Science & Engineering Practices
Data or information gathered using your senses about a situation.
What is an observation?
A tool that measures precises liquid volume in mL.
What is a graduated cylinder?
When a substance changes from a liquid to a solid.
What is freezing?
The whole number that is unique to each element, organizes the periodic table in ascending order, and is equivalent to the number of protons and electrons.
What is Atomic Number?
The distance an object can travel over time.
What is speed?
The part of a controlled experiment that is manipulated by the experimenter.
What is the independent variable?
Metric unit for work.
What is Joules (J)?
When a substance has a density greater than 1 g/mL.
What is sinking?
The number, usually a decimal, on the periodic table that describes the number of protons and neutrons in one atom of an element.
What is Atomic Mass?
The work done when a 100 N box was pushed a distance of 8 m.
What is 800 J?
The conditions that have to remain the same during an experiment to ensure accuracy and reliability of results.
What is the controls/constants?
The metric base unit for measuring mass?
What are grams? (g)
The temperature at which a substance turns from a liquid to a gas.
What is boiling point?
When a chemical reaction takes place in a container that is not sealed and this allows for air or other substances to enter or exit the system.
What is an open system?
The measurement of how much energy something has.
What is temperature? (Heat)
When the evidence collected about something does not support the claim.
What is refuting a claim?
Metric unit for density.
What is g/mL or g/cm3?
A method for separating a dissolved substance from a liquid.
What is evaporation?
What is evidence of a chemical reaction occuring?
When a substance loses energy and changes from a gas to a liquid.
What is condensation?
The scientific rule or principle that explains how or why evidence supports a claim.
What is reasoning?
If a small rock was dropped into graduated cylinder with 50 mL of water in it and the water level rose to 65 mL, what is the volume of the rock?
The ability of a substance to be dissolved in 100 grams of water at a certain temperature.
What is solubility?
If there are 50 grams of baking soda combining with 100 grams of vinegar, how many grams of total products would there be left after the reaction took place?
150 grams (law of conservation of mass)
When a force is applied to an object and it moves in the same direction as the force being applied to it.
What is work?
