This activity is a indoor lab where student gather data about centripital acceleration and write up a lab based on their findings.
Student groups compete to design a process that removes the most iron from fortified cereal. Students experiment with different materials using what they know about iron, magnets and forces to design the best process for removing iron from the cereal samples.
Students teams use a laparoscopic surgical trainer to perform simple laparoscopic surgery tasks (dissections, sutures) using laparoscopic tools. Just like in the operating room, where the purpose is to perform surgery carefully and quickly to minimize patient trauma, students' surgery time and mistakes are observed and recorded to quantify their performances. They learn about the engineering component of surgery.
Spreadsheets Across the Curriculum module. Students build spreadsheets to explore conditions that lead to chaotic behavior in logistic models of populations that grow discretely.
This activity examines the characteristics of light. Students demonstrate that light travels straight and does not bend around an object.
This video segment adapted from NASA describes the basic characteristics of our star, the Sun.
Students use balloons to perform several simple experiments to explore static electricity and charge polarization.
Similar to how Charlotte uses her web to communicate, students create webs for short messages. They learn how spiders create their webs, and about the different types of webs they make. With this knowledge, students design and create their own webs and incorporate messages.
In this video segment adapted from NOVA, scientists are on the hunt for tornadoes. Using Doppler radar, they gather data in the hopes of solving the mystery of how tornadoes form.
The purpose of the task is to connect properties of fractional exponents with ordering of real numbers. One can place the numbers on the number line to emphasize this.
This activity is a lab where students make qualitative and quantitative observation on a chemical change. They will see that gases have mass in accordance with the conservation of matter.
Spreadsheets Across Curriculum module. Students build spreadsheets to compare the time course of a reaction that goes to completion to that of an equilibrium reaction.
This activity is an inquiry-based investigation where students discover the indicators of chemical reactions (endothermic and exothermic) by collecting data and using that data to develop a testable question for further experimentation.
This problem includes a percent increase in one part with a percent decrease in the remaining and asks students to find the overall percent change. The problem may be solved using proportions or by reasoning through the computations or writing a set of equations.
This task presents a real world situation that can be modeled with a linear function best suited for an instructional context.
This task is intended strictly for instructional purposes with the goal of building understandings of linear relationships within a meaningful and, hopefully, somewhat familiar context.
This activity provides a demonstration and lab exploration of one of the main "building blocks" of the periodic table of elements: chlorine. During the lab, students compare physical and chemical properties of chlorine compounds.
In this task students use different representations to analyze the relationship between two quantities and to solve a real world problem. The situation presented provides a good opportunity to make connections between the information provided by tables, graphs and equations.
Working in engineering project teams, students evaluate sites for the construction of a pyramid. They base their decision on site features as provided by a surveyor's report; distance from the quarry, river and palace; and other factors they deem important to the project based on their team's values and priorities.
This task suggests methods of introducing and continuing choral counting in the classroom.
