In a class demonstration, the teacher places different pill types ("chalk" pill, gel pill, and gel tablet) into separate glass beakers of vinegar, representing human stomach acid. After 20-30 minutes, the pills dissolve. Students observe which dissolve the fastest, and discuss the remnants of the various pills. What they learn contributes to their ongoing objective to answer the challenge question presented in lesson 1 of this unit.

Students use the free computer game Pingus to learn how engineers, specifically environmental engineers, use their technical writing skills to give instructions and follow the instructions of others. Students learn to write instructions to express their ideas in clear, organized ways using descriptive, un-ambiguous sentences, as an example of one type of technical writing that important for engineers. The students write instructions enumerating how to beat a game level, which represents surveying that level for environmental problems. As a test of their instructions, students review each others' instructions and offer suggestions for improvement, and then revise their instructions to make them better. Students also see some examples of environmental problems.

PHYSICAL SCIENCE Erlen needs your help to unlock his buried treasure! Using your knowledge of magnetism, help Erlen recover three keys buried in the ground to open his treasure chest.
ABOUT THE SCIENCE Did you know that magnets aren’t just found on your fridge? One natural mineral that acts as a magnet is magnetite, which is also known as lodestone. When suspended and dangled from a string, pieces of lodestone created the first magnetic compass. The stone would turn on the string and point to magnetic north. Magnetic objects can not resist the pull of a magnet because they have metals that contain iron, nickel or cobalt. These objects are pulled or rejected by magnets because of an invisible magnetic force produced by a magnet, which causes magnetic materials to either be attracted or repelled. The magnetic field that surrounds magnets is created by the North and South poles on magnets. Like the North and South poles on Earth, these are the opposite ends on a magnet, which will either attract opposite poles (i.e. North and South) or repel like poles (e.g. North and North). A compass is not the only use for a magnet in everyday life. Your refrigerator door uses a magnet to make sure the door closes and they are uses for recycling drink bottles to separate out the caps from the containers. On a larger scale, they are used in Japan on the Maglev (magnetic levitation) trains on the tracks where the train floats. These super conductive magnets are working on the repulsion of the magnets to keep the trains up from the rails, free of friction.

This is an activity about the way distance, albedo, and atmosphere affect …
This is an activity about the way distance, albedo, and atmosphere affect the temperature of a planet. Learners will create a planet using a computer game and change features of the planet to increase or decrease the planet's temperature. They will then discuss their results in terms of greenhouse strength and the presence of liquid water. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System.
This is an activity about the atmospheric conditions (greenhouse strength, atmospheric thickness) …
This is an activity about the atmospheric conditions (greenhouse strength, atmospheric thickness) Mars needs to maintain surface water. Learners will use a computer interactive to learn about Mars past and present before exploring the pressure and greenhouse strength needed for Mars to have a watery surface as it had in the past. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System.
This is an activity about how much atmospheric pressure is needed on …
This is an activity about how much atmospheric pressure is needed on Mars to maintain surface water and why it does not have surface water today. Learners will use a computer interactive to learn about Mars past and present before exploring the pressure and greenhouse strength needed for Mars to have a watery surface as it had in the past. This lesson is part of Project Spectra, a science and engineering education program focusing on how light is used to explore the Solar System.

Learners and their families are encouraged to go outside on a clear evening and view the sky to see the planets for themselves. Using sky charts and other resources, and possibly in partnership with a local astronomical society, children navigate the night sky and view planets with the naked eye and binoculars or telescopes. This activity is part of Explore! Jupiter's Family Secrets, a series designed to engage children in space and planetary science in libraries and informal learning environments.
