GIZMOS STUDENT EXPLORATION THE BIG BANG THEORY MATHS CALCULATION WITH REFERENCING QUESTIONS AND ANSWERS EXAM The distance between Earth and Mars is 225 million km. When converted using the conversion factor 1 AU = 1.5 × 108 km, the distance between the planets is [0.2 AU/1.5 AU/2.0 AU]. The astronomical unit (AU) is [shorter than/longer than/the same as] a lightyear. - 1.5 AU SHORTER THAN Drag each tile to the correct location. A scientist is studying the light emitted by several celes...

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: component, dot product, magnitude, resultant, scalar, unit vector notation, vector Prior Knowledge Question (Do this BEFORE using the Gizmo.) An airplane is traveling north at 300 km/h. Suddenly, it is hit by a strong crosswind blowing 150 km/h from west to east. Draw an arrow on the diagram showing the direction you think the plane will most lik...

Vocabulary: angle of incidence, angle of refraction, frequency, index of refraction, medium, refraction, Snell’s law, total internal reflection, wave front, wavelength, wave speed Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Two runners ran side by side, each holding one end of a horizontal pole. 1. What would most likely happen if one of the runners began jogging in knee-deep water? __________________he would probably slow _____________________________________________...

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: attract, bar magnet, ferromagnetic, magnetize, north pole, repel, south pole Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. What happens when you place two magnets close together? They attract or repel. 2. What objects do magnets stick to? Make a list. Metal, iron, nickel 3. What do these objects have in common? They’re found on ea...

Vocabulary: angle of incidence, angle of refraction, frequency, index of refraction, medium, refraction, Snell’s law, total internal reflection, wave front, wavelength, wave speed Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Two runners ran side by side, each holding one end of a horizontal pole. 1. What would most likely happen if one of the runners began jogging in knee-deep water? The jogger who was running in the water probably slow down. How would this affect the...

Vocabulary: artificial selection, breed, chromosome, evolution, fitness, genotype, mutation, natural selection, phenotype [Note to teachers and students: This Gizmo was designed as a follow-up to the Evolution: Mutation and Selection Gizmo. We recommend doing that activity before trying this one.] Prior Knowledge Question (Do this BEFORE using the Gizmo.)

Vocabulary: Avogadro’s number, balanced equation, cancel, coefficient, conversion factor, dimensional analysis, molar mass, mole, molecular mass, stoichiometry Activity A: Moles Get the Gizmo ready: ● Check that the equation is still: Fe2O3 + 3CO 2Fe + 3CO2 ● If not, click New equation until it reappears. Question: How do scientists find the molecular mass and molar mass of a substance? 1. Calculate: The molecular mass of a molecule is the sum of the masses of each atom in the mo...

Vocabulary: ATP, bacteria, carbon dioxide (CO2), cell, cellular respiration, compound light microscope, eukaryote, multicellular, muscle cell, neuron, organelle, photosynthesis, prokaryote, protist, red blood cell, root hair cell, tissue, unicellular, white blood cell Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. How do you know if something is alive? Describe some of the characteristics of living things. Answer: It is alive if it is composed of cells because it is the fun...
