Curated OER
Introduction to Atoms
In this atoms worksheet, students answer four different sets of questions related to atoms (fill in the blank, multiple choice, word puzzle and true and false).
Curated OER
Biochemistry Assignment
In this biochemistry worksheet, students complete a table by filling in the missing information about different elements. Students draw the Bohr diagram and the Lewis dot diagram for several atoms.

What is a Chemical Reaction?
When a candle burns down, what happens to the mass that appears to be shrinking? Lesson begins with a demonstration of the chemical reaction of a candle burning. Then scholars use atom models to observe conservation of mass concretely.

The Making of Macromolecules
Compare and contrast macromolecules made from the same elements. Young scholars learn how the structure of a molecule has as much influence on a compound as the elements in the molecule. They experiment with molecular model kits to...

Why Does Water Dissolve Sugar?
Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...
Curated OER
Water Cycle Activity
Students build a model and observe the cycle of evaporation and condensation that occurs in the water cycle. They see how the water cycle works, such as water condensing on the side of the jar and drops precipitating into rain that...

Interpreting Chemical Formulas
In this chemical formulas worksheet, learners practice naming molecular compounds by their formulas and determine if a gas is a compound or an element. This worksheet has 13 fill in the blank questions.
Curated OER
Making Molecules
In this making molecules worksheet, young scholars complete a table of elements with their symbol, atomic number, atomic mass, number of protons, number of electrons, period and group. Students then make models using pipe cleaners and...
Curated OER
Different Minerals
In this minerals worksheet, students read about the relationship between elements, rocks and minerals. They experiment using 6 different colored gumdrops to represent 6 common elements. Students construct gumdrop and toothpick models of...
Curated OER
Periods and Groups; Valence Electrons; Masses
In this periods, groups, valence electrons and masses worksheet, students are given information about all these components of the periodic table. Students identify 4 elements in specific periods and groups, they find the valence...

Stoichiometry
Watch your class react when you tell them they're going to study stoichiometry! The lesson demonstrates four examples. Scholars must write and balance the chemical equation and then make the conversion to find the correct mass or volume....
Curated OER
The Air Up There!
Students create a model of a column of air and discover one of the reasons why low and high pressure systems exist and why low pressure is often associated with bad weather.

Where Does a Plant's Mass Come From?
Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.
Curated OER
Ionic Nomenclature
One document contains five different worksheets for practice naming and writing formulas for ionic compounds. The first is particularly notable, as it systematically walks beginning chemists through the process of using the periodic...
