Prior to watching the digital tool, give students a 4x6 note card and instruct them to draw a large wave moving toward a beach. The teacher may need to model this on the board in order for the wave to have a trough, wavelength, and crest. Next, have the students create a beach scene.
As the students watch the digital tool, "Wave Trait," they will label the card and write the definition the each of the terms on the back of the card. (The video may need to be paused for the slower students in the class so they have time to write the information).
Once all the students have finished with their cards, then have the students to turn and talk to a peer and share their illustrations.
- Next, have all the students to line up and join hands. (They will be doing the wave.)
- At different intervals say stop and ask a student to identify if his or her hand is at a trough or crest.
- Repeat the wave motion but speed up the command and ask a student to describe his or her observations.
- Continue to play the wave activity until students have a good understanding of the properties of a wave.

Whole Group Instruction:
- A rope (at least 10 feet long)
- Two student volunteers
- Piece of tape (colored tape works best)
1. Put a piece of tape in about the middle of the rope.
2. Tie the rope to something or let the student hold on to one end of it.
3. Pull the rope so that it is a bit slack but not quite touching the floor.
4. Instruct the student to move his or her arm up and down.
5. Repeat the motion at a faster pace (not too fast) and see the results. Be sure to point out the action of the tape in the middle of the rope.
6. Whole group discussion based on the observations of the class related to wavelength, frequency, and amplitude.
Individual Wave Model:
Materials: yarn, construction paper, ruler, and glue
Give students a sheet of construction paper and tell them to write a title:
Next, students will draw a straight line across the middle of the construction paper about 8 inches long.
This will be the resting point of the wave.
Now, the students will glue/tape the yarn to create a wave that has various frequencies, wavelengths, and amplitudes.
Finally, have the students to label their model.
