    * Andrei, Chad
    * Younger kids would be more willing to help compared to people who are the same age as the person who asked.
    *1. Ask for help to a student in school who is younger than the person who is asking for a favor.
    2 Ask for a simple help, for example passing a notebook to another person in another place.
    3. Ask for same help to a student in school who has the same age as the person who is asking for a favor.
    4. Record how each kind of age group reacted differently.
    *School, lunch time
    *Notebook (to ask for a favor)
    *10 times for each age group
    *Potential variables would be if other student in the same age group witness the same person asking for same favor at a same place at the same time for several different times.

    Hypothesis: People does show the evidence of bidirectional memory by picking out the picture behind the curtain.
    Description: there will be two curtains run by computer, and a picture of a hot girl will be behind one of those two curtains, , when they click the curtain, the curtain will open up and the picture will appear. The participants will be wanting to choose the the picture so if they have the bi-direction of memory in their subconscious, they would choose the right one.
    Sampling Participants: There will be 50 participants of both male and female. If they do not feel comfortable seeing or not willing to see the picture, they will not be selected for this experiment. Focus group sampling of people that are older than 17 years old, wanting to see pictures of hot girls/guys (human nature), and willing to participate. Most of the participants will be among people that I know personally, and some will be from random sampling (who ever I run into on streets) to avoid some sampling bias.
    I will carry out the experiment starting today until sunday
    Computer with ppt
    One participant will take about 2 minutes, so the entire experiment will take about two hours maximum.
    The potential variables are if the participant (individual) isn’t in the room where the experiment occurs, participant might be influences by others for reasons like fear of judgements. There is no way of avoiding bias when sampling, there will be something unnoticeable in common between all of the participants because I somehow fond them and they agree to do this experiment.

    We are going to conduct an experiment about the motivation “money”. We will have a member of our team to purposely drop money in front of a random subject on the street. We will ensure that the subject would notice the dropped money and we will observe the response of the subject. The subject would either notice the money and give it back to the dropper or take the money away. The experiment will be repeated to different people with different values of money and at different time. We can then analyze the results we collect and decide whether most people would be more motivated by money or by ethics.

    1. What is your hypothesis
    People’s response will vary according to the amount of money. Our hypothesis is that the higher the value of money we drop, the more likely people will take the money away

    When we drop money: People will:
    With a high value Take the money away
    With a low value Return it to the dropper
    With a very low value Not care

    2. What is your method
    1. Prepare money with different values (1, 5, 10, 50, 100 RMB)
    2. Find a place with people walking
    3. Have one member of the group drop money in front of a stranger (the subject)
    4. Observe and record the response of the stranger, see whether the subject return the money or not
    5. Repeat step 2~4 for 5 times for each different value of money

    On the day of the experiment, we will divide the work as following:
    Name Jobs
    Woosung Money retriever
    Brian Money dropper
    Jun Camera man
    Sophie Field investigator

    3. How will you eliminate variables
    The variables are
    a. Honesty of the subjects
    b. Economic background of the subjects
    c. Noticeability of the dropped money
    d. Location
    e. Time
    We will eliminate these variables by
    • Repetition of the experiment to different subject (eliminate a and b)
    • Put the money at the same place (obvious so that people will notice it easily) (eliminate c)
    • Keep the experiment in same location (eliminate d)
    • Complete the experiment in a very short time (eliminate e)
    4. How will you record your results
    • Record a video of each subject from a distance so the subject will not notice.
    • Record on a notebook the reaction and response of the subjects
    5. How will you repeat the experiment
    • To different subjects with different value of money (5 subjects for one value of money and a total of 5 values, so a total of 25 trials)

    TOK motivation experiment- Will 8th graders be motivated by money?

    Eloyee, Betty, Elizabeth, Becky

    Aim: Our aim for this experiment is to see if young students (8th graders) will be also motivated by money.

    Hypothesis: We think that when we put money as the motivation, they will be more willing to complete the task with better quality.

    1. Choose 6 participants from each BWYA Grade 8, 2 people from each 3 homerooms
    2. In a empty/ silent room give each participants pen and paper
    3. Given the time of 1 minute, we ask the participants to draw a square on a lined paper. (We will tell them the right squares they have to draw)
    4. For the first two trial we conduct the experiment without any rewarding money or recognition
    5. For the third trial we conduct the experiment with the rewarding of recognition
    6. For the 4th trial we conduct the experiment with the rewarding of 100 kuai
    7. After each trial count the squares and organize it in the data

    Becky will give the instruction when the experiment starts
    Betty and Eloyee will count the results for each trial
    Elizabeth will organize the data for every trial
    We will use computer (Microsoft Excel) to organize the data


    1. Write your name and #1 on the top right corners
    2. Draw as many squares as you can with in one minute
    3. Only perfect squares show on the whiteboard / paper count in the numbers
    4. The squares must be in the lines
    6. start when you hear the word “START”
    7. Stop your pens immediately when you hear the word “STOP”

    “Take a two minutes rest”

    8. Repeat the same thing what you just did
    End OF TRIAL 2
    “Take a two minutes rest”

    9. Repeat the same thing what you just did this time we will inform you who drew the most square
    End OF TRIAL 3
    “Take a two minutes rest”

    10. Repeat the same thing what you just did, but this time, we will pay 100 kuai
    for the person who drew the most square

    • Pen
    • Paper
    • 24 papers
    • 100 kuai
    • Stop watch

    • The size of the square
    o We will eliminate this by providing them lined paper, so by intuition the students will know that their square have to fit each line
    o Since this data is comparing individual person, in other words the real data doesn’t need to be related to competing others, this factor doesn’t affect that much
    • Shape
    o Before we conduct the experiment we will tell them how the squares should be drawn correctly, when recording the data, distorted squares will not count
    • Resting time
    o Because students might be tired after every trial, we will provide them 2 minute resting time

    Aim: To test if age motivates people’s sympathy.

    Hypothesis: Young kids would receive more help than the teenage. Tina’s young sister would seem more helpless to the adults therefore could raise more sympathy than the teenager. Thus we hypothesise that the adults are more likely to help the younger sister than the teenager.

    The chosen female teenager and Tina’s younger sister go to 2 close but separate positions on the street.
    Both start to borrow mobile phones from the strangers on the street with separate excuses.
    If refused, go and find another person and this trail will be considered as failure.
    If granted, the person will make the call and this trail will be considered as success.
    Return to step 2 until 40 trails have been done.
    Compare the results of the female teenager and Tina’s younger sister.

    Where we will be carrying out the experiment:
    Wangjing, around the BWYA campus. The teenager and Tina’s younger sister will be doing the experiment separately on 2 opposite sides of the road. In order to keep Tina’s younger sister safe, Tina and Henry will be watching her at a suitable distance where they can see Tina’s younger sister and not be discovered by the pass-by.

    Necessary equipments:
    As Tina’s sister will call Tina and the teenager will call Soul when they have the phone, Tina and Soul must have the mobile phones and make sure that they are not switched off.

    Necessary trails:
    In an attempt to obtain a fair result, our group is going to do 40 trails for each person and calculate the percentage of success for each of the 2 people.

    In order to keep the trail fair, the teenager that is also going to do the experiment is also going to be female. Therefore we are only going to examine how age differences could bring different sympathy between the adults and not getting concerned with gender problems.

    -People we are asking:
    Different people have different life experiences, we cannot ensure that all the strangers which have been tested on are exactly the same. However in order to minimise this possible influence, the teenager and the young kids are both going to ask 20 males and 20 females. However people are different and that’s why we are doing 40 trails which could observe the general trend among people even they are totally different individuals.

    Topic: Plan for human science experiment

    The aim of this experiment is to observe the actions and behaviour of people when they have an opportunity to take something that is not theirs, therefore to explore the limitation of self-control and human nature under temptations. This experiment will be carried on grade 7 students and grade 10 students.

    If we are experimenting with a higher grade, then the money is more likely to disappear, but if we experiment with a lower grade, then the snacks/candies is more likely to be taken.

    Independent variable
    Year group of the participants The item (money/snack)
    Dependent variable
    Behavior of the participants
    Controlled variable
    Environment of the experiment Using the same items for every experiment Time of the experiment (in the morning)

    Method and Procedure
    1. Get permission from teachers to perform the experiment.
    2. Prepare the materials for the experiment
    3. Prepare the permission slip for student to sign after the experiment
    4. Set up the experiment environment (money and snack left untended in two opposite end of a classroom)
    5. Wait for the participants to enter the environment
    6. Observe the participants
    7. Request the participants to sign the permission slip.
    8. Analyze the data.
    9. Conclusion and evaluation

    Materials and equipment
    ➢ 20 RMB note
    ➢ Candy/sweets (snacks)
    ➢ Available classroom
    ➢ Permission slip for students to sign.
    ➢ Possibly a video camera.

    Study: Observe students’ reactions when saw the bills with different value on the floor.

    People are more likely to pick up bills with higher value and keep it for themselves and ignore the bills with less value. The independent variable will be 3 different values of money (5rmb, 20rmb, 100rmb) and the dependent variable will be the different reactions of the testers (ignore the money, keep the money, look for the owner).

    1. Find a location in school.
    2. Secretly drop a 5rmb bill somewhere noticeable for passer.
    3. Record the reaction of the passer with a camera.
    There are 3 possible reactions:
    1) Ignore the money
    2) Keep the money
    3) Look for the owner
    4. Repeat step 1-4 4 more times.
    5. Repeat step 1-4 for 20rmb bills and 100rmb bills.
    (In total, 12 trials will be completed)

    – 5rmb bill x1
    – 20rmb bill x1
    – 100rmb bill x1
    – Camera (phones with camera are also suitable)

    Recording method:
    Record the data on a table with the right column stating the 3 different values of the bill and the top row stating people’s reaction (take away, ignore, look for owner) for each of the 4 trials

    Anticipated potential variables:
     Location
    The experiment will be tested in one specific location so that one of the variables, location, can be eliminated.
     Number of people around
    This variable can affect the result of the experiment as more people around indicates more responsibility and obligation to behave morally and thus, it is more likely for the participants to ignore the money rather than to pick it up and keep it themselves. The variable can be minimized by testing the trials at the same location and time.
     Location of the money being put
    The money will be put at the same place so that all participants have the same environment for the experiment. Also, the money will be put in place that is very obvious.

    Human Science Experiment in TOK
    Group Member: Mike, Tina Yu, Frank
    Our group has plan a human science experiment to conclude can reward actually motivate people at all. Our hypothesis is that the reward does motivate people when given enough reward that is able to impress people. Our predicted that the group of students with reward, will manage to finish more question than the other group without any reward.
    1. Prepare simple math questions that can be answered without much of knowledge. Example (23+5=?)
    2. Print these questions out on paper and ready for use.
    3. Talk to grade 8 homeroom teacher and use the homeroom time at Friday to do the experiment.
    4. Choose 24 grade 8 students that is willing to do some math question, and evenly distribute these students in to two groups. One with reward, another without any reward.
    5. Tell the group of student with reward, that if they manage to finish x(unknown yet) amount of question, they will be given a pack of chips, or chocolate.
    6. Tell the other group of student that don’t have reward, to try their best to finish x(unknown, but same with the “x” in step 5) amount of question.
    7. Collect the data of students on the amount of question they finish and the amount of student that managed to reach the goal.

    This experiment will happen with the permission of homeroom teachers of grade 8 students, and themselves. The reward will be snacks such as chips or cookie, these reward will be bought by the group.

    1. Money
    2. Chips
    3. 24 paper
    4. Simple grade 1 math questions
    5. Pen
    6. Answer sheet
    7. A place with table and chairs

    – The difficulty of the question been asked to students. These questions will be chosen at a difficulty where even grade 6 can simply solve. Simple math question that don’t need extra knowledge, will help us to put every student at a balanced level.
    – The amount of reward. The reward must be attractive enough to possibly motivate people. For example that probably one piece of candy just can’t motivate people at all. We have to carefully carry out the reward given to the student.
    – The “X” missioned in the method. The amount of question that need to be completed during experiment. It have to be an amount that is not impossible to complete, and not too easy to complete. We have to take deep consideration on this variable.

    Hypothesis: Participants will be more motivated to choose the drawing said to be drawn by the person in front of them over the other “artist” because of the pressure (given with the person standing right in front of them) and hopes to praise that person.


    1. Approach a person
    2. Present the individual with 2 similar drawings (with your own name on one and one of other group members’ name on another)
    3. Tell him/her that you drew one and your friend drew the other one
    4. Ask the individual which of the two paintings he/she believes is better drawn
    5. When the person answers, thank him/her and leave
    6. Note down the results (possibly at the back of the drawings)
    7. Repeat steps 1 to 6 for 39 more times (ideally with each of the four members doing 10 trials)

    Location: school hallways and classrooms


    – 2 drawings (A4 size)
    – a questioner (a person to ask the question)
    – tools to record the results (e.g. pens, pencils, etc.)

    Number of trials: 40 trials in total (10 trials per group member)

    Anticipated potential variables:

    – Gender
    – Age
    – Knowledge in Art
    – Particular taste in drawings
    – Time the participants were asked
    – Preconceptions the participants may have of the people who drew the drawings

    Steps taken to minimize the variables’ impact:

    – Ask both genders in equal proportions
    – Ask various age groups (even teachers)
    – Ask various people/Ask both people taking VA and not taking VA (in DP1-2)
    – Ask all the participants approximately at the same time period (within at most 15 minutes)
    – Give the participants new background information before asking the question

    This experiment can test out the moral in by student. For this experiment, we will create selling zone at lunch time which is when people might have a high possibility to buy our product. Instance of putting a price there, we will let them decide the price.

    Every act of each student will make a change of the conclusion.


    We are expecting a group of people to approach to selling table and took away money or product when the environment around them is empty. however, we also think that most of the people will confuse about the instruction and doing nothing with it too.

    Description of method

    1. buy 5 snacks and 10 drinks.
    2.set up a little selling place,table with all product we buy on it and an instruction to buy.
    3.then we are going to observe several time and calculate the proportion or the percentage.

    4th floor, building B in school.

    1 table, 5 snacks, 10 drinks, 3 pieces of paper, 1 box, 2 markers

    5 day.


    -unclear instruction

    -environment which will effect their act

    The steps to minimise their impact

    If the students notice that there are some people observing them, then they will not do the exact things they want to. We will find time to make sure that few people sees it.

    clear and detail instruction on the table.
