AP7169 - $50.50
Don't just give your students the definition and equation for density—let them discover the concept for themselves! Using either “gold” or “silver” metal shot, students collect mass and volume data, plot the data on a graph to identify the resulting...
AP6649 - $17.20
A free-flowing U-shaped tube contains what appears to be a homogenous blue liquid, yet the liquid levels in the sides of the tube are unequal. No tricks involved—just density! This simple demonstration is guaranteed to heighten student interest on...
AP6928 - $51.00
Molecules can't be seen, but we can see the forces between molecules. Use this set of four demonstrations to show students what happens when molecules attract each other—or don't! • Floating Oil Droplet The difference in densities of water and ethyl...
AP7046 - $34.00
Is it possible to pour a gas? Set up the specially designed ramp with equally spaced candles. Add a clear liquid to the beaker, hold the beaker at the top of the ramp, and pour the invisible contents. One by one the candles are snuffed out! The beaker...
AP5939 - $81.15
Give your students a challenge—the measurement challenge! With this innovative teacher-designed kit, students learn to make accurate measurements, estimate to the proper level of certainty, and apply rules for significant figures in calculations. Hands-on,...
AP6153 - $28.60
Density—it's one of the first topics taught in every science class! Why spend time scrounging up density materials for a hands-on lab when you can have them ready to go in a moment's notice? This economical lab kit provides a complete introduction...
AP6268 - $73.45
Dmitri Mendeleev was not the first scientist to recognize relationships among the elements and classify them into groups. He was, however, the first to predict the existence and properties of missing elements. Introduce students to the periodic table...
AP7044 - $30.70
Just how thick is molasses? Density and specific gravity of liquids are determined with an instrument called a hydrometer. In this experiment, students construct a hydrometer and calibrate it using liquids with known density or specific gravity values....
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
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...
AP6148 - $142.60

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...
AP7995 - $39.75
AP Physics 2, Big Ideas 1 & 3, Investigation 1An object held in air feels heavier than the same object held under water. Physical laws dictate that matter cannot be created nor destroyed, so what accounts for the apparent weight loss? Through careful...
