This informational text discusses the unique property of ice - that it floats in liquid water. Students focus on real-world examples and how ice is necessary for life in the polar regions. The text is written at a kindergarten through grade one reading level. This version is a full-color PDF that can be printed, cut and folded to form a book. Each book contains color photographs and illustrations.

Flowering plants keep the world cooler and wetter than it would be otherwise.

In this lab activity, students will investigate the law of conservation of mass by weighing chewing gum before and after it is chewed.

In this lesson, we focus on what matter is. Matter has a formal science definition as anything that has mass and takes up space (or has volume). This lesson covers matter, mass, and volume in some depth.

In this activity students apply what they have learned about weighted averages, isotopes, and systems of equations to a new situation...coins in a sealed container. They learn some historical information regarding the composition of pennies and then are faced with a challenge: to determine the number of pre-1982 and post-1982 pennies that are contained in a sealed container without opening the container. After they determine the number of each type of penny contained in their canister, they will be asked to compare the pennies to isotopes.

This resource accompanies our Rethink Kindergarten Science Matter unit. 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.

This resource supports the English language development of English language learners. This book provides different examples of the different forms of water, liquid, solid, and gas, with pictures.

In this lesson, students use direct observations and computer simulations to understand that heat is the transfer of thermal energy.

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

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.

This is lesson one of the unit Weather Trackers (http://www.beaconlearningcenter.com/unitplan/11468.htm). Students learn by observation and hands-on activities the act of water changing state from a solid to a liquid to a gas.

The purpose of this lesson is to help students understand the relationship between the mass and the weight of an object. Students will study the properties of common materials and why airplanes use specific materials.

This chapter from the online textbook Everything Science discusses classification of matter and outlines the differences between elements, compounds, and mixtures. Each chapter comes with video lessons and explanations which help bring the ideas and concepts to life.

In this lesson students will understand radio waves and how they relate to the electromagnetic spectrum. They will determine wavelength, frequency, and speed of radio waves and master these concepts by completing example problems.

This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 2nd Grade Science.

In this video, students learn that all matter can exist in three forms: solid, liquid or gas. They compare the basic properties. Matter can change states through heating or cooling, and it is sure to change when it reaches its boiling point or freezing point.

This activity is intended to introduce students to the difference between physical and chemical changes in matter. Students will investigate the interactions of antacid tablets, water, vinegar, and bromphenol blue indicator to investigate changes in matter; observations will be recorded on a provided note sheet. Several ideas for assessment are also included.

In this activity, students will predict what will happen when two solutions are combined, and make observations about the properties of the new substance. Note: The teacher prepares the solution prior to the activity.

The students will be able to identify questions and concepts that guide scientific investigations, recognize and analyze alternative explanations and models by the end of this activity.

The purpose of this resource is to investigate the idea that every dynamic system has energy and matter in different forms.
