Causal Patterns in Density Phenomena

Oceanography observers keep current on how currents form in the ocean. In this demonstration, they will see how denser water, whether it is caused by the addition of salt or cooling of temperature, sinks. The title of the handout...

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

Why are the properties of the water important when exploring the ocean? Young scientists discover the tools and technology used in deep sea exploration in the fourth installment in a five-part series. Groups work together to examine...

The phenomena observed in the behavior of waves and data received from seismographs can lead us to various conclusions about the densities of material that waves are passing through.

Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...

Students investigate the effects of differences in air pressure on a system. They answer the question, "What makes a liquid go up a straw when you suck on it?".

Students investigate the concept of density by observing demonstrations. In this density lesson plan, students make observations while the teacher demonstrates the Cartesian diver, a density column, a candle trough, a wave bottle, an...

Students explore lift and Bernoulli's Principle using a relational causal model. Using paper and straws, they investigate lift and relate Bernoulli's Principle to everday occurences.

Students define density as a relationship. Through experimentation, they explore the association between the mass and volume of pure substances. Students create a data plot and analyze the patterns between mass and volume. Students...

Andree Walker thought of everything when he wrote this resource. It includes a detailed list of materials and background information links for the teacher. In addition, it has procedures, a macroinvertebrate identification key, and tally...
