Students must design and conduct an experiment to determine which unknown liquid has a greater density based on basic information about the liquids and containers. Students are given specific materials to work with.

Learners receive a miniature pumpkin and proceed through several stations to measure a variety of physical properties. The data is entered into a data sheet and the mass and volume measurements are used to calculate density. They also...

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

Students investigate density. For this density lesson, students conduct an experiment using food coloring. Students observe the differences in mixing food coloring in water and oil.

Students investigate several unidentified substances and suggest a use of each substance. They can explain that a substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of...

Students follow directions for a simple chemical experiment. They use the appropriate tools and techniques to gather, analyze, and interpret data. Students identify a substance that has characteristic properties, such as density, a...

Students conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...

Young scholars examine how trees are measured and the different methods used.  In this density instructional activity young scholars divide into groups and practice the different methods.

Students experiment with different salinities of water using straws and different colors of water. They collect and interpret data from the experiment.

Have your class predict whether objects will sink or float in water. Learners consider a data table of mass, volume and whether the object sank or floated. They develop an evidence-based explanation for the results.

Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.

This open-ended boat building exercise is meant to be part of a three-lesson 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, find its load line...

This seventh grade life science quiz has a professional appearance and well-written multiple-choice questions. However, it seems to cover too broad a variety of biology topics for only 15 questions to fully assess. There is one question...

Middle schoolers acquire census information and create maps of the population density of the United States on different scales. They role play the roles of workers of a retail company and they use the population data to market to their...

Students study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.

Learners investigate how the density of water changes the buoyancy of water. Students create a hypothesis about what will happen when placing the egg into the water.Learners can research online different bodies of water (The Red Sea, The...

Students design a boat of aluminum foil and calculate the density of the boat. Washers are added to the boat until it sinks. Students then redesign boat to hold more washers and recalculate the new density.

Students investigate buoyancy by participating in a lab experiment. In this density lesson, students utilize vinegar and alcohol in beakers and attempt to float different items in them. Students analyze which items float and do not while...

Students 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!

Pupils consider the effects of temperature on water density. In this Earth Science lesson, students evaluate a demonstration of cold and hot water currents in a model. Pupils use two liter bottles and varied water temperatures with food...

Science, technology, and math come together in this one combination exercise. Analyzing the common soda can from both a purely mathematical perspective and a scientific angle allows for a surprisingly sophisticated comparison of...

How do astronauts know how to live and work in a weightless environment? It doesn't come naturally! Junior physicists conduct experiments to examine the link between buoyancy and microgravity. Each activity illustrates a different aspect...

Students investigate water column data. In this earth science and seawater lesson, students determine how temperature, salinity, and density have an impact on sea water by viewing and analyzing data obtained from a number of websites....

High schoolers observe demonstrations that show adhesion, cohesion, equilibrium density, pressure of gases and solubility. In this gases lesson plan, students observe a demonstration of raisins, spaghetti, and popcorn moving up and down...
