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.
You can use our prefolded mini toober model of ß-globin to demonstrate protein structure, the important role of hemoglobin in oxygen transport, and the lasting effects of a single amino acid mutation on a protein. Some teachers purchase it in conjunction with the B-Globin Folding Kit to use as a sample model. The model also reinforces lessons introduced in our Amino Acid Starter Kit©.
The sky is the limit to what you can teach using these new large-scale,
color-coded foam nucleotides. Begin by teaching the complementary A-T
and C-G base pairs and the antiparallel nature of double-stranded DNA.
Move on to the flow of genetic information as you teach the basic
processes of semiconservative DNA replication and mRNA transcription.
You can then stretch your students by introducing PCR (polymerase chain
reaction) and the Sanger DNA sequencing method -- and much more.
