Student Exploration: Natural Selection Vocabulary: biological evolution, camouflage, Industrial Revolution, lichen, morph, natural selection, peppered moth Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The peppered moth (Biston betularia) is a common moth found in Europe, Asia, and North America. It is commonly found in two forms, or morphs: a dark morph and a light, speckled morph. Birds are a frequent predator of the peppered moth. 1. Which morph do you think would be easier...

Part 0: Prior Knowledge Check -------------------------------- 1. On the image at right, the two magnets are the same. Which paper clip would be harder to remove? Magnet B because there is less blocking the magnetic pull As the book thickness increases the ability of the magnet to hold on to and attract paper clips decreases. Name: Student Exploration: Periodic Trends Directions: Follow the instructions to complete your group's section of the simulation. Respond to the questions and promp...

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 three isotopes. 1. What do you notice about the isotope number and the sum of protons and neutrons? 2. The element symbol for uranium-238 is . This means U-238 has a total mass of 238 and contains 92 protons. Write the element symbols for the isotopes in the table: Hydrogen-1 Carbon-12 Uranium-235 Gizmo Warm-up The Nucle...

Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. In the image to the right, note a dozen eggs, a dozen donuts and a dozen roses. How many of each item do you have? 12 2. Would a dozen of each object have the same mass? no 3. Suppose you have a dozen carbon atoms, a dozen gold atoms, and a dozen iron atoms. Even though you have the same number of each, would you expect them all to have the same mass? Explain. No, just because they have the same quantity doesn’t mean they weig...

Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. What do plants need to survive? Plants need space, air, and ideal temperatures . 2. How do plants reproduce? Plants reproduce through asexual for sexual reproduction. In asexual reproduction it's done through the roots stems and even the leaves on the plant itself , but through sexual reproduction there's a Fusion between Bell and female gamuts in the specific plan. Gizmo Warm-up Several common vegetables, including Bok cho...

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 tails F. All are equally likely 2. What do you think are the odds of getting four tails in a row? Explain your answer. A. B. The odds of getting four tails in a row are ½ * ½ * ½ * ½ because every flip has an equal probability of being heads or tails. So with 4 flips you would have a 1/16 chance. ...

1. Cells reproduce by splitting in half, a process called cell division. What do cells need to do between divisions to make sure that they don’t just get smaller and smaller? <A cell must grow > 2. The genetic information of a cell is carried in its DNA (short for deoxyribonucleic acid). What do cells need to do between divisions to make sure that a full set of DNA gets passed on to each daughter cell? <The DNA must be copied so there is a full set of DNA to pass on to each daughter ...

Student Exploration: Boyle’s Law and Charles’s Law Vocabulary: absolute zero, Boyle’s law, Charles’s law, Gay-Lussac’s law, Kelvin scale, pressure Prior Knowledge Question (Do this BEFORE using the Gizmo.) A small helium tank measures about two feet (60 cm) high. Yet it can fill over 50 balloons! How can such a small tank contain enough helium to fill so many balloons? The small container can hold all that helium in the container because the gas in the tank is under a lot of pres...

Student Exploration: Free-Fall Laboratory Vocabulary: acceleration, air resistance, free fall, instantaneous velocity, terminal velocity, velocity, vacuum Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Suppose you dropped a feather and a hammer at the same time. Which object would hit the ground first? I believe the hammer falls faster since it weighs more. 2. Imagine repeating the experiment in an airless tube, or vacuum. Would this change the result? If so, how? The result...
