In this laboratory activity, students will read and plot stars on the HR Diagram. They will color the various parts of it the appropriate colors to relate them to the temperatures. The analysis questions lead students to discover the relative sizes of stars, explore the different star groups, and see where our sun fits into the picture. Note: Parts of the lab refer to the ESRT. This is New York State's Earth Science Reference Tables. Even if you don't teach in New York State, they are a fan

Just like in the many disaster movies, this laboratory activity will allow students to investigate the effects of an asteroid hitting the earth. Students will drop plastic beads onto a tray of sand, causing impact craters from two different heights. They will measure the widths and depths of these craters, then answer questions that discuss their findings and relate it to the solar system, historical events, and possible real-life effects.

In this laboratory activity, students will use foam spheres and a lamp to recreate the Earth's moon's phases. They will then draw a diagram depicting/summarizing their results. The analysis questions lead students to think about the Earth-Moon-Sun system from various perspectives, including at precise times (eclipses), and relate this back to cyclic changes. All images are created as shapes in MS Word, so their quality does not degrade when printed.

In this worksheet, students review some galaxy types, how scientists determine temperature, composition, distance, & speed from starlight, the name & structure of our galaxy, the definition of a light year, and three pieces of evidence for the Big Bang.
