Students describe how molecules of the different phases of matter move according to the Kinetic Theory. In this chemistry lesson, students observe and participate in teacher demos. They give real world applications of the kinetic theory.

In this phase change activity, students read about the particles in substances that speed up and slow down for substances to change phases. They answer eight questions about phase changes, the states of matter and how changing...

Fifth graders explore the phases of matter, make observations of matter, the physical and chemical properties of matter, solutions and mixtures, formation of molecules and atoms and molecules all through hands on activities.

Students will observe, measure and describe the phase changes of ice. In this science lesson plan, students observe ice as it changes phases. Qualaitative notations made by individual students will be shared and compared.

Students define the term solution. They explain conservation of energy and energy transfer as it relate to how the milk solution became ice cream. Students are able to explain freezing point depression.

Every topic under the sun is covered in this New York State Regents High School Examination. With the focus of earth science, participants answer 85 quesitons about the solar system, geologic time, rocks and minerals, landforms, and...

In this chemistry worksheet, students identify the three main phases of matter. Then they search for information about each element on a Chem Time Clock. Students use the chemical symbol to identify each element.

Students explore coming of age ceremonies. In this rites of passage lesson, students research spiritual, religious, and secular child and adolescent rites of passage rituals. Students design personal rites of passage.

Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

Seventh graders divide into small groups to construct several models. Each group builds with an accompanying chart showing the colors of gumdrops used for the protons, electrons, and neutrons.)

Eighth graders create a slide show to show their knowledge of the eight lunar phases and lunar rotation and revolutionary periods.

Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...

Entropy, it isn't what it used to be. Presentation includes kinetic-molecular theory, heat and internal energy, thermal equilibrium, temperature scales, laws of thermodynamics, entropy, latent heat of fusion, specific heat, calorimetry,...

Students use a simple physical model of the Earth, sun, and moon to understand why the moon changes phases from the perspective of Earthly observers. They hold up balls representing the moon in a room with a single light source to see...

In this heating and cooling curve instructional activity, students use a given graph of a substance being heated from a solid to a liquid and then a gas over time. They use the graph to answer eleven questions about the phases of the...

In this chemistry practice activity, students select the correct response to the given questions. Students apply knowledge about the states of matter, finding vapor pressure and atmospheric pressure.

How does water pollution affect the environment? Provide your class with the resources to answer this question as they learn about eutrophication and ecosystem changes. Over two weeks, they simulate the effects of pollution on the...

Students explore permafrost.  In this 3 states of matter instructional activity, students identify characteristics of solids and liquids.  Students observe water and soil melting and freezing at various temperatures. ...

Students differentiate the three states of matter. For this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.

Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...

Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups,...

Learners explore the six phase transitions between gases, liquids and solids for a variety of elements. Each group of students focuses on a different element, investigating its physical properties during each of the six phase transitions.
