The Disappearing Kelp Forest
Learners observe the effect "El Nino" left on kelp plants and sea urchins. They analyze the data collected by researchers, by graphing it on a TI calculator. Before graphing and analyzing the data, you may want to revisit the events of...

Divisibility Rules Using Scientific Calculators
Young learners apply divisibility rules to determine if a number is a factor of another number. They discuss what numbers are factors of another number and identify patterns using divisibility rules.

The King's Chessboard
Middle schoolers speculate on the better rate of pay: a dollar a day for 10 days, or a penny the first day, two pennies the second, doubling each day for 10 days. Start by listening to the story The King's Chessboard, by David Birch....
Curated OER
A Sweet Drink
Students investigate reaction rates. In this seventh or eighth grade mathematics lesson, students collect, record, and analyze data regarding how the temperature of water affects the dissolving time of a sugar cube. Studetns...
Curated OER
A Day at the Beach
Help learners determine the rate of change for the temperature of sand. They will collect data on the temperature of wet and dry sand over time with a heat lamp overhead. Then make a scatter plot of the data and find a linear model to...
Curated OER
A Steep Hike
Students explore slope. In this middle school mathematics lesson, students analyze and interpret graphs as they investigate slope as a rate of change. Students use a motion detector to collect data as they walk at different...
NASA
Next Generation Spacecraft - Orion
Emergine space engineers discover the area of complex geometric shapes. They find that, just as a spacecraft is composed of many smaller parts, so can polygons be broken into smaller shapes.
Curated OER
Animal Skin
Students investigate the skin surface to body area ratios for different animals. In this seventh/eighth grade mathematics/science lesson, students explore heat transfer between an animal’s body and the environment. Using...
Curated OER
What's My Ratio?
Students investigate ratios of various objects. In this ratios of various objects lesson, students draw pictures on graph paper and then dilate or shrink the image. Students determine the ratio of their pictures. ...
Curated OER
Active Wear
Learners interpret and analyze data. In this middle school mathematics lesson, students conduct an experiment in which they investigate which solar collector, black, white, or silver, absorbs the most heat. Learners examine...

Paying College Tuition
The investigation of exponential equation in the context of increasing college tuition costs is explored through this lessib. Students write exponential equations based on the percent of change of college tuition and use their...
Curated OER
A Wet Welcome Home
Students investigate data collection and analysis. In this Algebra I activity, students create a scatter plot and find the equation of best fit in a simulation of a leaking water pipe.
Curated OER
Linear and Exponential Growth
Young scholars explore the concept of linear and exponential growth. In this linear and exponential growth lesson, students collect data about China's population. Young scholars model the data to determine if it is linear or exponential.
