How many moons does Earth have?
1
True or false? All living things are made up of cells.
True.
What is matter?
Something that takes up space and has mass.
What are the 3 types of heat transfer?
Conduction, convection, and radiation.
What is input force?
The input force is applied to the lever.
Is the sun a planet or a star?
A star.
What are the 5 organ systems?
Circulatory, respiratory, digestive, musculoskeletal, and nervous.
What are the 3 states of matter?
Solid, liquid, and gas.
What is conduction?
the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
What is output force?
The force the lever applies to the load.
Which planet is the closest to the sun?
Mercury.
What is the musculoskeletal system job?
support, protection and movement.
What temperature does it need to be for water to turn into ice?
0° C (32° F) or lower.
What is convection?
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
What is the load force?
The force that the input force has to overcome to create movement.
Which planet is the hottest?
Venus.
What is the circulatory system job?
transports nutrients, etc.
What does solvent mean?
able to dissolve other substances.
What is radiation?
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.
What is systems thinking?
Thinking about how the parts of a system work together and how they affect people and the environment
Is the sun the largest star?
No.
What is the nervous system job?
Responds to changes in environment and coordinates the functions of all the other organ systems.
What does solute mean?
The minor component in a solution, dissolved in the solvent.
What is chemical change?
Chemical changes are those where one or more substances are combined to produce a new substance. At the end of a chemical change, you have a new substance. Burning a piece of paper would be a chemical change, as would baking a cake.
How to calculate work
Work is the energy exerted by an object as it applies a force to move another object over some distance. For a given amount of force, F, and a given distance, d, the work done on an object is given by the formula W=F⋅d W = F ⋅ d .
