The Density of Liquids and Solids
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,...
Curated OER
Solids, Liquids, and Gases
Not many lessons on states of matter can hold a candle to this one! Junior chemists gauge the density of paraffin in both liquid and solid phases. They fill 60 mL syringes with different materials to experiment with compressibility and...

From Gas to Liquid to Solid
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...
Curated OER
Gases, Liquids and Solids, evaporate, shape volume,
Students conduct an online experiment to discover what happens to solids, liquids and gases in different temperatures. In this states of matter lesson, students get into pairs and work in a virtual laboratory to manipulate...

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.
Curated OER
Sometimes, solid + liquid = gas
Third graders experiment with common household liquids and solids. In this chemical reaction lesson, 3rd graders discuss phase changes and experiment to find other ways to create gases. They use water, vinegar, lemon juice, flour, baking...
Curated OER
Solids, Liquids and Gases
Students 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 gases and...
Curated OER
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.

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.
Curated OER
What Is the Matter?
Students explore and identify phases of matter and compare the particle motion in solids, liquids, and gasses.
Curated OER
Solids, Liquids and Gases
Students explore solids, liquids, and gases. In this states of water lesson, students conduct a scientific investigation that requires them to observe and note the differences among solid, liquids, and gases.
