Gizmos student exploration Study guides, Class notes & Summaries

[Note to teachers and students: This Gizmo was designed as a follow-up to the Nuclear Decay Gizmo. We recommend doing that activity before trying this one. Vocabulary: chain reaction, CNO cycle, catalyst, deuterium, electron volt, fission, fusion, isotope, nuclear reaction, positron, positron emission, proton-proton chain Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The chart to the right gives the isotope name, element name, number of protons, and number of neutrons of ...

Vocabulary: antinode, compression, displacement, frequency, interference, longitudinal wave, medium, node, rarefaction, standing wave Prior Knowledge Question (Do this BEFORE using the Gizmo.) In many science fiction movies, an evil alien spaceship explodes with an enormous KABOOM!! Suppose you were floating in space at a safe distance from a large explosion such as the supernova at left. Do you think you would you hear anything? Explain. I don’t think so, I think the sound does...

Prior Knowledge Questions (Do these BEFORE using the Gizmo.) In many science fiction movies, an evil alien spaceship explodes with an enormous KABOOM!! Suppose you were floating in space at a safe distance from a large explosion such as the supernova at left. Do you think you would you hear anything? Explain. I don’t think so, I think the sound doesn’t have anything to vibrate to make the noise in space.

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: acid, base, catalyst, chemical change, coefficient, conservation of matter, decomposition, dissolve, double replacement, endothermic, exothermic, indicator, ion, physical change, product, reactant, single replacement, subscript, synthesis Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A student mixes baking soda and vinegar in a glass. The...

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: dipole, dipole-dipole force, dipole-induced dipole force, electronegativity, intermolecular force, ionic bond, London dispersion force, molecule, nonpolar, nonpolar covalent bond, partial charges, polar, polar covalent bond, valence electron Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A big bully is having a tug-of-war with a small chil...

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: density, mass, matter, volume Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. List three objects that you think would sink in water, and three objects you think would float. Sink: An egg, a penny, and a rock. Float: A ping pong ball, an air-filled balloon, a boat 2. Why do you think some things float and some things sink? Some things floa...

[Note to teachers and students: This lesson was designed as a follow-up to the Weathering and River Erosion lessons. We recommend doing those activities before trying this one.] Vocabulary: climate, erosion, precipitation, sandstone, shale, vegetation, valley, weathering Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Erosion is the removal and movement of soil, rocks, and other materials from one place to another on Earth’s surface. What are some forces that might caus...

Vocabulary: calorie, calorimeter, joule, specific heat capacity Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. The Latin word calor means “heat,” and meter comes from the Greek word meaning “to measure.” What do you think a calorimeter does? to measure heat 2. Where have you heard the word calorie before? What do you think a calorie is? _when looking at the nutritional facts on the back of a_food container

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: effort, load, mechanical advantage, pulley, pulley system Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Suppose you had to haul a heavy bucket of water from a deep well. Which way do you think would be easiest for lifting the bucket? Highlight your answer. a. One person lifting the bucket. b. Two people lifting the bucket. c. Fo...
