This is the powerhouse of the cell, it provides your cells with energy so they can perform their job.
What is the mitochondria
This law states that matter cannot be created or destroyed, but can be rearranged to form new substances. What is this law?
What is the law of conservation of mass?
Convection of warm moist air takes place off a heated landmass resulting in this phenomenon at 1500+ ft elevation.
what is cloud formation?
This is a segment of DNA that determines our characteristics [height, eye color, skin color, etc].
What are genes?
THIS motion gives us day and night, while THIS motion gives us years and seasons.
What is Rotation and Revolution?
Cells together make tissues, tissues together make organs, organs together make organ systems, and organ systems together make organisms. What is this structure known as?

C3H8 + O2 ---> CO2 + H2O
1, 5, 3, 4
This is the result of the intense interaction between a cold dry air mass and a warm moist air mass.
What is a storm front and/ or precipitation formation?

What is 23 and 46?
What is the greenhouse effect?
In a house, cracks are forming in the walls, around the corners of several doors, and around the windows. The cracks are forming because the house is constructed on unstable ground.
Which of the following parts of the house should be strengthened to prevent the cracks from getting worse?
The foundation
The atoms of this element found in baking soda and citric acid can bond with all other elements because it has four electrons in its outer shell and ______ protons in its nucleus.
What is carbon, 6
This is the result of the rising and falling of nucleated water droplets in a cumulonimbus cloud.

An astronaut drops a hammer on the Moon, and a scientist drops an identical hammer on Earth. Both hammers are dropped from the same height. The hammer dropped on Earth falls to the ground faster than the hammer dropped on the Moon.
Why does the hammer on Earth fall faster than the hammer on the Moon?
The Gravitational attraction is stronger on Earth than on the Moon because Earth has a larger mass.
A student measured three objects made of different materials.
Object: Mass: Volume:
Wood 250g 580cm3
Marble 50g 20cm3
Rubber ball 500g 540cm3
1. How do we find density, and order the materials from least dense to most dense.
Density= Mass/Volume
Wood (0.43g/cm3), Rubber ball (0.92g/cm3), Marble (2.5g/cm3).
