Choose a covering from a record

Supplied materials

• For younger learners, an adult may read each direction aloud; pointing, drawing and spoken explanations count as responses.
• Paper, drawing space or a browser document.
• Reference card A: water stays on the outside in this card. Reference card B: water enters the sample in this card.
• Assessment case 1: Which scientific label fits the specifically described step or feature? Supplied case: Droplets stay outside the sheet.
• Assessment case 2: Which scientific label fits the specifically described step or feature? Supplied case: A cloth takes in the droplets.
• Assessment case 3: Which scientific label fits the specifically described step or feature? Supplied case: A cover blocks the beam.
• Assessment case 4: Which scientific label fits the specifically described step or feature? Supplied case: A clear sheet passes the beam.
• Assessment case 5: Which scientific label fits the specifically described step or feature? Supplied case: A wrapper keeps the paper dry.
• Assessment case 6: Which scientific label fits the specifically described step or feature? Supplied case: A window sheet lets light through.

Learn the idea

A material choice depends on the purpose. These pretend test cards show what happened to water and light. They do not mean every sample of a material behaves identically.

Water blocker means water stays on the outside in this card. Water soaker means water enters the sample in this card. Light blocker means the card says no light passes through. Light passer means the card says light passes through.

For water blocker, look for the clue “water stays on the outside in this card.” For water soaker, look for “water enters the sample in this card.” More than one process can happen in a real situation. Answer about the one described in this question.

1. Read or listen to the four science words and what each means. Say how the first two differ.
2. Choose two of the short cases. Point to the clue that helps you choose a science word for each one. You may draw or say your answer.
3. Answer each practice question. Say which clue helped you, then check the explanation.
4. Use the extra task to make two examples that show different science words. Draw or say what makes each one fit.

Take it further

Create one new case showing water blocker and one showing water soaker. Expected: the first explicitly shows “water stays on the outside in this card”; the second explicitly shows “water enters the sample in this card.” Explain the distinction by drawing, speaking or writing. A label without a matching feature is incomplete.
