Secondary learners investigate exponential functions in a real-world scenario. They collect data on the temperature of a cooling baked potato, enter the data into lists, and graph the data using a scatter plot before finding an...

Young scholars collect height versus time data of a bouncing ball using the CBR 2™ data collection device. Using a quadratic equation they graph scatter plots, graph and interpret a quadratic function, apply the vertex form of a...

Let's go fishing together. The lesson looks at the giant catfish from two perspectives. Mathematically, pupils develop a scatter plot and a best-fit line for the size, while others take a scientific look at the reasons for their...

High schoolers analyze environmental science data using Math. They do research about renewable energy, gather data, create graphs and interpret their findings. Then the group presents their arguments persuasively using their findings to...

Learners study weather using a graphing calculator in this lesson. They collect data for temperature and relative humidity for every hour over a day from the newspaper, then place the data in their handheld calculator and examine it for...

Young scholars analyze line plots. In this weather lesson using real NASA data, students discuss how weather affects the way the Earth is heated by comparing different line plots.

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

How much plastic do manufacturers use to create water bottles each year? The class explores the number of water bottles used throughout the years to determine how many consumers will use in the future. Class members compare different...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Seventh graders use the scientific method, to observe, record and analyze the data they gathered. They make observations using their five senses. Students compare, contrast and draw conclusions based on the observations and data...
