What Questions do you still have?

​

​

​

​

​

​

​

What do you think?

​

Think about it for awhile and share your ideas with your classmates.

​

Question: Is there only one way to classify objects or can you classify objects in more than one way?

Idea 1 - The "many ways" Idea

Idea 2 - The "One way" Idea

Which Idea do you think is right?

Or do you have your own idea?

Talk to your classmates about what you know right now.

​

Listen to other ideas and think about how they might work or not work.

Now it is time to write down your thoughts

• It is fine if you are not sure right now.
• It will require more work to learn the right answer.
• Just think about what you know and be open to learning more
• Write down your ideas in your thinking log.

​

​

It’s time to do some research!

• Scientists sometimes get things wrong.

​

• When scientists get things wrong it isn’t because they are trying to fool people or tell them bad information. Scientist change their ideas when better evidence becomes available.

​

• A person who continues to support an idea when the new evidence tells them the idea is wrong is not thinking like a scientist.

Hello, my name is Tyler Davin-Moore andI am a firefighter in Chico, California.

• Before I started fighting fires I studied science and had the best grades in my class.
• I always check with other scientists to make sure the things I believe match what other scientists have found in their research.
• I really liked learning about ways to classify objects by their properties and won a big award when I was in college. I made this document for you and I hope it helps you learn.

Now it is time to re-think about what we know.

• It is fine to change your mind.
• If your original idea was wrong, but you learned something new by finding better evidence you are acting like a scientist!
• Even if your original idea was right you need to explain why.
• Write down your ideas in your thinking log.

​

It’s time to do some research!

• Although no single universal step-by-step scientific method captures the complexity of doing science, a number of shared values and perspectives characterize a scientific approach to understanding nature.
• Among these are a demand for reasonable claims supported by evidence that can be measured and tested repeatedly.
• When a new idea starts to gain evidence the old idea must be tested against the new idea to see which one has stronger evidence.

Article 1

​

Hello, my name is Dr. Jennifer Fedario. I am a scientist who studies how matter changes.

• I study with other scientists from all over the world and our work has helped people build new machines.
• My team of scientists won an award for the article we wrote about solids, liquids, and gases last year!
• I wrote this short article to help you learn about how objects can change and change back! I hope it helps!

​

​

Now it is time to re-think about what we know and write down our ideas.

• It is fine to change your mind.
• If your original idea was wrong, but you learned something new by finding better evidence you are acting like a scientist!
• Even if your original idea was right you need to explain why.
• Write down your ideas in your thinking log.
