become consumers and producers in a simulated economy. There are two versions, both implemented over the internet. Jeremy's market is a consumer barter market. Adam's market introduces firms and money. MarketSim received funding from the National Science Foundation. The simulation is most appropriate for economics principles courses. The principle developers are Tod S. Porter and Kriss Schueller at Youngstown State University.

This activity will take complex molecules and polyatomic ions the students have learned and construct them out of marshmallows and redhots. This develops understanding in VESPR structures and hybrid molecules.

This lesson is a classroom activity where students learn about paleontologist Mary Anning, briefly learn about sedimentary rock, and complete observation drawings of Platteville Limestone fossils.

This activity is a series of game-like lessons that assist the student in developing the logic skills needed to read mass spectrometer output and formulate the identity of an unknown molecule. As students endeavor to identify the unknown they must apply fundamental chemistry knowledge including formula mass, isotopes, periodic table, relative abundance, interpreting graphs, organic chemistry, ionization, bonding rules, and structural formulas. Based on an activity presented by Olaf Runquist, Professor, Hamline University.

In this activity, a six-foot length of nylon rope is suspended at both ends to model a mathematical curve known as the hyperbolic cosine. In a write-pair-share activity, students are asked to make a conjecture concerning the nature of the curve and then embark on a guided discovery in which they attempt to determine a precise mathematical description of the curve using function notation.

Spreadsheets Across the Curriculum module. Students build spreadsheets to find the maximum volume of an open-top box by cut-and-folding a sheet of cardboard.

This is an indoor lab that uses a boat simulation to demonstrate the concepts of mass, volume and density, and their relationship to displacement. It is a problem solving activity that encourages student creativity resulting in a variety of valid solutions.

This is an indoor lab where students design marble runs to test what factors affect the final velocity of a marble.

This activity is a field investigation where students observe, predict, and gather data on steam velocity, erosion, and discharge.

This activity is an inside lab experiment where the students combine primary colored liquids correctly to create a rainbow.

This is a physics lab where students test their reaction time by using the acceleration due to gravity. The use of Excel is introduced in this lab to analyze data.
