Up and Atom
"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...
Curated OER
Making Molecules
In this making molecules worksheet, students 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 beads of...

How Are The Properties of Covalent Compounds Influenced By Chemical Bonding?
High schoolers work together to observe the bond lengths of single, double and triple bonds. They make their own predictions about the strength of the bonds and chemical reactions. They answer discussion questions to complete the...

Nuclear Popcorn
Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...
Curated OER
Chemistry - Atoms and Elements
Students perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.

Stereochemistry Problem Set 9
In this chemistry worksheet, young scholars write how many chiral C's are in each of the compounds listed. Then they draw the Fischer projections for all stereo isomers in 5 and in 6. Students also match the correct Fischer projection to...
Curated OER
Chemical Reactions
In this chemical reaction worksheet, students investigate the results of mixing calcium chloride with sodium bicarbonate. They observe the chemical and physical changes that occur, identify the properties of the chemical before and after...
Curated OER
Isomers and Polymers
Students create models of structural isomers, geometric isomers, and polymers. In this chemistry instructional activity, students are given definitions and molecular model kits to create a variety of different isomers and polymers.
Curated OER
Science Hits Activity
Students listen to a song that teaches the elements of the periodic table and write their own song to be used as an aid in remembering scientific information.

Bhopal - Covalent Bonding
Using the chemicals that leaked in the Bhopal gas tragedy of 1984, chemists examine covalent bonds. Provide for them the chemical reactions and have them draw Lewis diagrams for the molecules involved. That's about all there is to the...
Curated OER
Physical and Chemical Changes
Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science instructional activity, 6th graders complete 6 experiments about chemical and physical changes. Students examine the...
Curated OER
Pounds of Pollution
Students examine pollutants and investigate air pollution emitted by a car in a year. In this air pollution lesson students complete an activity and make calculations.
Curated OER
Elements and the Periodic Table
Students are introduced to the elements on the Periodic Table and what is meant by element. Using the Table, they identify the name, atomic mass, number and symbol of each element. To end the instructional activity, they discover the...
