GIZMOS Student Exploration

The first Gizmo shows this equation: Fe + 3 CO 2 Fe + 3CO 2 O 3(s) (g)  (s) 2(g) There is a Question to solve under the equation. Here are the features that will help you solve each problem:  Y ou have a set of 16 tiles containing various conversion factors. Any of these tiles can be dragged down and placed on the green bar to solve the problem. The starting tile is already in place. It cannot be moved.  When you place a tile correctly , you will see a red line th...

Vocabulary : Avogadro’s number, chemical equation, chemical formula, chemical reaction, coefficient, combination, combustion, conservation of matter, decomposition, double replacement, molar mass, mole, molecular mass, molecule, product, reactant, single replacement, subscript Prior Knowledge Questions (Do these BEFORE using the Gizmo .) 1. A candle is placed on one pan of a balance, and an equal weight is placed on the other pan. What would happen if you lit up the candle and waited for...

Vocabulary: bacteriophage, capsid, host cell, lyse, lytic cycle, virus Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A computer virus is a program that can copy itself and infect a computer without the permission of the owner. How do you think a computer virus compares to a real virus? A computer virus infects a computer, and a real virus infects an organism. During an infection, both types of viruses make copies of themselves so that more infections can occur. A computer vi...

Vocabulary: allele, genotype, phenotype, probability, Punnett square [Note to teachers and students: This Gizmo was designed as a follow-up to the Mouse Genetics (One Trait) Gizmo™. We recommend doing that activity before trying this one.] Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A single coin is flipped four times. What do you think is the most likely outcome? A. Four heads B. Three heads, one tail C. Two heads, two tails G. H. D. One head, three tails E. Four...

Vocabulary: coefficient, combustion, compound, decomposition, double replacement, element, molecule, product, reactant, single replacement, subscript, synthesis Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The scouts are making s’mores out of toasted marshmallows, chocolate, and graham crackers. 1. What is wrong with the image below? ___________________________________________ 2. Assuming a s’more requires two graham crackers, one marshmallow, and one piece of chocolate...

[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...

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...
