2. Specific heat capacity can be described as a substance’s resistance to temperature changes. Which substance has a greater specific heat capacity, copper or water? Explain.

Student Exploration: Calorimetry Lab Vocabulary :  calorie, calorimeter, joule, specific heat capacity Prior Knowledge Questions  (Do these BEFORE using the Gizmo .) The Latin word  calor  means “heat,” and  meter  comes from the Greek word meaning “to measure.” What do you think a  calorimeter  does? 2.Where have you heard the word calorie before? What do you think a calorie is?  Gizmo Warm-up A calorimeter is an insulated container filled with a liquid, usually water. When a hot object is placed in the calorimeter, heat energy is transferred from the object to the water and the water heats up. Calorimeters can be used to find a substance’s  specific heat capacity . You will use the  Calorimetry Lab  Gizmo™ to determine the specific heat capacities of various substances. 1. On the SIMULATION pane, select  Copper . Use the slider to set its  Mass  to 200 g. Set the  Water mass  to 200 g. Check that the  Water temp  is set to 30.0 °C and the copper’s  Temp  is 90 °C. S

Question: How can you predict angular velocity based on the total energy of the turntable and how its mass is distributed?

Student Exploration: Moment of Inertia Vocabulary :  angular velocity, linear velocity, moment of inertia, rotational kinetic energy, translational kinetic energy Prior Knowledge Questions  (Do these BEFORE using the Gizmo.) At the finale of her routine, a figure skater starts to spin slowly in the middle of the ice rink, her arms and legs artfully outstretched. What will happen as she stands up straight and pulls her arms in? Why do you think this will happen? Gizmo Warm-up The  Moment of Inertia  Gizmo™ allows you to explore the factors that affect how quickly objects spin. The Gizmo shows a weightless turntable with several pegs. You can place the purple 1-kg masses on any of the pegs. When the Gizmo opens, there is a single 1-kg mass located 5 m from the center. Click  Play  ( ). What happens? The speed of rotation is described by  angular velocity  ( ω ), which is measured in radians per second. There are 2 π  radians (6.28 radians) in a circle. What is the c

1. DNA is composed of the bases adenine (A), cytosine (C), guanine (G), and thymine (T). RNA is composed of adenine, cytosine, guanine, and uracil (U). Look at the SIMULATION pane.

Student Exploration: RNA and Protein Synthesis Vocabulary : amino acid, anticodon, codon, gene, messenger RNA, nucleotide, ribosome, RNA, RNA polymerase, transcription, transfer RNA, translation Prior Knowledge Questions (Do these BEFORE using the Gizmo .) 1. Suppose you want to design and build a house. How would you communicate your design plans with the construction crew that would work on the house? 2. Cells build large, complicated molecules, such as proteins. What do you think cells use as their “design plans” for proteins Gizmo Warm-up Just as a construction crew uses blueprints to build a house, a cell uses DNA as plans for building proteins. In addition to DNA, another nucleic acid, called RNA , is involved in making proteins. In the RNA and Protein Synthesis Gizmo™, you will use both DNA and RNA to construct a protein out of amino acids . 1. DNA is composed of the bases adenine (A), cytosine (C), guanine (G), and thymine (T). RNA is composed of adenine, cytosine
