Lesson 6 - Experimental Method

Today, I'm going to...

• know about the steps in planning a scientific experiment,
• be able to provide feedback about the sample investigation, and
• understand why following the steps in planning any investigation helps me make a reasonable conclusion.

Lesson 6 - Experimental Method

• I can complete the planning checklist while evaluating an exemplary sample.
• I can give feedback on the sample investigation by answering the questions.
• I can use several strategies to accomplish the task with my teammates.

Lesson 7 - Solids, Liquids, Gases

Today, I'm going to...

• know about the three states of matter,
• be able to describe the physical properties of solids, liquids, and gases, and
• understand why liquids and gases are fluids.

Lesson 7 - Solids, Liquids, Gases

• I can name the three states of matter.
• I can give examples of the three states of matter that are important to me.
• I can describe the three states of matter and their differences in physical properties.

I am successful if...
