Students differentiate the different phases of matter. In this chemistry lesson, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.

A 30-question multiple choice chemistry test challenges takers. Topics touched upon include thermochemistry, equilibrium, behavior of gases, and pH. Problem solving is required in order to answer most of the questions. Other questions...

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 observe the melting of ice. In this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.

Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...

Students explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

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...

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

Students work in small groups researching the impact of climate change on a particular country, and predict future impacts for this country. They simulate an international summit on climate change. Students understand the impact of the...

Introduce middle school science learners to condensation with this presentation. It begins with a brief explanation of the process and humidity, but does not present all of the details. Three demonstrations need to be set up ahead of...

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

Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

In this phases learning exercise, students rank the chemical compounds by decreasing vapor pressure. Students use a phase diagram to determine if water undergoes any phase transitions during the four steps described. This learning...

In this science activity, students examine the physical changes associated with the change of temperature and mixtures. The answers are included.

In this physics worksheet, learners examine how phase-locked loop circuits works and answer 8 short answer questions about it. They explain how FM radio communication works.

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...

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...

Students explore why when you examine the moon depends on its location in relationship to the sun and Earth. The moon never goes away or changes shape-we just see a different fraction of sunlight being reflected from the moon to Earth.

Ignore the full moon, it's just a phase. Young scholars observe and record the moon during a full cycle before learning to predict future phases. Then the instructor leads a discussion on the other solar system objects that...

View the moon changes from space while simultaneously experiencing the changes on Earth. A creative lesson allows pupils to view the big picture as they watch the orbit of the moon through a calendar period. At the same time, they see...

Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

Students make a flip book. In this moon lesson plan, students review the moon phases and how they occur. Students make a flip book to show the moon's motion around the Earth.

Five multiple choice questions are provided in the handout about the phases of the moon. A digaram is included to help astronomy learners answer the questions. The diagram is meant to represent the appearance of the moon from the...

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...
