Curated OER
Solids
In this solids learning exercise, students explain why solids are more dense than other states of matter. Students compare ionic solids and covalent network solids. This learning exercise has 6 short answer questions.
Curated OER
Water and Ice
Students experiment with water and ice. In this states of matter lesson, students explore how water can change from a solid to a liquid and back again. They discuss and write about the results of the experiment in a science journal.
Curated OER
Solids, Liquids and Gases
Young scholars 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.
Curated OER
What State Are You?
Students identify three states of matter and recognize plasma as fourth state. They provide examples of matter that are classified in particular state and identify properties of each state of matter.

Ice Cream in a Bag
Students observe phase change of matter by making ice cream in bags. In this states of matter lesson, students work in pairs to churn their own ice cream in plastic bags. They make predictions about how long it will take for the milk to...

Changing State: Condensation
When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

Don't Be Too Flaky
Snow, ice, and water are all composed of H2O. Does that mean they all have the same volume? Discover the ways that the densities of these substances determine their volumes, and how they change based on their current states of...
Curated OER
Water and Ice
Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.
Curated OER
Water and Ice
Learners investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Learners record their observations as the state of the water changes.
Curated OER
Water 1: Water and Ice
Students investigate water in its solid and liquid form. In this states of matter instructional activity, students experiment to see what happens as water goes from a solid, ice, to a liquid, water, and back again. They write about and...

What's the Matter?
First graders identify solids, liquids, and gases. In this matter lesson plan, the teacher guides students through numerous demonstrations as they determine the properties of solids, liquids, and gases and classify things as each. As...
Curated OER
Solids and Liquids
Learners investigate what happens to solids and liquids when they change from one form to another. In this states of matter instructional activity, students work in groups on a virtual experiment that requires them to collect data...
Curated OER
Gases Around Us
Students investigate gases and liquids. In this states of matter online lesson, students examine how evaporation plays a part in the transition of liquids into gases as they watch a kettle of water boil and then work in small groups on...
Curated OER
Water and Ice
Students explore water as it changes states of matter. In this physical property activity, students use observation, measurement, and communication skills to describe changes in water as it goes from a solid to a liquid and back again.
Curated OER
Outrageous Ooze
Students examine states of matter. In this solids and liquids lesson, students conduct a scientific investigation that requires them to make ooze and record their observations pertaining to it.
Curated OER
Oobleck
Young scholars examine states of matter. In this solids and liquids lesson, students conduct a scientific investigation that requires them to make oobleck and record their observations pertaining to it.
