1. Sorting and classifying matter Students made observations of several different substances and classified them into the groups shown above. Which of the following materials should be classified into Group 2 in this chart? AGlass BGranite CLemonade DPlastic Group 1Group 2Group 3 WoodWaterHelium IronNitrogen

2. Which of the objects above would not conduct electricity? A metal hanger B copper tubing C glass tube D paper clip

3. Learning targets I know that matter has measurable physical properties and those properties determine how matter is classified, changed, and used. I am expected to classify matter based on physical properties, including mass, magnetism, physical state (solid, liquid, and gas), relative density (sinking and floating), solubility in water, and the ability to conduct or insulate thermal energy or electric energy.

5. Magnetism Magnet- An object that creates a force that can attract and repel certain objects – Kind of like selective gravity Magnetism-A force (push or a pull) that acts only on magnetic objects

6. Magnetic sorting** First we will be testing a variety of objects to see what is magnetic and what isn’t. Make a prediction before you begin testing. Create a T chart in your journal to sort them. Did anything surprise you?

7. Wait… what Were all the different pieces of metal magnetic? Was it only the metal that was magnetic?

8. Magnetic rock?? Special type of rock named… Magnetite – Not all magnetite attracts metal like a magnet – Must be charged by a lightning strikes magnetic field – Becomes “Loadstone” – Original first compass – Only naturally occurring permanent magnet

9. Permanent magnet? Most magnets we see are man made permanent magnets You can make a temporary magnet however, – Observe….

10. Magnetism video

11. Magnetism day 2: warm up Which object would most likely be attracted to a magnet? Asilver coin Bcopper wire Ciron doorknob Daluminum key

12. Who likes magnets? Nic likes magnets!!! Nickel Iron Cobalt

13. Scientific method: Magnetism Today we are going to design an experiment that helps us answer a question. Large focus on the scientific method. Each group will focus on designing an experiment to answer a question about magnets. We will design today and test tomorrow Only those that are on task will be allowed to participate in the activity

14. Magnetism: scientific method Observation: not all magnets have the same strength Question: which type of magnet is the strongest? Hypothesis: I think that the _______ magnet will be the strongest because________ Design a test: Perform a test: Results: record your results in a table

15. Good vs. needs work examples

19. Things to think about when designing a test Tools available (you may not need all of them) Variable: what you are testing, this should be the only thing that changes between test (type of magnet) Control: Everything else must stay the same – Must test the same way – No other factor besides the strength of the magnet should contribute to the results*

20. Tools available -You may decide you do not need all the supplies for the test you design - Ruler -2 workbooks -1 magnetic object* ?? -3 magnets -bar -Donut* ?? -ball

22. Results table example Magnet typeFarthest Distance that it works (mm) trial 1 trial 2trial 3 Ruler method: 1.Place brad at 0 line of cm side of ruler 2.Place magnet at the opposite end of the ruler 3.Slowly slide the magnet along the ruler 4.When the brad begins to be effected by the magnet, record your result 5.Repeat for each magnet and each 3 trials. Book page method 1.Place brad on the top of a book 2.Count how many pages the magnetic force will effect the magnet through 3.Repeat the steps for each magnet and repeat for each of the 3 trials
