Paper Clip Sailing
Students explain that some things can float on top of water because of what we call "surface tension." They see that if something happens to disturb these water molecules from tugging on each other, the skin-like surface breaks up.

Clay Boats
Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Sink or Float?
Students predict and explore to discover which objects sink or float in fresh and salt water, predict how salt affect objects, write predictions on T chart, discuss difference between man-made and natural waters, and graph results.
Curated OER
Density
Ninth graders predict when an object will sink or float based on comparison of the density of the object to the density of the substance in which it is placed.
Curated OER
Density Lab Activities
Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

Making Predictions
First graders write with his or her pencil on a worksheet created by the teacher his or her prediction of whether each part of a pumpkin will sink or float. They drop each of five objects in the water one at a time allowing enough time...
Curated OER
Mystery Canisters
In this density worksheet, students modify three film canisters in order to make one float in a tank of water, another suspend in the middle of the tank, and the third should sink to the bottom. They collect data on their canisters and...
Curated OER
Salinity
Learners define and discuss salinity, conduct classroom experiment to determine salinity of water sample by using hydrometer, record predictions, and demonstrate understanding of how salinity influences object's ability to float in water.
Curated OER
Density
In this density worksheet, students read a selection on density and answer 10 questions using the information from the selection.
