Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.

Eighth graders experiment with a number of dishwashing liquids to determine the duration of the bubbles. They graph the data, add glycerin to the dishsoap, and repeat the experiment. They graph and compare the data sets.

Fourth graders experiment with the viscosity of different liquids. They use a stopwatch to time the a steel ball as it drops through different liquids.

Students conduct an experiment on heat transfer and how it works. They record the temperature in whatever environment is surrounding the container and run experiments that use at least two different ambient temperatures. Students...

Students have seen that solids, which are more dense than a liquid, that sinks in that liquid and solids, which are less dense than a liquid, that floats on that liquid. They use a metal boat to float in water. Pupils comprehend that...

Students describe how diffusion occurs within a liquid. They explain a situation where diffusion through a liquid might occur in the natural world.

Young scholars investigate the changes that occur at the molecular level when a liquid becomes a solid. They freeze water in baby jars and observe the changes that occur in the process.

Learners design an experiment to determine which liquid is water. In this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.

Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

Students are told that objects in contact with one another reach an equilibrium temperature. A hot object placed in a cool liquid always cool off. It never happens that the object gets hotter and cool liquid gets colder. Students predict...

Students read and discuss the book about the butterfly and create their own butterflies using liquid watercolors and pipe cleaners. They then create a butterfly development book, included in the lesson, and color the pictures using...

Students create "Kitchen Fireworks." In this fireworks lesson, students pour milk into a baking pan and add food coloring. They squirt in dishwashing liquid which bursts the colors and swirls them. 

First graders make ice cream and determine what makes this liquid turn into a solid.

Students predict what is going to happen using prior knowledge being prepared to alter a view when faced with new evidence. They then accurately measure and record liquid volumes realizing that liquids and granular solids have...

Students review properties of matter and discuss how materials change when things are done to them. They observe how materials change as a reaction to temperature by following the procedure to make ice cream and recording the temperature...

Pupils test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict if...

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

Eighth graders determine the density using mass and volume. In this science lesson plan, 8th graders explain why some materials float or sink. They estimate the density of objects based on whether it floats or sinks in a liquid of...

Learners combine movement with science in this fun integrated instructional activity. When students are "liquid" they can "melt" or "ooze" at the end and when they are are "solids" they can "freeze" in a shape.

Second graders use knowledge of measurements and ratios to mix various combinations of liquid starch and glue. They chart their ratios, make observations, and write a summary of the activity. They mix their own batch of Crazy Putty to...

Pupils examine why air pressure is hard to notice. They observe the height of a liquid in a tube over time and lift a table with balloons.

Students investigate "indicator" (Bromothymol Blue or BTB) to test for the presence of certain chemicals in liquids and gases. They compare distilled water and seltzer water for presence of carbon dioxide.

Learners examine acceptable levels of toxins in swimming areas. Working in groups of four, students dilute a salt or sugar solution to 1 part per 1,000,000 (ppm) solution. Learners taste test their diluted liquids and record at which...

Ninth graders explore the abstract idea of the atom and explain the differences and similarities between solids, liquids, and gases. They understand the molecular differences between solids, liquids, and gases.
