Students research the process of fractional distillation. In this chemistry lesson, students perform simple distillation of two liquids. They collect data and share results in class.

Learners examine buoyancy.  In this density lesson students form a hypothesis, collect data and draw a conclusion using the data. 

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

In this density laboratory learning exercise, students complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

For this Cartesian diver lab, learners explain using text and diagrams how the Cartesian diver works. Students evaluate ways in making their lab design better. Learners make predictions of how changing the variable would change the...

In this chemistry review worksheet, learners review terms and concepts covered. Students practice metric conversions, factor labeling, temperature conversions, heat calculations, atomic structure, and gas laws. This worksheet has 3...

In this water worksheet, students review the properties of water including the density, boiling point, and evaporation. Students define mixture, solute, and solvent. This worksheet has 22 short answer questions.

In this 9th grade science review worksheet, students complete 63 true or false questions on topics such as atomic notation, isotopes, covalent bonds, Ohm's law, and electric circuits.

In this matter worksheet, students complete a data table by comparing the physical properties of 7 different samples of matter. This worksheet is a graphic organizer.

In this biology learning exercise, students use the website given to become familiar with the equipment of a lab. The activity involves a link to a virtual laboratory. Then they determine an objects mass and volume by placing it in a...

Learners 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 each...

Students explore the concept of density. They use the the formula Density = Mass/Volume, one can determine where certain liquids and objects will settle in a graduated cylinder. In addiiton, they design a process to separate the liquids.

Students investigate how a population of fish multiplies in an ecosystem and the kinds of things that must be done to maintain a healthy population balance with other organisms that live there. They conduct an experiment to test the...

Students use graph paper to construct a graph and determine the slope of a straight line. They determine the weight (mass) of paper clips with a pan balance. Pupils weigh an unknown number of paper clips, and to interpret the graph to...

Students comprehend that density depends on the type of material and not on the amount of material. They use a spoonfl of table salt and a box of table salt and have the same density. Pupils comprehend that density is calculated by...

Young scholars view a video which introduces them to density and the states of matter. They experiment, collect data, and graph the boiling/freezing points of several edible items...and then make brownies!

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 how density changes. Students read an article on density. They observe a ball and ring demonstration and discuss the outcome. Students draw models of the demonstration and explain what happened.

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 explore what causes differences in density. They observe an models depecting atoms, compounds, and molecules. Students determine if there is air in between atomic bonds. They study the structure and spacing of molecular bonds.

Young scholars 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...

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...

Students discover that density is considered a property and that cutting an object in half does not affect its density. They examine the densities of many common substances and make connections.

Learners investigate density and its relationship to air and gas. Students perform experiments to determine if gases have mass. They explore possible ways to figure out the density of gases.
