Demonstrate how to measure the volume of liquids and solids immersed in liquid to your class. They observe a teacher-led demonstration, and in small groups construct a data table that demonstrates how many marbles were used and the...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Seventh graders investigate the particulate level of solids, liquids, and gases. They examine how the particle method show the interplay between scientific theories and evidence.

Students describe properties of liquids and use descriptive language as a springboard to develop precise vocabulary for properties of liquids. They also use vocabulary as practiced with liquid-vocabulary card games. Finally, students...

Students examine containers and their capacity. They fill a one-cup measuring cup with water and pour cups of water into other containers. Through observation, students discover how many cups make a pint, and how many teaspoons make a...

Students investigate how water goes from a solid to a liquid then back again.  In this experimental lesson students conduct their own experiment and see how water changes form. 

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

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 observe and explain how a change in temperature causes a physical change in a substance.  In this physical science lesson, students use a soap making kit to observe the effects of adding heat to the bar soap as they...

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...

First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

Students explore the states of water. In this science instructional activity, students use observation, measurement, and communication skills to describe water as it changes from a solid to a liquid.

Fourth graders define the term matter. They compare properties of solids, liquids, and gases. They describe how matter changes from one state to another. They classify objects as either solid, liquid, or gas.

Students observe and discuss what happens when water turns to ice and when ice turns into water. In this freezing and melting lesson plan, students observe ice and water and complete hands on activities that change their properties.

Second graders discover that everything is made of matter. they determine the properties of liquids and that like solids, liquids can be grouped or classified according to properties or qualities. they assess that solids have a definite...

Students investigate water in its solid and liquid form. In this states of matter lesson plan, 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...

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

Fourth graders identify a physical change as one that results in a change in size, shape, or state of matter. After an initial teacher-led discussion and demonstration, groups of students get together to perform an experiment which...

Middle schoolers explore heat energy and how it is used to change the phase of matter, and discover that temperature does not increase or decrease until the phase change is complete. This extremely well-written plan is packed with great...

Students observe liquids in different containers and then explore the concept that liquids have level surfaces. They identify those who are not at the center to reinforce the concept of liquid levels with a representational puzzle and...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Blow the minds of young scientists with this collection of inquiry-based investigations. Based on a series of eight videos, these "hands-on, minds-on" science lessons engage young learners in exploring a wide range of topics...

Explore various types of measurement with fourth graders. They will practice using balance pans to measure the weight of a coin and a graduated cylinder to determine the displacement volume for a bolt. The metric system will be the focus...
