After learning about the 3 States of Matter, students can be tested using a pop quiz to check for understanding of the subject, how they transfer from one state to another and also how they are able to illustrates the states of matter either through a drawing of a real life example of the state of matter or the state of matter as a particle. (3.P.2.1, 3.P.2.2, 3.P.2.3)

This parent guide supports parents in helping their child at home with the 3rd grade Science content.

This resource accompanies our Rethink 3rd Grade Science course. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning. 

Design a prototype of a solar oven given a cardboard box, ruler, pencil, scissors, aluminum foil, and plastic wrap. Test the oven to see if a s’more is able to cook inside of it.

In this activity, students are introduced to water and its three phases - solid, liquid, vapor. Students will use their senses to observe, taste, feel, and describe water, and their imaginations to understand the concepts of water's phases.

This is an introductory activity / lesson for a larger investigation into the properties of air. Students build a equal arm balance from simple materials to demonstrate that air has mass.

In this lesson, students will distinguish between solid, liquid,and gas in a simple demonstration where an effervescent tablet is added to water.

Students will observe properties and compare water in the 3 states of liquid, solid, and gas. Utilizing a triple Venn diagram to help deepen their understanding of matter. 

Students become aware that the majority of the Earth's surface is covered by water. They will also understand that water can exist in three states. Teacher Notes for the activity are in the database as a separate resource.

This article provides several simple, fun experiments for elementary students to investigate what happens to solids, liquids, and gases when they are heated.

Students will explore solids, liquids, and gases and record their observations and experiences in science notebooks.

This scientific article explains the historic, social, and economic implications of the invention of the steam engine. It also discusses how the industrial revolution made manufacturing plants independent from locations next to rivers. The last part describes the nostalgic use of historic steam engines. The text is in child-friendly language and appropriate for children age 8 and up.

In this lesson, students will observe the differences between solids, liquids and gases. They sort different liquids as to their physical properties. Finally, they observe how food coloring mixes in water, club soda, and salt water.

Students use water to explore its properties as a solid, liquid or gas.

In this unit, students explore the concept of matter as they work through a series of 8 hands-on lessons. Students investigate mass, volume, physical change and chemical change in this comprehensive unit. An assessment is included at the end of the unit, and teacher background information is also provided.

In this short unit, students are introduced to the three forms of matter by using their observation skills and recording properties of various common examples of matter. Students will work in pairs and small groups to observe, discuss, and record properties of solids, liquids, and gases. A poem about matter and a diagram of solid, liquid, and gas are included with the lesson.

In this lesson, students explore the properties of water and hypothesize how to cause changes from a solid and gas state to a liquid state. Students use their new science knowledge to have an ice cube melt race.

In this lesson, students will explore the properties of matter by mixing cornstarch and water to create a colloid. This activity can be done with or without the reading of Dr. Seuss's "Bartholomew and the Oobleck." The books goes very well with the activity and gives the students an idea behind the concept of the workd "oobleck."

In this activity, students investigate the three forms of matter. Students create a snow figure outdoors or as frozen ice in a mold. Students will make predictions as to how long it will take the snow/ice to melt and then test it. Students will then use clay to make models of water as frozen, melting, melted, and evaporated. Students will compare the models with their actual events.
