".2mL PCR tubes"

This bell jar demonstrates that sound waves can't travel and therefore can't be heard without air or matter.

Explore a full range of motion with the advanced hydraulic arm

100 feet of extra tubing for TeacherGeek projects.

The Student Coin and Feather Tube shows the two items in a vacuum, falling at the same rate.

This demo features a cathode beam to explain the electromagnetic nature of electrons.

The Centripetal Force Kit is inexpensive and effective.

This vacuum plate and pad are the perfect tools for vacuum experiments.

Ideal for Index of Refraction and Total Internal Reflection Experiments

This newly designed rheostat features a protective cover.

Students Investigate Alternative Energy Forms

Ideal for demonstrating that vapor pressure increases when temperature increases.

Effective Method of Showing Normally Invisible Currents

Enough materials for a complete class to perform all of the electrostatics experiments included in this set.

The movement of liquid currents due to differences in temperature is demonstrated by introducing dye into the water in the tube. One corner of the tube is heated and the movement of the dye clearly establishes the currents. The rectangular shaped tube measures 15×21 cm and has an opening at the top.

Glows with Characteristic Brilliance!

The Speed of a Bubble Set connects the mathematical concept of slope to the physical science concept of velocity.
