Phase Changes of Water
A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

Introducing Measurements in the Laboratory
We use basic units of measurement to break down things and communicate clearly. The first lesson in an 11-part series teaches the proper way to measure various items. It starts simply with measuring the dimensions and areas of geometric...
Curated OER
Freezing Point Depression
Students create ice cream in a zipped bag and measure the temperature of a salt/ice mixture. They discover how salt lowers the temperature necessary to freeze ice to a solid (below 0'C).

Melting, Freezing, and More!: Phase Transitions
Third graders listen to a talk on phase transitions and view three demonstrations. In this phases of matter lesson, 3rd graders complete a worksheet as they listen about phase transitions. They move through three demonstrations of phase...

Let It Snow! Let It Melt!
Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based lesson includes a range of learning experiences, from experimenting with the rate at which ice melts...
Curated OER
The Frigid Gourmet
Students make a " science surprise" or ice cream in the lab. In this melting point depression lesson plan, students use various substances with ice to determine the effects on the melting point of ice and the ability to make ice cream....
Curated OER
Melting Ice
Students observe the melting of ice and explore the basic physical changes that occur. They gain information of how different substances change the rate of melting. Students discuss the properties of water and ice, the definition of...

Molar Mass Determination from Freezing Point Depression
Let the data tell the story. A lab activity has pupils collect temperature data on solutes as they melt and freeze. They use their data to create a cooling curve and then calculate the molar mass using the freezing point depression.

Ice Cream: a Taste of Science!!
Students define the term solution. They explain conservation of energy and energy transfer as it relate to how the milk solution became ice cream. Students are able to explain freezing point depression.

Changes Caused by Heating and Cooling
It's heating up—and cooling down—in here! A hands-on lesson allows learners to experiment with melting and freezing butter to observe changes as a substance transitions between liquid and solid form. They also view an animation that...

Water 3: Melting and Freezing
Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...
Curated OER
Heating and Cooling Curves
Learners experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...
Curated OER
Water and Ice
Pupils explore water and how it changes forms. In this investigative lesson students participate in an activity that shows them how water changes form and what it looks and feels like.
Curated OER
Ice
Students examine the different propereties of ice, such as freezing temperature. In this scientific lesson students complete several activities using ice, like making ice cream.

Water—Changing States (Part 1)
Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...
Curated OER
Ice Energy
Students explore how chemicals change water. In this chemical change lesson, students participate in an experiment to observe how salt effects ice and how ice cream freezes.
Curated OER
Water: Liquid or Solid?
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...
Curated OER
State Change
Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups,...
