This lab activity does not have to be done with AP environmental scientists. It can also be done with middle to high school earth scientists. The procedures aren't complex. Learners determine the density of dry and wet sand in order to...

As the title implies, this is a list of vocabulary terms relating to water monitoring. If your ecology class is learning about how to test water quality, this will be an appropriate reference sheet for them. As a bonus, if you live in...

In this density activity, students review the equation for density and are given a chart of the densities of various substances. They solve four problems finding the densities of substances and identifying unknown substances given the...

Clay's as good a material as any to build a boat, right? An introductory activity sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

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...

How can you relate colligative properties of solutions to everyday situations? Pupils first discuss the concepts of density, boiling and freezing points, then demonstrate how to accurately determine the boiling and freezing point of...

Don't be so dense! Using food coloring, pupils conduct two experiments with the difference in densities of hot and cold water. In the first experiment, learners add dyed hot and cold water into room temperature water and observe how the...

Here is a planet activity in which learners read about organic molecules detected through spectral lines of the planet Osiris. They calculate the mass, the volume and the densities of common ingredients for planets including Osiris and...

Hydrogen bonds, and polarity are described in this PowerPoint, and the reasons for tension and cohesion associated with water.  The states of water under certain conditions are explained with information about the changes in...

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

Students observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the density...

In this density worksheet, high schoolers answer 12 questions about the density of substances. They read a diagram of a graduated cylinder and determine the volume, mass of water. They interpret a diagram with three liquids and indicated...

Students explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

In this density demonstration, students compare a can of diet coke to a can of regular coke. They list the similarities and differences of each prior to the demonstration. The cans are placed in a tank of water and students record their...

Students find the mass, volume, and density of various objects. In this density measurement lesson, students observe how same-sized objects can have different masses, then use water displacement to find the density of each object and...

Learners learn how to measure the density of metals. In this density of metals lesson plan, students measure the density of various metals in order to determine what metals were substituted in a king's crown, scepter, breast plate and...

Sixth graders explore the concept of density as a relationship of an object's mass to its volume. Densities of a variety of objects are compared and used to identify an unknown object.

In this density graph worksheet, middle schoolers graph data displayed in a chart. Students also calculate the density of each metal shown in the graph. Middle schoolers answer questions about which detail is more dense.

Students investigate the properties of matter. For this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...

Students use density to identify what metal a gold colored weight is made of. They use a spreadsheet to graph the experimental density of common metals and compare the know densities to their calculated density of the known metal.

Learners study the water cycle and how the sun is an important factor.  In this water cycle lesson students investigate how to desalinate water and explore the different densities of fresh versus saltwater.

In this moon instructional activity, students read about the data collected from the Deep Impact/EPOXI and Cassini missions to the moon that have detected the presence of hydroxyl molecules under the moon's polar craters. Students solve...

The first golf balls were made of wood and would only last for a few games. Modern golf balls last a lot longer but they don't float. The presentation provides the directions for a lab to determine the minimum amount of salt needed to...

Use the classic density demonstration of placing a cola, a clear soda, and a diet soda into a tank of water. Then let learners attempt to pour some of the soda into layers in a clear container. The procedure explains a thermocline, and...
