Third graders simulate weathering and erosion using sand and soil. They define weathering and the ways in which surfaces become weathered. Working as a class, 3rd graders complete various activities that demonstrate physical and...

Students identify the effect of light on objects. In this scientific inquiry lesson, students use a chart to write a hypothesis about what will happen when colored construction paper is left in sunlight. Students observe and discuss the...

Students measure in metric units and use a stopwatch, calculator. They collect data with minimal instructions after the initial pre-activity briefing, then record data in the data sheets provided.

Fifth graders use common household items to build landforms and simulate weathering and erosion.

Fourth graders identify the characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and separate or sort items using these properties. Students explain...

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Students review how physical and chemical change while discussing the properties. They diagram the electron dot for the first four elements in the periodic table. Students identify elements and state what they know while investigating...

Fourth graders study physical and chemical weathering. They explain how the processes of weathering and erosion change and move materials that become soil. They create a K-W-L chart to show what they know and list what else they would...

Students experiment with silly putty.  For this chemical changes lesson students work in groups, perform tests and collect data.

Students explore elasticity and describe the effects of temperature changes on physical properties.  In this rubber band stretch activity students complete an experimental activity and show their results. 

Students complete a unit on the chemical and technological processes of food preparation. They observe various experiments, describe changes in materials through cooking, identify safety and hygiene issues, and cook various recipes.

Fourth graders accurately describe various states of matter, Through experimentation, they change a variable to create a new state of matter. Students record their observations about the way matter is changed and the changes that occur...

Young scholars describe characteristics and common uses of acids and bases. They describe the role of natural indicators in the chemistry of acids and bases after testing and making observations on a variety of plant extracts. Students...

Eighth graders conduct an experiment that analyzes the physical and chemical characteristics of various water samples. They discuss the procedures and safety concerns for the water test, and test their water samples to determine if they...

Students study the aspects of a forest floor ecosystem, including decomposition, the water cycle, food webs, the needs of living things, and physical vs. chemical change over an extended period. In addition, students conduct observations...

In this soil formation worksheet, students will review examples of chemical weathering and biological weathering. Students will also review the different soil layers and how they are created. This worksheet has 6 matching, 5 multiple...

Students examine the effects of heating on various crystals. They formulate and revise scientific explanations and models using logic and evidence. Students work individually during this experiment.

In this matter worksheet, students are given 10 sentences with italicized terms that are wrong. Students correct the terms to appropriately fit the sentences. Topics are related to matter such as physical and chemical properties, solids,...

Students work as a team to gather organisms from a stream to evaluate if the water quality is excellent, good, or fair to poor.

Students study the flow of water in the environment.  In this water cycle lesson students evaluate the consequences of changes in the water cycle using data. 

Sixth graders experiment with mixtures. In this chemistry lesson, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

Students determine the most appropriate site for a car wash, based on each site's soil characteristics (chemical, physical) and topographic features. They perform an experiment to determine the changes to three different soil types when...

Third graders explore animal characteristics by participating in a bat environment game. In this natural habitat lesson, 3rd graders identify the physical anatomy of a bat and discuss their eating and sleeping habits. Students conduct a...

Fifth graders brainstorm a list of ways the Earth's surface can change. As a class, they are introduced to the concepts of erosion and weathering and discover how wind and water cause changes to the surface of the Earth. To end the...
