Matter & Properties
Solid, liquid, and gas are the three common examples of this physical property.
What is State?
This is an unfair influence that can affect how evidence is collected, interpreted, or communicated.
What is Bias?
These two SI units are commonly used to measure mass.
What are grams and kilograms?
This is the amount of matter in a solid, liquid, or gas.
What is Mass?
According to this model, all matter is made of tiny particles that are always moving and have spaces between them.
What is the Particle Model of Matter?
This physical property describes the amount of space taken up by matter.
What is Volume?
Sam believes heavy objects always sink, so she records only the trials that support her belief. This type of bias involves favouring evidence that agrees with what you already think.
What is confirmation bias?
These are the correct abbreviations for grams, kilograms, millilitres, and litres.
What are g, kg, mL, and L?
This laboratory instrument is used to measure mass.
What is a balance? or What is a weight scale?
In this state, particles are close together and vibrate in place.
What is a solid?
This is the ability of matter to decrease in volume when pressure is applied.
What is Compressibility?
A class surveys only the soccer team to decide which sport is most popular in the entire school. This bias occurred because the sample did not represent the whole population.
What is sampling bias, or selection bias?
A soda can holds 355 of these metric units
What are milliliters?
To accurately read liquid volume in a graduated cylinder, your eyes should be at this position.
What is eye level with the liquid’s surface or meniscus?
In this state, particles remain fairly close but can slide past one another.
What is a liquid?
A student records that an object is a solid, has a mass of 40 g, takes up 20 mL of space, and sinks in water. The student is recording these kinds of properties.
What are physical properties?
A balance always displays 2 g more than the object’s actual mass. This type of bias is caused by an inaccurate measuring tool or procedure.
What is measurement bias?
This amount of grams is equal to 1 kilogram.
What is 1,000 grams?
Block A and Block B have the same volume. Block A has a mass of 60 g, while Block B has a mass of 35 g. This block is denser.
What is Block A?
In this state, particles have large spaces between them and move constantly in all directions.
What is a gas?
Before measuring the mass of a liquid, a student places an empty container on a digital balance. What should the student do next, and why?
What would be to "tare" or zero the balance before adding the liquid. Preventing the container’s mass from being included in the liquid’s measurement.
or
What would be to subtract the empty container’s mass afterward?
Two groups test whether salt affects how quickly ice melts. One group uses different-sized ice cubes and different amounts of salt. This important scientific feature is missing from their investigation.
What is a fair or controlled test? or What is controlled variables?
Four bottles each contain 250 mL of water. Together, they contain this volume in liters.
What is 1 liter?
Corn syrup sinks below water, but oil floats on top of water. Place the liquids in order from most dense to least dense.
What are corn syrup, water, and oil?
Attractive forces between particles are strongest and weakest in these two states.
What are solids and gases?
