This activity is a field investigation where students gather data on stream health by collecting macro-invertebrates at three different locations and then develop an experimental question through land use and topographic map research to explain differences in water quality.

This activity is a field investigation using science inquiry and problem solving, where small groups of students design their own experiment to determine stream velocity, collect and analyze their data, draw conclusions, and make further inferences based group discussion/collaboration.

Short demonstration on scientific notation by asking students to place numbers on a number line using string and notecards.

This lab and demonstration activity involves students conducting chemical reaction experiments to determine the chemical reaction type and writing balanced equations.

Students learn glacial landforms and create a landform map including a location grid (eg. position A2) and map key.

A POGIL activity regarding cellular respiration with an additional activity regarding the function of NAD+ in redox reactions.

This activity is a lab where students gather data using glass pipettes to understand the concept of precision and data analysis.

During this project, students will be working to cooperatively create a field guide to trees in the neighborhood near the school. In doing so they will be making observations, introduced to tree and plant anatomy and physiology, and will learn how to make and use dichotomous keys.

Many people do not like spiders and consider them pests. However, spiders provide a service to humans. They eat many of the insects that bother people. In this 7th grade life science activity, students will study 4-6 spider webs and discover what and how much spiders eat. They will identify the spiders building the webs, collect data and make observations related to the webs and what the spiders eat. They will use the information to develop a conclusion.

This lab is an activity designed to demonstrate to students the importance of the proper use of lab equipment. Also to demonstrate how math can be used as a tool for analysis of data.

While working in groups to facilitate peer tutoring, students manipulate a hands-on, physical model to better comprehend several characteristics of subduction zone earthquakes.

A free online simulation that demonstrated the bull-whip effect, and the complexities of supply chain management, responding to changes in customer demand.

Students experiment and hypothesize about surface tension and cohesion, using water, ground black pepper, liquid soap, and other household products.

Students are directed to read through a Web-based tutorial on Symmetry and Tilings in the form of an short and colorful article entitled Tilings and Tesselations; afterwards, they answer several questions on tilings (tessellations), tiling terminology, types of symmetry (isometries), periodic tilings and Penrose tilings.

Spreadsheets Across the Curriculum module/Geology of National Parks course. Students work with ratio and proportion and the concept of mole to calculate the number of molecules of ozone in a volume of air from concentration data.

Students carry out a naturalistic observation study in order to test the hypothesis that there are sex differences in risk-taking. Students collect and analyze data and prepare APA style research report.

Students use a spreadsheet to compute the hypothetical risk of an Andrew-like hurricane to downtown Miami.

Students use spreadsheets to analyze the reasons why New Orleans has subsided in the past 250 years.

Students are asked to write a letter to the editor of their newspaper to explain their point of view as a seller in a market that is about to experience an increased sales tax rate.
