Week 10- Posts 1-3

What have you done?

I have completed magnetism activities 5 and 7 and ensured that all the questions from previous activities have been discussed and answered.

What have you learned? 

We have learned a number of new things this week. First of all, we learned that magnets act in a field of space rather than by direct contact. We know this because when you place a metal object near a magnet, the object is drawn to, and is often pulled toward the magnet. All of this occurs without direct contact. Second of all, we learned what ferrofluid is. It is a mixture made of nano-sized iron oxide particles submersed in oil. It too, can be magnetized, due to iron's ferromagnetic properties. That is why it is called ferrofluid.

How will this help you later on in the unit? 

The information that we have learned will help us to understand what magnetism is and its properties. This information establishes a foundation that will help us to complete the upcoming labs, that go more in-depth and need for a strong basic understanding of magnetism.

What I plan to do next: 

Day 1: Finish answering questions for investigation 7  Home: work on practice problems

Day 2: Meet with group to do revisions on Circuits project  Home: Finish Revisions

Day 3: Hand in revisions and work on practice problems  Home: Practice Problems

Week 9- Posts 1-3

What have you done? 

I have completed the magnetism activities 3-4 and have begun to work on revisions for the circuits project, with my partner Ray.



What have you learned? 

After completing magnetism activities 3 and 4, I have learned several new things. First of all, I learned that it is possible to temporarily magnetize objects, using magnets. If you run a magnet over another metal object several times, you are able to transfer some magnetic energy from the magnet, over to the object. You are also able to establish poles, thus temporarily magnetizing the object. I also learned that one can easily disrupt the objects magnetic qualities, just as easily as magnetizing it. If you drop the object or use it to attract other objects too much, the objects magnetic qualities are almost completely disrupted or weakened to the point that they can no longer attract or repel other metal objects.



How will what you learned help you later on in the unit 


All of what I have learned will help me to understand what magnetism is and how it works. If I am able to understand that, then I will be able to understand the unit as well as do well on the assessments. 

What you plan to do next: 

Day 1: Work on Magnetism activity 4 + answer questions  Home: finish all questions 

Day 2:  work on Magnetism Activity 5     Home: answer all questions 

Day 3: Work on Activity 6 or finish any remaining work  Home: work on redo for project
