Second graders explore states of matter when they change a liquid to a solid. Working students make ice cream in a zip-lock bag.

Young scholars observe liquids in different containers and then explore the concept that liquids have level surfaces. They identify those who are not at the center to reinforce the concept of liquid levels with a representational puzzle...

Students investigate basic geometric concepts. In this geometry lesson, students explore solids through measuring and modeling. This assignment models the importance of understanding concrete objects in geometry.      

Students examine the rule of "like dissolves like." They define and describe solutions and solubility models on molecular liquids, ionic solids, and molecular solids.

Young scholars identify and sort a variety of two- and three-dimensional objects and compare and contrast their attributes. They identify shapes, locate shapes on the faces of solids, sort real objects and explain the sorting rule, and...

Students explore solid waste background information. They are presented with a well balanced picture. Students review ideas on how to use solid waste issues in many fields including math, science, English, social studies and home...

Students explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond....

Third graders gain appreciation of water by watching online video, "Weather Smart: The Water Cycle and Clouds," exploring how water cycle works, comparing and contrasting three states of water as solid, liquid, and gas, and discussing...

In this lab activity worksheet, students record the time it takes for an ice cube to melt in three different situations. After collecting data they design a container that will keep an ice cube in a solid state for as long as possible.

Students identify geometric solids. In this geometric shapes lesson, students listen to the teacher read Captain Invincible and the Space Shapes  by Stuart J. Murphy. Students then visit a web site where they identify types of...

Students rotate through various hands-on experiment stations to explore the concept and properties of different types of matter. They compare some properties of solids, liquids and gases and describe how matter changes from one state to...

Student designs a test that uses their sense of hearing to judge the effectiveness of different solids to transmit sound vibrations. Students experience vibrations using several of their senses.

Sixth graders explore the water displacement method to determine the volume of solid objects such as rocks, nails, and marbles.

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Students explore how sound waves move through liquids, solids and gases in a series of simple sound energy experiments. They describe how sound needs molecules to move and that changing the medium that it travels through changes the...

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.
