SC Standards Standard 7.L.3: The student will demonstrate an understanding of how the levels of
organization within organisms support the essential functions of life. 7.L.3B Conceptual Understanding: Multicellular organisms (including humans) are complex
systems with specialized cells that perform specific functions. Organs and organ systems are composed of cells that function to serve the needs of cells which in turn serve the needs of the organism.
7.L.3B.2: Construct explanations for how systems in the human body (including circulatory, respiratory, digestive, excretory, nervous, and musculoskeletal systems) work together to support the essential life functions of the body.
o S.1A.6: Construct explanations of phenomena using (1) primary or secondary scientific evidence and models, (2) conclusions from scientific investigations, (3) predictions based on observations and measurements, or (4) data communicated in graphs, tables, or diagrams
Essential Learning Experiences: 1. It is essential that students construct explanations for how systems in the human body
(including circulatory, respiratory, digestive, excretory, nervous, and musculoskeletal systems) work together to support the essential life functions of the body.

2. It is essential for the student to be able to understand the basic form and function of each of the following body systems as well as the interrelationships that occur between systems to ensure the survival of the organism.

Week 1 Lab Reaction Times:
Name(s): _______________________________________________________
Part 1: Read the following narrative and answer the questions
Narrator: Fouad and his brother Abdul were playing a game of “hand slap”. Fouad seems to win more games than Abdul.
Fouad and Abdul sit opposite each other playing and slaps
Fouad: I have such a good jump on you, Abdul!!! I know when you are going to move your hands before you do yourself. I have excellent reaction time.”
Abdul: Well, maybe you do win more than I do, but I think I have really good reaction time too.
Fouad: Well, you sure don’t show it in the game. If you can’t win at hand slaps, why do you think you have good reaction time?
Abdul: Because I am quick at other games. You only beat me at this one!
Fouad: I saw something in a magazine that will help us to decide who is faster. Do you wanna give it a try?
Abdul: Sure as long as it’s fair. What is the test?
Fouad: You have to get a meter stick first. One person holds it at the top and the other person opens his first finger and thumb apart at the bottom of the stick. The person who is holding the stick lets it go and the other person pinches his fingers together as soon as he notices the stick falling to try to stop it. How far down the stick travels measurers how fast the other person reacted? The less the stick falls, the quicker you grab it and the better your reaction time.
Abdul: That sounds cool!!! I think I can think of all kinds of reaction times we can measure with the test. Let’s get a meterstick and do it!!! But remember we have to make sure it’s a fair.
Fouad: Okay, we’ll make sure it’s fair but what do you mean by different kinds of reaction time?
Abdul: You’ll see. Maybe you won’t be the best at all of the different kinds.
1) What do you think will happen when you drop the ruler? Which partner do you think will have the fastest reaction time?__________________________________________________________________________________
__________________________________________________________________________________
__________________________________________________________________________________

2) Do you think that there would be a test that would better test reflexes? What would the test look like?__________________________________________________________________________________
__________________________________________________________________________________
__________________________________________________________________________________
______________________________________________________________________________
Part 2: The Science behind the test. Read the following passage and answer the questions.
The experiment tests how long it takes the brain to translate visual information (falling ruler) into your voluntary (or conscious) motor commands and actions (grasping finger movements) that lead to the ruler being caught.
15
The shorter the time, the faster your reactions.…. that’s if you were paying attention in the first place! Indeed, practice specifically affects the ‘associative centres’ in the brain, so that you can respond faster to what’s happening in your visual world. The flow of information along the ‘visual’ and ‘motor’ nerve pathways is relatively constant even with lots of practice. It all comes down to ‘attention’ or ‘…being on the ball!’
Part 3: Doing the test.
INSTRUCTIONS
i) Get a 30cm ruler…
ii) One person holds the ruler near the 30cm mark and lets it hang vertically…
iii) The other person places their thumb and index finger either side of the 0cm mark ready to catch it when it falls - their fingers shouldn’t touch the ruler.
iv) Without warning the person holding the ruler lets go and the subject tries to catch the ruler as soon as possible.[Hint: To prevent guessing, vary the time before letting go of the ruler].
v) The level (in cm) just above the subject’s first finger where the ruler was caught is recorded.
vi) The same person is tested 5 times and then calculate the mean average of their results (add all five numbers together and then divide by five).
viii) Now swap over and test your partner.

Remember… Milliseconds are one thousandth of a second. This means that:One second (s) = 1000 milliseconds (ms)Half of a second (0.5s) = 500 msA quarter of a second (0.25s) = 250 msOne tenth of a second (0.1s) = 100 ms
Reaction time chartTake you reading from Chart 2 and figure out what the reaction times are for each person in the group. (Chart 3)

1) So what does your reaction time mean – are you fast enough for an F-16? Why would or why would you not be fast enough to fly an F-16?___________________________________________________________________________

__________________________________________________________________________________
Part 6: Time to Experiment
After you’ve tested yourself, why not experiment further. Here’s a few suggestions, do reaction times vary:
for people of different ages (children versus adults)? if you use your dominant hand versus non-dominant hand? if you are tired or alert? for men or women? depending on your mood? after an alcoholic drink?
Part 7: Answers generally, the older you are the longer your reaction time (that ruler keeps hitting my foot!) as you might expect, the dominant hand has a faster reaction time. in ‘Catch the ruler’, it helps to pay attention – so being alert is a great asset. who is faster ‘men or women’? …you tell me? mood affects attention and therefore reaction times. alcohol greatly increases reaction times.
19
A final thought: Can you imagine doing several tasks together, each requiring fast reaction times with high precision, whilst at the same time concentrating on steering a jet plane - for example as part of an aerobatic team at the Paris air show?
A lot to contend with, without 9g on top: The F-16 flight controls. Image: Lockheed Martin

Chicken Wing DissectionInstructions
FOLLOW THESE DIRECTIONS CAREFULLY, DO NOT SKIP STEPS!
FIRST DISSECTOR: ____________________
1. Use your fingers to peel the skin away from the muscle near the upper wing.
2. Now, using the tweezers and razor, carefully remove all of the skin except the skin on the wing tip. Be careful not to cut the tendons or ligament.
3. Carefully examine the muscles and make observations in the space provided. (Write response to Lab Question #1 and 2)
4. Gently try to pull a muscle from the bone. Does it come off? Try to find out why. (Write response to Lab Question #3 and 4)STOP AND SWITCH ROLES. NEW DISSECTOR: ____________________
5. Find the biceps and use your fingers to gently pull the bicep. Look at how the wing moves. Now, find the triceps and use your fingers to gently pull on the triceps. Take turns pulling back and forth on the bicep and tricep muscles and observe the movement that happens when a specific muscle is pulled.
