Learners will study the essential components and variables of an ion propulsion system. Activities include an on-line ion propulsion engine simulation and design. Included are changes in energy and fuel consumption as a result of variable changes... (View More) (dependent/independent variable relationships). This is activity 5 of 5 in Structure and Properties of Matter: Ion Propulsion. (View Less)
Learners will construct a simple device to measure how effective different materials are for protecting against sunlight, explain how heat relates to the motion of atoms and molecules, describe how heat can be transmitted from one place to another,... (View More) explain how sunlight arriving on Earth interacts with matter, and describe how MESSENGER is protected by a simple sunshade in the hot Mercurian environment. Materials required to do this activity include several commonly-found items (e.g., coffee cans, ice cubes, tape, ruler, calculators, stopwatch, and scale). This is lesson 3 of 4 at the Grade 9-12 range of "Staying Cool." (View Less)
Learners will consider the essential question, "How much energy does sunlight provide to the Earth and what is its role in the Earth’s energy resources?" Activities include building a device to measure the solar constant - the amount of energy in... (View More) sunlight - calculating the amount of energy arriving at the Earth from the Sun, and describing the differences in solar radiation at Mercury compared to Earth. This is activity 1 of 4 in the module, Staying Cool. Note: the student guide starts on p. 21 of the PDF. (View Less)
