Miscellaneous
If a solid block with a density of 2.7 g/cm³ is placed in fresh water (density 1.0 g/cm³), it will do this.
It will sink
Calculate the density of a sample with a mass of 35 g and a volume of 17 cm³.
What is approximately 2.06 g/cm³ (or 2.1 g/cm³)?
This graph type usually presents data as percentages or as "parts of a whole."
What is a pie graph (or circle chart)?
On a standard scientific graph, the independent variable is always plotted on this axis.
What is the X-axis?
A vertical column on the periodic table is called this.
What is a group (or family)?
When a large cube is broken into smaller irregularly shaped pieces, this is how the density of the pieces compares to the original whole cube.
What is equal / remaining the same?
Calculate the mass of a liquid that has a density of 3.2 g/mL and a volume of 25 mL.
What is 80 g?
This type of graph features connected points showing continuous dependent data where each value depends on the previous observation over time.
What is a line graph?
On a standard scientific graph, the dependent variable is always plotted on this axis.
What is the Y-axis?
A horizontal row on the periodic table is called this.
What is a period?
Selenium (Se) is located in Group 16 (6A), which means it has this many valence electrons.
What is 6?
An irregular object with a mass of 18 g displaces 2.5 mL of water in a graduated cylinder. This is its density.
What is 7.2 g/cm³ (or 7.2 g/mL)?
Unlike bar graphs, this graph type has touching vertical bars because data is grouped into defined numerical "chunks" or continuous ranges.
What is a histogram?
In an experiment testing how jar volume (mL) affects candle burning time (seconds), this variable goes on the X-axis.
What is jar volume (mL)? (Independent variable)
As you move down a group on the periodic table, the number of energy levels increases while this value stays the same.
What is the number of valence electrons?
Iodine (I) has an atomic number of 53 and an atomic mass of approximately 127. This is its number of neutrons.
What is 74? (127 - 53 = 74)
A block measures 2.0 cm by 2.0 cm by 3.0 cm and has a density of 2.7 g/cm³. This is its mass.
What is 32.4 g? (Volume = 12 cm³)
This graph type uses a line or curve of best fit to map independent data points plotted with x- and y-components, such as height vs. arm length.
What is a scatter plot?
In an experiment where a ball is dropped from different heights (meters) and its rebound height (cm) is measured, rebound height is this type of variable.
What is the dependent variable?
As you move across a period from left to right, the number of energy levels stays constant while this value increases.
What is the number of valence electrons (or atomic number / protons)
Drawing a Bohr diagram for Fluorine (atomic number 9) requires placing this many electrons in its second energy shell.
What is 7 electrons? (2 in the first shell, 7 in the second)
Calculate the density of a board measuring 5.54 cm x 10.6 cm x 199 cm with a mass of 28.6 g.
What is 0.00245 g/cm³ (or 2.45 × 10⁻³ g/cm³)? (Volume = 11,686.08 cm³)
This graph type is best used when the dependent variable is NOT continuous and categories on the x-axis have no set natural order (e.g., preference for Coke vs. Pepsi).
What is a bar graph?
When graphing the growth of duckweed leaves over a 5-day period, this variable is placed on the Y-axis.
What is the number of leaves? (Dependent variable)
Elements located along the staircase line dividing metals and non-metals belong to this chemical class.
What are metalloids (or semimetals)?
