Less is best when looking at residuals. Scholars use an interactive to informally fit a linear regression line to data on a scatter plot. The interactive provides a correct best fit line with residuals and correlation coefficient to...

Students explore geography by answering study questions in class. In this plate tectonics lesson, students identify the earthquake data concerning the country of New Zealand and answer questions regarding the data. Students identify...

Students explore how to draw contour lines from limited data and extend this knowledge to real data sets. They participate in many opportunities from students to assess their own progress and the exercise is completely online.

Space science stars journey through our night sky and take virtual photos of galaxies to investigate simple random samples. Higher math is used to analyze the data collected. Copy the evaluation/assessment questions onto a handout...

Middle schoolers play game to practice numerical skills.

Students simulate the three types of plate boundaries using robots. In this earth science lesson plan, students explain how earthquakes and volcanoes are formed. They collect real-world earthquake data and plot them on the map.

Students explore Earth science by building a model in class. In this tectonic plate lesson, students identify the impact tectonic shifts have on humans and animals and where the plates and faults lie under New Zealand. Students examine...

First graders explore geometry by completing a worksheet in class. In this non-standard measurement unit lesson, 1st graders discuss different techniques for measuring items without the use of a ruler. Students read several short stories...

Students complete a game-like simulation to determine a career and salary. In groups, they collect information and decide what is the "best" city in which to live. They create a monthly budget for their "best" city based on salary from...
