Students will understand the property and structure of matter; sources and properties of energy. Students will make observations as ice cubes of various colors are melted.
Students will work collaboratively to explore absorption and reflection through the construction of a solar water heater.
Students use water to explore its properties as a solid, liquid or gas.
In this unit, students explore the concept of matter as they work through a series of 8 hands-on lessons. Students investigate mass, volume, physical change and chemical change in this comprehensive unit. An assessment is included at the end of the unit, and teacher background information is also provided.
Students will identify and explain changes in matter that occur when heat is added and taken away.
In this lesson, students explore the properties of water and hypothesize how to cause changes from a solid and gas state to a liquid state. Students use their new science knowledge to have an ice cube melt race.
This is the educator's guide for a set of activities that teach students about humans' endeavors to return to the moon. The emphasis is for students to understand that engineers must "imagine and plan" before they begin to build and experiment. Each activity features objectives, a list of materials, educator information, procedures, and student worksheets. Students should work in teams to complete the activities. Note: Activities do not align to all objectives that are listed; specific activities align to specific objectives.
Students will create an endothermic chemical reaction. Students will observe and describe the ingredients. They will measure the temperature of the milk and the ice. After making ice cream, students will measure the temperature of the ice cream (if thermometer is sanitized), and the ice/salt mixture. Students will observe and describe the changes in the physical properties of the ingredients. Students will taste the ice cream, and use their senses to describe the ice cream.
In this activity, students investigate the three forms of matter. Students create a snow figure outdoors or as frozen ice in a mold. Students will make predictions as to how long it will take the snow/ice to melt and then test it. Students will then use clay to make models of water as frozen, melting, melted, and evaporated. Students will compare the models with their actual events.

In this activity, students test the rate that different shapes of ice cubes melt.
Students will compete to create ice sculptures and use a camera phone or tablet with a time-lapse application to record and then play back at fast speed these sculptures melting.
In this activity, students use art supplies to create an original drawing showing water in its three states of matter.
Students examine the role of heat as water changes from a solid to liquid to a gas and back again.
In this lesson, students learn that heat is produced from mechanical and electrical machines and human activities.
Students explore the states of water and its physical properties.
In this lesson, students work in teams of four as they conduct four controlled Jell-O experiments over a two-day period. Styrofoam, sugar, salt, and room temperature treatments are compared to control Jell-O to investigate the effect of these treatments on the phase change of Jell-O from liquid to solid (freezing point). The Take It Further section explores the environmental pros and cons of using salt (one of the Jell-O treatments) to improve roadway safety.
