Please follow all written directions when you do these home learning questions!
Students will be able to:
use information from texts, supplementary texts, inquiry activities and classroom discussions to
-identify, compare, and contrast temperature, heat and thermal energy.
-design an experiment to model conduction, convection, and radiation.
The do now was to draw pictures that represent conduction, convection/and radiation.
Students received home learning 3, which can be found at the top of this blog. Be sure to place both on the same sheet of properly headed loose leaf paper. For the first sheet, write true if the statement as written is true. If the statement is false, look at the underlined word. Write the word on your paper that would make the statement true. For the second sheet, write only the letter answer. Remember, your home learning should be on loose leaf paper, written in blue or black ink or pencil.
Students saw heat transfer in action as they watched a "dancing penny" demonstration.
Groups completed their presentations on condensation, convection, and radiation.
Conduction is the transfer of thermal energy through a material by atoms in the material bumping into each other. When you put a cold spoon into a warm cup of tea, the part of the spoon in the hot tea becomes warmer. The atoms and molecules move
faster. These particles hit other slower-moving particles in the spoon. Thermal energy transfers from the faster-moving particles to the slower-moving particles farther up the spoon’s handle.
Convection transfers thermal energy when particles move between objects or areas that have different temperatures. Convection is most common in liquids and gases. As temperature increases, particles move faster and spread farther apart. So the density of the material decreases. The warmer, less dense material rises and the colder, denser material sinks. An example of convection can be found when you look at the flow of air in a two story house. The hot, less dense air rises to the top floor, while the cooler, more dense air can be found on the first floor.
Radiation is the transfer of thermal energy by waves. When waves hit an object, the object absorbs their energy and its temperature rises. Earth gets energy from the Sun through radiation. A microwave oven uses microwave radiation to transfer energy to the food.
Students will paste in all handouts and home learnings at the next class meeting, as well as write their three quality questions and lesson summary.
