Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Students experiment with the visocosity of corn syrup, mineral oil, vegetable oil, water, and honey. They research viscosity before beginning. Pupils draw the conclusion that the marble sinks more slowly in the liquids with greater...

Junior chemists manufacture biodiesel in the lab. In this exercise, they check the purity of the biodiesel using thin layer chromatography. They also calculate its density and heat of combustion. They are sure to rise to the...

Students calculate the volume of a specific mass of water placed in selected pieces of common laboratory glassware, using the density formula. They then determine the accuracy of the volumetric measurement for selected pieces of...

Second graders identify the three states of matter by examining fishbowls with various contents. They discuss their observations and the characteristics of matter in each state. Pupils read the story The Rainbow Fish and look for...

Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

Students calculate the density of regular and irregular solids and liquids. They relate the term dense to science as well as its literal meaning that society uses it as everyday. A worksheet is completed on density.

Students observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

Students comprehend that hot water rises up through cold water but cold water does not rixe in hot water. They comprehend that water at temperatures above 4oC decreases in density with increases in temperature. Students answer lab...

Students apply knowledge about density of solids from previous experimentation to this activity which they investigate the density of liquids. They work in small groups to mix water and syrup, and water and oil to see what occurs....

Students investigate the relationship between volume and mass in different liquids such as vegetable oil, rubbing alcohol and water. They measure the mass of several different volumes of each liquid and then graph the results as well as...

Young scholars observe experiments in density and describe the results. In the experiment, milk, corn syrup, and oil are added in different orders to three glasses, while one other glass contains only water. As objects are dropped into...

Students consider density and how it affects sinking and floating. Students make predictions, test liquids, and observe why some liquids sink and others float. They perform experiments to determine relational causality and how liquids...

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.

Students explore the causes of differences in density. Students choose objects, measure the mass and volume, and calculate the density of each. They perform additional density experiments to model atoms and their correspondence to...

Second graders watch a demonstration and complete an experiment to determine how an objects' density allows it to float or sink. They work in small groups to assimilate the characteristics of items that float as opposed to simply...

Students explore density. In this science lesson plan, students gain an understanding of the concept of density, especially as it relates to liquid. Students demonstrate that a less dense liquid will float on a denser liquid and that...

Students experiment to find which liquids are more dense.  For 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 physical science by conducting an in-class experiment. In this density instructional activity, students define vocabulary terms dealing with physics and discuss their knowledge of density. Students conduct several "sink...

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

Huygens spacecraft landed on Saturn's moon Titan in 2005, making it the farthest landing from Earth ever made by a spacecraft. In this hands-on activity, the 12th installment of 22, groups explore how density affects speed. To do this,...

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

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