A FUN tool to help you teach water concepts. Your students will use these magnetic water molecules to discover hydrogen bonding, make ice, dissolve salt, evaporate water, explore transpiration, create ethanol, and much more.

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.

Model how the Cas9 protein is programmed with RNA to search for and identify specific sequences of DNA before making the double-stranded cut. Explore and discuss how Cas9 is being engineered with new features that make it a useful tool for editing the human genome.

• Model chromosome structure and anatomy.
• Construct Punnett squares to connect inhericance of traits to chromosomes at the molecular level.
• Compare and contrast mitosis and meiosis.
• Model mechanisms that contribute to genetic variation.
• Model chromosomal aberrations such as nondisjunctions, translocations, inversions, deletions and duplications.
• And much more!
