First graders examine the water cycle through readings and experiments. In groups, they conduct interviews with others and use the information to create a chart displaying the various uses of water. After brainstorming lists of ways to...

Learners explore the concept of density and buoyancy. In this physics lesson plan, students discover the different factors that affect an object's density and buoyancy in water. Learners conduct several investigations to further...

Students use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Young scholars 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...

Middle schoolers examine why some objects float while others do not. They place various objects in water to observe their floating capability. Students record the object, its weight, and if the object floated. They construct a graph...

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.

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...

First graders develop skills of scientific inquiry. They determine which objects float and which sink.

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.

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.

Young scholars explore rotating frames of reference, focusing on the weightless environment in space and the Coriolis force.

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.

In this density instructional activity, learners explore an internet program called Gizmo where they do an experiment with density. Students complete 18 questions.

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..

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.

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...

Fourth graders discuss density.  In this floating golf ball lesson students complete a lab activity on density while working in groups. 

Students design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

Students calculate the densities of several liquids that appear similar.  In this physical science lesson, students go beyond understanding the way liquids of different densities behave to researching how this knowledge applies in...

In this buoyancy worksheet, students read about neutral buoyancy and that the downward force of gravity is equal and opposite to the upward force of water. They answer four critical thinking questions about buoyancy.

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

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

Students understand the properties of Bamboo and what it can be used for. In this bamboo lesson, students with bamboo and compare and contrast to wood. Students share their findings.
