Teacher's field guide

What Students Need to Do: Students collect and combine repeated observations of a natural event. They use that body of evidence to support an explanation and separate observed facts from conclusions.
What Mastery Looks Like: Students can identify which statements are observations and which are explanations. They can cite several observations from a data set and explain how those observations support a conclusion.
Common Misconceptions: Students may treat one observation, a personal opinion, or a prediction as sufficient evidence. They may also confuse an explanation with the measurements and observations used to support it.
How to Assess It: Exit ticket: Four weekly pond counts found 12, 10, 7, and 5 frogs. State the evidence, give a supported explanation, and tell why all four observations matter.

Lesson moves

In groups, observe an ice cube melting every minute, combine class measurements, and write one explanation supported by the full data set.
Discuss: Why is one sighting weaker evidence than 30 recorded sightings when explaining a change in a local bird population?
Play an evidence-or-explanation card sort using statements from a plant growth investigation, then justify each placement.
Compare several days of radar images and rainfall totals, then explain how meteorologists use accumulated observations to describe a storm.
