This is a lesson about making careful observations. Learners will get to know the surface of an unshelled hard-boiled egg and try to draw and sketch the surface features of their egg in sufficient detail so that a person in another group will... (View More)

This is an activity about the planet Mars. Learners will create cratered surface models illustrating different lengths of time. Then, they will compare their models with three different surface images of Mars, placing these images in order from... (View More)

This is an activity about the Earth's revolution as it relates to the zodiac. Learners will role-play, acting as the revolving Earth and Sun, while others will hold signs of the 12 zodiac constellation names to form a circle around the Earth-Sun... (View More)

This is a website that serves as an online textbook to tell the story of William Gilbert, English physicist during the time of Queen Elizabeth I, and the history of the discovery of Earth's magnetism. Learners can read about historical studies of... (View More)

This is a lesson about observation. Learners will look at nine nights of observations of the positions of Jupiter's four largest moons in relation to Jupiter and construct a data graph that allows them to calculate the orbital period of each moon.... (View More)

This is an activity about the position of the Moon and the Sun in the sky. Learners will use styrofoam balls to model the interactions between the Earth, Sun, and phases of the Moon. This is Activity A-5 of Universe at Your Fingertips 2.0: A... (View More)

This is an activity about critical observation skills. Learners will receive an egg to record its features from various vantage points, illustrating their size, shape, and location. They will then try to identify and recognize the surface features... (View More)

This is an activity about the rotation of the Sun. Learners examine images of the Sun taken by the Yohkoh satellite, use a grid overlay to mark the positions of the sunspots, and then calculate the rate at which the spots move to determine the... (View More)

This is an activity about measuring craters using shadows and geometry. Learners will make a model crater and use a light source to make a shadow. When they are familiar with the techniques for estimating depths from shadows, they will apply their... (View More)
