Learners will be introduced to the concepts of error analysis, including standard deviation. They will apply the knowledge of averages (means), standard deviation from the mean, and error analysis to their own classroom distribution of heights. They... (View More)

This lesson provides a way for students to determine the relationship between the distance from a light source and its brightness. Once students discover the relationship, they can begin to understand how astronomers use this knowledge to determine... (View More)

In this activity, learners draw a circle with a single focus, an ellipse with two foci close together, and an ellipse with two foci far apart, and compare the shapes. Learners then measure the Sun in four images each taken in a different season,... (View More)

In this activity about spectroscopy, learners build a spectroscope, learn about graphing spectra, and then identify elements in gas tubes using their spectra. The activity concludes as learners graph the spectra of different materials. Essential... (View More)

In this activity about the Sun's influence on plant growth, learners will create a plant box and observe that a plant will grow towards the Sun, its primary source of energy. By periodically collecting data on the growth of the plant, they can come... (View More)

This is an activity about the motion of the Earth around the Sun. Learners will act out the motions of Earth as it orbits around the Sun over the course of one year, starting with modeling one day, then one year, and finally the months.

In this kinesthetic activity, learners act out the rotation and revolution motions of Earth around the Sun over the course of one year. Learners also physically model the tilt of the Earth and will identify the summer and winter solstice and vernal... (View More)

In this hands-on activity, learners begin by estimating the size of each planet in our Solar System and Pluto and making each out of playdough or a similar material. Then, learners follow specific instructions to divide a mass of playdough into the... (View More)

This is an activity about the relation between day length and temperature. In one team, learners will create and analyze a graph of hours of sunlight versus month of the year for a number of latitudes. In another team, learners will graph... (View More)

This is an activity involving observations of the Sun. Learners use pinhole cameras, solar telescopes, and/or solar viewing glasses to make solar observations, draw what they see, and identify sunspots, if they are present. Then, learners go online... (View More)
