每週 2-4 小時. In order for each student to determine their own level of understanding of the High School Physics I will provide free of charge and outside of the sixty (60) minutes class questions to be answered. This of course is optional and solely based on the individual student. I would urge ALL students to answer as many questions as possible so that they would know where they need to improve, but it is optional.評估
Every class will have questions to be answered outside of the sixty (60) minutes class. This questions and answers will be done free of charge, as it will not be part of the sixty (60) minutes class.我們無法翻譯此文，請刷新頁面並再試一次。

The specific features provided by the documents used in my presentation are as follows:- 1. It acts as a companion to the student who needs to be familiar with the content of each topic and with the skills required to master the content. 2. It presents the material in a well-sequenced and coherent form, so that critical understandings are addressed, while developing a sound foundation. 3. The material has aesthetic appeal through the use of color, diagrams, tables and graphic displays. This will facilitate all learning styles, especially the visual and multi-sensory learner. 4. There is a wide range of worked examples to guide the students on how a topic is tested at the examination level. These examples vary in terms of content and difficulty level. 5. The examples also provide model solutions, so that students are guided in how to construct proper responses questions. This session will take nine (9) classes to complete. It will deal with the following:- 1. Class 1 – Model of the Atom 2. Class 2 & 3 – Structure of the Atom 3. Class 4 & 5 – Emissions from the Nucleus 4. Class 6 & 7 – Half-Life 5. Class 8 & 9 - Energy from the Nucleus. I will teach each of the nine (9) classes for forty (40) minutes each and then I will open the class for any questions to be asked. If there are no questions I will continue teaching the class. This class will be presented using a PDF document that I will share via ZOOM (Outschool). I will share the pdf document at the end of the class via Outschool 'email system'. Students should have a basic understanding of Physics, but it is not necessary. As an Engineer I will explain Physics in a VERY SIMPLE manner that each student will be able to learn Physics from 0% to 100%.
學習目標
1. Model of the Atom
a. describe the work done by Dalton, Thomson, Rutherford, Chadwick and Bohr in establishing the modern view of the atom
b. describe the Geiger–Marsden experiment, which established the nuclear structure of the atom
c. recall that the nucleus contains positively charged particles (protons) and neutral particles (neutrons) of approximately equal mass
d. state the approximate size of an atom
2. Structure of the Atom
a. sketch the structure of simple atoms
b. compare the charge and mass of the electron with the charge and mass of the proton
c. explain why an atom is normally neutral and stable
d. represent diagrammatically the structure of simple atoms
e. relate the shell model of the atom to the Periodic Table
f. recall that an atom of any element in the Periodic Table has one more proton than an atom of the element before it
g. recall and use the relationship A = Z + N
h. use the standard notation for representing a nuclide
i. explain what is meant by the term ‘isotope’
3. Emmission from the Nucleus
a. describe Marie Curie’s work in the field of radioactivity
b. recall that the decay process is independent of conditions outside the nucleus
c. discuss the need for safety measures in handling and using radio-isotopes
d. describe how a cloud chamber works
e. describe how a Geiger–Muller tube works
f. recall the nature of the three types of emissions from radioactive substances
g. describe experiments to compare the ranges of alpha, beta and gamma emissions in various media
h. predict the effects of magnetic and electric fields on the motion of alpha and beta particles and gamma rays
i. describe the appearance of the tracks of radioactive emissions in a cloud chamber
j. associate radioactivity with nuclear instability
k. represent and interpret nuclear reactions of the form
l. discuss the uses and dangers associated with emissions from the nucleus
4. Half Life
a. describe an experiment from which a radioactive decay curve can be obtained
b. define the term ‘half-life’
c. perform analogue experiments to illustrate random ‘decay’ processes
d. use graphs of random decay to show that such processes have a constant half-life
e. work through simple problems on half-life
f. discuss the useful applications of radio-isotopes
5. Energy from the Nucleus
a. associate the release of energy in a nuclear reaction with a change in mass
b. work out problems using Einstein’s equation E = mc2
c. relate the processes of fi ssion and fusion to E = mc2
d. describe the main features of a nuclear power plant and the significance of critical mass
e. discuss problems associated with the operation of a nuclear power plant
f. discuss problems posed by radioactive waste
g. advance arguments for and against the utilisation of nuclear energy
其他詳情
父母的引導和規範
I will present experiments via the document that I will be teaching from and some experiments if conducted may need parental supervision. These experiments do not need to be executed and are just for knowledge. But if a student has the capability to execute then they are free to do so. These experiments are usually conducted in a lab which is a controlled environment. If a student does not have a safe environment to conduct a parent should NOT allow any student to conduct any experiments.
