Students are introduced to the concepts of graywater and water reuse within households. They calculate the amount of used water a family generates in one day and use a model of home plumbing to find out how much graywater is produced in...

Students are introduced to our planet's structure and its dynamic system of natural forces through an examination of the natural hazards of earthquakes, volcanoes, landslides, tsunamis, floods and tornados, as well as avalanches, fires,...

To get a better understanding of complex networks, students create their own, real social network example by interacting with their peers in the classroom and documenting the interactions. They represent the interaction data as a graph,...

This electrical engineering activity uses a TI graphing calculator to analyze AC circuits including sine waves, capacitance and inductive reactance, solving series AC circuits, and RMS calculations.

In this activity, students' use a motion detector to the measure the reaction time of students. They graph the data from trials conducted in the class and analyze trends. They then calculate drop distance from reaction time.

The focus of this series of lessons is to engage students in an exploration of the world around them. The emphasis is on inquiry as students learn about the earth, sun, light, shapes and more.

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 weight added incrementally to an object affects the amount of friction...

Students are introduced to measuring and identifying sources of air pollution, as well as how environmental engineers try to control and limit the amount of air pollution. In Part 1, students are introduced to nitrogen dioxide as an air...

[Free Registration/Login Required] Using the average acceleration formula, calculate the velocity of a falling ball, and then check your answer by dragging the point along the line in the given graph. After the activity, answer one...

Students analyze and begin to design a pyramid. Working in engineering teams, they perform calculations to determine the area of the pyramid base, stone block volumes, and the number of blocks required for their pyramid base. They make a...

In this lab activity, students investigate the effects of changing force on the acceleration of a lab cart testing Newton's Second Law of Motion. They will use distance and time to calculate velocity and create a graph representing their...

Students will conduct a field investigation to learn about the environment. They will observe biotic and abiotic factors of an ecosystem. Students can use the CBL 2 and a temperature probe to collect data and a graphing calculator to...

Students learn about the many types of expenses associated with building a bridge. Working like engineers, they estimate the cost for materials for a bridge member of varying sizes. After making calculations, they graph their results to...
