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.

Students formulate a hypothesis using critical thinking skills. They use an orange to examine the displacement of water as the orange sinks or floats.

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.

Learners construct their own submarine following a certain procedure. In this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.

In this density worksheet, students answer 12 questions about the density of substances. They read a diagram of a graduated cylinder and determine the volume, mass of water. They interpret a diagram with three liquids and indicated their...

Students examine whether objects will sink or float.  In this buoyancy lesson plan students bring in objects and experiment to see if they sink or float.

Students build a miniature replica of the Mayflower. They make the boat float in a cup of water while studying the concept of gift giving on Feast Day.

Learners investigate prime and composite numbers. They use a number chart and cross out multiples of 2,3,5 etc. up to 100. Pupils fold pieces of masking tape around pennies and label them with composite numbers, then fold masking tape...

Some microbes are beneficial for humans. This resource asks learners to identify beverages that contain healthy microbes. There are six beverages shown, and pupils must place a check mark next to the ones they think contain healthy...

Students explore the concept of environmental stewardship. In this science lesson, students examine the environmental effects of oil spills as they replicate a contained oil spill and clean up.

In this Archimedes' principle instructional activity, high schoolers answer 13 questions about the concepts of Archimedes' principle such as water displacement, buoyancy and force. The answer questions from a lab they did in class to...

Although this is a science lesson, it can be adapted to help meet Common Core standards in math as well. Starting scientists describe physical properties of objects and explore three forms of water. To address the Common Core, they can...

Students explore animal and plant adaptation.  In this ecosystems science lesson, students view websites to gain information about plankton and its  interdependence within ecosystems. Students identify ways in which plankton...

Students comprehend that Carbon dioxide gas is relatively easy to generate. They comprehend that one way to produce it is with dry ice. Pupils comprehend that carbon dioxide gas can also be produced by combining baking soda with vinegar.

Save the soup! Scholars devise a flotation device using straws, balloons, foam, corks, and other objects. A can of soup must stay afloat for at least a minute with this device—your dinner might depend on it!

What do we do when a dive is too dangerous for humans to accomplish? Send in the robots! Middle school scientists get acquainted with several different models of submersible robots in the second lesson of six from NOAA. Lab groups then...

First graders investigate the changing states of water.

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Students explore water, molecules, and surface tension. For this floatation lesson, students discover why some objects are able to float on water as they follow the procedures included in this activity.

Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.

Learners 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 discover how seeds travel from their parent plants in search of water, sunlight, and nutrients, and conduct experiments in which they note characteristics that encourage seed dispersal by means of wind, water, animal carriers,...

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

In this forces in fluids worksheet, students identify the principles behind the forces acting upon objects in fluids that make them float, lift and spray.
