You can't unring a bell, but can you unmelt an ice cube? Readers consider reversible and irreversible changes with a short informational reading passage and accompanying comprehension questions.

High schoolers describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas,...

Young scholars examine the changing states of water. In this solid, liquid, gas instructional activity, students discover that water changes when heated or cooled. Young scholars make predictions and then use the...

Students explore the components of matter. They discover what matter is, the states of matter, and how heat and cold cause it to change states in an online format. In addition, they complete internet-based lessons, activities, and quizzes.

Students explore physical sciences by participating in a class experiment. In this matter lesson, students identify the three forms of matter and their physical differences. Students utilize cookie dough to create a play dough like...

Students explore liquids and solids by conducting in class experiments. In this matter instructional activity, students define the properties of matter and how heat can change those properties. Students experiment with heating objects...

Third graders sing a piggyback song to explore the parts of the water cycle and then illustrate and label the water cycle in their science journals.

Fourth graders examine matter and the periodic table of elements. In this matter lesson, 4th graders discuss atoms and their composition. Students explore the periodic table of elements and use it to spell words out of the elements.

Students discover how water expands when frozen during a glacier. In this matter lesson, students fill a glass jar with water, leaving no room for air in the jar and place it in the freezer.  Students retrieve the jar and notice the...

First graders break into groups of five students and are given 15 different objects and 3 posters. They group the objects into 3 different families with all the objects in each category placed on one of the posters. They choose whatever...

Young scientists discover how sea otters' habitats have changed due to human impact. Through conversation, video observation, and story reading, scholars identify how human interactions change a specific ecosystem in both positive and...

Eighth graders analyze physical change in mass. In this chemistry activity, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with...

Students practice spending money by completing math word sentences.  In this economics lesson, students utilize problem solving strategies to complete word problems written on the board involving making purchases with money....

Students keep a weather log. In this weather and temperature lesson, students discuss the information that can be obtained from a map and lead into a discussion about temperature. Students watch a video about temperature and...

Students review what a pattern is and they create a pattern on a fish. They are reminded that patterns do not change halfway through and they paint over it with watercolor paints. They display their fish on the walls.

Students explore volcanoes. In this science instructional activity, students discuss the characteristics of volcanoes and view a video segment about a volcano. Students examine plate tectonics.

Eighth graders practice balancing chemical equations. In this chemistry activity, 8th graders explain why it is necessary to balance equations. They complete practice worksheets individually.

High schoolers will identify the factors that contribute to erosion and weathering. They will start by differentiating between chemical and mechanical weathering. They then apply what they learned by playing the online jeopardy game. Key...

A chemistry instructional activity presents 14 chemical reactions for scholars to observe, write the equation, and balance the equations. Additionally, it provides ways to extend the activity as it relates to catalysts.

Learners find coordinate points on a grid and create a line graph with those points. This lesson should ideally be used during a unit on various types of graphs. They make and use coordinate systems to specify locations and to describe...
