In this lesson about cosmic rays, students will describe why cosmic rays are dangerous to astronauts. Includes information about student preconceptions. This is activity 3 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation (CRaTER)."
This is a lesson about using analogues to look for life on other planets. Learners will use the results of previous lessons to write a scientific proposal to explore another planet or moon in our solar system for signs of life. This proposal should... (View More) predict the types of energy and nutrients available to sustain life and describe equipment and instruments necessary for exploration and characterization of the target environment. This is activity 4, the capstone activity, in Exploring Deep-Subsurface Life. Earth Analogues for Possible Life on Mars: Lessons and Activities. (View Less)
This is an activity about the discovery of water ice on Mars and involves the use of remote sensing data. Through a Socratic dialogue, learners will analyze three different kinds of data collected by Mars spacecraft to investigate the composition... (View More) and distribution of ices at the high latitude regions of Mars. An extension activity is available in which students use an online simulation illustrating how gamma rays can be used to determine the composition of the Martian surface. This is activity 2 of 5 in Buried Water Ice on Mars. (View Less)
This is an activity about the correlation between annual precipitation and plant productivity in different Earth biomes. Learners consider water evaporation, solubility and abundance relative to life on Earth and relative to finding evidence for... (View More) life on Mars. An extension activity investigates the connection between liquid water, biomes and plant productivity on Earth. This is the 1st of 5 activities in Buried Water Ice on Mars. (View Less)
Working in pairs, students will create experimental conditions in terrariums in order to study what plants need to live. Variables to study include the presence or absence of soil, water, and sunlight. Students will record the growth of radish... (View More) plants as well as observations of "the water cycle" in their terrariums. At the conclusion of their experiments, students will share their results with the class and discuss how water, Earth materials, and air are all necessary to support living things. The activities use commonly-available or inexpensive materials (e.g., chart paper, clear soda bottles, potting soil, radish seeds, paper towels, water, tape, foil, and index cards). This is the first of three sets of learning activities that are companion activities to the Elementary GLOBE children's book, All About Earth: Our World on Stage. Includes a teacher implementation guide. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)
In this activity, student teams design small-scale physical models of hot and cold planets, (Venus and Mars), and learn that small scale models allow researchers to determine how much larger systems function. There is both a team challenge and... (View More) competition built into this activity. Experimental findings are then used to support a discussion of human outposts on Mars. The resource includes an experimental design guide for students as well as a handout outlining a method for the design of controlled experiments, and student data sheets. Student questions and an essay assignment are provided as classroom assessments. This is Activity A in the second module, titled "Modeling hot and cold planets," of the resource, "Earth Climate Course: What Determines a Planet's Climate?" The course aims to help students to develop an understanding of our environment as a system of human and natural processes that result in changes that occur over various space and time scales.
