Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

Some of kids' favorite toys are the products of science experiments. Scholars follow precise measurements to mix and create their own slime and Play-Doh. They observe the changing textures and the chemical reactions throughout the...

Pour a solid foundation of engineering into the minds of future engineers. Scholars take part in three activities to learn about civil engineering. They build a model of a cable-stayed bridge, conduct an experiment to see the effects of...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

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.  For this physical science lesson, students use a soap making kit to observe the effects of adding heat to the bar soap as they...

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....

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 energy changes from a liquid to a solid. They model the arrangement of a solid and the change in states due to changes in energy using desks and chairs. Assessment questions are provided in lesson plan.

Students explore the states of water. In this water states lesson, 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, students conduct a scientific investigation that requires them to make ooze and record their observations pertaining to it.

First graders explore Oobleck. They manipulate and observe the properties of Oobleck. Students discuss the differences between solids and liquids. They investigate Oobleck. Students write a sentence describing what they observed about...

Bright blue slides with yellow and white font make this presentation easy for learnerrs to read. The content is a brief overview of the commonly observed physical properties of matter, focusing on the differences among solids, liquids,...

Learn about radiation, convection, and conduction with a multiple choice worksheet. Each question prompts kids to decide what is different about each form of heat energy transfer, and what is the same.

Measuring volume can be a mystery for 5th graders, but this hands-on activity gives the gift of discovery. The volume of simple rectangular solids and irregular shapes are calculated through various methods including displacing liquid in...

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...

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 use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...

We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity.
