Swimming Problem Maths Investigation
Introduction
============
A group of swimmers are following a training schedule that requires
them to dive into the water and swim one length of the swimming pool.
They must keep doing this until they have completed 20 lengths. For
safety's sake they have been allocated a single lane of the pool and
all the swimmers must swim in the same direction in single file.
Half of the swimmers say that it will be quickest always to swim in
the same direction, climbing out of the pool at the end of each length
to rejoin the queue. The other swimmers want to climb out of the pool
at the end of each length, wait until all the simmers have completed
the length and then swim back one by one in the opposite direction.
I have to pick the method that I prefer and I have chosen the one
where they get out at the end of each length, wait until all the
swimmers have completed the length and then swim back in the opposite
direction. I have chose this way because then the swimmers don't have
to waste their energy walking from one side of the pool to the other
all the time and they can use their energy to swim.
To set up a model for this experiment first of all I have to make a
few assumptions.
First of all I have to think of a set distance for the length of the
pool. Because this is a variable it will make a difference in the time
that it takes to do one length of the pool.
I also have to assume that all the swimmers are swimming at the same
speed and at a constant speed all of the time.
Each person has to dive in the pool so many seconds after the last
one, this I obviously or safety so people do not dive onto each other.
I will set up an appropriate model keeping in mind the assumptions
that I have made.
to get an idea of how I would do my real experiment and what apparatus
For this experiment, you will add the measured amount of the first sample to the measured amount of the second sample into its respectively labeled test tube then observe if a reaction occurs. In your Data Table, record the samples added to each test tube, describe the reaction observed, if any, and whether or not a chemical reaction took place.
the mass and initial temperature of the water. Next, impale the food sample on the needle. Next, light
The novel Swimming in the Monsoon Sea by Shyam Selvadurai is about the journey of living and reveals that life is not fair not to mention, it will always continue to advance with no pauses regardless of the situation.
The input variable which will be used in this investigation will be the light intensity (this will be a 100Watt bulb being moved closer and further away from the plant). The outcome variable which will change as a result of this experiment will be the amount of oxygen made in the experiment due to the amount of light intensity increases (causing the plant to photosynthesise more).
I am going to carry out an experiment to measure the change in mass of
Then take the ruler and put it on the end of the opisthocranion and measure the distance in cm,record your answer on the table
Many people around the world have experienced a loss of family due to tragic wars. In A Long Walk to Water, written by Linda Sue Park she shows how Salva loses his family and friends and is depressed from the tragic war that threatens his survival in Southern Sudan. The factors that made survival possible for Salva was his persistence and determination, his ability to preserve food, and show caution in dangerous situations.
Our project is how to train goldfish. We want to test the behavior of the fish. In the other we will just feed them. The constants are the tank, the amount of the goldfish, the feeding time, the rocks, and the days we clean the tank. In the experimental group we will have two fish and every time we feed them we will have two fish and every time we feed them we will ring a bell for 7-seconds. In the control group, we just feed the fish. We will condition the fish who know when they are being feed. In conclusion, our science fair project is
Fear is an emotion which everybody has. Fear can be rational and irrational. Fear is an emotional response which arises from the impression of danger and sometimes it can save us from getting hurt. But if a person fears too much then the fear can stop us from doing the things we want to do. One has to conquer ones fear and once it is conquered the feeling of fear can be replaced by happiness. This theme is described in S.J. Butler’s short story “The Swimmer” from 2011. Butler writes about a woman who wants to swim in the river but she is too afraid to do that. She looks everyday at the river and one day she overcome her fear and swims in the river. This helps her to change.
If I am to use a square of side length 10cm, then I can calculate the
the graph I should be able to read off what length is needed to create
There is not really that much I can do to help make this experiment a
I learn swimming at the age of 23 I remember going in the water for the first time it was in one of the beaches in NH I cannot remember really well. My husband and his family just assume I knew how to swim. Most especially coming from a warm continent. I have been to the beach before, but we do not get into the water, it much more for hanging out and dating spot dressed in sun dresses while the wind blow your skirt left and right not getting wet. I remember my husband and I got in the water and his parent were in the water as well, I was just standing everyone were swimming I was asked to join and swim under the water I looked at them as if they were crazy. I told my husband I could not swim, he said you don’t have to really swim, we are just here to cool
