Science learners simulate what happens when ice breaks up and floats on water and how increased pressure on ice causes it to melt faster. They view a clip from the movie, The Day After Tomorrow, and relate their lab activities to what...

Learners investigate how changing pressure affects density. In this physics lesson, students explain the relationship between density and pressure. They observe the Cartesian diver in the lab as pressure is changed inside.

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Young scholars relate the concept of density in relation to the rocks that make up the Earth. They determine the density of various rock specimens and answer assessment questions.

Students participate in Density Discoveries, which is a hands-on learning opportunity for students to find the mass, volume, and density of solid matter.

Students use scientific measuring tools to collect and use scientific data. They determine the density of four different objects by using their data to explain why objects have similar/different densities even though they are both made...

High schoolers observe a demonstration of regular soda versus diet soda.  In this exploring density instructional activity students complete a lab on density and present a PowerPoint presentations of their results.

Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Students use the scientific method to conduct an experiment and use varied methods to gather background information. They correctly use lab equipment and prepare tables and graphs that organize, conclude, and present their findings. ...

Students explore the density of liquids. In this scientific inquiry lesson plan, students discover the density of water, corn syrup, and cooking oil through an experiment. In addition, students will draw and label pictures of the...

Students determine the density of Plaster of Paris that has been prepared with a foam generated from dishwashing liquids and shampoo.

Young scholars draw upon their prior knowledge of the density of water and practice writing a hypothesis, making an observation, and analyzing data while watching a density demonstration.

Learners have the opportunity to observe, measure and analyze the density of aerosol shaving creams and foams generated from shampoo and dishwashing liquids or detergents.

This open-ended boat building exercise is meant to be part of a three-instructional activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat,...

This lab activity is geared toward experienced chemistry learners, in particular, those who are familiar with organic chemistry. They will create a synthetic elastomer  and then make observations and measurements of its different...

Science rocks! Explore three types of rocks and the rock cycle with an igneous rocks experiment. Pupils discuss textures, composition, and learn how melts are formed from the Earth's crust. They weigh materials using a scientific scale...

Young scholars participate in a discussion of volume and density and then engage in a hands on lab. They weigh equal volume cubes at lab stations of an assortment of common substances in a lab setting and record data on their findings on...

Students observe fluid motion. For this Physics lesson, students explore the principles of Pascal, Archimedes, and Bernoulli. Students list their experiences with fluid movement.

Note that this lesson is best paired with the preceding lesson in the unit. In that lesson, elementary physical scientists observed that the color coating of M&Ms® candies do not mix when dissolved off of the chocolate surface. Now...

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 instructional activity of six from NOAA....

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

Young scholars are introduced to the periodic table of elements. They devise and perform and experiment in which they determine the density of specific elements. They use their results to predict the density of other elements in the same...

Students determine the density and thickness of a piece of aluminum foil. In this density and thickness of materials lesson plan, students experimentally find the density of a piece of aluminum foil and compare it to the theoretical...
