Learners connect J.J. Thomson’s work with discovery of electrons and related experiments, connect E. Goldstein to observations involving low-pressure gases and beams, and place the plum pudding model as an early description of atomic structure.

Her display has sections on J.J. Thomson, E. Goldstein and the plum pudding model.  \nCan you help decide which labels should go with which section?  \nLabels  \n\n| 1. This scientist conducted similar experiments to J.J. Thomson. | 2. He applied voltage to a lowpressure gas and he saw abeam of light moving in a straight line. He deduced it made of negatively charged particles. | 3. This atomic model was proposed by Thomson in 1904. |\n| --- | --- | --- |\n| 4. This scientist discovered electrons. | 5. He observed a beam travelling in the opposite direction to the electron. | 6. The atom is composed of electrons surrounded by a“soup” of positive charge. |\n| 7. It was called this because the model resembled a dessert that was popular atthe time. | 8. He also discovered that electrons are 1840 times lighter than the most basic atom. | 9. He had discovered protons. |\n\n\n| J.J. Thomson | E Goldstein | Plum pudding model |\n| --- | --- | --- |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n\nTEACHER’S NOTES  \nThere are two different ways this activity can be done, depending on whether it’s done in class or as homework.  \nFOR HOMEWORK:  \n- The students work individually.  \n- They follow the instructions indicated in the activity.  \n- You can suggest the students underline any words they don’t know and look them up if they can’t work out the meaning from the context.  \nIN CLASS:  \nSet up:  \n- The students can work in pairs.  \n- Make sure everyone has understood the task.  \n- Explain the time limit they have to complete the activity.  \nReview:  \n- If you use a projector in class or a digital board that allows writing interaction, you can ask students to write the answer on it. You can also encourage them to highlight any tricky words they find and check if these words were also hard for other students.  \n- If there is a group that has finished early you can give them an extra challenge, for example: Can you write a new fact for each of the sections in the display?  \nANSWER KEY  \n\n| J.J. Thomson | E Goldstein | Plum pudding model |\n| --- | --- | --- |\n| 2. He applied voltage to a low-pressure gas and he sawa beam of light moving in a straight line.
