Students experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...

Adolescence and teenage years are very difficult in terms of emotions, primarily due to the amount of change going on in growing teens' lives. Guide middle schoolers through disruptive changes and transitions with a set of activities...

Sixth graders, in groups, observe the difference between physical and chemical changes and create a collage of pictures to show the difference.

Students observe phase change of matter by making ice cream in bags. In this states of matter lesson, students work in pairs to churn their own ice cream in plastic bags. They make predictions about how long it will take for the milk to...

Students compare the freezing temperature of two substances by conducting an experiment to freeze liquid ice cream. They vary the amount of salt used in the ice cubes during the freezing procedure to determine the change in the...

When life hands you lemons ... experiment on them! Green chemistry gurus compare extraction methods for essential oils through a lab activity. Lab groups use traditional distillation and liquid carbon dioxide extraction...

Students explore the physical process of melting. They observe melting ice and answer questions related to energy transfer during phase changes.

It's time to increase the heat! Young chemists demonstrate heat transfer and heat capacity in an activity-packed lab, showing the transitions between solid, liquid, and gaseous phases of materials. Individuals plot data as the...

Learn the ins and outs of the properties of water through an engaging slide show. The lesson presents different facts about water including phase change, heat of fusion, heat of vaporization, and specific heat among others. 

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...

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Students investigate molecule movement according to the kinetic molecular theory. In this kinetic molecular theory lesson plan, students observe demonstrations showing that molecules speed up with increasing temperature and slow down...

Students role play molecules in a container as the container is heated to develop a definition of heat and temperature. They also observe demonstrations of conduction, convection, radiation, and phase transfer. Using these observations...

In this chemistry olympiad problem solving activity, chemistry pupils solve eight problems on a variety of topics including periodic trends, phase changes, ionization reactions, catalysts and titrations.

Sixth graders investigate the phases of the moon. In this moon phase lesson, 6th graders discover that the moon changes in a cycle as it orbits Earth. Students label pictures of moon phases and keep a moon phase journal. Students...

Third graders participate in a demonstration of the moon's phases. In this moon phase lesson plan, 3rd graders watch as the teacher demonstrates moon phases with a bright light and a Styrofoam ball. They answer questions associated with...

Ninth graders discover the reasoning behind spraying water on fruit and seedlings in preparation for hard freezes. In this conceptual physics lesson, 9th graders conduct an experiment to measure the heat released when water goes from a...

Second graders understand that the visibility of the moon changes and that is called the moon phases. In this phases of the moon lesson, 2nd graders form a circle and create the phases. Students name the phase that matches their position...

Fourth graders study the Moon phases. The lesson includes hands-on activities as well as web-based activities. They use models of the Moon and a lamp to study each of the phases of the Moon, and test their knowlege of the Moon on a web...

Fifth graders discuss the differences between chemical and physical changes. In groups, they complete experiments and discover how a physical chnage can be reversed. To end the lesson, they review the steps of the water cycle and...

Students observe physical change of melting by observing substance in original state, melting substance, allowing substance to return to original temperature, determining if substance retained its original properties, and recording results.

Sixth graders learn that the moon orbits the Earth in a predictable cycle. Each learner engages in a two-week observation of the moon. They sketch its appearance, and take note of its position in relation to objects in their yard. Some...
