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...

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....

In this energy and matter worksheet, students define 28 terms related to moles, matter, energy, the Law of Conservation of Energy, mass, properties of matter and states of matter.

Students investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Students examine states of matter. In this solids and liquids lesson, students conduct a scientific investigation that requires them to make ooze and record their observations pertaining to it.

Students investigate what happens to solids and liquids when they change from one form to another. In this states of matter lesson, students work in groups on a virtual experiment that requires them to collect data regarding the melting...

Young scholars investigate gases and liquids. In this states of matter online lesson, students examine how evaporation plays a part in the transition of liquids into gases as they watch a kettle of water boil and then work in small...

Young scholars complete activities to study the properties of solids and liquids. In this states of matter instructional activity, students investigate the melting and freezing of a range of materials in a virtual experiment. Young...

Students investigate water in its solid and liquid form. In this states of matter lesson, students experiment to see what happens as water goes from a solid, ice, to a liquid, water, and back again. They write about and illustrate the...

Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

Pupils explore water as it changes states of matter. In this physical property lesson, students use observation, measurement, and communication skills to describe changes in water as it goes from a solid to a liquid and back again.

Students examine states of matter. In this solids and liquids lesson, students conduct a scientific investigation that requires them to make oobleck and record their observations pertaining to it.

First graders break into groups of five students and are given 15 different objects and 3 posters. They group the objects into 3 different families with all the objects in each category placed on one of the posters. They choose whatever...

Participate in three activities that look at the earth's limited water supply and the changes water goes through as it enters each phase of the water cycle. The resource is complete with three activities that demonstrate the changing...

You can't unring a bell, but can you unmelt an ice cube? Readers consider reversible and irreversible changes with a short informational reading passage and accompanying comprehension questions.

Why do different substances have different boiling points? Through an interactive lesson, learners explore how intermolecular attractions affect boiling points. They interact with molecules through an animation and make conclusions about...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Students examine the states of matter; solids, liquids and gases. They explain how the states of matter change from one to another.

Fourth graders study evaporation and condensation as parts of the water cycle. First they determine the similarities and differences between a cup of water and an ice cube before measuring the volume of ice before melting it, and...

Middle schoolers view a video which introduces them to density and the states of matter. They experiment, collect data, and graph the boiling/freezing points of several edible items...and then make brownies!

Fourth graders explore objects that do not fit into the categories given by three states of matter. They explore why an object doesn't fit perfectly into one of the three categories. Students observe the properties of Oobleck. They...

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...

An executive is not just a leader of a company; you can also use the term to describe the president of the United States. The ninth part of a 20-part unit teaches high schoolers about the importance of the executive branch and the...

While working in small groups, students use a digital camera to take pictures of various states of matter around the school grounds. Then they download the images onto the computer. The students then have to type or list the three states...
