1. Recognize macromolecules 2.2.3 Biochemistry of food
The Biochemistry of Food lab is one that helped me learn about the many different types of macromolecules we consume every day. Each type of macromolecule plays a different role in the body. We analyzed the many types of molecules including: carbohydrates, proteins, lipids, and nucleic acids. We also broke down the chemical structures by using 3d models and sketching pictures in our lab books. Now after doing this activity, I can recognize the structures of the different macromolecules and also understand more about how each molecule plays a role in my health. Now when I eat foods I can think of the macromolecules that are in them which is very interesting!
2. Recognize Regulating blood sugar is vital 2.3.3 Complications of diabetes
In The Complications of Diabetes Lab we learned about the many complications that can occur as a result of diabetes and high blood sugar. In the activity, we filled out the body diagram shown on the left by taking data from the other lab groups to have a complete picture of the widespread effects of high blood sugar on the body. Before doing this activity I didn't understand why diabetes can cause such a wide variety of problems in the body. Now after this lab I know how high blood glucose levels damage the blood vessels in the cardiovascular system which is connected to many of the other body systems. This lab also demonstrates how vitally important it is to regulate blood sugar levels and keep them stable in order to avoid the many serious complications that can occur as well as diabetic emergencies.

3. Compare & Contrast Type 1 and Type 2 Diabetes 2.1.1 Diagnosing Diabetes
In the Diagnosing Diabetes lab we learned about the differences between type 1 and type 2 diabetics. We also performed insulin and glucose tests to more clearly identify the differences between type 1 and type 2 diabetes. Before this lab I really didn't know barely anything about what diabetes was. All I knew was that they had to monitor their blood sugar. Now I know the ins and outs of diabetes as well as can tell the difference between the symptoms of a type 1 diabetic vs type 2 diabetic. The glucose test was a way to tell if someone had diabetes or not, and the insulin test helped determine if the body was producing insulin but having problems, (type 2) or if the body wasn't producing any insulin at all(type 1).
4. Describe Dna structure 1.2.3 Dna analysis
In the 1.2.3 DNA Analysis lab we learned about the amazing structure of DNA. We learned how all DNA molecules are made up of Adenine, Thymine, and Guanine, as well phosphates. Before this lab I knew about the different names for the parts of the DNA, and which ones paired up, I but never fully understood why the structure is a spiral. After building our own 3d model I have a much better understanding of how it is linked together. We also sketched the structure in our lab books with colors to represent the types of elements, which was helpful in learning about the structure.

5. Design a Controlled Experiment 1.1.5 Time of Death
In the Time of Death lab activity we used logger pro software to simulate how the body loses heat after death. This is known as algor mortis. Before doing this activity I had no idea how crime scene investigators determined a time of death. Now I know, and by recording the change in temperature after a set amount of time, we were able to determine the time of Anna's death. This is very useful in forensic science in order to determine the time of death at a crime scene.This artifact meets the criteria of the objective because we had to create our own experimental design including: a hypothesis, procedure, conclusion, summary, and we also determined the independent and dependent variables. |
Quarter #3
Objective #1: Recognize how the Nucleotide sequence in the dna
determines the amino acids in a protein
1. EXAMPLE #1: 3.2.2 THE GENETIC CODE
In The Genetic Code lab, we learned about how mutations works and the effects they can have with the resulting code. In the beginning of the lab we decoded a message and simulated a substitution/point mutation by changing one nucleotide. We found that it changes the message by one letter overall. Later when we deleted a letter of DNA code, which simulated a frame-shift mutation, we found out that the message was completely scrambled. This lab activity helped us to learn how the nucleotide sequence of the DNA is very important in determining the amino acids which make up a protein. Also changing just a single letter can cause major problem in the DNA code.
2. EXAMPLE #2: 3.2.3 Does changing one nucleotide make a big difference?
In the Does Changing One Nucleotide Make A Big Difference? lab activity we learned about some the devastating effects mutations can have. In the activity we learned about how in sickle cell disease a single point mutation can cause serious changes to the red blood cells. By replacing glutamic acid with valine the overall blood cell looses it shape and becomes sickled because of the hydrophobic amino acids. Clumping also occurs as well which is a big problem in sickle cell disease. Overall this lab activity meets the learning objective as it shows how important the DNA sequence is as well as how it determines the amino acids of protein.
3. EXAMPLE #3: 3.3.1 Concept MAp assignment
In the concept map assignment, we learned about the relationships between the different terms and aspects of DNA. Before doing this activity most of vocabulary words sounded almost identical to me. Like DNA, Genotypes, Phenotypes... Now I fully understand how they each relate to each other and also their meanings. This activity helped me understand how the DNA nucleotides code for the amino acids and proteins which fits the objective.
objective #2: Identify the main structures of the heart
and describe their functions
4. EXAMPLE #1: 4.1.1 Path of Blood in the heart
In the Path of Blood in the Heart lab we learned about the flow of blood throughout the heart. Before doing this activity and the diagram with the strings in class I had no grasp of how the flow actually goes. Now I can name the veins, valves, and arteries as well as which parts of the heart are oxygenated vs deoxygenated. We created our very own heart box drawings of the heart, which helped reinforce the concept of blood flow. Overall, I think this activity definitely fulfills the objective of understanding the heart's structure and helped me greatly.
5. EXAMPLE #2: 4.1.2 Anatomy of the heart
In the Anatomy of the Heart lab we dug deep into the meat of the different parts of the heart. I mean literally too, as we dissected a sheep heart. In the lab we made observations about the size, shape, and characteristics of the veins/arteries as well as how the valves in the heart work. This lab was a great way to learn about the different structures of the heart along with their functions. We labeled the different parts with toothpick flags as we dissected the heart in order to help identify each part. Dissecting a heart with the hands-on learning experience was really beneficial for me and also helps meet the objective as I now understand the different parts of the heart along with their functions.
Quarter #3
Objective#1 : Recognize that cholesterol is transported in the blood by protein complexes called:
high density lipoprotein (HDL) and low density lipoprotein (LDL).
4.3.1 What is cholesterol?
In the activity 4.3.1 What is Cholesterol? we researched more about cholesterol and then created a brochure that informs people more about it. Before this activity I never knew that there is a Bad cholesterol and Good cholesterol. LDL transports to the cells where plaque builds up. HDL transports to the liver, where it's processed. Also, I didn't realize that cholesterol is an important part of many functions in the body, such as cell membranes, learning/memory, synthesizing bile for digestion, vitamin D, and steroid hormones. I always thought that cholesterol was only a bad thing because it's known for clogging up blood vessels, so it was interesting to learn more about how cholesterol is actually beneficial to the body.
