There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

Second of six lessons in a unit on dissolving, this one focuses on how sugar behaves in different liquids. Learners stir it into water, alcohol, and oil and make observations. This lesson plan can stand alone, but is best used as part of...

Learners will like making a liquid layer cake to investigate the relative densities of various liquids: water, oil, and corn syrup. They will also introduce a few solid materials to find out how their densities compare. Standing alone,...

Don't be so dense that light bends around you; study the relationship between mass and volume instead. Young chemists measure the density of a variety of liquids and solids. A reading passage and analysis questions introduce pupils to...

From gas to liquid condensation to solid frost, water undergoes phase changes before students' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

There's a container for every matter—liquid, solid, and gas. Pupils design three different containers, each with the capability to hold one of the states of matter, and share their design with the class.     

Explore the concept of density within states of matter—gases, liquids, and solids—through a group experiment in which young scientists test objects' texture, color, weight, size, and ability to sink or float.    

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

Not many youngsters realize that solids aren't the only materials that can possibly be dissolved in water. During this investigation, they find out that some liquids can dissolve in water as well. This is part of a unit on solubility,...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...

Super scientists visit ten stations to predict, observe, and draw conclusions about the physical and chemical changes that occur when different states of matter—liquid, solid, and gas—are placed under a variety of conditions. To...

Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.

Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Titration experiments don't have to give your high schoolers a stomachache. Study the ways to titrate an acide with a base in an engaging science experiment, which involves creating solutions and performing titrations. Pupils...

What has more energy than a room full of pupils after a fire drill? This lesson plan! Explore the changes in energy during different chemical reactions, discover why some reactions feel cold and others feel hot, and tackle the concept of...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

We taste with our taste buds, so why do flavors change when we have a stuffy nose? Scholars experiment with taste testing while holding their noses and then while smelling. They record their observations in pairs and come together to...

We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity.
