Begin with an introduction to famous deep-sea submersibles. Learners work in groups to gather information on different vessels and then share with the class. Each group then uses water displacement to help calculate the density of...

Learners examine the flow of water. They observe and test the properties of water by using sticks in flowing water. The lesson has streaming video, resource links to access, and a good hands-on activity that is clearly described in the...

Properties in measurement, pressure and viscosity of solids, liquids, and gases are the main topics covered in this slideshow. The explanations of Pascal's, Bernoulli's, and the Venturi effects are very clear. Easy to understand diagrams...

Match animals to their environments with a cute lab activity. Kids draw a line between each animal, such as a fish, a rabbit, and an ant, to the place where it lives. For hands-on practice, a science investigation instructs learners to...

Fifth graders complete a instructional activity which has them place a list of gases in order from the least to the most dense. The density in grams is given for each. There's a good paragraph which provides background knowledge about...

Whatever floats your boat—with some additional weight. The first activity in a five-part series challenges pupils to design a boat to hold pennies. Using the design process, learners design, build, and test their boats, making sure they...

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.

Middle schoolers 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...

Students experiment with water density, temperature and salinity. In this water lesson plan, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

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

Young scholars investigate the density of liquids. For this geometry lesson, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.

Learners perform experiments to examine if debris float, or blow in the wind. The effects of these characteristics on the marine debris are then discussed. They determine how a material can influence what becomes marine debris.

Now is the time to educate tomorrow's citizens to care for the planet, and here is a lesson to help facilitate the process. Collect some marine debris and bring it into class. Have your class separate it into types and then test each...

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..

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...

Students define density in their own words. In this physics instructional activity, students calculate density using mass and volume. They explain why some objects sink and some float.

Students 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...

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.

Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.

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

Students identify and interpret the lifecycle and parts of the pumpkin. Students utitlize interactive ways to discover this process. Students create a big book of their own by researching further information about pumpkins and what...

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.

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.
