Investigating the Effect of Salinity on the Density and Stability of Water
Water with varying amounts of dissolved salt are dyed and then used to compare densities. The objective is to discover the effect of salinity, and therefore density, on ocean water on the stability of the ocean. Many branches of science...
Curated OER
Sink or Float
Students experiment with different objects to test if they sink or float. They predict what the object will do before it is put into the water. They are allowed to play with the items after the experiment is over.

Anthony's sink or float game
Students explore the concepts of float and sink by playing a game where they build things on mud, water, rock and jelly. In this Anthony's sink or float game lesson, students discover what materials remain strong in various conditions....
Curated OER
Water Exploration Station
Students explore the characteristics of water. In this water exploration instructional activity, students participate in various learning centers to inquire how water drains and how to increase the flow of water. Students use estimation...
Curated OER
Sink or Float
Students construct clay boats and predict whether the boats will sink or float. Students will hypothesize what caused the boats to sink or float.
Curated OER
Float and Sink
For this float or sink worksheet, 8th graders solve 1 science/math puzzle about displacement of water; the answer is available online.
Curated OER
Dragon Boats
Learners create a model boat. In this art lesson, students identify what makes a boat float and use milk cartons to create their own boat.
Exploratorium
Descartes' Diver
Pique interest in water pressure, demonstrate buoyancy, and explore water displacement concepts with a homemade Cartesian diver. You may want to change the name of the toy, however, as is is not documented the Rene Descartes...
Curated OER
Heavy Ice: Day Five
Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...
Curated OER
What's The Matter: A Sinker or Floater?
Students conduct an experiment. In this water lesson, students watch the lesson "Float and Sink" on an interactive website. Students learn how to test items in water and then work in groups to test their items. Students discuss their...
Curated OER
Stacking Water
Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.
Curated OER
Vegetable Olympic Swimming: Will it Float?
Students inspect nutrition by conducting a science experiment in class. In this vegetable identification lesson, students examine a group of different veggies and predict whether they will sink or float in a tub of water. Students check...
University of Waikato
Buoyancy in Water
Change where an object floats in water. Pupils experiment with a Cartesian diver by squeezing on the side of a plastic bottle. Learners pay attention to the bulb of the pipette as the bottle is squeezed to determine what is happening...

Sink or Float?
Young scholars analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Young scholars discuss the questions...
Curated OER
The Weight of Water
Students examine how salt water is more dense than fresh water. They discuss how manatees need to float and sink, conduct a sink or float experiment, and conduct an experiment with eggs and salt and fresh water.
Curated OER
The Role of Density in Sinking or Floating: Relational Causality
Students consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how liquids...
Curated OER
WHY DO SOME THINGS FLOAT WHILE OTHERS SINK
Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.
