Gizmos Student Exploration- DNA Profiling 2025 ACTUAL EXAM (TESTING REAL EXAM QUESTIONS)AND VERIFIED ANSWERS ( 100% ACCURATE) GET IT RIGHT!!

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...

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...

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.
