A Hovmuller plot is a diagram that visibly displays data patterns from a selected latitude or longitude over a time period. Through a storyline and several samples, students are introduced to a Hovmuller plot of temperature data along a longitude in... (View More) the eastern United States. Students then create salinity and precipitation plots using data from the MY NASA DATA Live Access Server. (View Less)
This is an activity about measurement. Learners will label key points and features on a rectangular equal-area map and measure the distance between pairs of points in order to calculate the actual physical distance on the Sun that the point pairs... (View More) represent. This is Activity 5 of the Space Weather Forecast curriculum. (View Less)
This is an activity about the period of the Sun's rotation. Learners will use image of the Sun from the SOHO spacecraft and a transparent latitude/ longitude grid called a Stonyhurst Disk to track the motion of sunspots in terms of degrees of... (View More) longitude. Using this angular motion measurement, learners will then calculate the sunspot’s angular velocity in order to determine the rotation period of the Sun. This activity requires access to the internet to obtain images from the SOHO image archive. This is Activity 4 of the Space Weather Forecast curriculum. (View Less)
This is an activity about the declining strength of Earth's magnetic field. Learners will review a graph of magnetic field intensity and calculate the amount by which the field has changed its intensity in the last century, the rate of change of its... (View More) intensity, and when the field should decrease to zero strength at the current rate of change. Learners will also use evidence from relevant sources to create a conjecture on the effects on Earth of a vanished magnetic field. Access to information sources about Earth's magnetic field strength is needed for this activity. This is Activity 7 in the Exploring Magnetism on Earth teachers guide. (View Less)
Logarithms are very handy when dealing with numbers at different scales but they are also useful helping us average measurements of physical phenomena that have nonlinear behavior. In this example, students learn about cloud albedo and calculating... (View More) cloud optical depth. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.

This is an activity about seasonal variations in day length. Learners will graph the number of daylight hours in each month in cities around the world and compare results. They will also gain an understanding of the meaning of the term equinox... (View More) through review of the graphed data. This is Activity 6 in the Great Explorations in Math and Science (GEMS) guide titled Real Reasons for Seasons: Sun-Earth Connections. The resource guide is available for purchase from the Lawrence Hall of Science. This activity requires use of an overhead projector and colored transparency pens. (View Less)
