Iditarod!

I chose Dallas Seavey as my musher to follow during the Iditarod.  He is a veteran musher from Virginia.  He is a third generation musher who grew up helping his dad with the dogs.  He ran the Junior Iditarod four times.  He is a high school state champion, a Junior Iditarod champion, and was the 2005 world champion.  I chose this musher because he is fast, so it will be a challenge for me to read faster to keep up with him!

 

Meeting a real musher was wonderful for us.  The first thing I saw was some cute huskies and the wooden sled.  I really liked how the sled moved.  The huskies’ fur was so soft, and it made me want to have one.  I couldn’t wait until we got to pet the dogs!  The wooden sled was cool, and it was very big.  The dogs had silky fur, and they had a good nose.  I loved them, and I want to do the Iditarod too.  It was fun, and the dogs were so cute.  I especially liked getting to pull the sled.  Thank you, Mrs. Guertin, for letting us see your dogs!

The Speeding Sled

I hear the screeching ice.

I scatch the frozen water, and I ride in the wind.

I ride on the unfaceable trail,

Seeing dancing flakes on my face

And beautiful dogs attached to me.

I see them scampering in the jagged snow.

Oh, I’m hoping we win

So I can see my musher so happy!

I am the Iditarod sled.

Ice Cube Keeper Engineering Challenge

Ice Cube Keeper Engineering Challenge

Ask: Would adding snow to my ice cube keeper probably keep it colder?

Next, we imagined what our ice cube keeper would look like, planned, and created it.

I predict that my ice cube will stay frozen 6 hours.

My table:

Time: Measurement: Observations:
9:25 2 cm. tall

4 cm. wide

It is like an oval.
10:10 4 cm.  
11:30 4 cm. It is wet now.
12:05 4 cm. It has something white in it.
1:10 4 cm. The snow melted.
2:35

 

3:00

4 cm.

 

4 cm. but skinny

Just water around it now.

Almost melted.

I might try this to keep my ice cube from melting as soon as it did. My reflections: The snow helped the ice keep cold because when you put something over it, it becomes cold in the thing that you put on the ice. Tape helped the cold keep inside the box. The box that you put on the ice is very small, so it only goes to the ice not somewhere else. Holes make heat come inside the box and let the cold air out. Water made the ice melt fast. Putting more foam and more tape so that no heat comes in the box were strategies that worked in a lot of the ice cube keepers. I could improve my keeper by getting a bigger tub to put more snow in it. I could make the foam lighter so that it does not absorb a lot of light.

Engineering Project: Sewing!

Sewing helps our students grow in a number of the Next Generation Science Standards. Here is one example. 3-5-ETS1-2. “Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.” Thank you, Mrs. Shedd, for providing this amazing STEM opportunity. We love it here!

Energy Experiment

I stacked the cups like a castle.  Then we stacked four, then three, then two, then one.  My prediction was that faster things have more energy.  The ball had more energy to knock more cups down when it went fast.  My conclusion was that my prediction was right.
