PS4-1
Describe why your wave has a GREATER VOLUME, but is the SAME TYPE or note of sound as the one shown in Graph 1.
CFS:
- Accurately identifies how a different wave properties impact light and sound
- Accurately describes how differences in waves impact how we see or hear them

PS4-2
Many of us have been to a lake or the ocean and have seen how things look different with water. For example when we stand in the water our feet might look smaller or larger from outside the water.
(example below)
Below is an image of several light interactions. Explain why a rock that might appear straight ahead from above water is actually askew as shown by the rock placement below.
CFS:
- Accurately identifies the correct light interaction based on visual data
- Accurately describes how specific light interactions impact how we see or view an object in the real world

Both Electromagnet System 1 and Electromagnet System 2 are held in place before they are released. Before they are released, which system has more PE? Explain.
CFS:
Describes the energy in a single magnet or a magnetic system
Accurately describes the relationship between changing variables (distance; attract/repel) in a system and magnetic PE’
HINT: are the magnets attracting or repelling
