This activity is a small-group activity that makes students learn the subject matter of aqueous solutions (colloids, suspensions) and phase changes by writing a children's book. Learning by teaching.

Spreadsheets Across the Curriculum/Geology of National Parks module. Students use the geometric mean and multiplicative standard deviation to examine the right-skewed distribution of nutrient concentrations in water-quality data at Mammoth Cave National Park.

This inquiry lab activity involves students working to understand that sound is made from vibrations.

This activity will expose students to the local fish in their lakes. The students will be asked to identify, sort, and classify local fish.

This example engages students in a simple simulation of specialization and division of labor. All that is needed are staplers and some paper.

The students are to calculate the specific heat of three metal objects. Then they are to determine the type of metal.

This activity allows students to brainstorm investigable questions, conduct an experiment, and communicate the results related to our invertebrate animal study; specifically sponges and absorption. (Lesson is based on an original activity from "Porifera's Porosity", Holt Science and Technology - Animals, Holt, Rinehart, and Winston 2002, pages 50-51.)

In this mini-lab students will use chromatography to compare the mobile phase and the stationary phases of different inks used in marking pens. They will also determine the polarity of the solvents and inks. Finally, the students will use their calculated information to solve a crime.

This activity is an investigation where students explore the properties of color and light, using mixtures of common everyday materials.

After using the historical development of the Standard Model to develop introductory understanding, students link to OPAL and DELPHI data archives from CERN to identify and study the tracks from elementary particles.

This is a simulation for a beginning econometrics course that shows students how heteroskedasticity biases an estimator and why the power of a statistical text is important.

This activity is used to introduce the different properties of states of matter, by testing an unknown substance with household materials to determine which state of matter most closely resembles the material. It also can invole data collection, reasoning, grph making, and presentation of findings.

This activity is a lab investigation where students observe the four states of matter. At the end of the investigation students should be able to know that the differences among the physical states depend on the distance between the atoms or molecules and on the rate of movement of the atoms or molecules. And, that pressure and temperature control these two factors.

This activity models the states of matter and students investigate those states with a balloon/straw rocket.

This whole-class activity will involve students in creating static electricity and developing a model to explain what happens when static electricity is formed from wool, plastic, and a paper clip.

Students will statistically analyze data gathered in reference to the Abraham Lincoln penny.

A news story interviews a woman who claims that it was difficult for her to find employment because she had children. The story is used to examine the concept of statistical discrimination and whether public policy should be used to discourage statistical discrimination in this case.

This activity is a lecture where students learn the basic concept behind stoichiometry, mole ratios.

This activity is a field investigation where students will make stream observations to determine its geologic processes and influence to our local topography.

This activity is a field study where students gather data on a stream based upon their protocol. They will correlate their data with another group and present their results to the class. They will develop and defend in class a new experimental question for a spring study.
