How do the stretch properties of a rubber band compare to these of a spring? With this hands-on lab, students experiment with these two different elastic materials to determine the relationship between the stretch distance and the force exerted by... AP7201 - $102.00

Engage your students with this all-in-one pressure kit! Four hands-on lab activities allow students to explore the fundamental principles related to pressure. Students experiment with mini Magdeburg hemispheres to feel the strength of atmospheric pressure.... AP6220 - $52.50

Eureka! Quickly and accurately measure an object's mass and
volume-with one apparatus! How is this possible? This unique balance
utilizes Archimedes' principle of fluid displacement and buoyancy
force-the same principle used to explain why a 500-ton... AP6380 - $38.90

Archimedes ran through the streets of ancient Greece shouting “Eureka!” when he realized how he could utilize his density and water displacement experiments to demonstrate that the king's crown was made of pure gold. Students can discover Archimedes'... AP7004 - $19.40

In a chemical reaction, matter is neither created nor destroyed-except in this discrepant event demonstration! Let students discover what is really measured when something is “weighed” on a balance. First carry out a gas producing reaction in a capped... AP4632 - $15.80

Simple device with a multitude of demonstration possibilities. The rod responds to changes in density of a liquid by sinking or rising in the liquid. As the density of the liquid is changed, the rod moves up or down accordingly. It sinks in warm water... AP6058 - $32.80

Here's a handy, low-cost set of 10 one-inch cubes cut from modern materials. Use these precision cubes to perform a variety of density experiments. The set contains one cube each of aluminum, steel, brass, copper, acrylic, oak, nylon, pine, poplar,... AP6069 - $14.00

The “normal” density rod (AP4632) sinks in warm water and floats in cold water. The reverse density rod works just the opposite! It will float in water 30-35 ºC and sink in cool water! Using both rods will enhance your ability to make density... AP6489 - $24.55

Reduce your density lab costs with this economical set of four metal cubes. Students measure the densities of the four metal blocks and then determine their composition. This simple kit is effective at teaching density and is a great value! One-inch... AP7204 - $63.50

Challenge students to determine the composition of 15 colorful, different-sized rods, each one a different material. Students exercise their measurement skills with mass, length, and volume determinations as they problem solve to identify each material.... AP4615 - $12.90

A gallon of milk seems to weigh more than the fluffy pillow you sleep on. You probably wouldn't confuse these two materials nor have trouble thinking about their density. But how about steel versus iron? Aluminum versus tin? Density is a very measurable... AP4636 - $11.95

Mass, volume, and density are concepts you teach over and over again during the school year in many different ways. Help students understand the relationships between mass, volume and density with our Equal Mass Kit. Five cylindrical objects, made... AP6147 - $128.70

Wire with a memory! Nitinol wire was discovered in 1961 and has “shape” memory. When placed in cold water it can be bent into any shape. Put into hot water, it springs back to its original shape. Shape memory alloys are discussed in the Chem Fax provided.... AP4626 - $10.70

Seamless aluminum catch bucket to accompany our overflow cans. The flared lip makes total displacement water collection easier and the convenient handle makes pouring more controlled. Overall dimensions are 7.5 cm in diameter, 7.0 cm high, with a capacity... AP4627 - $12.20

The large sizes of our overflow cans make them especially useful for student experiments with density cylinders and Archimedes' Principle devices. The specially angled spout assures complete collection of displaced water thus providing greater accuracy... AP6301 - $21.60

What does pressure feel like? In this activity, students hold a small steel ball in one hand and a large foam ball in the other to answer the question-which one is heavier? Students quickly conclude that the small steel ball is heavier. However, when... AP7222 - $12.95
