Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.
Learners see that a carrot slice sinks in fresh water and floats in saltwater.
Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.
In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.
In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.
In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.
Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.
The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.
In this activity, learners use simple materials to create giant bubbles.
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.
In this math lesson, learners analyze the density of liquids in order to explore linear functions.
Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.
In this math lesson, learners explore polynomial and rational function patterns.
In this activity, learners measure and calculate the amount of cubic feet various containers contain. Next, learners investigate cubic feet per second (cps), by carrying jugs in one second.
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.
In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.
In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.
