Sledding January 4. 2015

Sledding 
January 4. 2015

Monday was a perfect day for sledding and hiking; so we seized the opportunity.  The temperatures were not too cold, and we were able to be outside for a good while without getting too cold.  I brought my camera and got a lot of fun pictures, and posted some here to share Michigan with our friends.  Here is a sampling of the woods in Michigan!  Part of our property is a older grove of Spruce trees, that is part of the reason I loved this property.  From what I understand, Grand Rapids was a major furniture building spot back in the 1800's.  The loggers pretty much lodged all the old timber---horrible.  So, people came through all the barren landscapes and mass planted trees---like these Spruce.  They are all planted in line, and very organized--which is so strange for the "woods" to be organized.  I'm glad they planted more trees to make up for all the logging that had happened here.


Dd clinging onto a tree as she prepares to get seated for her first ride of the day.  What a steep hill---scary!  But we both survived!

Our dog is very "dim" and nearly killed herself repeatedly as she careened down these hills.  Next time, I think we should leave her at home...at least until she figures out how to turn faster as she is approaching trees! Yikes!


We brought two sleds, but the previous owner left quite a few in their garage.  Their sleds worked better than ours!






This trail isn't as steep, but the trail is narrower...we have two paths to sled down, so far.



After we sledded, we decided to take a nice hike to explore.  We saw turkey prints in the snow---that was interesting.  There were lots of other prints that were 'normal'---deer, mice, rabbits, opossums...etc. 










I thought this looked really interesting.

Dd somehow chopped this tree in half last week, and then made herself a 'chair' by hammering nails to hold the back rest for her chair.  It doesn't look very comfy, but she was happy.

Fun day!

General Science Apologia Module 2

General Science Apologia Module 2 
Week 18 C (Jan 4-9, 2016)



Experiment 2.1Air Resistance differs due to the size and shape of an object.  Air resistance refers to the fact that air actually slows objects down as they fall.  The heavier an object is the less it is affected by air resistance.
This was a fun experiment, but I didn't take a big series of photo's to show all we did.  I thought it would just be easier to type out a quick description.
We tested and compared how fast two objects fell.  Standing on our chair (Officer Buckle and Gloria, would not be pleased!) we dropped two objects to see which hit the ground first.
Typing paper vs cardstock paper
Typing paper vs cardboard
Typing paper vs crumpled up typing paper
Typing paper vs a paperclip
Book and cardboard


The point was to learn how the weight of something, and the shape (surface area) will effect how quickly things would fall.  Gravity effects heavier object more than light objects.....Dd didn't find this experiment very fun, but I had a good time!  We did this experiment two days in a row, b/c on day two *I* wanted to give it a go!  When Dd dropped things she only dropped them 2-3 feet, but I got up on chair and lifted each thing up to the ceiling so the objects would have a lot more time falling.  I wanted to see if having a longer fall would change the results, and it kinda did.  Dd's falling papers were very close to landing at exactly the same time, but when given more time the landings were more divided.

 


Experiment 2.1  The Scientific Method




This experiment was just using our deductive reasoning skills.  The notes had me do various things to make the flashlight not work, and then Dd had to figure out what I had done and fix it.  This picture was when I put a piece of paper between the top connection and the battery, so the current couldn't flow.  Dd guessed what I was going to do before I did it...



After pulling out the paper, the light worked again

This was when I put tape over the connector to stop the current, Dd made her hypothesis from observing the possible problem, then she made a theory and removed the tape and she tested to see if that fixed the problem, and it did!

We learned:

The Scientific Method:
Starts with an OBSERVATION,
followed by the formulation of an educated explanation called HYPOTHESIS
Consistent Testing of a significant amount of data leads to a
THEORY
Finally this is confirmed by many experimental tests that are consistent with generations of data.
