Designing and Floating Boats
Students participate in an experiment to determine if a toy boat will sink or float. They make the boats out of different materials and determine its carrying capacity by adding pennies. They graph their findings on a classroom graph.

Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. In this water activity, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Float My Boat
Fourth graders, in groups, experiment with density and the displacement of water by creating and designing their own boats and seeing which boat holds the most centimeter cubes without sinking..
Curated OER
Weight in Water
Students investigate why some materials are able to float while others sink. They carry out a scientific investigation, predict and test their predictions. They record their results in a spreadsheet, and use a forcemeter in another...

What Floats Your Boat?
Learners discover the Archimedes principle through a buoyancy experiment. They measure the water displacement of a lump a clay which is denser than water then reshape the clay into a bowl which floats but displaces more water.

To Float or Not to Float - A Lesson on Density
Learners define density in their own words. In this physics lesson, students calculate density using mass and volume. They explain why some objects sink and some float.
Curated OER
Science Lesson #2
Fourth graders explore and experiment with objects that float to see if they float differently in salt water or fresh water. After the experiment, they write a paragraph in their science journal explaining how fresh water and ocean water...
Curated OER
Floaters and Sinkers
Fifth graders define density as the amount of mass per volume a material contains, compare the densities of several types of materials, especially those that sink in water compared to those that float. They use two different methods to...
Curated OER
Science: Water States
First graders investigate the various forms of water. They discuss the properties of water. They discover examples of water's various states and locate other solids, liquids, and gases in their homes.
Curated OER
Atoms, Kinetic Theory, Solids and Fluids
Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.
