Activit #2 Matter: Is It Conserved?
Students support the law of conservation of matter with evidence. They discuss the changes observed from the burning of the candle, and the differences in mass which are observed when the same reaction is carried out in an open or...
Curated OER
Law of Conservation of Mass
Learners work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...

Urban Ecosystems 5: In Defense Of Cities
Students explain that while cities have unattractive features, the density of human life enables energy efficiency, mass transit, recycling, and other benefits which are difficult or impossible in rural areas. This is the fifth in an...
Curated OER
Describing Chemical Reactions
In this chemical reactions worksheet, students fill in 12 blanks with the appropriate terms related to chemical reactions. They also indicate if 4 statements are true or false and match 7 words with their descriptions. Students complete...
Curated OER
Einstein's BIg Idea
High schoolers discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.

Determining Momentum and Energy Loss of Balls Colliding Against Different Surfaces
Learners experiment with the bounce of balls on various surfaces. In this physics lesson, students use various surfaces to bounce balls to study the momentum. This hands-on activity with the concepts of elasticity of surfaces which is...
Curated OER
Trophic Relationships, Cycling of Chemicals, Human Impact on Ecosystems and Conservation
Pupils explore how the energy flow through a system is related to trophic levels. They investigate how organisms affect the cycling of elements and water through the biosphere. Students participate in lab activities to observe ways...
Curated OER
Energy Conservation
Class is divided into groups of 2-4 students. They then are given a list of 36 items that are found in our homes and which use electricity. They are going to pretend that because of an energy shortage, they have to pick only twelve items...
Curated OER
Melting and Freezing of Water
Students examine the three states of matter. They identify the segments of heating and cooling curves. Students analyze data and create a graph to determine the freezing and melting temperature of water.

Freezing Point Depression: Why Don’t Oceans Freeze?
Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...
Curated OER
Water and Ice
Students observe what happens to water as it goes from a solid to a liquid. In this exploratory instructional activity students gain an understanding for the water cycle while working in groups observing what happens to water as it...
Curated OER
Matter and Energy
In this matter and energy worksheet, students identify substances as solids, liquids or gases, they use the kinetic theory to describe the motion of particles and they explain the conservation of mass and energy when a substance changes...
Exploratorium
Momentum Machine
If you have a rotating office chair in your classroom, you can have physics pupils participate in this simple, yet effective demonstration of angular momentum. One partner sits in the chair, arms outstretched, holding heavy weights. The...
Curated OER
Everything about Equations
In this chemical reactions activity, students are given fifteen unbalanced equations and they must identify the reaction types, the phases of the products, the signs that a chemical change occurred and the sum of the coefficients of the...

Mass of Water vs. Ice
Young scholars examine how ice changes state and when its volume changes. In this mass lesson students complete a lab that shows them how waters volume can change.
Normal Community High School
Chemical Equations
Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

Specific Heat of Metal
Students experiment with different types of metal by dipping them in boiling water and cool water and recording temperature changes in the water. By doing this, they find the specific heat of the metals.
Curated OER
Melting and Freezing of Water
Students differentiate the three states of matter. In this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.
