Nuclear Chemistry Basics: Subatomic Particle Review

1. EDU 557 Final Project and Presentation Option 2: Develop Supplemental Curricula Daniel R. Barnes Concordia Univeristy Begun 4/21/2013 Due 5/2/2013 NOTE: I stole a few images from the world wide web to make this presentation. Please do not copy or distribute this file.

3. Okay. You can click the mouse button or something now. Please do not press any buttons for the moment . Just watch the images.

4. Hi! My name is Dan! Welcome to my PowerPoint! The next slide is designed to provide a test of the readability of various sizes of two popular fonts. It is the hope of the author that he can sneak a look at somebody’s iPad, somebody else’s smart phone, and somebody else’s tricorder to see how readable the various letter sizes are on these different input/output devices.

6. So anyway . . . This interactive power point attempts to prepare students for a unit on nuclear events (radioactive decay, nuclear fission, nuclear fusion) by making sure that they have all prerequisite basic knowledge about the atom and the subatomic particles that make it up. The factual knowledge tested for throughout the presentation is material taught much earlier in the year. By the time nuclear chemistry is taught, this material has had a long time to become dormant, rusty, and covered with cobwebs. For those who know well the basics about atomic structure, iteration through the presentation will be rapid, allowing them to move on to the main lesson with only minimal delay. Those who need more remediation will spend an amount of time wandering through the halls and corridors of this presentation that is in proportion to their need.

7. Scaffolding in the form of colorful visual images caters to visual learners. Spanish translations upon request provide support for English learners. (Realistically speaking, Spanish is, overwhelmingly, the first language spoken by most EL’s in the Centinela Valley Union High School District.) The mouse-click-driven nature of the presentation should appeal to tactile-kinesthetic learners and those who fall asleep easily.

8. The following slide, while conveying the original vision of the device more than its current character, nonetheless may be quite effective at triggering epileptic seizures . . .

15. Yes. The electron is much less massive than the proton or neutron. In fact, its mass is so low that electrons are not counted when determining the mass number of an atom. meep - + Click anywhere to continue

17. Click the particle that has no electric charge. + - proton neutron electron Electric charge = 0 (neutral) Electric charge = +1 Electrical charge = -1

18. Yes. The neutron has no electric charge. The neutron’s electric charge is zero. The neutron is neutral. It feels no electric forces, either attractive or repulsive. Should I care? + - Click anywhere to continue

35. What is found in the center of an atom? ? No entiendo todas estas palabras en inglés. Electrons DNA A nucleus

36. Not quite. Electrons are found on the outside of the atom. Electrons “orbit” the nucleus. The “nucleus” is in the middle. Please click the nucleus to proceed. The nucleus is the thing in the middle. Please click it.

37. Ask your teacher for help.

38. Los libros “are found” (se encuentran) en una biblioteca. El agua “is found” en un lago. Los zapatos “are found” en los pies de las personas. El "center" de algo está en el medio de esa cosa. Un “atom" es una pequeña partícula de materia. Todo está hecho de átomos. Los átomos son muy pequeños. Un átomo tiene un “nucleus" en su centro. I am ready for the question now. Los electrones "orbit" el núcleo de un átomo de la forma en que la tierra gira alrededor del sol.

39. Ask your teacher for help.

40. I think you may be confusing cells and atoms. Cells are very small. Cells are so small that you need a microscope to see them. However, atoms are MUCH smaller than cells. A cell is a living thing. Lots of cells, including the cells in your body, have a “nucleus” in the middle. The nucleus is sort of a tiny water balloon that has DNA molecules in it. The DNA gives orders that tell the cell what to do. Therefore, the nucleus is called the “brain” of the cell.

41. DNA is made of molecules, and molecules are made of atoms, so atoms are MUCH smaller than cells. Atoms are smaller than DNA molecules, so it’s impossible for an atom to have DNA in its center. That would be like Los Angeles having California in its center. It doesn’t make any sense. California is bigger than Los Angeles. Los Angeles is just part of California. Give me the question again. I’m ready now.

42. Ask your teacher for help.

43. Good Job. A “nucleus” is found in the center of every atom.

44. What is an atomic nucleus made of? ? No entiendo todas estas palabras en inglés. Protons and neutrons Molecules Electrons and protons

45. Un “atom" es una pequeña partícula de materia. Todo está hecho de átomos. Los átomos son muy pequeños. La definicion de la palabra “atomic" es “de o tener que ver con un átomo“. Un átomo tiene un “nucleus" en su centro. Muchas mesas y sillas “are made of” (son de) madera. Los pantalones y las camisas “are made of” (están hechas de) tela. I am ready for the question now. Un matrimonio “is made of” (está hecho de) un esposo y una esposa.

46. Ask your teacher for help.

47. Atoms aren’t made of molecules. Molecules are made of atoms! An atom is made of a nucleus with electrons orbiting it. H H hydrogen atom C H H C carbon atom H methane molecule Give me the question again. I’m ready now. A nucleus is made of protons and neutrons.

48. Ask your teacher for help.
