Look at this amazing chart we came up with!
On Tuesday and Wednesday, we explored with compasses and how they are related to magnets.
We closely examined compasses in small groups and wrote down some of the things we noticed:
-Compasses have an N, E, S, and W on them which stand for North, East, South, and West. There is also an NE, SE, SW, and SE in between each of the letters that stand for Northeast, Southeast, Southwest, and Northwest.
-The compass needle is two colors: the pointed half is red and the other half is white
-There are small numbers and lines around the compass. The largest number is 340 and then it goes back to 0.
-When you follow the red point, it leads you to the blue wall in our classroom
-the needle is magnetic, but the rest of the compass is not.
We talked about how you could use a compass to find your way to or from somewhere if you knew which direction you needed to head in, and we also talked about how things like phones and cars often have things like GPS which can also tell you which direction you are heading in!
On Thursday, we tested out whether or not magnets could work through solids and liquids the way they work through gas.
We discovered that if the two magnets were strong enough, they could work through just about anything! Our weaker magnets would work through some objects, but some of our solid objects were just a little too thick for the magnetic field to travel through them.
It has been a lot of fun to get back into the role of scientists! If friends find any more facts about magnets at home, feel free to share them at school!
