Have a 3D printer? Make some 3D printed models of various carbon allotropes!
Tissue paper can be folded and cut with chemistry-related patterns to make decorative paper banners that can be used as Mexican-themed decorations. Chemistry concept connections include lattice energy, bandgap energy, and ionic crystal fracture.
Regularly dimpled trays such as those used in food packaging can be used to represent layers of atoms in solid structures. For example, the square array of dimples in transparent plastic mini quiche trays can be used to depict layers within cubic or tetragonal unit cells. Multiple solid structures and ways to represent those structures are described.
Molecular geometry is a center piece to a student’s understanding of intermolecular forces. Unfortunately, many students don’t have the special skills to “see” the geometry without a model kit. Check out this inexpensive take-home model kit!
The shapes of plastic bottles can be used to represent orbitals. Using various connectors, a bit of packing tape, and a few other more specialized touches can produce large scale molecular models that feature orbitals, sigma bonds, and pi bonds.
Egg cartons and small objects such as milk jug caps or plastic eggs can be used to illustrate chemical concepts. The egg cartons can be cut into trays to represent atoms or to represent energy levels associated with atomic orbitals. The plastic caps or eggs distributed among the dimples of the trays can be used to represent electrons or pairs of electrons.
Sometimes the obvious is the most difficult to see. Even after teaching for four decades, there is still something to learn from students. What did I recently learn? Check out my post.
Explore how small the stuff that makes up matter is and consider what those tiny particles are doing in this engaging activity.
The use of multiple representations helps to characterize students' understandings and their misconceptions. Stacey Lowery Bretz shared multiple resources and strategies for using them in her ChemEd X Talk. The recording is available here!
This engaging activity uses wrapped and unwrapped candy to simulate alpha and beta decay.
