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.

• 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!

• Distinguish between multipolar neurons, bipolar neurons, unipolar neurons and interneurons, and determine their location and function in the human body.
• Construct a model and identify parts of a multipolar neuron.
• Use myelin sheath pieces to demonstrate differences between two types of neuroglia in the central and peripheral nervous systems.
• Construct simple and complex neural pathways and examine the overall effect on neuronal firing at excitatory and inhibitory synapses.
