Mathematical Relationships
Young scholars practice graphing a linear equation and a parabolic equation. They work cooperatively to select numbers, including fractions, which they will put into ordered pairs. Students explain their process to the class, discussing...
Curated OER
Water and Land 207
Students examine maps of different projections, mathematically calculate distortions, and note the advantages and disadvantages of each map. They study the different maps and transfer the map to graph paper.
Curated OER
Parabolas Exist Where?
Young scholars recognize how parabolas are used in architecture and calculate a constant of variation.

Comparison Shopping—Unit Price and Related Measurement Conversions II
Which rate is greater and by how much? Pupils continue to compare rates to solve problems in the 20th portion of a 29-part series. Rates are presented in a variety of representations either using the same representation or different...
Bowland
Fruit Pies
Scholars use formulas for the area of a circle and the area of a rectangle to determine the number of pies a baker can make from a particular area of dough. They must also take into account rolling the remaining dough into a new sheet.

Patterns in the Distribution of Lactase Persistence
We all drink milk as babies, so why can't we all drink it as adults? Examine the trend in lactase production on the world-wide scale as science scholars analyze and interpret data. Groups create pie charts from the data, place them on a...
Cornell University
Beam Focusing Using Lenses
Explore optics using an inquiry-based experimental approach! Young scholars use a set of materials to design and build a unit capable of focusing a beam of light. They experiment with different lenses to determine the best approach to...

If You Can't Predict the Weather, How Can You Predict the Climate?
Why is the weather man wrong so often? Young climatologists discover how chaos rules both weather and climate through a math-based activity. Using an iterative equation, the class examines how small day-to-day weather events total up to...
Population Connection
The Peopling of Our Planet
How many people live on the planet, anyway? The first resource in a six-part series covers the topic of the world population. Scholars work in groups to conduct research and make population posters after learning about the global...

Modeling a Context from Data (part 1)
While creating models from data, pupils make decisions about precision. Exercises are provided that require linear, quadratic, or exponential models based upon the desired precision. 
Inside Mathematics
Marble Game
Pupils determine the theoretical probability of winning a game of marbles. Individuals compare the theoretical probability to experimental probability for the same game. They continue on to compare two different probability games.
National Academy of Sciences
Lights at Night Webquest
Help learners find ways to become more efficient energy consumers. To start, individuals research how different countries address energy efficiency and then analyze their own carbon footprint. They use their research to identify ways to...
