Second graders identify three forms of matter- solids, liquids, and gases with 100% accuracy. They observe water evaporating from an open container and water evaporating and condensing in a closed container. The students assess that a...

In this matter and chemical changes worksheet, students write symbols and formulas for 2 chemical reactions. They write words for 1 chemical reaction given in symbols and formulas. They draw a diagram representing a chemical reaction and...

Students, through the use of examining video clips and Websites, become familiar with the reasons that the settlers wanted the land, broke treaties, and initiated the Indian Removal Act leading to the Trail of Tears.

Examine the changing nature of language in the U.S. View and discuss excerpts from a PBS documentary with your class and then conduct Internet research, and complete a team project on the evolution of teen expressions. 

Students make ice cream. They use the experimental process to improve the ice cream working with variables in the recipes.

Students investigate the properties of water. In this states of water lesson, students explore how water goes from liquid to solid and back to liquid again. Students use measurement, observation, and communication to describe the change.

Students discover the forms water can take. In this hands-on science lesson, students examine how water can change from a solid to a liquid and then back again.

What can one learn about a planet based on a small surface sample? Learners will explore artifacts from a mystery planet and see what they can determine about the planet based on the evidence in front of them. 

The earth is a delicate and fragile thing; Why not engage your class in a craft project that will make them aware of our environment? Earth Day is celebrated as recycled materials are used to create earth window hangings. Crayons are...

More people, more garbage! Young environmentalists graph population growth against the amount of garbage generated per year and find a linear model that best fits the data. This is an older resource that could benefit from more recent...

Fifth graders discover that Anza and Washington lived at the same time but on opposite sides of the American Continent. They identify differences and similarities in their lives. They present the data in an illustrated time line

Fifth graders examine the differences between chemical and physical changes. As a class, they are read a scenerio and determine whether it was deliberate act or not. In groups, they observe the changes of an alka-seltzer tablet and...

Second graders experiment with heating and cooling and research the states of matter (solid, liquid, gas).

High schoolers 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.

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...

The presentation covers Fahrenheit, Celsius, and Kelvin scales for temperature as well as conduction, convection, and radiation.

In this matter worksheet, learners answer ten questions about matter including the phase of matter, mixtures and how they are different from compounds, the physical and chemical properties of matter and the difference between homogeneous...

Young scholars use fossil leaves and a mathematical formula to study climate change. In this climate change and fossil lesson plan, students determine the differences in temperatures during two different times during the Cenozoic era...

Students, after viewing a video and researching the changes in society during the Victorian period, assess a prediction-confirmation guide to consider how changes in burial customs in the late 1800's reflect the changes in society as a...

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

The solar energy industry in the United States added more jobs in 2015 than the oil and gas extraction and pipeline industries combined. With the field growing so rapidly, it's essential to understand what solar energy is and how it...

Students examine how candles work and how scientific theories are developed and tested. Students propose hypotheses about what is burning in a candle then perform tests in order to develop their scientific theory. After a teacher...

In this matter and change worksheet, students answer 24 questions on topics such as elements, compounds, mixtures and chemical reactions. Students answer questions about the properties of matter such as their physical state and shape. In...

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...
