A New Phase In Town
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...

Using the Combining Test to Identify Unknown Liquids
Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water.

Fresh Water and land of Kiribati and Hawaii (Molokai)
Fourth graders examine the islands of Hawaii. Using this information, they organize it and create a map or graph that represents the data. As a class, they discuss how the watersheds on the islands are different and how people react to...
Curated OER
Ice Cream
Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...
Curated OER
Ice Cream Blizzards
Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...
Curated OER
Creative Expressions: Phase Changes
Students place themselves in the position of a water molecule, ice molecule, or steam molecule and then describe the process of changing phase.
Curated OER
Solids and Water
Learners 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...
Curated OER
What Can We Do To Change These Materials
First graders perform experiments to investigate property changes that occur in materials or matter. In the science lab, they use heat to explore changes in rice, sand, gelatin, baking soda and more. Learners observe and record the...
Curated OER
Strength of Water
Students perform experiments using flexible bottles of water and eyedroppers partially filled and placed in the bottle. They record what happens when they tighten the bottle lid and squeeze the bottle.
Curated OER
How to Make Water Run Uphill
Students observe science demonstration. In this science lesson, students watch an experiment showing water moving up from an area of higher concentration to an area of lower concentration, due to a change in atmospheric pressure.
Curated OER
What Is In The Water?
Learners investigate the biotic and abiotic factors that are found in an aquatic ecosystem. The emphasis is upon the investigation of present an projections of future water quality. Then students visit a local body of water to gather...
Curated OER
Water Regulation
High schoolers use their basic knowledge of physiology to analyze graphical data of paramecia under diverse conditions. From the data analysis, Students develop explanations of the animal's response to the concentration of different...
Curated OER
Looking At Water: a Walking Field Trip
Fourth graders observe the effects of water on the soil and record those effect by drawing sketches of water erosion and conservation practices.
Curated OER
Global Water Cycle & Heat Flow
Students experiment to discover how different variables affect the water cycle. They do hat flow experiments and construct a computer heat flow model.
Curated OER
Dirty Water: A Case Study
Learners identify the causes of arsenic contamination. They list the world organizations involved in ensuring sanitary water supplies. Students describe various methods to mitigate arsenic contamination.
Curated OER
Physical Difference and Classification
Students use a microscope and observation skills to compare and contrast several physical properties and develop a classification system.
Space Awareness
The Big Meltdown
Explore the world (our world) of melting ice caps. Why are these caps melting? What is the effect of melting ice caps? Dive into the ever-present issue of global warming with a resource that has learners looking at data and participating...

Do Cities Affect the Weather? (Making a Cloud in a Bottle)
The dynamics of a city can have a drastic effect on the weather. A hands-on lesson asks learners to build a model to illustrate how city pollution provides a nucleus for condensation. The greater the pollution, the greater chance for...
Curated OER
Effects of Weathering
Here's a great geology lesson for 3rd graders on weathering and erosion of soil. After a class discussion on how nature can "move a mountain," learners take a look at how a modern phenoma called acid rain can also cause weathering and...

Butterfly Stroke
Swimmers improve their times by understanding the physics of their sport. As a swimmer moves through the water, the efficiency of motion affects the resulting velocity. Through an interactive simulation, pupils change the level of motion...
Curated OER
Ice Floats
Students explore the changing density of water. In this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to living things.
Curated OER
Hot and Cold Colors
Students examine how temperature effects changes in materials. In this physical science lesson, students use food coloring and cups of water of varying temperatures to observe the effects temperature has on matter. Students predict and...
Curated OER
Volume of Gas
Eighth graders investigate the effect of temperature on the volume of a gas in a closed container. They measure the height of the water in their beaker/container, conduct their experiment, and create a graph to illustrate their data.
