In this exercise, students identify and draw slices through an ice cream cone, a pyramid, and a beverage six-pack.

In this field investigation, students will identify and determine the population size of snails in an aquatic environment.

This sites provides three interactive games related to social class and personal possessions indicative of class.

This lesson will extend the learning on rocks with the Foss kit, Pebbles, Sand, and Silt to include soil. Students will perform the soil sifting activity like the one designed for rocks in the Foss it. Through their work, students will complete a Venn diagram of soil and rocks as a class.

Students will explore with solids and liquids to discover what density is. Students will be involved in small group experiments and a full group experiment. Observing, predicting, exploring and discovering are all included in this lesson.

This guided inquiry lesson allows students to make explore with materials and draw conclusions if they are a solid or liquid.

This activity is a classroom activity where the students move through learning stations to explore the properties of solids and liquids.

This is a lab activity where students will investigate solubility or miscibility of eight substances with water.

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.
