Fifth graders develop a deeper understanding of chemical and physical changes. They explain how salt is made, used, and the affects it has on the body. They explain that salt in moderation is important to our health.

Students review properties of matter and discuss how materials change when things are done to them. They observe how materials change as a reaction to temperature by following the procedure to make ice cream and recording the temperature...

In this chapters 2 and 3 science guided reading worksheet, students read corresponding material pertaining chemical reactions and the periodic chart answering 40 fill in the blank questions.

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,...

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...

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...

Fifth graders perform experiments with color mixing and color changing. They observe the differences between physical and chemical changes and record their observations in journals.

In this matter worksheet, students complete a graphic organizer by describing the properties of matter, the changes of matter, and how matter can form mixtures.

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

Students study the chemical and physical weathering of "rocks".  In this weathering experiments lesson students complete a lab that demonstrates how rocks weather.

In this chemical reaction worksheet, students experiment with soda and Mentos candy to observe a chemical reaction. Students describe the reaction, identify the investigation as descriptive or qualitative and make a prediction if the...

Students investigate friction between different surfaces. In this physics lesson, students research biomaterials that can reduce friction. They calculate efficiency using a mathematical formula.

Young scholars collect snow samples around their school. They explore the concepts of density and phase change as well as the math skills of measurement and statistics. Students explore the water cycle through an interactive, down...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Mystery is an exciting genre for young readers to investigate. The plots are so intriguing! Here is a series of lessons featuring Sherlock Holmes stories that invite learners to enter the world of the mystery genre.  Based on what...

Why don't we just capture carbon dioxide in the air and store it somewhere else? A hands-on lesson allows scholars to explore a complex concept. First, they will create a carbonated beverage, and then they will determine...

Solidify understanding of the properties of crystals by crushing them to compare hardness. After some class discussion, a procedure is planned, and then small groups go about making observations as they crush five different crystal...

In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.

Each group talks about how to test unknown liquids based on their findings in the previous experiment. In this second of four activities, they test unknowns on wax paper, newspaper, and construction paper. As a stand-alone, this lesson...

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...

Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...
