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.
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.
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.
