Ask a Question
What does a ruler measure?
Length
What is the difference between mass and weight measurements?
Mass is the amount of matter and weight factors in the force of gravity.
What is the formula for volume?
V = L x w x h
After you form a hypothesis, what would you do next?
Perform an Experiment
What is the total amount of matter in an object?
Mass
What will happen if you put an object that has a density greater than 1.0 g/mL in a beaker of water?
It will sink since the object is denser than water.
What is the formula for density?
D = m/v
Should you collect and analyze data first OR communicate your results first?
Collect and analyze data
What is the total amount of space occupied by a substance?
Volume
What would you use to measure the volume of a glass of milk? What units would it be?
Graduated cylinder, mL
When using a graduated cylinder, if the initial volume is 50 mL and the final volume is 85 mL, what is the volume of the object?
35 mL
Research your question
What is the ratio of mass per unit volume of a substance?
Density
What would you use to measure the mass of a pair of scissors? What units?
Triple beam balance, grams (g)
If the riders on the triple beam balance show 200 g, 30 g and 6.5 g, what is the mass reading?
236.5 g
What is an example of an observation?
Ex. The water is cold. The music is loud.
What is the measure of the pull of gravity on an object?
Weight
What would you use to measure the weight of a bag of apples? What units?
Spring scale, Newtons
