When your upper elementary or middle school class is learning about chemical changes, these activities help demonstrate the concepts. In Part A, they submerge and place a nail partially underwater, then after a week they make...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

Students identify the signs that a chemical reaction took place. In this chemistry lesson, students role play the movement of different molecules of matter. They classify matter according to their properties.

Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Students define the words "reversible" and "irreversible." They complete a worksheet that shows a number of changes. Students must decide which are reversible and which are irreversible.

Fifth graders evaluate evidence that indicates a physical change has occurred. In this colonial living lesson, 5th graders explore the science involved in the making of items used in colonial life, such as, bread, butter, soap, candles,...

Fourth graders observe what is happening when an Alka-Seltzer tablet is placed in a clear cup of water. They observe the release of carbon dioxide gas. Pupils answer the question of how much as is released by observing the experiment...

Students see evidence of chemical reaction and follow the scientific method to hypothesize, observe, and reach conclusions. They conduct a series of egg based experiments such as forming crystals and complete journal activities as a...

Students explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...

Students describe the history of materials. They use the kinetic (particle) theory to explain changes of state in matter and trace the flow of heat during changes of state and chemical changes.

Third graders explore forms of matter through reading, hands-on science activities, and research using the Internet. Students create a booklet, directions given, that they title and decorate, to later serve as a review visualization...

Middle schoolers show the relationship between the need for plants to undergo photosynthesis in order to generate oxygen. They see the flaws associated with this thinking because of the lack of CO2 and H2O and lack of sufficient gravity...

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Young scholars use satellite data to explore sea surface temperature. They explore the relationship between the rotation of the Earth, the path of ocean current and air pressure centers. After studying maps of sea surface temperature and...

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

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 complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

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

Students identify patterns and relationships from data that is collected and solve variables.  In this investigative lesson plan students study ocean productivity, the nitrogen cycle and phytoplankton then answer questions.

High schoolers work with a partner to determine the identity of an unknown element based on given descriptions. Groups use classroom textbooks, encyclopedias, and science internet sites to identify their unknown element then write a...

Students consider the adaptation of life forms through natural selection to fill various niches and accommodate changing environmental conditions. They select an ecosystem and conduct research to provide as much detailed information as...

Students identify he phases of matter (solid, liquid, gas), and why they take place. They comprehend what a physical change is and what a chemical change is. Students know the difference between a Mixture and a Solution.

Learners investigate the physical, chemical and biological parameters necessary to establish an ecological baseline. Establishing an ecological baseline not only shows the ecological characteristics of a creek but makes the possible...
