Introducing waves! The prelude to Working with WAVES curriculum is called Float Boats. Different types of boats are built for students to learn about waves:
What is a wave? A gesture or single with your hand, a swell on surface of water. The word wave has many different meanings but it always refers to a back-‐ and-‐forth movement or a rising and falling motion. What causes waves on water? Wind. A swell on water’s surface is caused by wind. Stronger winds like storm surges causes larger waves. Waves also happen in water from vibrations. DEMO: (Using a filled water trough and a pebble) What happens when we toss a pebble into a still body of water? Vibrations happen -‐ rings of waves appear that expand out.
