Students will be able to distinguish between materials that are good conductors and those that are good insulators. Students will know that when heat is applied to objects, molecules begin to move more rapidly. Students will interact with solar energy. Students will learn how static electricity is created. Students will compare materials to see which will repel a balloon and which would attract a balloon. All items in bold are available as supporting documents attached to this lesson plan. Key Vocabulary NC Essential Standards For Science energy conductor insulator transfer thermal energy potential energy kinetic energy temperature static electricity friction atoms electrons protons neutrons molecule charge attract repel solar Essential Standards: 3.P.3 Recognize how energy can be transferred from one object to another Clarifying Objective: 3.P.3.1 Recognize that energy can be transferred from one object to another by rubbing them against each other. 3.P.3.2 Recognize that energy can be transferred from a warmer object to a cooler one by contact or at a distance and the cooler object gets warmer. Common Core Standards 3.NTBT.2 Fluently add and subtract within 1000 using For Mathematics strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. 3.MD.3 Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets. 3.MD.4 Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units whole numbers, halves, or quarters. Common Core Standards 3.RL.1 Ask and answer questions to demonstrate for ELA & Literacy understanding of a text, referring explicitly to the text as the basis for the answers. 3.RL.3 Describe characters in a story (e.g., their traits, motivations, or feelings) and explain how their actions contribute to the sequence of events. 3.RI.7 Use information gained from illustrations (e.g.,maps, photographs) and the words in a text to demonstrate understanding of the text (e.g., where, when, why, and how key events occur). 3.RI.9 Compare and contrast the most important points and key details presented in two texts on the same topic. 3.W.1 Write opinion pieces on topics or texts, supporting a point of view with reasons. a.!

Lesson 2: EQ: Does greater potential energy convert into greater kinetic energy? Read The Little Engine that Could by Wally Piper aloud to the class. Discuss simple machines. Lesson 25 from Elementary Science with Vernier: (25 Drive with Energy) Students will work in small groups to conduct an experiment using toy cars. The students will pull the cars back to predetermined distances and release the car. The students will then measure how far the cars travelled using the motion probe. Students will record this information in their science notebooks. Students will create a bar graph to display the information from the experiment. Exit Slip: The students will demonstrate their knowledge of potential or kinetic energy on the provided exit slip. Activities/Procedures •Essential Question •Explore/Engage •Explain •Elaborate (Inquiry) •Evaluate Lesson 3: EQ: What role does friction play in static electricity? Teacher will demonstrate how friction assists in static electricity. Students will make predictions about what would happen if animal fur was rubbed 1 time versus 100 times against a metal rod and placed on the Van de Graff generator. The teacher will introduce students to static electricity by asking the students, “How can you tell if static electricity is around you?” The teacher will encourage students to describe any experiences that they have had with static electricity. Record answers and discuss. Teacher will explain how static electricity is created showing the students an atom. Teacher will explain three smaller particles of the atom: electrons, protons, and neutrons. Teacher can use the following (Electricity info for teachers) for background information. Teacher will demonstrate attraction and repulsion through a demonstration with magnets, Teacher will also show how a balloon can pick up confetti when charged (more electrons than protons). Static electricity is a build up of electrons. Students will work in small groups to complete an inquiry lesson on static electricity. Activity: Stuck on You: Static Electricity Exit Slip: The students will demonstrate knowledge of static electricity on the provided exit slip. Activities/Procedures •Essential Question •Explore/Engage •Explain •Elaborate (Inquiry) •Evaluate Lesson 4: EQ: What are insulators and conductors? Teacher will have set up in the classroom three glasses of water. One will be hot, one room temperature, and one will have ice in it. A wire coat hanger will be placed in each glass. Upon entering students will make observations in their lab notebooks using their five senses. Teacher will begin the lesson by asking if the students have heard of the words conductor or insulator? Teacher will have students give examples of each. Teacher will build background knowledge by showing the Keynote presentation (Heat Conducting Materials) to the class. Students will be completing a study guide outline as the teacher is building background knowledge. (Lesson Outline) Invite two students come to front of the class and give each of them an ice cube in a sealable bag. Have the students hold the ice cube and ask, “What is happening?” Clarify that the ice did not bring cold to the hand, but the heat from the hands moved to the ice cube, until they finally became the same temperature. Students will show what they know about insulators and conductors on the provided exit slip. Activities/Procedures •Essential Question •Explore/Engage •Explain •Elaborate (Inquiry) •Evaluate Lesson 5: EQ: Which material would be best in keeping objects cold? Why? Students will participate in an ActivInspire lesson (Keeping Warm - Thermal Energy.flp) Design a Refrigerator Tell the students that today they are going to design a refrigerator. The goal is to keep their ice cube from melting. Students will be designing 2 refrigerators, using different materials. They may use paper towels, wax paper, foil, plastic bags, newspaper, styrofoam, towels, or cotton. The students will assemble their refrigerators. After the refrigerators are assembled, students will place 2 ice cubes inside each. Go outside. Instruct students to take an initial reading of the temperature in Fahrenheit using the Vernier LabQuest. They will record this data in their lab notebooks. Students will use a stopwatch or a timer to record the temperature every 2 minutes for 10 minutes. Students will record the final temperature at the end of 10 minutes in their lab notebooks. Students will then make a bar graph to display data. Which worked best? Why? Students will use information to come up with a design for a cup that would keep drinks cold on the beach or in the desert.

Teacher will build background knowledge of thermal heat and heat transfer by showing the ActivInspire flip chart (Keeping Warm - Thermal Energy.flp) The team mission is to design and build a solar box cooker, and test it out to see if it works well enough to cook a marshmallow! The teacher will tell the students that they must meet the following specifications: 1. Your solar oven may be no larger than 16 inches by 16 inches. 2. You may use any available materials to line the bottom and inside of box. 3. Your food may not touch the bottom of the oven directly. You must design a way to best cook the marshmallow off of the bottom surface. 4. After you complete your solar oven, you need to insert a thermometer inside. Set the Vernier LabQuest to record the temperature every 30 seconds for 10 minutes. Record this information on the data table provided.
