Nature of Science 1
Kiani conducts an experiment that requires her to throw an object at a target 20 times
What is repetition?
The ability to conduct an electric current, dissolve in water and melt.
What are physical properties?
This describes that something will occur every time in a given set of conditions.
What is a law?
What is the piece of cork?
This is the amount of matter an object contains.
What is mass?
Marquis follows Dante's written procedures for an experiment he did in class last week.
What is replication?
One out of the following is NOT a physical property: density, flammability, boiling point, solubility
What is flammability?
They explain a wide range of observations and evidence, with evidence they are modified and not discarded.
What are theories?
For an object to sink in water it must have a density higher than this number.
What is one?
A measure of the force of gravity acting on an object.
What is weight?
This is the type of evidence you are using if you conduct an experiment and draw conclusions that relies on gathering and evaluating evidence through experiments and observation.
What is empirical evidence?
Mario performed an experiment to investigate how certain substances dissolve in water. He poured the substances in separate beakers of water and stirred each one using a glass rod. He then observed the results. This is the physical property of the substances that Mario investigated.
What is solubility?
An example is an object in motion tends to stay in motion unless another force acts upon it.
What is a law?
Jake and Mary rolled a watermelon into the pool. The watermelon floated in the pool. This tells us what about the watermelon and pool water?
What is the density of the watermelon is less that then density of the water?
This unit can be used to measure both mass and weight.
What is kilograms?
Rashad is conducting an experiment using tennis balls. He completes 30 trials and has 2 of his friends complete the experiment by following his procedures.
What is both repetition and replication?
This physical property is one that remains the same regardless of the amount of matter that is present.
What is volume?
Layla places the same type of plant in locations with different levels of sunlight: full sun, partial shade, and full shade. For five weeks, she records the number of new leaves on each plant. This is the level of sunlight.
What is independent variable?
Serenity wanted to find the density of a silver bracelet. She found that its mass was 24 grams and its volume was 2 cm3. She knows the density is now this value.
What is 12 g/cm3?
This factor affects weight, but does NOT affect mass.
What is gravity?
Tristan wanted to see if the color of water impacted the increase in temperature, in degrees Celsius (ºC), after 30 minutes in the Sun. The temperature is an example of this outcome variable.
What is dependent variable?
You are given two balls that are made from the same material. They are also the same size and color. One is hollow and one is solid.This property can be used to identify the ball that is solid.
What is density?
True or False: With enough evidence and testing a theory can eventually become a law?
What is False (a theory can NEVER become a law)?
The formula to calculate density.
What is mass divided by volume?
A person’s mass on the moon is 70 kg, the same as it is on the Earth. This is what will happen to their weight.
What is the person would weigh less on the moon because there is less gravity on the moon?
