matter and measurement post 4

I finished making my treat for tomorrow! And today was the test, I originally felt very confident on my test but thinking back on it I realized I made very simple mistakes, that are very frustrating. Oh well, at least my cupcakes are cute and halloween ish.

I am very nervous for my test tomorrow, but I am semi distracted because I am having lots of fun making my special treat and converting standard measurements to metric measurements for class on friday! It is defiantly helping my re-enforce conversion for my test tomorrow.

I Love learning about solid liquids and gases because it is very easy and a beautiful break from some complicating chemistry. Solids liquids gases are all review but I am learning about their dimensional analysis which is a fun interesting change to something new I have never done.

Atomic structure and radio activity post 11

These are some cool links that really helped me during this unit to just go over everything and tie it all together!

Alpha Beta Gama decay
half lives
Daltons atomic theory
proton neutron and electron count
mass percentage abundance formula
decay and half life

Atomic structure and radioactivity post 8

Today we learned about half-lives and i finally learned that in half lives nothing disappears the half life represents the part that is still radioactive, but nothing actually goes away like I originally thought. This is the picture of us in lab today. We cut up lots of pieces of paper and dumped them out. The ones landing on colored side were the ones that were radioactive. The white ones were the decayed ones. We continued this process multiple times.

This is a picture of a lab we did in class. We learned about radioactivity. We cut up lots of squares of paper one side was colored and one was white. When we shook them up and dumped them out, the yellow represented the ones tht decayed. It was very fun and really helped me understand half life. the only draw back was having to cut out all those squares. it took forever!

well..... that was an interesting test. I felt like i knew all the alpha gama abd beta decays. The graphs were very easy and so was the nomenclature. I found out i really struggle with half lifes and i definatly need to study that for next time.
