Go over the first example with students.
Have students fill out the claims chart. This activity can be done individually, in small groups, or collectively as a class.
If students are struggling, remind them that in science, a claim must be backed up by evidence.
Give students a chance to discuss the reasoning behind their selections. This discussion can take place in small groups or as a whole class.
Students may struggle to determine what is or isn’t evidence.
Evidence in science may come from:
- Interactions with the world around you. For example: Seeing a black dog gives evidence that not all dogs are brown.
- Data you collect yourself. For example: Measuring how high different dogs can jump.
- Data collected by other people. For example a company does a study to determine how fast a skateboarder can go.
Statements such as something is “the best,” “better,” or “more important” are not good claims.
