Investigating Science
The unit used to measure force.
What is a Newton (N)?
Solid, liquid, and gas.
What are the three common states of matter?
A push or a pull.
What is a force?
All organisms are made of these basic units of life.
What are cells?
Rocky (terrestrial) planets and gas planets.
What are the two types of planets in our solar system?
The variable that you deliberately change or manipulate in an experiment.
What is the independent variable?
The process where particles spread out from high concentration to low concentration.
What is diffusion?
The force that opposes movement of one surface over another and produces heat.
What is friction?
Cell wall, chloroplasts, and large vacuole.
What are three structures found in plant cells but not animal cells?
How the Moon becomes visible, unlike the Sun which creates its own light.
What is reflected light?
When you read a measuring cylinder, you must read this curved surface of the liquid at eye level to avoid parallax error.
What is the meniscus?
Mass divided by volume.
What is the formula for density?
Magnetic, electrical, and gravitational.
What are the three types of non-contact forces?
The process in chloroplasts that provides glucose for the cell.
What is photosynthesis?
The model that places the Sun at the center of the solar system.
What is the heliocentric model?
This piece of lab equipment has a blue flame when the air hole is open and a yellow flame when it's closed.
What is a Bunsen burner?
In a solution, the substance that dissolves, like salt in water.
What is the solute?
The equation W = mg, where W is weight, m is mass, and g is gravitational acceleration.
What is the formula for calculating weight?
Kingdom, Phylum, Class, Order, Family, Genus, Species.
What are the seven levels of biological classification?
Day and night, seasons, leap years, and eclipses.
What are phenomena caused by the relative positions of the Sun, Earth, and Moon?
These three qualities assess how good an experiment is: repeating for patterns, changing only one variable, and correctness of measurements.
What are reliability, validity, and accuracy?
Filtration, evaporation, distillation, chromatography, and crystallisation are examples of these.
What are separation techniques?
The constant speed reached by a falling object when air resistance equals gravitational force.
What is terminal velocity?
Fish, amphibians, reptiles, birds, and mammals.
What are the five vertebrate groups?
Space telescopes, radio astronomy, and planetary rovers and landers.
What are technologies that have increased our understanding of the universe?
