Which element is heavier? Phosphorus or Hydrogen.
Phosphorus (100)
What type of rock is pumice, a rock that has visible gas bubbles? Be detailed.
Extrusive Igneous (100)
Name two organ systems.
The Digestive System (100), The Respiratory System (100) and The Circulatory System (100).
In a television that uses 448 J of Light Energy, 325 J of Sound Energy and 205 J of Heat Energy, what is the total net of useful energy?
773 J of Useful Energy (200)
If the independent variable (100) changes then the dependent variable (100) will also change.
What is an element?
One of the simplest form of matter (100) that has mass and takes up space (100).
What is the definition of a mineral?
A naturally occurring, inorganic solid, (100) made from the elements of the periodic table (100).
What is the purpose of villi and where are they located?
Villi are small finger-like structures located in the small intestine (100) that increases it's surface area (100) to maximize it's efficiency (100).
An incandescent light bulb converts it's electrical energy to 80% Heat Energy and 20% Light Energy. A fluorescent light bulb convert's it's electrical energy into 90% Light Energy and only 10% Heat Energy. Which bulb is more efficient and why?
The fluorescent light bulb is more efficient (100) as it converts 90% of it's electrical energy to light compared to 20% for the incandescent (100). This means it has more useful energy converted (100).
In an experiment where the height of a plant is measured when only the type of soil is changed, what are four controlled variables?
Same amount of water (100)
Same amount of sunlight (100)
Same amount of soil (1000
Same environmental conditions (100)
If two elements are from the same group, what will they have in common?
A similar atomic structure (300)
What are four properties of an extrusive igneous rock or how it is made?
Visible gas bubbles (100)
Small crystals (100)
Made from lava (100)
Above ground (100)
Short timescale (100)
Mechanical digestion is the process down using forces (100) like teeth biting, tearing or chewing (100) whereas Chemical digestion uses chemicals such as stomach acid (100) to break down food (100).
Calculate the energy efficiency of the following item:
An Electrical Drill converts 500 J of Electrical energy to 375 J of Movement energy, 50 J Heat Energy, 50 J Sound Energy and 25 J of Light Energy.
375/500 x 100 = 75% efficient

What are the four different types of trends that can be found in data found in tables and graphs?
Highest Value (100)
Lowest Value (100)
Difference Between Highest & Lowest (100)
Average Values (100)
How many element on the Periodic table are naturally gasses? Name them.
2 (200)
Bromine (100)
Mercury (100)
Metamorphic (400)
Rank the efficiencies of the following creatures hearts. Explain why the creature with the highest efficiency is so efficient.
REPTILE, MAMMAL, FISH, BIRD, AMPHIBIAN
Fish --> Amphibian --> Reptile --> Mammal = Bird (300)
The mammal and bird's heart is so efficient as it has four distinct chambers to prevent the oxygenated and de-oxygenated blood from mixing. (200)
Draw an energy flow diagram for the following roller coaster.
Gravitational energy (700 J) Transforms into Movement energy (450 J), Sound energy (200 J) and Heat energy (50 J).
Gravitational (700 J) (100) --> (100) Movement (450 J) (100)
Sound (200 J) (100)
Heat (50 J)
Knowing that an experiment has only one independent variable, propose an experiment.
