Learners model how Earth's tilt creates the seasons. They use their bodies to review the Earth's daily motions before investigating the reason for Earth's seasons in this kinesthetic exploration. The motion of the Earth about its axis (rotation) and... (View More) in orbit around the Sun (revolution) is related to the appearance of the sky over the course of the day and year. Next they model that if the Earth's tilt was not stabilized by Moon, Earth's axis would slowly wobble between straight up (0° tilt) to nearly on its side (80° tilt). The resulting seasonal extremes would be unfavorable for life. Note that this activity is appropriate for children who are able to explore the geometry of Sun-Earth-Moon relationships in three dimensions. This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries. (View Less)

Learners will record detailed observations of a simulated surface and core sample of Mars, analyze a simulated surface and core sample of Mars, compare and contrast an unknown foreign object with the surface and interior of Mars, and learn... (View More) preliminary facts about Mars, its surface, and its place in the Solar System. The lesson uses the 5E instructional model and includes: TEKS Details (Texas Standards alignment), Essential Question, Science Notebook, Vocabulary Definitions for Students, Vocabulary Definitions for Teachers, three Vocabulary Cards, and a Mini-Lesson. This is lesson 2 of the Mars Rover Celebration Unit, a six week long curriculum. (View Less)

Learners will brainstorm possible solutions for the scientific question generated in lesson 5 of this unit and determine the reasonableness of solutions. The lesson uses the 5E instructional model and includes: TEKS Details (Texas Standards... (View More) alignment), Essential Question, Science Notebook, Vocabulary Definitions for Students, Vocabulary Definitions for Teachers, two Vocabulary Cards, and a concept map supplement. This is lesson 6 of the Mars Rover Celebration Unit, a six week long curriculum. (View Less)

Learners will use critical thinking and a collaborative approach to pose questions related to the study of Mars and evaluate the quality of their questions. They will explore remote-sensing data collected by a camera orbiting Mars - the Thermal... (View More) Emission Imaging System (THEMIS) and develop a team science question. Students will practice critical thinking skills, use a collaborative approach to this first critical step of the scientific process. Exploring the images of the surface of Mars in Visible (VIS) images, students will come up with a topic of study, their team science question and hypotheses. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary. (View Less)

This is an activity about the Signal-to-Noise Ratio. Learners will engage with a hands-on activity and an online interactive to understand the terms signal and noise as they relate to spacecraft communication; quantify noise using a given dataset;... (View More) and calculate the signal-to-noise ratio. The activity also includes a pencil-and-paper component that addresses relevant topics, such as proportions and ratios. Includes teacher background information, student data sheets, answer guide, extensions and adaptions. (View Less)

In this activity, learners will explore the question, What is the chance that we are the only life in the universe? They determine what we need to know to predict the chances of extraterrestrial life. They then make estimates of the number of worlds... (View More) in the Milky Way galaxy that have life using the Drake equation. Includes background reading for teachers, student pages, reflection questions, and blackline masters. This is activity 5 of 5 in "Astrobiology in your Classroom: Life on Earth..and Elsewhere?" and builds on the previous activities. (View Less)
