Working With Polymers

One lab we did this last quarter was working with polymers.  We had to get the right amount of borax and glue to make the polymer stretchy, and you had to be able to put your hand it it and take your hand out and have nothing on your hand.  Lachlan and I didn't get it right, but one group in our class did.  Before the experiment, I thought the borax was water and I was wanted to drink it.  But when Ms Pro told us it wasn't water, I didn't want to anymore.  This is an example of how looks can be deceiving and haw you shouldn't assume anything if your not entirely sure.

We got pretty close to getting the slime right. We settled for my mixture.  I don't know what number of stuff we put in.  We tried to make the other ones the same, but one turned into a slightly worse polymer, one turned into a "fixiey liquid", and the other one... I don't know.

I don't have a picture of my slime.

One polymer commonly found in homes is silly putty.

  Another is rubber, used in car tires.  Perspex is in calculator screens.

.  One that isn't so common is Kevlar, which is in bulletproof vests.

Science Class:SEMESTER_REFLECTION

This past quarter we worked with atoms and states of matter.  I already knew that there were such thing as the quarks, and I was disappointing to learn that we wouldn't be learning about them.  Anyway, what i did learn, was the charges of the parts of atoms: Proton/Positive Neutron/no charge Electron/negative.

November Reflection

I think that I am the best at dividing fractions.  It’s really simple to me.  But, that’s DOING math not MATHEMATICAL THINKING.  Yes, there’s a difference.  Doing math is just doing an algorithm without think about why.  But, thinking mathematically, you wonder why you do something.  One strength I have as a mathematician is that I always put different numbers in place of the #s and make up new problems.  This is a sign of the core value of curious.  I am sometimes shaky at division so I have someone at home help me.  I don’t have a tutor, I have my MOM!  She was a math teacher and that’s good.
