Slivers of Silver

When we added (AgNO3) to a strand of copper, silver solidified on the copper. It looked like branches. After a while we could we the liquid turn blue because the chemicals where sharing electrons, causing a chemical change. I liked this activity because we could see this silver branches expand and expand. It really helped me understand howbmetals can look and change.

No, alchemy is not real, you can’t make something out of nothing. Alchemists were just lying to their bosses. May be they did things like this experiment to trick their bosses.

Mutant Bees Project

I think A bees mutation is a positive mutation because the extra antennae make the bee more sensitive. Meaning that it can feel more things. 

 

I think B bees mutation is negative because it doesn’t have any wings. Given the fact that bees need to fly to live, I drew the conclusion that it’s a negative mutation.

I think C bees mutation is neutral because a bee dies once it stings someone. So the size of the stinger doesn’t matter. It’ll die any ways.

I think this activity was OK it demonstrated how mutations work, but it wasn’t really clear. It was fun though .

DNA Bracelet

20141007_095015DNA leads to protein like this: DNA is in the nucleus, inside the nucleus it is copied by mRNA. The mRNA seeps out through the pores of the nuclear membrane. Then the mRNA is grabbed by a Ribosome, the Ribosome reads the codons of the RNA. Codons are made up of three letters; each codon can consist on A, C, T, and/or G. Each codon (triplet) is an instruction for amino acids. When codons are read a specific amino acid is added to each of the letters. Amino Acids then make proteins.

This activity models codons and amino acids by giving us a visual representation of how they are ready by the ribosomes and how each letter co-relates with each other.

I think this activity is helpful because if you don’t understand how proteins and amino acids work you can use this as a visual guode. Furthermore, this activity is fairly easy to do and is fun. Which helps you remember the steps better. Plus, froot-loops are pretty delicious.
