"Avantor"

Incredibly simple alternative to traditional force tables.

Investigations Into magnetic fields, force, and poles.

Students build two different gliders — a hamburger shaped glider and a hot dog shaped glider.

Use these thin-section slides with a polarizing microscope to view rock specimens in detail. Includes: biotite granite, olivine basalt, red sandstone, encrinal limestone, mica schist, augen gneiss, storage box and identification guide.

Note: collections are subject to change depending upon availability of individual items. Set of six.

Matter has mass and takes up space. With this exciting kit, students explore the relationship of mass and volume using a spring scale and hook weights and observations.

Different sizes and materials to fit all your classroom needs.

Ideal for studying collisions in two dimensions, these pucks can be supported on plastic beads or levitated with air from the balloons to reduce friction. Use on any smooth, flat surface. The pucks measure 10 cm in diameter, and one puck is twice the mass of the other two.

Corks

Planaria are a flatworm commonly used in science fair projects. They do not bite and move very slowly, making them easy for young students to observe.

These DNA markers are used to determine size of unknown DNA fragments. If using within 2–3 days, they do not need to be refrigerated and can be stored right on a shelf. If storing for longer time periods, freezing is recommended.

Ship date is required.

Vanessa cardui Butterflies form chrysalides and transform into colorful butterflies right before your eyes.

Bullfrog tadpoles are great for demonstrating metamorphosis in the classroom.
