Worksheet Overview

QUESTION 1 of 10

Edplace know you love carrying out investigations! 

 

Whatever your feelings about science, you're a naturally curious human being and, therefore, an investigator. It might be trying out a new food you've never tried (taste investigation), trying out a new movie at the cinema (entertainment investigation) or even seeing whether eating blueberries really does turn your tongue blue (chemical staining investigation)!

 

Child tongue

 

If we take it as a given that you love investigating things, when it comes to doing an actual investigation, one of the vital aspects of it is writing the report on what discoveries you have made

After all, a great deal of thought and effort has gone into it and it's really important to tell the world what you've found out. This is how new important information is spread around, from how to make a screen touch-sensitive to how to make truly holographic TV, from how to grow plants on Mars to how to grow a steak in the lab!

 

Report questions

 

You begin any investigation with an idea you what you want to test, your prediction and a hypothesis.

Then you planned how you were actually going to try to find out the answer. You then end up with lots of data which needs to be sorted out to see whether it led you to the answer to your original question. Then, of course, lots of other ideas popped into your head along the way: "That won't work because ...", "It would have worked better if I'd ...", "Perhaps next time I could try ..." and so on. Ideas for improvement and further work all goes into your report.

 

So, let's have a look at what your report on your investigation should look like. We're going to join Willow and Zara who are trying to find out whether their ideas about how sensitive our skin is are correct, according to where on our bodies we're being poked!

 

Boy surprised

 

Zara and Willow had been playing and found out that when they tried to use their electronic tablets using the backs of their fingers, it was really hard to control how the screen behaved. 

 

Zara said that she reckoned our fingertips are much more sensitive than the backs of our hands.

The girls decided that a good way to test how sensitive their skin is in different places on the body would be to push gently with a certain number of fingers. 

 

Then the subject (the girl being tested) would call out how many fingers she thought were pressing on her skin (with eyes closed!).

 

They decided on six areas of the body to test and that each area would be tested five times.

 

This part of their investigation is called the ...

Prediction

Plan

Conclusion

Results

In their report, they decided to record how many fingers were pressed on to the skin each time and then, what the subject (the girl being tested) said she thought she could feel being pressed into her skin.

 

 

Finger pressing on hand

 

 

Which of the following would be the best way of displaying their data?

A bar chart.

A pie chart.

A scatter graph.

A table of results.

When the two friends carried out their experiment, they found that the fingertip always correctly identified how many fingers were touching it, but that the sole of the foot (the bottom of the foot) was right only 20% of the time.

 

Willow then stated that the sole of the foot is not very sensitive.

A bar chart.

A pie chart.

A scatter graph.

A table of results.

From the data, they collected the young scientists were able to draw up a list of the results for each part of the body, according to how accurately each area of their skin correctly identified how many fingers were pressing on it. 

 

They did this using percentage success rate (so, 100% = got it right every time, 50% = got it right half the time, etc.).

 

Using their results, match each area of the body with how sensitive it is (best = 1 to worst = 6).

Column A

Column B

Fingertips = 100%
4
Sole of foot = 20%
2
Back of hand = 60%
6
Back of neck = 30%
1
Cheek = 80%
5
Elbow = 50%
3

When they wrote up the report on their findings, Zara made a conclusion from the data they had collected.

 

Using their results chart (below) fill in the three parts of the body that she mentions.

 

PART OF BODY TESTED PERCENTAGE OF CORRECT IDENTIFICATIONS
FINGERTIP 100
SOLE OF FOOT 20
BACK OF HAND 60
BACK OF NECK 30
CHEEK 80
ELBOW 50

Column B

Fingertips = 100%

The two young scientists decided that using finger pushes, with different numbers of fingers, was not a very reliable method of testing the sensitivity of the skin.

 

They suggested that using something pointed like a small pin, and pressing it gently until the subject called out, might give better results.

 

A pin could easily be pressed too hard and might hurt the subject being tested. 

 

Which one of the following might be a better choice?

A needle.

A brush bristle.

A metal wire.

A strand of human hair.

A Pencil.

Our skin is made of several layers and performs many tasks for us. 

 

What type of body structure is the skin?

 

Skin

Cell

Tissue

Organ

Organelle

The skin has lots of jobs to do.

 

Match the function (job) with the description of what the skin is doing for us.

Column A

Column B

Protection
Blocks microbes from entering the body.
Sensitivity
Sweating or perspiration.
Movement
Skin is elastic or stretchy.
Temperature control
Has touch detectors.
Good health
Makes vitamin D.

Final question - you have to make an estimate (a vital skill for a scientist!). 

 

You don't know the answer, so make an educated guess (= estimate).

 

What is the approximate area covered by the skin of an adult human being?

  • Question 1

Zara and Willow had been playing and found out that when they tried to use their electronic tablets using the backs of their fingers, it was really hard to control how the screen behaved. 

 

Zara said that she reckoned our fingertips are much more sensitive than the backs of our hands.

CORRECT ANSWER
EDDIE SAYS
So, what did Zara say? "I reckon our fingertips are much more sensitive than the backs of our hands." That's her hypothesis. It's what a statement she has made which she must verify as either true or false. So, what's a prediction then? That's a specific outcome in their experiment: "I predict that my fingertip will get the test correct every time." Got that?
  • Question 2

The girls decided that a good way to test how sensitive their skin is in different places on the body would be to push gently with a certain number of fingers. 

 

Then the subject (the girl being tested) would call out how many fingers she thought were pressing on her skin (with eyes closed!).

 

They decided on six areas of the body to test and that each area would be tested five times.

 

This part of their investigation is called the ...

CORRECT ANSWER
Plan
EDDIE SAYS
At this point, Zara and Willow have a plan of what they intend to do in order to find out the answer to their question. Their plan may have to change, if they find it doesn't work, but it's the plan they start with.
  • Question 3

In their report, they decided to record how many fingers were pressed on to the skin each time and then, what the subject (the girl being tested) said she thought she could feel being pressed into her skin.

 

 

Finger pressing on hand

 

 

Which of the following would be the best way of displaying their data?

CORRECT ANSWER
A table of results.
EDDIE SAYS
The girls are going to record data about where the fingers were pressed, how many fingers were used and the subject's reaction. The best way of setting that out is in a table of results. Later on, the girls may choose to display their findings in a different way, but at this point, a table is best.
  • Question 4

When the two friends carried out their experiment, they found that the fingertip always correctly identified how many fingers were touching it, but that the sole of the foot (the bottom of the foot) was right only 20% of the time.

 

Willow then stated that the sole of the foot is not very sensitive.

CORRECT ANSWER
EDDIE SAYS
Willow saw that the sole of the foot only got the correct answer 20% of the time and from this drew the conclusion that it's not a very sensitive area of the skin. She based that conclusion on the data that they had gathered.
  • Question 5

From the data, they collected the young scientists were able to draw up a list of the results for each part of the body, according to how accurately each area of their skin correctly identified how many fingers were pressing on it. 

 

They did this using percentage success rate (so, 100% = got it right every time, 50% = got it right half the time, etc.).

 

Using their results, match each area of the body with how sensitive it is (best = 1 to worst = 6).

CORRECT ANSWER

Column A

Column B

Fingertips = 100%
1
Sole of foot = 20%
6
Back of hand = 60%
3
Back of neck = 30%
5
Cheek = 80%
2
Elbow = 50%
4
EDDIE SAYS
How did you get on? It's a question of getting those percentages into order. So, 100% identification is best, then 80%, 60%, 50%, 30% and the sole of the foot at 20% correct identification is the worst or least sensitive area of the body tested.
  • Question 6

When they wrote up the report on their findings, Zara made a conclusion from the data they had collected.

 

Using their results chart (below) fill in the three parts of the body that she mentions.

 

PART OF BODY TESTED PERCENTAGE OF CORRECT IDENTIFICATIONS
FINGERTIP 100
SOLE OF FOOT 20
BACK OF HAND 60
BACK OF NECK 30
CHEEK 80
ELBOW 50

 

 

 

CORRECT ANSWER
EDDIE SAYS
You can see that Zara has used the data they collected when she made her conclusions. Were you able to follow her reasoning? The fingertip was the most sensitive (100% correct), the sole of the foot was the least sensitive (only 20% correct), while the elbow (50%) got the answer correct half the time. Make sense?
  • Question 7

The two young scientists decided that using finger pushes, with different numbers of fingers, was not a very reliable method of testing the sensitivity of the skin.

 

They suggested that using something pointed like a small pin, and pressing it gently until the subject called out, might give better results.

 

A pin could easily be pressed too hard and might hurt the subject being tested. 

 

Which one of the following might be a better choice?

CORRECT ANSWER
A brush bristle.
EDDIE SAYS
Needle? That's worse than a pin! A metal wire might be too sharp as well, and possibly the pencil point. A strand of human hair would be very hard to sense and even harder to pick up! In fact, a brush bristle is perfect: fine enough to impact a small area, but not so sharp that it's going to hurt.
  • Question 8

Our skin is made of several layers and performs many tasks for us. 

 

What type of body structure is the skin?

 

Skin

CORRECT ANSWER
Organ
EDDIE SAYS
In fact, just like muscles, eyes, heart, lungs and so on, our skin is an organ. It's made up of different tissues that you'll learn about in the next stage of your biology course.
  • Question 9

The skin has lots of jobs to do.

 

Match the function (job) with the description of what the skin is doing for us.

CORRECT ANSWER

Column A

Column B

Protection
Blocks microbes from entering the...
Sensitivity
Has touch detectors.
Movement
Skin is elastic or stretchy.
Temperature control
Sweating or perspiration.
Good health
Makes vitamin D.
EDDIE SAYS
Isn't skin amazing? I mean, it's just skin, and yet it does amazing things for us. It's our first line of defence - it prevents most of the nasties from getting into our body - it helps to keep us cool, it allows us to move easily, it's as sensitive as it needs to be - it's incredible!
  • Question 10

Final question - you have to make an estimate (a vital skill for a scientist!). 

 

You don't know the answer, so make an educated guess (= estimate).

 

What is the approximate area covered by the skin of an adult human being?

CORRECT ANSWER
2 m2
EDDIE SAYS
Well, did you just guess? If so, let's have a look at a better way. One way is to picture 1m. A tall man is about 2m tall. At the most 1m wide, so 2m2 isn't far off, is it? Don't forget, skin covers us right around. If we think mathematically, maybe you thought 2000cm2 was a good shout. Well, a flat human being 45cm tall and 45 cm wide would fit that. Remember, there are 100cm in 1m, so 2m2 is actually 200cm x 100cm (or 20,000cm2!).
