Curated OER
Set the Stage
Students observe evaporation in a controlled environment. Evaporation is the change of liquid water into water vapor (a gas). The rate of evaporation is determined by many factors such as air temperature and humidity, liquid temperature...
Curated OER
Water & Ice
Learners investigate the properties of water. In this states of water lesson, students explore how water goes from liquid to solid and back to liquid again. Learners use measurement, observation, and communication to describe the change.
Curated OER
Making Layered Hail Stones
Students explore how hail forms in the atmosphere, why hailstones are layered, and what accretion is. They also learn what supercooled liquids are.
Curated OER
Density Lab
Pupils use an Excel spreadsheet to calculate the density various liquids. They take pictures of their results.
Curated OER
HIV/AIDS & Other STDs, Day 3: HIV/AIDS
Students examine the characteristics of HIV and AIDS. They identify the liquids in which the disease is found and how it can be transmitted. They examine healthy behaviors to keep them from getting the disease.

How Can We Accurately Make Different Solutions of Different Concentrations?
High schoolers work together to create different solutions made from different concentrations of liquids. They record and analyze their data. They answer discussion questions to complete the lesson.
Curated OER
Quick Freeze (Demonstration)
High schoolers witness an demonstration in which a bottle of club soda will go from a liquid to a solid when it is opened and the carbon dioxide is allowed to escape. This will help them understand that the freezing point of a solution...
Curated OER
Floating
First graders discuss with the teacher if everything will float in water. They observe a marble and determine whether it will float making predictions as a class. After observing the results, they discover that liquids exert an upward...
Curated OER
Ice Cream
High schoolers explore the concept of the colligative property. Through experimentation, students lower the freezing point of a liquid in order to create a solid by using household ingredients to create ice cream.

Do Some Research: Chemistry 10
In this chemistry research activity, students read the sentence and then use a library or the Internet to find the answer and write it on the blue line. Students then write a short report about this topic: a substance, liquid, or gas,...
Curated OER
Water and Ice
Students study the water cycle and states of matter. In this water cycle instructional activity, students observe ice for a period of time and record their observations. Students create a Venn Diagram comparing water in solid form and...
Curated OER
Water and Ice
Students explore what happens to water as it goes from solid to liquid and back. In this state of matter lesson, students observe, measure, and describe water as it changes state.
Curated OER
Flower Food
In this flower worksheet, students create home made flower preservatives. Ingredients include water, sugar, lemon juice, vinegar, or liquid bleach.
Curated OER
The Ideal Gas Equation
In this chemistry worksheet, students use the Ideal Gas Equation site by clicking on the New Question button and responding to the question that is presented in the box. From there they determine the value of their answer and enter it...
Curated OER
Water and Ice
Students will work in small groups, observing an ice cube and recording a description, the feel of the ice, and how it looks when put in another container. Students observe changes in the ice over 15 minute intervals, then freeze the...

The Crusty Earth
Geology rocks — literally! A geology chapter offers eleven activities at four different levels. Scholars enjoy completing hands-on experiments before applying critical thinking skills following a share, process, generalize, apply,...
American Chemical Society
Changing State: Melting
Dry ice is extremely cold — it is -109.3°F or -78.5°C. Scholars observe and explain the molecular motion associated with melting. Then they design their own experiments to speed up the melting process. Finally, a teacher presents a...
Science 4 Inquiry
A Whole New World: The Search for Water
Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Insoluble Paintings
Insolubility and density? Yup, it's art class, of course. To create insoluble paintings that continually move and change, kids mix water-based paint with mineral oil and seal the mixture in laminating pouches.
Cornell University
Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...
