Explaining Cellular Respiration

Scientists construct explanations from observed patterns in the world and look for how patterns are similar or different in a variety of environments and settings. As scientists validate patterns and other pieces of evidence, they develop scientific theories.

Scientific explanations link theories of how the world works with pieces of evidence from observations and investigations. Scientific explanations can also change over time. As new pieces of evidence are validated, they are applied to scientific theories. Sometimes these theories are modified or overturned entirely.

Scientific explanations contain three elements: a scientific claim, evidence to support the claim, and reasoning that connects the evidence to the claim.

At the beginning of this concept, you were presented with a question. You were asked to answer the question as best you could. Since then, in the course of investigating the lesson questions, you have collected a wide variety of evidence. This evidence may have come from text, video, or virtual and laboratory investigations. Now apply this evidence to the Explain question:

Explain Question

How is food converted into the energy needed to move these athletes?

Your answer to this question will become the claim for your scientific explanation. There are many different ways that scientists communicate scientific explanations—through models, diagrams, data charts, graphs, written text, and oral presentations.

Your teacher wants you to resubmit.

While analyzing the evidence you collected to support your claim, select an appropriate method for communicating your scientific explanation. Remember, no matter which communication format you choose, it is important to use the correct scientific language to describe your evidence.

Represent your scientific explanation using a model (physical or diagram). Attach an image or a video demonstrating your model.
Use an oral communication method, such as a video of yourself, a conversation with another student, or a skit. Attach a video of your scientific explanation.
Present your scientific explanation in a creative written form using Board Builder.
Write your scientific explanation in the space below.
Be sure to include a concluding statement.
