Students calculate the density of regular and irregular solids and liquids. They relate the term dense to science as well as its literal meaning that society uses it as everyday. A worksheet is completed on density.

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...

Students explore permafrost.  In this 3 states of matter lesson, students identify characteristics of solids and liquids.  Students observe water and soil melting and freezing at various temperatures.  Students make...

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 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.

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 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.

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 observe, measure, and communicate while observing water convert from a solid to a liquid and back again. In this solid and liquid lesson plan, students answer questions as they observe this change.

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. 

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...

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 conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Students turn solid water (ice) into liquid water. In this solid and liquid water lesson plan, students use water, ice, cups, and heat in order to change water from one state to another. They draw their findings as well.

Students investigate mixtures made of water and familiar solid materials. They observe and discuss the changes that occur immediately and set the mixtures aside for a day. Finally, students observe the mixtures, note changes, and graph...

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 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...

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...

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.

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...

Students explore the states of water. In this water states lesson plan, students observe ice over time and the changes that take place. Students read a related text and draw their observations in a journal entry. Students discuss the...

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...

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