Student Exploration: Carbon Cycle (ANSWER KEY)

DOWNLOAD Student Exploration: Carbon Cycle Vocabulary :  atmosphere, biomass, biosphere, carbon reservoir, carbon sink, fossil fuel, geosphere, greenhouse gas, hydrosphere, lithosphere, photosynthesis Prior Knowledge Questions  (Do these BEFORE using the Gizmo.) In the process of  photosynthesis , plants take in carbon dioxide (CO 2 ) from the atmosphere and water (H 2 O) from the soil. Using the energy of sunlight, plants build molecules of glucose (C 6 H 12 O 6 ) and oxygen (O 2 ). How do plants on Earth affect the amount of carbon in Earth’s atmosphere? Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in Earth’s atmosphere? Gizmo Warm-up The  Carbon Cycle  Gizmo™ allows you to follow the many paths an atom of carbon can take through Earth’s systems. To begin, notice the black carbon atom in the  Atmospheric CO 2   area, highlighted in yellow. The glowing blue areas represent possib...

Student Exploration: Density Experiment: Slice and Dice (ANSWER KEY)

DOWNLOAD Student Exploration: Density Experiment: Slice and Dice Vocabulary :  density, mass, matter, volume Prior Knowledge Questions  (Do these BEFORE using the Gizmo .) What do you think would happen if you threw a block of polystyrene (Styrofoam™) into the water? What would happen if you broke the Styrofoam up into lots of pieces, then threw the pieces into water? . What would happen if you threw a big rock into water? . What would happen if you broke the rock into little pieces, then threw the pieces into water? . Gizmo Warm-up The  Density Experiment: Slice and Dice  Gizmo™ allows you to compare different-sized pieces of the same material. Check that  Polystyrene  is selected. Drag the whole polystyrene piece into the water. Does it sink or float? Click  Reset , and then click  Slice  to cut the polystyrene into pieces. Drag each piece into the water and then back to the block. What happens? . How do you th...

Student Exploration: Half-life (ANSWER KEY)

DOWNLOAD Student Exploration: Half-life Vocabulary :  daughter atom, decay, Geiger counter, half-life, isotope, neutron, radiation, radioactive, radiometric dating Prior Knowledge Questions  (Do these BEFORE using the Gizmo .) Have you ever made microwave popcorn? If so, what do you hear while the popcorn is in the microwave? If you turn the microwave on for two minutes, is the rate of popping always the same, or does it change? Explain.     Gizmo Warm-up Like an unpopped kernel in the microwave, a  radioactive  atom can change at any time. Radioactive atoms change by emitting  radiation  in the form of tiny particles and/or energy. This process, called  decay , causes the radioactive atom to change into a stable  daughter atom . The  Half-life  Gizmo™ allows you to observe and measure the decay of a radioactive substance. Be sure the sound is turned on and click  Play  (). W...
