Light Waves
Black balloons absorb most colors of the light spectrum. True or False?
True
The three states of matter are solid,
gas
3x + 2 - 1
3x + 1
12x = 24
x = 2
What is the name of your assistant Principal?
Mr. Lynch
The distance between two consecutive crests (peaks) or troughs (valleys).
Light waves
Anything that has mass and takes up space (volume).
Matter
11m + 3x -5 -3m
8m + 3x -5
3x + 7 = 22
x = 5
Which day of the week does Halloween fall on this year?
Saturday
Light bounces off a surface. Smooth, shiny surfaces (like mirrors) form clear reflections, while rough surfaces scatter light.
Reflection
A state of matter with an indefinite shape and an indefinite volume. It expands or compresses to completely fill any container.
Gas
10m + 4 - 3m + 6
7m + 10
4m + 8 - 2m = 16
m = 4
What sport does Addie play?
Lacrosse
Objects absorb certain wavelengths of light and reflect the wavelengths that match their color (e.g., a red apple reflects red light and absorbs the rest). [1, 2, 3, 4]
Color Perception
A state of matter with an indefinite shape but a definite volume. It takes the shape of its container but cannot expand to fill it.
Liquid
2x² + 7x + 5x² - 3x - 8
7x2 + 4x - 8
-2(3a - 4) = 20
a = 2
What sport does Katie play?
Soccer
is the bending of a light wave as it passes from one material (medium) into another
Refraction
changes in matter that alter its physical properties—such as its shape, size, or state—but do not change its chemical identity
.
Physical Change
2(3a + 4) + 5a - 1
11a + 7
5a + 14 - 2a = 7a - 2
4 = a or a = 4
