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!

Introduce your students to the CRISPR system and prepare them to consider how the CRISPR-Cas9 protein is being used to edit the human genome. Model the different parts of the CRISPR system and explore how the bacteria develops immunity over time.

Explore the CRISPR-Cas9 protein and help your students consider how it is being used to edit 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!
