4-PS4-3
The standard
Generate and compare multiple solutions that use patterns to transfer information.
Next Generation Science Standards
What this standard means
Students need to design more than one way to send a message using a pattern. The pattern might be sounds, flashes, taps, symbols, colors, or numbers. They also need to test the options and compare them, not just make one code and stop.
Mastery looks like a student explaining how the pattern stands for information, using it to send a clear message, then judging which design worked better and why. Students often get stuck making codes that are fun but hard to use. They may also compare by opinion instead of evidence, like speed, accuracy, distance, or ease of decoding.
Ways to teach it
- Give pairs cups, sticks, flashlights, and grid paper, then have them build two ways to send the word HELP across the room.
- Ask students to write: Which code worked best for your team, and what evidence from your test proves it?
- Hand students a short coded message in dots and lines, then ask them to decode it and name the pattern rule.
- Show a QR code, barcode, or crosswalk signal, then have students identify the pattern and the information it sends.
