In this lesson, students consider observations and inferences to determine the support for each of two theories on the origin of the universe: Steady State and Big Bang. Working with partners, students draw from a set of Evidence cards (master is... (View More)

In this lesson, students create a fictional narrative on the beginning of time. They use their scientific knowledge of the Big Bang Theory and go back into time to when it occurred so they can make observations about it. Students can select from... (View More)

In this lesson, students explore the cosmic microwave background to understand why it permeates the universe and why it peaks as microwave radiation. Students should be able to explain that the origin of the background radiation is the uniform... (View More)

Students utilize two reading strategies that can be used to understand the Cosmic Times materials, as well as other readings that may be challenging to them. The first strategy, called Talking to the Text, is an independent strategy in which the... (View More)

In this lesson, students explore a discrepant event when they design an experiment to measure the rate that ice melts when in pure water versus salt water. It is designed to help students realize that a carefully-designed experiment may yield... (View More)

In this lesson, students create a timeline of world events from 1905 until 2006. Students locate key dates from the Cosmic Times poster series and determine world events that fit into the three story strands of Cosmic Times, as well as, the... (View More)

In this lesson, students measure the size of several galaxies to reproduce a plot of Hubble's Law. The goal of this lesson is to give students the chance to simulate the process that led to the notion that the universe is expanding, provide insight... (View More)

In this activity, learners discover new perspectives on geothermal features, such as geysers, mudpots, hot springs, and hot spring terraces by exploring infrared images. Learners will gain an understanding of infrared light and infrared imaging, as... (View More)

In this laboratory activity, students observe what happens when a fluid of one density is placed in a fluid of a different density. The fluids are salt water and fresh water, cold water and warm water. They generalize their results to describe what... (View More)

Sea floor spreading is demonstrated using a model consisting of two classroom desks and an 8-foot strip of paper. Changes in polarity are indicated using a felt marker. The investigation supports material presented in chapter 3, "What Heats the... (View More)
