I sometimes flippantly call this big idea ‘the effect of ratios, powers and logarithms’. 0 The interactions of chemicals pretty much cover the same ground. In general chemistry: The elaboration for the student is more detailed here than for the other big ideas. You should notice that heat or energy is involved in both these examples. This big idea starts with what is one, if not, the most important equation in all of science. <>>>/BBox[0 0 625.44 818.36]/Length 46>>stream It is my belief that the stand alone placement of ‘nuclear chemistry’, usually in one of the final chapters of most textbooks, is inappropriate.

But I do think it might serve as good starting point to work from to get the notion of big ideas into chemistry. In other words, these ideas had to have ‘legs’. For instance in the example of the flooding, if the humans behaved like substances not all would leave when the flooding started; in fact some from high ground would move into the flooded area and people would randomly be moving back and forth between high ground and the flooded area! 74 ... biology, chemistry--but that wasn't it. �r� l22l6fCsFnaRiOJFFNgOp8WbqT3OazJkM5GR5l2WPGIRERyCQfmp5d1HzF5D1TStN3vZljeGOoAk The experiments will include at least 20 labs, of which at least 6 will be inquiry-based labs.

Well chosen similar comparisons of ‘numbers’ for enthalpy and entropy values similarly lead to the generalizations stated above. PROCESS As kids we try to get away with as much as we can; if we have exceedingly easygoing parents, we get away with more than what we should.

Stable and unstable nuclei are discovered as are the ‘general’ rules for nuclear stability in terms of what elements are still present on earth and their origins (due to long half lives from the time of the formation of the second generation star). Since there are rules for all the matter, living and non-living, it would make sense that there are rules for how the fundamental building blocks of matter are put together. 154 We can however envision matter, given the right circumstances, ‘investigating’ other ways of organizing itself such that it ends up with a better combination of bonds and freedom of motion. ͐,.�. 241 As an aside I believe that how we use certain words sometimes gets in the way of a clear and consistent message (the careless use of ionization and dissociation comes to mind). ed5b00434 1..6 Depends on which side of the family that cousin comes from, doesn’t it? 12 0 obj ��w3T�PI�2T0 BCcC#=s#c��\.

Chemicals like humans are very adaptable. 123 Legs: the obvious extensions of this idea in later chemistry courses are all of quantum mechanics and nuclear chemistry. It arises from the study of the formulas of oxides and hydrides, the order of the elements in the formula and oxidation numbers. 178 Particle Nature of Matter. There is also the ‘reverse’ exercise for students: to look at a formula and classify it. Although I am quite strident about the importance of electronegativity and energy, I am less firmly committed to the other big ideas. There are always the same number of players on the ice for each team (forgetting for the moment penalty situations). However, we recognize that we have to balance security and freedom. 21uILaNLyKaVEaGSJAsiuGIOxGx7jfMDUaXJHIRRO7n6fVY5YwbHJg9ssmo+TfzL82LG0djryy/o I do not care for the slavish determination of ΔH or ΔG or ΔS values by reference to tables – that is accounting. 31 RGB 179 It covers phenomena where weak forces are in play: primarily phase transitions and solubility.

I also believe word choice is important. 45 AAIRAQMRAf/EAaIAAAAHAQEBAQEAAAAAAAAAAAQFAwIGAQAHCAkKCwEAAgIDAQEBAQEAAAAAAAAA endstream The relationship can be either “genetic’ or “social”. Indicators are an excellent way of demonstrating this idea: the system is showing one color and on the addition of the tiniest drop of a reagent are showing another color. ͐,.�. 66 104 endobj Elements in the same column are related to each other ‘genetically’; they have what are called common outer electronic configurations. Total Points. In this case the chemistry analogy overlaps perfectly. Big Ideas of Modeling Chemistry 1. 113 The same big idea in chemical terms follows. It takes an energy shove to go from a less stable to a more stable state but once something gets going, there is a momentum that keeps it going. eykC6Teatof5s2NmhkuZNSd44wKsxib1eKjuSEoMyOMQlhJ5cLRwGUcwHPiZ95L8/eVL7ydp982p So both nuclear and extended families can be large or small.

C=40 M=45 Y=50 K=5 166 Yet chopped down, put in a pile and ignited, they too return to carbon dioxide and water and minerals and give off a lot of energy as they burn. RGB endstream When I looked at these again, now seven years later, I wasn’t satisfied with how they were stated. 216 To recap, the AP Chemistry syllabus revolves around six "Big Ideas," which are main themes that cover more specific concepts called "Enduring Understandings." You may be an only child or you may have several siblings in your nuclear family. PROCESS Some are strong, like a 50 year marriage. endobj Chemical bonds happen because of what electrons are doing. Regardless, I offer this as a starting point for having a serious discussion about thinking about big ideas in chemistry and then working to incorporate those ideas into how we teach chemistry. PROCESS In general chemistry: The application of this big idea is obvious in terms of balanced equations: complete, net, ionic or redox. About ten years before I retired I had started working on a general chemistry storyline and in doing so developing my own textbook. One need only say nucleophilic and electrophilic to recognize its importance in organic chemistry. <>stream x�+� � | GRAY 28 RGB endstream Arbortext Advanced Print Publisher 10.0.1465/W Unicode K=80 That article was submitted the year after I retired and was a response to a submission questioning the utility of the Principle of Le Châtelier.

In this report, a group of scientists, engineers and science educators set out ten principles underpinning the science education of all students. endstream Come on! Gases with very low boiling points such as the noble gases have minimal attractions and maximum freedom of motion. The first of these gave a survey of an important topic with a significant chemical component: global warming. PROCESS Legs: There are obvious legs in general chemistry, some already mentioned above such as acids and bases; this extends into inorganic chemistry and additional ways to classify acids and bases and other substances. 5 0 obj It is critical to know how to make correct structures and correlate these structures to certain geometric shapes. Would it surprise you that all the elements were ‘born’ in some very special ‘wombs’ and that matter ‘evolved’ over time to what we encounter now? x�S�*�*T0T0 B�����i�����U�"� ��� There is homeostasis from biology. In this approach nuclei come first. RGB Tracy Schloemer | Sat, 10/08/2016 - 17:52 . RGB Our human big idea was ‘humans seek to maximize both security and freedom’. The negative sign makes sense if you think about the fact that you have to compromise security with freedom. Much of what constitutes chemical engineering is an application of this big idea.

I sometimes flippantly call this big idea ‘the effect of ratios, powers and logarithms’. 0 The interactions of chemicals pretty much cover the same ground. In general chemistry: The elaboration for the student is more detailed here than for the other big ideas. You should notice that heat or energy is involved in both these examples. This big idea starts with what is one, if not, the most important equation in all of science. <>>>/BBox[0 0 625.44 818.36]/Length 46>>stream It is my belief that the stand alone placement of ‘nuclear chemistry’, usually in one of the final chapters of most textbooks, is inappropriate.

But I do think it might serve as good starting point to work from to get the notion of big ideas into chemistry. In other words, these ideas had to have ‘legs’. For instance in the example of the flooding, if the humans behaved like substances not all would leave when the flooding started; in fact some from high ground would move into the flooded area and people would randomly be moving back and forth between high ground and the flooded area! 74 ... biology, chemistry--but that wasn't it. �r� l22l6fCsFnaRiOJFFNgOp8WbqT3OazJkM5GR5l2WPGIRERyCQfmp5d1HzF5D1TStN3vZljeGOoAk The experiments will include at least 20 labs, of which at least 6 will be inquiry-based labs.

Well chosen similar comparisons of ‘numbers’ for enthalpy and entropy values similarly lead to the generalizations stated above. PROCESS As kids we try to get away with as much as we can; if we have exceedingly easygoing parents, we get away with more than what we should.

Stable and unstable nuclei are discovered as are the ‘general’ rules for nuclear stability in terms of what elements are still present on earth and their origins (due to long half lives from the time of the formation of the second generation star). Since there are rules for all the matter, living and non-living, it would make sense that there are rules for how the fundamental building blocks of matter are put together. 154 We can however envision matter, given the right circumstances, ‘investigating’ other ways of organizing itself such that it ends up with a better combination of bonds and freedom of motion. ͐,.�. 241 As an aside I believe that how we use certain words sometimes gets in the way of a clear and consistent message (the careless use of ionization and dissociation comes to mind). ed5b00434 1..6 Depends on which side of the family that cousin comes from, doesn’t it? 12 0 obj ��w3T�PI�2T0 BCcC#=s#c��\.

Chemicals like humans are very adaptable. 123 Legs: the obvious extensions of this idea in later chemistry courses are all of quantum mechanics and nuclear chemistry. It arises from the study of the formulas of oxides and hydrides, the order of the elements in the formula and oxidation numbers. 178 Particle Nature of Matter. There is also the ‘reverse’ exercise for students: to look at a formula and classify it. Although I am quite strident about the importance of electronegativity and energy, I am less firmly committed to the other big ideas. There are always the same number of players on the ice for each team (forgetting for the moment penalty situations). However, we recognize that we have to balance security and freedom. 21uILaNLyKaVEaGSJAsiuGIOxGx7jfMDUaXJHIRRO7n6fVY5YwbHJg9ssmo+TfzL82LG0djryy/o I do not care for the slavish determination of ΔH or ΔG or ΔS values by reference to tables – that is accounting. 31 RGB 179 It covers phenomena where weak forces are in play: primarily phase transitions and solubility.

Total Points. In this case the chemistry analogy overlaps perfectly. Big Ideas of Modeling Chemistry 1. 113 The same big idea in chemical terms follows. It takes an energy shove to go from a less stable to a more stable state but once something gets going, there is a momentum that keeps it going. eykC6Teatof5s2NmhkuZNSd44wKsxib1eKjuSEoMyOMQlhJ5cLRwGUcwHPiZ95L8/eVL7ydp982p So both nuclear and extended families can be large or small.
