This activity is designed to help deepen our language and understanding of taking observations. We will also learn that water molecules are in constant motion.

Students will investigate what constitutes a solid and a liquid state of matter. Using the probe, students' misconceptions on states of matter will be exposed. The lab, which uses a cornstarch, water and food coloring mixture, will be explored. The students will determine how that exploration will take place and devise a procedure to determine the state of matter. Students will then, as a group, present their findings to the class. After all the groups have presented their findings, the groups with the same findings will combine and defend their findings to the other group(s) until the class, as a whole, has reached a consensus.

This example is an in-class market simulation conducted with paper cards assigning each student a buyer or seller role and a reservation price. This example is appropriate for both upper and lower division courses. Open Outcry Market was developed by Barry P. Keating at the University of Notre Dame.

A public interest group claims that pharmaceutical companies overstate the costs of developing drugs because they include the foregone earnings from the money invested in drug development. The story can be used to discuss the concepts of opportunity cost and normal profit.

In this biology activity, students will first brainstorm how humans use their hands. They will then conduct a short experiment to determine the importance of the opposable thumb to humans and how it is an important adaptation.

This is a computer and outdoor lab based activity in which students design two bottle rockets that are designed to reach maximum height. Students will calculate maximum height and terminal velocity for each rocket launched.

This activity involves using orienteering to gain understanding of vector addition and finding the resultant vector.

This is a lab activity where the students are using the scientific method to observe the process of osmosis. The students will be writing a formal report with their results.

This activity is a field investigation where students venture out into their own backyard to observe and record data on living things and see how these things change throughout the seasons.

This activity is a field investigation where students will make observations on a chosen location every two weeks for the period of one school year. They will record their observations using a digital camera and a nature journal.

This activity is an introduction to setting up a composting worm bin in the classroom. It is part of a yearlong study on the interaction and influences that living system have on each other.

This activity is a field investigation where students reconstruct parts of Winona's Paleozoic environment through observations of a local outcrop and the application of basic geologic principles.

In this field exploration, student teams (consisting of 3 students) will investigate whetherincandescent, fluorescent or a no light situation will attract the most nocturnal insects.

This quick-lab provides a concrete experience with crystal formation from saturated salt solutions that can help students make solubility problems more relevant to their experience.

This activity is a guided inquiry where students investigate the colors contained within a single marker color and interpret what this means about the sizes of the molecules.

This activity is an experimental investigation in which students use paper helicopters to examine types of variables and how to manipulate variables in experimental design.

This activity is a hands-on lesson that shows how air resistance affects how things move and how air is all around objects.

This write-pair-share activity presents Calculus III students with a worksheet containing several exercises that require them to find partial derivatives of functions of two variables. Afterwards, a series of Web-based animations are used to illustrate the surface of each function, the path of the indicated partial derivative for a specified value of the variable and the value of the derivative at each point along the path.

This activity is a lab where students will be working with chemical changes and reactions. It's a simple activity that can be done with household items.
