The Mechanical Wave Kit helps students explore standing wave patterns at different resonant frequencies. The Mechanical Wave Kit was designed to include everything needed to study wave patterns. This a replacement spring only, that measures .75mm thick wire x 30mm diameter x 60mm length, when...
LED flashlights in three different colors for use in optics experiments. These flashlights can overlap the light from each other to investigate additive color mixing. The on/off buttons are color coded to the light that is emitted. Each flashlight requires one AA battery (included). Specifications:...
These tuning pipes create a long-lasting sound that fills an entire room. Compared to traditional tuning forks, they are much louder and have a more penetrating tone. Made from an aluminum alloy, each pipe is tuned to a specific frequency. The tuning pipe is supported by a wooden handle and string,...
Explore how the different surfaces affect the frictional force on a moving object. This 2-inch square wooden cube has four different faces: bare wood, paper, vinyl and sandpaper. You can explore the value for static and kinetic friction by either pulling on the block or allowing it to slide slowly...
These pulleys are made of black plastic, have a metal housing, and have hooks at the top and the bottom. All wheels are 50mm in diameter except for the smaller wheels on the tandem models. We offer several varieties in both parallel and tandem styles. PRODUCT WARNINGS WARNING: This product can...
The set contains 6 acrylic lenses: one each of double convex, plano-convex, concavo-convex, double concave, plano-concave, and convexo-concave. Includes an activity guide and a reusable cardboard storage box.
