This unit investigates asteroids, comets, and meteoroids, focusing on Vesta, a prominent asteroid in the asteroid belt. The unit of eleven lessons culminates in having students use engineering practices to design, build, and test devices that will... (View More) land on Vesta, collect and separate natural resources found there, and deliver a payload to a target. Teachers and students are also introduced to the Asteroid Mappers-Vesta Edition citizen science project that is part of the CosmoQuest online community. Lessons include background information for educators, reviews and assessments, and links to supplemental videos and websites. Next Generation Science Standards (NGSS) and Common Core Standards are listed. (View Less)

This is a lesson about how to answer a scientific or engineering question. Learners will refine the scientific question they generated in Lesson 5 so that it can be answered by data and/or modeling, brainstorm possible solutions for the scientific... (View More) question chosen, determine reasonableness of solutions, use concept maps to enhance meaningful learning. 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, 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)

This is a lesson about the field of astrobiology, the study of life in the universe, and ice as a preservative for evidence of life. Learners will consider the relationship between ice and life as they investigate the conditions required for life to... (View More) exist and sustain itself. They will study the impact of freezing on microbes and life processes and will learn about extremophiles, organisms that live in extreme conditions. Activities include small group miming, speaking, drawing, and/or writing. This is lesson 8 of 12 in the unit, Exploring Ice in the Solar System. (View Less)

Learners will design and conduct experiments to answer the question, "how does distance and inclination affect the amount of heat received from a heat source?" They will measure heat change as a function of distance or viewing angle. From that... (View More) experiment, they will identify how the MESSENGER mission to Mercury takes advantage of these passive cooling methods to keep the spacecraft comfortable in a high-temperature environment. This is lesson 3 from MESSENGER Education Module: Staying Cool. Note: the student guide starts on p. 24 of the PDF. (View Less)
