But I think you’re not really even thinking about work/heat/radiation in that paragraph. A stem and leaf plot breaks each value of a quantitative data set into two pieces: a stem, typically for the highest place value, and a leaf for the other place values. Carefully label the pies to correspond with the positions of the objects given. Use pie charts to analyze the energy changes in each situation given. Thanks for playing! I will run through the typical way I introduce the diagram in class in just a minute. • Remember the 4 energy questions in deciding about the energy changes: 1. Composition 3. • Remember the 4 energy questions in deciding about the energy changes: 1. The pie charts illustrate the changes in energy production from five different sources (oil, natural gas, coal, hydroelectric power and nuclear power) for the USA in two different years (1980 and 1990). We could look at ∆Etherm, ∆K, ∆Ug, ∆Us, etc. (Yes.) It’s the first time they are thinking about the different flavors of energy at all. Use pie charts to analyze the energy changes in each situation given. Not really necesary, but helpful to making the transition to bar charts. • Carefully label the pies to correspond with the positions of the objects given. Thanks for the rundown on pie chart introduction. (A, B,C, etc.) • Designate your choice of system by explicitly listing the objects included. Let’s do it twice, then. ], Great!

And there’s a lot less erasing (so, a little less frustration). Okay! The first thing we need to do is define what we’re saying is in our system. (Does it hit the ground? Right—there might be some cases where that happens, but not in the situations with simple objects that we’re looking at right now. Is there any interaction that happens between the second and third pie that would cause even more energy to be stored as thermal energy? Telling the story with pie charts can be challenging. Tip: If you’re using a pie chart, try to keep below five categories so that the visuals are clear. There are a lot of labels and details. (Smaller.) That’s a good question. The amount it changes isn’t very much, actually, compared to how much it is already storing before, say, a ball bounces on a table. Energy Pie Charts INSTRUCTIONS: Use pie charts to analyze the energy changes in each situation given. Designate your choice of system with a dotted line. I’ll put my energy diagramming reading pages on the interwebs sometime. ], Remember earlier when we were first talking about thermal energy? It really doesn’t matter what they decide as long as it is consistent and makes sense to them. Another good use for a pie chart would be to compare areas of growth within a business such as turnover, profit and exposure. (I don’t think it’s called that anymore.) [I draw a larger slice of K in the final pie.]. (No, it has to stay ∆Etherm.) We’re finished? Say “hi” to your teacher for me! • Designate your choice of system with a dotted line Choose your system so that the energies involved are internal (within the system). What’s your favorite flavor of energy (not thermal)? The overview contains the key features of the charts. Before doing anything else, list the objects in your system. Aces. Divide the pies in a qualitatively accurate fashion, and label them with the energy storage mechanism involved. • Carefully label the pies to correspond with the positions of the objects given. Less homework, more thinking. • Divide the pies in a qualitatively accurate fashion, and label them with the energy storage mechanism involved. Thank you so much for playing! ), Okay, is there any interaction between the first pie and the second pie that would cause some energy to be stored as thermal? Do you think we should take it out of Ug or out of K? The air.) They are ready to add in some details. Make beautiful data visualizations with Canva's graph maker. Use pie charts to analyze the energy changes in each situation given. Use pie charts to analyze the energy changes in each situation given. •Carefully label the pies to correspond with the positions of the objects given. Now let’s look at pie charts specifically. The diagram will only make sense in the context of your chosen system, so you need to be explicit about that. Does the amount of energy stored as kinetic energy increase, decrease, or stay the same? • Designate your choice of system both with a dotted line and with words.
