Comparing the Density of Different Liquids
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,...

Comparing Solids, Liquids, and Gases
In this solids, liquids and gases worksheet, students observe a teacher demonstration about gases and they experiment with liquids to show diffusion, shape and volume. They answer nine questions about the experiments related to solids,...

Matter Matters: Solids, Liquids and Gases
Scientists participate in a variety of hands-on experiments in this ten-day unit on the three states of matter. Lessons incorporate literature, a-v materials, and poetry to help learners differentiate between solids, liquids and gases.

Solids, Liquids and Gases
Young scholars are introduced to the various states of matter. After watching a video, they discover how to compare the three states using its shape and volume. In groups, they participate in an experiment with solids, liquids and...

What Is the Matter?
Students explore and identify phases of matter and compare the particle motion in solids, liquids, and gasses.

Mystery Eggs
Students investigate the properties of plastic eggs filled with solids, liquids, and gases and use these observations to hypothesize whether a chicken egg is hard-boiled or raw.

Density: Sink and Float for Solids
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...

Heat Transfer and Heat Capacity
It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

Challenge with Solids, Liquids, and Gases
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.

Dissolving and Back Again
From solid to liquid and then back again. Young scientists dissolve salt in water and then evaporate the water while observing what happens to the solute. They use their observations to make predictions about other solutions.

The Liquid State
Due to surface tension, dew — a liquid, is spherical in shape. Learners explore the properties of liquids in activity seven in this series of 36. Beginning with its basic properties such as boiling point and moving through to surface...
Curated OER
Solids, Liquids, and Gases
Students investigate and explore the three states of matter. They read and discuss the NASA article "The Engine That Does More," identify examples of each state of matter, and as a class complete a section of two worksheets. They...

Density
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.

Constancy and Change
Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe what happens when they try to put two kinds of matter into the same space and conclude that solids, liquids, and gases occupy space.

Science- Unit on Matter- Solids
Second graders identify and describe properties of matter.
They identify three forms of matter- solids, liquids, and gases with 100% accuracy. The student describes the properties of solid objects.

Phases of Matter
Learners are introduced to the basic states of matter: solids, liquids and gases. Through experimentation, students determine that liquids and solids have definite volume, that gases do not have definite volume, and that solids have a...

Water Changes and Moves
Students explore the three forms of water and observe how it changes from a solid to a liquid to a gas. The concepts of condensation, evaporation and the introduction to the water cycle form the basis of this lesson.

Water: Liquid or Solid?
First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

Density Column Lab - Part 2
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...

Water and Ice
Students will observe, measure and describe the phase changes of ice. In this science lesson plan, students observe ice as it changes phases. Qualaitative notations made by individual students will be shared and compared.

Heat and Matter
Students explore liquids and solids by conducting in class experiments. In this matter lesson, students define the properties of matter and how heat can change those properties. Students experiment with heating objects such as butter and...
