Eighth graders explore chemical reactions and their products. They define a chemical reaction and describe the characteristics of a chemical reaction. Students classify chemical reactions.

In this materials and properties instructional activity, students examine the names of 15 objects. Students identify the material each of the objects is made of their properties. An answer bank in included.

Learners explore water. In this water lesson, students explore the physical properties and states of water. They observe how water changes states and document what they see.

Students observe the state changes in water. In this matter lesson, students observe, measure, and describe water as it changes state. Students explore how water can change from a solid to a liquid then back again. They journal their...

Learners investigate the properties of heat. They explore methods of temperature control and measurement. Through experimentation and activities, students design a high tech tree house. They consider electrical, solar, and natural heat...

In this physics worksheet, students determine the density of irregular solids using water displacement method to complete 7 problems and short answer questions.

Students explore the effects that extreme temperatures have on the material properties of solids. They investigate the properties of a material whose state depends on extreme temperatures and witness how it interacts with room...

How can we find volume if it a shape isn't easy to measure? Investigate methods for determining this as the volume of regular and irregular objects is explored in several stations. Learners discover that when the standard formula for...

Second graders discover what changes occur in various types of matter under different conditions. They make predictions about the changes in an apple left out in the air, water placed in a freezer, and a nail left in a cup of water. They...
