Molecules Matter
Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a chemistry discussion,...
Curated OER
States of Matter
In this matter activity, learners read a chart that uses water to show the three most common states of matter. Students review the properties of solids. This activity has 2 graphic organizers and 8 fill in the blank questions.

Matter: The 3 States of Water
The states of water are the focus of this PowerPoint. The presentation includes definitions of liquids, solids, and vapors. It also includes examples and illustrations of each of the states of water and information about how water can...
Curated OER
Changes of State
Students examine molecules and the changes in energy of a system. In this energy systems lesson students complete a lab activity and describe changes of state.
Curated OER
Water and Ice
Young scholars explore water as it changes states of matter. In this physical property lesson, students use observation, measurement, and communication skills to describe changes in water as it goes from a solid to a liquid and back again.
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,...

Changing State: Evaporation
Why do experiments require a control? Guide scholars through designing an experiment to see what they can do to evaporate water faster with a lesson that stresses the importance of controlling all variables. The second activity allows...
Curated OER
Exploring Phases of Matter
Students discuss and experiment with the phases of water. In this phases of matter activity, students recognize the different states of matter. Students measure and record changes and understand when the state changes.

Exploring Moisture on the Outside of a Cold Cup
As a stand-alone or as part of the intended unit, this is a valid investigation of what causes condensation to occur. By limiting the amount of air around a cold cup of water and comparing it to one out in the open, they find that the...
Curated OER
Matter
Students recognize that some changes to matter are reversible and some are not. In this matter lesson, students experiment a physical and chemical change. Students record experiment results in their science journals. Students act out...
Curated OER
Mixtures of Matter
Students experiment with mixtures of matter. In this matter instructional activity, students investigate which liquids form a solution when mixed together and which do not. Students also identify which solids can be separated from matter.

Evidence of Chemical Change
In this chemical change worksheet, students conduct 4 experiments set up around the room. They follow the instructions at each station for each experiment and list the physical properties and observe any changes at each station. Students...
Curated OER
Phase Changes
In this phase change worksheet, students read about the particles in substances that speed up and slow down for substances to change phases. They answer eight questions about phase changes, the states of matter and how changing...
Curated OER
States of Matter Mini-Unit
Students identify he phases of matter (solid, liquid, gas), and why they take place. They comprehend what a physical change is and what a chemical change is. Students know the difference between a Mixture and a Solution.
