Building trigonometric basics here will last a mathematical lifetime. Learners expand on the previous activity in a 36-part series by examining relationships between the sine and cosine of complementary angles. They also review the...

Does a linear or exponential model fit the data better? Guide your class through an exploration to answer this question. Pupils create an exponential and linear model for a data set and draw conclusions, based on predictions and the...

Landforms in Beacon Valley, Antarctica, where there is no snow, bear a striking resemblance to landforms found on Mars. Scholars identify landforms found in Beacon Valley through analysis of topographic maps in the activity. They then...

Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...

There is power in spreadsheet formulas and learners use this power to model quadratic data. Given a scatterplot of a parabola, pupils create formulas in a spreadsheet to populate the data. The formulas they use lead to an understanding...

Many phenomena in life are periodic in nature. A task-based lesson asks scholars to explore one of these phenomena. They collect data showing the sunrise time of a specific location over the period of a year. Using the data, they create...

The Silk Road connected the European, Middle Eastern, and Asian worlds. It also helped create the modern trade world. An analysis activity makes the importance of this Chinese innovation clear by asking participants to evaluate trades...

The term periodic in periodic table has meaning. Young scientists view a video to learn about the periodic table and then use the provided resources to create their own tables. They focus on patterns of the chemical properties of each...

Ninth graders examine the application of statistical sampling, data collection, analysis, and representation that exists in schooling and teenage lifestyles in Japan and the United States.

Not all species can survive in all habitats. Using specific criteria, learners assess the fitness of a local habitat to a specific species. They collect data and suggest enhancements to create a suitable habitat for their chosen species.

Daily routines not only help to manage classrooms, they can also provide students with rich opportunities for learning. This activity supports young learners in developing their number sense by counting up the school days on a class...
