Esters from Alcohols and Acids
Fats and oils often contain esters, which sometimes find their way into perfumes due to their pleasant smells. Scholars match the name of esters made from four different types of alcohol and four different types of carboxylic acids....
Royal Society of Chemistry
Crude Oil
The United States consumes more oil than any other country, and its residents use 50 percent of that for transportation. Scholars match eight fractions of crude oil to their applications. Then, they fill in three logic puzzles reviewing...
Royal Society of Chemistry
Alkalis
Because they are reactive with air and water, scientists store alkalis in oil. Scholars complete a series of four puzzles reviewing information about alkalis. They match the alkali to its formula, the salt formed with H2SO4, and the salt...

Elements 2
Did you hear about the chemist reading the book about helium? He couldn't put it down. Scholars match 12 chemical elements, including helium, to their symbols. Then they complete three Sudoku-style puzzles using these names and symbols...
Royal Society of Chemistry
States of Matter 1
Do solids, liquids, and gases even matter? Scholars match the state of matter to its particle picture, size and shape description, and description of the arrangement of the particles. Once they complete that activity, they complete a...
Royal Society of Chemistry
Rock Types 1
If pupils think the three types of rock are classic, punk, and hard, these puzzles offer gentle correction. Scholars match the type of rock to how it formed and an example in four grid puzzles. Each requires problem-solving and...

Periodic Table 2
While the periodic table looks complex, it is really arranged by only two variables, atomic number and electron configuration. The set of four puzzles focuses on groups 3, 4, 5, and 6 or 13, 14, 15, and 16, depending on your periodic...
Royal Society of Chemistry
Periodic Table 1
Richard Feynman predicted the periodic table might go up to number 137—but never to 138. Scholars practice naming which elements belong in groups 1, 2, 7, and 0 on the periodic table in puzzles. They work through four puzzles reinforcing...
Royal Society of Chemistry
Naming Binary Compounds
Penguinone is an organic compound named because it resembles a penguin. Scholars match the name of binary compounds to the elements in each compound. Then, they solve three sets of puzzles reviewing the same content.
