A disturbance is another name for a force.
Interactive Notebook
You will be in different stations in groups doing different things. There will be a procedure for you to follow at each station.
Don’t forget to:

The stations
Metal stations.
Vanishing Content
A transverse wave’s energy moves
perpendicular to the force which caused it
to move.
Vanishing Content
Frequency is the number of times a
wave cycles in a second.
Vanishing Concept
Pitch or note is determined by frequency.
How are the two waves different and how are they the same?
longitudinal wave and transverse wave.
Describe where the compressions are.
Describe where the rarefactions are.
Vanishing Content
An earthquake primary (P) wave is a longitudinal wave
Vanishing Content An earthquake secondary (S) wave is a
transverse wave.

Wave Properties• Amplitude –
This is the energy of the wave. The bigger the amplitude the more energy the wave has.
Wavelength –
The distance from crest to crest or trough to trough.
Frequency – the speed of the wave
The number waves passing a fixed point in a certain amount time
Test today on waves
Where is the crest?Describe the crest in words.
Where is the trough?Describe the trough in words
What do call the measurement from the crest of one wave to the crest of the next wave?
crest
trough
Wavelength
What is the distance between two adjacent crest or troughs on a wave?
Wavelength
Short review
2. Interference – when two waves collide.
a) constructive interference
In phase
=
Constructive interference happens when two waves are in phase to add to make one big wave.
Waves Strengthen each other
b) Destructive Interference
Out of phase (overlap)
=
Destructive interference happens when two wave are out of phase and cancel each other out.
Waves cancel each other

Vanishing Concepts
Temperature describes the movement of the particles.
The direction of heat is from warmer objects to cooler objects.
Summarize this writing
The word ecosystem is short for ecological systems. An ecosystem includes all of the living organisms in a specific area. These systems are the plants and animals (biotic) interacting with their non-living environments - biotic (weather, Earth, Sun, soil, atmosphere). An ecosystem's development depends on the energy that moves in and out of that system. As far as the boundaries of an ecosystem, it depends upon how you use the term. You could have an entire ecosystem underneath a big rock. On the other hand, you could be talking about the overall ecosystem of the entire planet (biosphere).
Summarize this writing
An ecosystem includes the living (biotic) and nonliving (biotic) parts, plus the energy that moves within it. It can be small or large.

Each lunar cycle starts and ends with the new moon.
The waxing phase indicates that moon appears to grow.

Why plants have leaves
Leaves make food for the plant.
Sum up the thought, but keep the meaning of the paragraph.
Why plants have leaves
Leaves make food for the plant. The sun shines on each leaf.
Why plants have leaves
All the green parts of the plant make food for the plant. The sun shines on each leaf. Sunlight gives the leaf energy to make the food. The food is made from water, soil and carbon dioxide. This is called photosynthesis.

Why do plants have roots?
All plants with flowers have roots.
Why do plants have roots?
Plants have roots for two main reasons. 1)Roots anchor the plant in the soil, and prevent it from being blown away by strong winds. 2)Roots also take up water and minerals, such as nitrogen and sulfur, from the soil. Plants need water to replace that lost by transpiration, and minerals to make substances for life.
Bactria in soil help the plant take up nitrogen, minerals and sulfur in the rooms
