Analyzing Investigations PS 9

What question is this investigation designed to answer? How does the surface the car rolls down affect the distance it travels? How does the mass of the car affect how far the car rolls? How does the height of the ramp affect the distance the car travels? How does the distance the car travels affect the height of the ramp? The jars are each filled with an equal amount of water that is 92°C. Students observe and record the water temperature in each jar after 10 minutes.What question is this investigation designed to answer? Which material produces the most thermal energy? How does the length of the thermometer affect thermal energy production? How does the size of the jar affect the thermal conductivity of glass? Which material is the best insulator of thermal energy? Amy is conducting an investigation using caramel candy, paper plates, and a stopwatch. She places a piece of the caramel candy on each of three plates, then she puts the plates in different locations around her school. Amy will record the time it takes for each piece of caramel candy to change state and other observations in the table.Which question is Amy most likely trying to answer with her investigation? In which location does the caramel candy change state the fastest? What causes the caramel candy to keep its shape? Why does caramel candy change state? At what temperature does the caramel candy melt? Alan is doing an investigation. He placed equal amounts of four different soils into identical funnels. Next, he poured equal amounts of water through each sample of soil. The water that passes through each sample is collected in a graduated cylinder. Identify the constants, independent and dependent variables. Independent Variable (what did Alan change) the type of soil Dependent Variable (what was measured) the volume of water passing through the soil Constants (what was kept the same) the funnels ring stands graduated cylinders amount of soil amount of water poured through the funnels Alessandro is performing an investigation to measure how much liquid water is produced from a 10 L sample of snow. What must occur in order for Alessandro to perform this investigation? the samples of snow must be kept in a freezer the temperature of a sample must change the investigation must be performed outside the physical state of the sample must remain the same Label each image with the type of energy that is PRODUCED. sound light sound light sound light sound
