Take your salt crystal lessons from 2-D to 3-D. These colorful sodium chloride ion models will help your students discover the cubic nature of salt crystals, efficient lattice packing, high melting temperature, brittleness and cleavage planes.

This engaging, hands-on protein-folding kit makes teaching protein structure basics easy. Your students will fold a protein while exploring how the chemical properties of amino acids determine its final structure.

ß-globin becomes real in your students’ hands as they fold mini toober fragments into a 3-D protein model of ß-globin. Your students will discuss oxygen transport as they attach O2 to the iron in the heme group and then explore how a single mutation causes sickle cell anemia.

Help your students achieve a better understanding of multiple biotechnology concepts including diagnostics, forensics, and bacterial transformation with a single hands-on modeling kit! Using the color-coded foam nucleotides in the Biotechnology Kit^© and teacher-developed activities, students:

• Model polymerase chain reaction and how flanking primers result in the exponential amplification of a short product.
• Model the Sanger DNA sequencing method using chain-terminating fluorescent dideoxy nucleotide analogs.
• Model DNA cloning using restriction endonucleases to cut DNA at specific sequences.
• And more!

Discover how bacteria remember past viral infections and activate their CRISPR systems to search for and destroy the remembered virus’ DNA - preventing infection. This introduction to CRISPR biology will prepare your students to use Making the Cut with CRISPR-Cas9 and understand how the Cas9 protein works.
