While building and testing model rockets fueled by antacid tablets, students are introduced to the basic physics concepts on how rockets work. Students revise and improve their initial designs. Note: This activity is similar to the elementary-level film canister rockets activity, but adapted for middle school students.
Show Me the Money
Students learn about the major factors that comprise the design and construction cost of a modern bridge. Before a bridge design is completed, engineers provide overall cost estimates for construction of the bridge. Students learn about the components that go into estimating the total cost, including expenses for site investigation, design, materials, equipment, labor and construction oversight, as well as the tradeoff between a design and its cost.
Does Contact Area Matter?
Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if the amount of area over which an object contacts a surface it is moving across affects the amount of friction encountered.
Drum Roll Please
This lesson gives students hands-on experience making a presentation, and allows them to present and defend their final decision to the class. Students commit to a final decision early in the lesson, then justify that decision. After making their decision they prepare their final presentations.

Electrochemical Detection of Phenol Utilizing a Synthesized Sonogel-carbon Zirconium Oxide
This experiment is designed for senior undergraduate students in an inorganic chemistry course. Students are asked to synthesize a sonogel-carbon electrode that is modified with a ZrO2 sol-gel and to compare the results to those of an unmodified electrode for the detection of phenol.
Teaching Chemical Equilibrium Concepts Using Field-Lab Experiences
This online article describes an inquiry-based experience designed to integrate concepts in water quality and geology for pre-education science students preparing to become teachers at the primary and secondary level. The field and laboratory exercise could be used to effectively introduce equilibrium chemistry in an introductory or environmental chemistry course, and courses for non-majors.
Animation of diode array detection in HPLC
This animation site deals specifically with diode array detection for liquid chromatography. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) are also listed on ASDL. This site requires FLASH version 7 or
The Geometer's Sketchpad - Least Squares
This site provides a java-based demonstration of how a least-squares analysis works. The applet opens with a set of data points with a superimposed line. By clicking and dragging, the user can move the data points and change the slope and/or the y-intercept of the line. The residual error for each data point is shown as a square whose area increases the greater the vertical distance between the point and the line. A total sum-of-squares also is shown. By adjusting the slope and y-intercept, the
This site provides a thoughtful introduction to problem-based learning including an overview of PBL, its history, examples of problems, a discussion of group dynamics, and the role of the instructor in PBL. Be aware that there are broken links on this website (e.g., the resources page).
