Presentation Transcript

  1. 12/2/13 Topic: Introduction to Magnets Do Now Name at least two uses of magnets. Explain, in your own words, what a magnet is. Name at least two uses of electricity. Explain, in your own words, what electricity is.

  2. Unit Question How are electricity and magnetism related? What is similar? What is different?

  3. Team Word Splash Electricity Magnetism

  4. Learning about magnetism! Go to the link on the wiki: http://www.ndt-ed.org/EducationResources/HighSchool/Magnetism/magneticproperties.htm Work through the first three sections. Read the text and play with the animations! Create one google document (or answer on paper) for your group. Answer the questions in “Magnetic Properties” and “Magnetic Behavior”.

  5. 12/3/13 Topic: Magnetism Lab Do Now If you have two magnets, the north pole and south pole will __________ each other. If you have two magnets, the north pole and north pole will __________ each other. What causes a material to be magnetic? What is a ferromagnetic material?

  6. Lab Steps • Create data table on your paper. • Pick your first object. Fill out the data table for this object. • Test if the object is a magnet, magnetic, ferromagnetic, or non-magnetic. • Test all 10 objects. Add all 10 to data table. • Answer follow up questions!!

  7. 12/4/13 Topic: Magnetic Strength Lab Do Now Name three things that you learned during yesterday’s exploration (in class with magnets). Take out a piece of paper for today’s lab. Make sure it is paper you can turn in.

  8. WLPCS Teresa Dobler Science D 12/4/13 Measuring Magnet Strength Lab Partners: Maddy, Zoe, Kim Introduction The purpose of this lab is to find the strength of magnets. In this lab we will answer the following question: As we add more magnets, what will happen to the magnetic strength? Our independent variable is the number of magnets. The dependent variable is the number of washers the paperclip can hold. We will keep the cups, the popsicle stick, the paper clip, the size and type of magnet, and the type, size, and weight of the washers. This lab is about magnets. A magnet is an object with a magnetic pull. An object is magnetic if it has iron.

  9. Teresa Dobler Science C 12/4/13 Measuring Magnet Strength Lab Partners: Chance, Duncan Introduction The purpose of our lab is to test the strength of magnets. We will answer the following question: As we add more magnets, what will happen to the magnetic strength? Our independent variable is how many magnets are being used. Our dependent variable is how many washers the paperclip can hold. We will keep the type of magnet, the size of the washers, the paperclip, the popsicle stick, and the cup constant. This lab is about magnets. A magnet is an object that has a magnetic pull. An object is magnetic if it contains iron.

  10. Teresa Dobler 12/4/2013 Science A Measuring Magnet Strength Lab Partners: Pre-Lab Question: You can tell a magnet is too strong if _____. You can tell a magnet is too weak if _____. Introduction The purpose of this lab is to measure the strength of magnets. We will answer the question: As we add more magnets, what will happen to the magnetic strength? Our independent variable is how many magnets are used. Our dependent variable is how many washers can stay on the paperclip before it falls down. We will keep the type of magnet, the paperclip, the cups, the popsicle stick, the weight of the washers, and the surface we are working on constant. This lab is about magnets, which are objects that repel or attract other magnets. Magnetism is a force that attracts objects with iron in them.

  11. Teresa Dobler Science E 12/4/13 Measuring Magnet Strength Lab Partners: Abe, Owen, Dante Introduction The purpose of this lab is to learn about magnetic strength. We will answer the following question: As we add more magnets, what will happen to the magnetic strength? The independent variable is the amount of magnets we use. The dependent variable is the number of washers that are held on the paperclip before it falls. We will keep the cups, the size of the magnets, the type of magnet, the paperclip, the popsicle, and the size and weight of the washers is kept constant. Some key vocabulary you may need to know in order to do this experiment is magnet, magnetism, and washer. A magnet is an object that attracts and repels other magnets. Magnetism is a force that attracts objects with iron. A washer is a round, steel disk with a hole in the center.

  12. WLPCS Teresa Dobler Science F 12/4/2013 Measuring Magnet Strength Lab Partners: Trinity, Sofia, Emilia Introduction The purpose of this experiment is to see how many magnets is too much or too little to hold something together. We are measuring the strength of magnets by testing how many washers one magnet, two magnets, etc can hold. The independent variable is the number of magnets. The dependent variable is the number of washers a paperclip can hold before it falls. We will keep the size of the washers, the type of magnet, the height of the cups, the size of the paperclip, and the location constant. Some vocabulary words in this lab are magnetism and magnet. Magnetism is a force that attracts iron. A magnet is an object that has a magnetic pull.

  13. Magnetic Field lines • Magnetic field lines always travel from the NORTH pole to the SOUTH pole. • The magnetic field is stronger when the lines are closer together.

  14. More Examples

  15. Todays exploration Part 1 Pick a magnet from the front table. • Draw a detailed diagram of the magnet – comment on the size, shape, color, etc) • Hold the magnet underneath the iron filings. • Do not allow the magnet to touch the iron filings – both will be ruined if you do. • In your lab notebook, draw a diagram showing what the magnetic field lines look like. • Repeat the steps above with two more different magnets! Part 2: Take two or more magnets. Draw both magnets. Then, place both under the iron filings at the same time. Draw a diagram showing what the magnetic field lines look like. Repeat part 2 again if time permits.

  16. Follow up Questions – Answer in below diagrams Directions: Write the question number, then answer the question. • Is there a relationship between the shape of the magnet and the shape of the magnetic field? Explain. • What was different when you used more than one magnet?

  17. 12/5/13 • Topic: Strength of a Magnet Lab • *Take out any science fair materials you need to turn in. Make sure your NAME is on everything. Keep on your desk!! • Do Now • Take out your lab from yesterday – pick up where you left off! • Finish Data! • Graph! • Conclusion!
