Week 12

 

This week we conducted several experiments on several different objects. Many of these tests I have completed in my previous science classes, but something new our group used was an overflow cup to measure mass. This methos is used when you are measuring an object that is too large to fit in what you are using to measure the mass. You fill the overflow cup with water and once it stops overflowing from the faucet on the side you measure the amount of water in the cylinder and then add the object and once it stops overflowing again you will remeasure. Then, take the first measurement subtracted from the second and that is your final mass of the object.
When we were trying to conduct electricity with each object the one we assumed would work well was the paperclip. Our first two paperclips did not conduct electricity but when we received two new paperclips, they both conducted electricity. This was very weird to me especially since no other group experienced that issue. Why did our first two paperclips not work?

Week 7

 This week we learned about DNA which contains the genetic information that is necessary for an organism to develop and function. We did an activity where you flipped a coin to see what traits the person was going to have, heads was dominant and tails was recessive. If both or one of the parents has the dominant trait the child will receive that, to get the recessive trait both parents must have it.  The activity would be good to use in a future classroom when teaching students about DNA and genetic makeup. One remaining question I have is if there is a possibility for a child to get a recessive trait if neither of the parents have it.

This week we looked at the seeds we planted in the cups last week. When we pulled the cups out of the fast planter the seeds began to sprout.  We then learned the life cycle of multiple animals and my group researched the life cycle of a flower. A flower begins as a seed, turns to a sprout, then grows to a young flower, and matures into an adult flower. I already knew this information, but I was surprised that a life cycle is only complete if there is four or more steps not less.  The project we did on the plate with playdoh kept me intrigued and I think it would be a good lesson to incorporate into my future classroom. This will allow them to learn about life cycles through a hands-on lesson. We then took a quad planter and added fertilizer, soil, seed, and water and placed this into the fast planter.

  This week in lab, I learned that structural changes to genes, known as mutations, can impact proteins and may lead to harmful, beneficial, or neutral effects on an organism's structure of function. Mutations involve changes in the DNA sequence, whether it is a nucleotide or base. I also gained a deeper understanding of how DNA codes for proteins. Every three bases form a codon, which corresponds to a specific amino acid which is often referred to as the building blocks of proteins. These three-letter sequences provide the instructions for assembling proteins one step at a time, with certain codons signaling when to start or stop the process.  Our discussion on genotypes and phenotypes was easily connected to what we have been learning in lab and lecture over the past few weeks. Genotypes refer to the combination of alleles inherited from parents for a specific gene, while phenotypes are the observable characteristics or traits that result from gene expression. Other influenc...
