Why do we need to eat food? Food provides us with over 40 substances that it cannot product on its own, therefore we must eat food to get those 40 substa...

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary : absolute zero, controlled experiment, diffusion, dynamic equilibrium, Kelvin scale, kinetic energy Prior Knowledge Question (Do this BEFORE using the Gizmo .) Have you ever smelled microwave popcorn? The oddly enticing scent can fill a whole house. How do you think the smell of popcorn spreads through the air? Gizmo Warm-up Smells are carried by tiny par...

Student Exploration: Coastal Winds and Clouds Vocabulary: condensation, convection, convection current, land breeze, sea breeze Condensation: change from a gas to a liquid Convection: Transfer of heat through movement of a fluid. Convection Current: the circular motion of a fluid (such as air) in which hot material rises while cold material sinks. Land breeze: A wind that blows from the land to the sea. Sea breeze: A wind that blows from the sea to the land. Prior Knowledge Questions (Do...

Student Exploration: Chicken Genetics Vocabulary: allele, codominance, dominant, genotype, heterozygous, homozygous, phenotype, probability, Punnett square, recessive, trial Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. The image shows a flower that was produced by crossing a pure red flower with a pure white flower. Which do you think is the dominant petal color: red or white? Explain. _____________________________________________ ______________________________________...

Student Exploration: Calorimetry Lab Vocabulary : calorie, calorimeter, joule, specific heat capacity Prior Knowledge Questions (Do these BEFORE using the Gizmo .) 1. The La tin word calor means “hea t,” and m eter comes from the Greek word meaning “to measure.” What do you think a calorimeter does? Measures heat. 2. Where have you heard the word calorie before? What do you think a calorie is? With food, the amount of energy it takes to heat up one ml of water. Gizmo Warm-up A ca...

Student Exploration: Building Pangaea Vocabulary: continental drift, fossil, glacier, ice age, landmass, Pangaea, supercontinent Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Antarctica is a frozen land, so cold and icy that no trees can grow there. Yet scientists have discovered fossils (remains preserved in rock) of ancient trees in Antarctica. What do you think this means? ________________________________________________ ________________________________________________...

Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. 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...

Student Exploration: Ray Tracing (Lenses) Vocabulary: concave lens, convex lens, focal point, image, magnification, real image, refraction, virtual image Prior Knowledge Questions (Do these BEFORE using the Gizmo.) Agnes is trapped on a desert island with nothing but a magnifying glass. She wants to use the glass to focus sunlight and start a fire. She holds the glass above some dry grass as shown at right. 1. On the diagram, draw the path the Sun rays will likely take from the magnifyin...
