METABOLISM(4.1)
The process that breaks down food to release energy for the body is called
Metabolism
What sport does Jordan Jones compete in?
Cyclist
What do scientists use to decide which claim is best supported?
Evidence and reasoning
What is a Science Seminar?
A discussion where students use evidence to support or challenge scientific ideas.
What happens when glucose and oxygen react in the body?
They produce energy through cellular respiration.
What two molecules combine in cellular respiration to create energy?
Glucose and Oxygen
What question were scientists trying to answer about Jordan Jones?
How Jordan improved his performance and increased his cellular respiration.
What type of red blood cell pattern shows a natural change instead of blood doping?
A steady or gradual increase in red blood cells
What is one rule students must follow during the Science Seminar?
Listen, respond respectfully, and use evidence to explain their thinking.
Why do athletes train at high altitudes?
To help their bodies make more red blood cells and use oxygen more efficiently.
What system brings oxygen into the body for energy release?
The Respiratory System
Name the 3 possible claim scientists made about Jordan Performance?
Blood doping, high-altitude training, or changing his diet
Why is consistent data important when evaluating a claim?
Because consistent data makes the evidence more reliable and supports scientific reasoning.
What is the purpose of using argument organizers in the Science Seminar?
To organize evidence under the correct claim.
What effect does high-altitude training have on metabolism?
It improves oxygen use and energy release during activity.
What system delivers glucose and oxygen to the cells?
The Circulatory System
What evidence showed that Jordan’s red blood cell count increased steadily over time?
His data showed a gradual rise from 4.6 to 5.1 million red blood cells per microliter.
What did scientists notice about the age of Jordan’s red blood cells?
They were all the same age, meaning no artificial blood was added.
Which claim did most scientists agree was the strongest by the end of the seminar?
Claim 3 – Jordan improved due to high-altitude training.
What did scientists notice about Jordan’s oxygen efficiency during training?
It increased by about 12%, helping his muscles perform better.
Why is oxygen important for cellular respiration?
Because oxygen helps break down glucose to release energy for muscles and body functions.
Why did the scientists decide diet was not the reason for Jordan’s performance?
Because his food logs and glucose intake stayed the same.
How does reasoning connect evidence to scientific ideas?
Reasoning explains how the data supports or disproves a claim using scientific logic.
Why was Claim 3 stronger than the others?
It had consistent data, scientific reasoning, and matched how the body naturally adapts to altitude.
How does cellular respiration help athletes perform at a higher level?
It allows their cells to release more energy for endurance and strength during physical activity.
