".2mL PCR tubes"

Designed to study and demonstrate Snell's Law of Refraction.

Demonstrate how the frictional force on an object depends on the surface, not mass.

Large capacity hydroponics starter sheets.

Density Cubes, Set of 4 Metals with Hooks, 1.26" (32 mm) sides.

Package of 100, 300 or 500 interlocking cubes in 10 standard colors. An activities booklet is included.

Make teaching diffusion easy. Exclusively from Ward's Science, we've pre-mixed, pre-poured, pre-measured and pre-cut these agar cubes to save you time and eliminate messy preparation in your lab. Just open the jar and begin using. Prepared to align with Ward's AP Biology Investigation 4: Diffusion and Osmosis, these cubes are also ideal for use on their own, or in any lab activity demonstrating the topic of diffusion. Agar cubes are prepared in three sizes (approximately 1cm, 2cm, and 3 cm). Phenolphthalein has been added to the cubes to exhibit a vivid fuchsia color during production and stored in a solution of sodium hydroxide. Just add an acid such as vinegar to demonstrate diffusion.

Gram Centimeter Plastic Cubes

Observe the density across different materials and sizes.

Made from tin with an element stamp, measures 2 cm(0.8") per side, perfect for density, specific gravity, and specific heat activities in classrooms and labs.

Density Cubes, Set of 6 Metals, 0.8" (20mm) sides.

Ideal for exploring force of friction.

Density Cubes, Set of 4 Metals with Hooks, 1.26" (32 mm) sides, lead free.

This cart has been tried and tested in primary classes across the country and the response has been incredible.

A steel cube, an aluminum cube and a rectangular aluminum slab have each been painted to conceal the identity of the metal. The steel and aluminum cubes have equal volume while the aluminum slab has greater volume. One plastic metric ruler is included with this set. For use with IPS textbook. Set of three.

WARNING: CHOKING HAZARD - Small parts. Not for children under 3 years.

High quality density cubes for the classroom.
