Scientific Models Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What is a scientific model?

A scientific model is a simple way of showing or describing how something works.

Why do scientists use models when studying things that are very small or very large?

They use models so they can see, think about and explain things they cannot watch directly.

Give one example of a diagram used as a model in biology.

A labelled drawing of an animal or plant cell is a diagram model in biology.

Give one example of a physical model used in science.

A plastic model of a human skeleton is a physical model used in science.

What is a computer model in science?

A computer model is a program that copies how a real system might behave.

How can a model of a cell help students or scientists?

It shows the main parts of the cell and helps people see how they fit together.

What does it mean when we say a model represents something?

It means the model stands for a real thing or idea and shows what it is like.

Why are scientific models often simpler than the real thing?

They are simpler so that only the most important parts are shown and are easier to understand.

How can scientific models help scientists make predictions?

Scientists can change parts of a model to see what might happen in real life.

How is the lock and key idea for enzymes an example of a model?

It uses simple shapes to show that only one kind of substrate will fit into an enzyme.
