Curated OER
When a Ruler is Too Short
Students measure distances using parallax. In this math lesson, students explain how this method helped astronomers with their studies of the solar system. They determine the length of their arm using parallax and compare it with other...
Curated OER
Three D Constellations
Students address a major misconception in astronomy, the understanding of scale. The instructional activity is designed to introduce students to both celestial coordinates and to the first rung on the distance determination ladder,...
Curated OER
Distances to Stars
Students explore the idea of parallax. For this astronomy lesson, students study the distances of stars. They investigate how parallax can be used to determine these distances.
Curated OER
Discovering Planet X
Learners investigate the movements of the planet Pluto. Students participate in a hands-on activity to record data similar to the movements of the planet Pluto. Learners compare their data to that found on a website.
Curated OER
Distance And Parallax
Students will determine distances to nearby stars using parallax. In this Astronomy lesson plan, students will use a web program, trigonometry, and sketches to determine the distance of stars.
Curated OER
Using Parallax to Determine Distances
Students study parallax and what it is used for. For this distance lesson students complete an activity that allows students to get experience using a parallax.
Curated OER
Three D Constellations
Students are introduced to both celestial coordinates and to the first rung on the distance determination ladder. They convert spherical coordinates to Cartesian coordinates to construct a three dimensional model of a constellation...
Curated OER
Looking Back in Time (Alternative Activity)
High schoolers, in groups, devise alternative ways of measuring distances. They view a video and are introduced to the concept of parallax in measuring. They discuss their ideas with the class.
Curated OER
Using Parallax to Determine Distances
Students examine the concept of parallax. They determine a method to calculate the distance of objects from their data, participate in a demonstration, and describe how our eyes use parallax to determine the distance of objects.
