Smell and taste
We did an experiment using jelly beans where we were blindfolded and had to guess the colour based on smell and taste. Here is some of our thinking about that experiment.
Is it easier to recognise the jellybean by smell or taste?
7 people got them all correct for smell and taste
8 people found it easier to recognise by smell
2 person found it easier to recognise by taste
1 person got the same in smell and taste
We can conclude that we know our jelly beans quite well! We think that overall it is easier to recognise jelly bean's flavour/colour by its smell.
How can sight impact taste?
Sam looked at the yellow jelly bean and smelled it and thought it would taste like banana. Our brain can think that yellow means banana so that is what we taste (it is actually pineapple). The mind can play tricks on you.
Touch
We then had to use callipers to touch using either one point or two points on different body parts. The callipers were set at different widths. We had to do each spot 3 times with one point and 3 times with two points. Here is some of our thinking about touch.
Why do we need to do each spot 3 times?
If you only had one turn you wouldn't get as much data. We might get more accurate results.
Which parts of the body are most sensitive?
Cheek
Inner arm
Palm of hand
Sole of foot
What evidence have you used to judge this?
Because Aviah said 'ow' a lot
Because William could feel it hard although Ruben put it on lightly
There were the most ticks which means your body can feel the points more
What advantages might there be for these areas to be sensitive to touch?
We use our palms to feel things. Our feet should be sensitive so we can feel if there is something down beneath us. Hands and feet are the parts of our body that will touch things first so it keeps us safe.
There were also some scent bottles that we had to match up and recognise different smells and some optical illusions to explore.
