Show and Tell {Physics Class}

Although I still have Honduras pictures I'd like to share, I decided that for this week's Show & Tell with CanadaGirl I would show a little of what we've been doing in school.  Yes, we actually do school around here! And its amazing how when we are actually DOING school, I don't seem to have time to WRITE ABOUT school on this blog.  LOL

I shared a few pictures on the first day of school showing what we are working on in Science this year.  We are studying Physics.  We started out by learning about different types of motion and how objects move because of different forces acting upon them.

We studied the conservation of momentum by doing a demonstration very similar to a Newton's Cradle, using marbles and a book.

Landon did this worksheet showing how momentum is conserved and the calculations for it.

(I don't remember studying this when I was in Grade Four! LOL)

Then we learned about Force, including tensile strength and buoyancy.  We talked about how a bathroom scale works by measuring the force of gravity on a mass.

We learned a bit about how suspension bridges work as well.

 Next we studied Friction.  We tested our dining room floor, our living carpet, and a chunk of coarse sandpaper to see how much friction each would have against a block of wood.

Then we talked about Work.  Mechanical work!  We calculated the amount of work done by lifing different objects.  Its fun to have a chalkboard to show these formulas!  (I even got to write E=mc² one day, and it was totally in context!)

We've finished the first section of our textbook now, and have just started on the second section, so we are now studying simple machines.

So, as you can see from my very scholarly post today, sometimes I neglect blogging because we're having fun learning!

Wow! I like how the photos can show the principles! Good job!

Wow - you guys sure did science up GOOD this week!! Thanks so much for sharing all of that! Between you and Tina (solidrock), I may be inspired to actually teach science to my boys, instead of pretending it doesn't exist, LOL!

Oh, and I loved your explanation of how a scale works. I've never thought of it from that perspective: that it measures the force of gravity. My first thought was, a-ha!! So that weight isn't necessarily mine, it's gravity's!!! ROFL!!!

Have a lovely weekend!

Good job!

You've been busy! I did not know how bathroom scales work. Hm. I need less gravity.

Great job.

Wow, that was quite a lesson. How long did that take you? :-)

Awesome photos! They were great for explaining everything.

What a GREAT post !!! It is funny how many people are studing physics right now ! My oldest is !!

Thank you for sharing. It looks like you are having a BLAST.

Blessings and ((HUGS)) my SSiC

In Him<><

I don't remember doing that in 4th grade science either!!! I bet your kids loved it!!!

Your son looks like he has a great swing!!! (you're talking to a ball player!! : } I get distracted by those things!!! )

We just started our science this week in co-op and "I'M" loving it. How crazy is that?!

Thanks for sharing,

Wow! Great stuff!

I love comments! It's like visiting over a virtual cup of coffee.
