Used to simulate effect of earth's rotation on winds, ocean currents or unattached objects such as rockets. As sphere is launched across surface of base, when it is static, sphere traces a straight line. As turntable is put in motion, centrifugal force launches the sphere which, though traveling in a straight line, leaves a curved trace on rotating surface. Size of curve is in direct ratio to speed of rotation. Each kit includes one 14" diam. base (with outer retaining trough) mounted on a turntable, and featuring a reusable "magic slate" type erasable trace recording surface, removable launcher, 5/8" diameter steel spheres.

Demonstrate the parts of a flower in plant science lessons with this durable foam tulip model. One half of cross-section is labeled with part names (stamen, petal, pistil, sepal, stem, leaf and roots); other half is labeled with letters for assessment activities. For more detailed study, Activity Guide features discussion and labeled drawing of additional flower parts, including filament, anthers, stigma, style and ovary. Foam model wipes clean and measures approximately 6" H. Ages 7-11.
This model of a plant cell splits in half to provide a cross-section view and make learning the parts of a plant cell easy. One half of the colorful foam model is labeled with the parts of the cell, and the other is labeled with letters only. Included Activity Guide provides detailed information on plant cells. Ages 7-11.
Using the Crucible Cradle will help alleviate many of the problems associated with the proper handling of the crucible. You can now eliminate the need for the use of crucible tongs. Many students find the use of tongs awkward and end up dropping the crucible. The Cradle will also eliminate the need to touch the crucible after it has been heated. Oils from the finger tips can add weight to your final results, and throw off your findings.

Cupric Sulfate reagent fine crystal - 125g
Cupric sulfate (copper(II) sulfate) reagent fine crystals are widely used in classrooms for chemistry experiments and demonstrations, primarily due to their distinct blue color and diverse chemical properties. Common educational uses include:
-
Chemical Reactions and Color Changes: Cupric sulfate is often used in experiments to demonstrate various chemical reactions, such as double displacement reactions and redox reactions. For example, when zinc metal is placed in a solution of cupric sulfate, a redox reaction occurs, producing copper metal and zinc sulfate.
-
Electrolysis and Electroplating: Cupric sulfate is commonly used in electrochemistry experiments to demonstrate the principles of electrolysis. Students can use it to deposit a layer of copper on a metal object, illustrating the concept of metal plating.
-
Crystallization and Hydration Studies: Cupric sulfate crystals are ideal for studying crystallization and hydration. In its hydrated form (CuSO₄•5H₂O), it is a vibrant blue, but it turns white upon heating when it loses its water molecules. This change is used to teach about the effects of hydration and dehydration on compounds.
-
Identifying Presence of Water: Cupric sulfate can also be used as a qualitative test for water. The blue hydrated form turns white when heated (as it becomes anhydrous), and when a drop of water is added to the anhydrous form, it turns blue again. This makes it an excellent tool for illustrating reversible hydration reactions.
-
Demonstrating Copper Ion Properties: The distinct blue color of cupric sulfate is due to the presence of copper(II) ions in solution. It is often used to teach students about the behavior of transition metals and their unique colors in aqueous solutions.
Cupric sulfate should be handled carefully, as it is toxic if ingested and can cause irritation to skin and eyes. Proper safety equipment, including gloves and goggles, should be used during experiments.
