Nature of Science
A student notes that a chemical smells sour and changes from clear to pink. This is the type of data they are recording.
What is qualitative data?
This phase change is when a liquid turns into a solid, like water freezing into ice cubes.
What is freezing?
This property causes water to stick to the sides of a glass tube and climb upward against gravity.
What is adhesion?
This phrase is used to remember the order of metric prefixes in the metric system.
What is “King Henry Doesn’t Usually Drink Chocolate Milk”?
This type of change occurs when wood is burned, resulting in new substances like ash and smoke.
What is a chemical change?
If a scientist records how many centimeters a plant grows each week, this is the type of data they're collecting.
What is quantitative data?
This phase change happens when a solid turns into a liquid, such as ice turning into water.
What is melting?
This force makes water molecules stick together and form droplets.
Answer: What is cohesion?
How many meters are in 3 kilometers?
What is 3,000 meters?
This is the volume of a rectangular solid with a length of 6 cm, a width of 2 cm, and a height of 5 cm.
What is 60 cm³?
This group in an experiment does not receive the treatment or variable being tested, serving as a baseline for comparison.
What is the control group?
This is the process where a liquid turns into a gas, often happening when water boils or evaporates from puddles.
What is evaporation?
Because of this, when water evaporates, it cools the surface it leaves behind, helping living organisms regulate their temperature.
What is high heat of vaporization?
In "King Henry Doesn’t Usually Drink Chocolate Milk," what does “Drink” represent?
What is deci?
On this temperature scale, water boils at 212 degrees under normal atmospheric pressure.
What is Fahrenheit?
This group in an experiment receives the treatment or variable being tested to observe its effects.
What is the experimental group?
This phase change occurs when a solid turns directly into a gas without becoming a liquid first.
What is sublimation?
Water expanding as it freezes helps protect aquatic life and causes this weathering process that cracks rocks.
What is frost wedging?
0.00013 in scientific notation.
What is 1.3 × 10⁻⁴?
What is the density of a rock with a mass of 200 grams and a volume of 50 cubic centimeters?
What is 4 grams per cubic centimeter (g/cm³)?
These factors must remain unchanged across all test groups in an experiment to ensure that the results are due only to the independent variable and not influenced by outside differences.
What are constants?
This phase change happens when a gas cools and changes directly into a solid, like frost forming on a window.
What is deposition?
This term describes the amount of energy needed to change ice into liquid water, which helps stabilize environmental temperatures.
What is heat of fusion?
If a recipe calls for 0.75 kilograms of flour, how many grams is that?
What is 750 grams?
Using this formula, you can convert degrees Celsius to degrees Fahrenheit.
What is °F = (°C × 9/5) + 32?
