Making Waves
Particles move up an down - perpendicular to the normal or point of origin. This is an example of a ______________ wave
Transverse wave
The point of origin for an Earthquake within the crust.
Focus
If 20 mL of water is added rather than 15 mL of water each day over two weeks to plant A then growth will be faster.
This is an example of a __________
Hypothesis
The interaction of living and non-living things within an environment forms an E__________________
Ecosystem
In the Electromagnetic spectrum the wave with the longest wavelength yet the smallest frequency is a
a) Gamma rays
b) Microwaves
c) Radiowaves
c) Radiowaves
Height of a wave from the horizontal straight line (normal/origin)
a) Wavelength
b) Amplitude
c) Crest
b) Amplitude
The point on the Earths surface normally above the point of origin.
Epicentre
AIM: To determine the melting point of dark and milk chocolate.
Identify the dependent variable (measure)
Melting point (temperature)
Identify a producer.
Vibration of air particles produces .......
Sound
Calculate the wavelength given a velocity of 2m/s and a frequency of 4 Hz.
W = V/f 2/4 = 0.5 m
The movement of tectonic plates up and down that causes Earthquakes is a form of
a) Strike and Slip fault
b) Reverse fault
c) Normal fault
a) Strike and Slip Fault
AIM: To determine the boiling point of milk and dark chocolate.
Identify three controlled variables (constants)
- Same amount of chocolate
- Identical heating source
- Same thermometer
Give an example of an omnivore and outline their diet.
Consume plants and animal products
Frequency is measured in ______
Hertz
Describe sound reflection and given an example.
Sound travels through air and reflects off solid surfaces to produce echo.
Echolocation is an example of sound reflection used by dolphins and nocturnal animals such as bats to communicate during the night.
Describe heat transfer within molten (semi-liquid) magma.
Heat transfer occurs through convection currents.
Hot liquid rises to the surface as it is less dense. This cools down and falls to create circulating convection currents.
In a line graph the HORIZONTAL has the
I____________ Variable (change factor)
In a line graph the VERTICAL has the
D__________ Variable (measure factor)
Horizontal = Independent variable
Vertical = Dependent variable
Give three examples of a decomposer and describe their role in an ecosystem.
ANY of the following;
Maggots, Worms, Bacteria, Some type of fungi
a) Desert
b) Rainforest
c) Bushland
.
Describe one of the properties of light in detail;
a) refraction
b) reflection
c) Dispersion
a) refraction - light changes speed and direction as it passes from one medium to another.
b) reflection - the angle of incidence equals the angle at which light reflects off a reflective surface such as a mirror.
c) dispersion - white light is made of different colours/wavelengths and is broken into these colours/wavelengths when it passes through a glass prism or rain drop (rainbow formed).
A scale used to measure the intensity of an Earthquake. Ten is the highest on the scale.
Richter scale
To determine the melting point (temperature) of milk and dark chocolate.
What goes along the VERTICAL axis (measure)
What goes along the HORIZONTAL axis (change factor)
Vertical = temperature (melting point)
Horizontal = type of chocolate (milk and dark)
Grass --> Rabbit --> Fox
Identify the FIRST TROPHIC LEVEL
Identify the FIRST ORDER CONSUMER
Identify the SECOND ORDER CONSUMER (indicate if its a herbivore, omnivore or carnivore
FIRST TROPHIC LEVEL = Grass
FIRST ORDER CONSUMER = Rabbit
SECOND ORDER CONSUMER = Fox (carnivore)
The absence of air in a vacuum means sound is _______
Not produced and therefore cannot be heard.
