Continuum of Activities
The list below represents a continuum of activities: resources categorized by Standard/Eligible Content that teachers may use to move students toward proficiency. Using LEA curriculum and available materials and resources, teachers can customize the activity statements/questions for classroom use.
This continuum of activities offers:
- Instructional activities designed to be integrated into planned lessons
- Questions/activities that grow in complexity
- Opportunities for differentiation for each student’s level of performance

Activities
- Water has a positive end and a negative end, which gives it the ability to “stick” to itself. Identify this characteristic
- What molecule is in both the reactants and products of photosynthesis?
- Why does water move from the roots to the leaves of plants?
- Water molecules move up a piece of paper in the chromatography lab. What two properties of water allow this upward movement of water. Describe each property.
- A water spider is a type of insect that can walk on the surface of a pond. Explain how the properties of water allow this to occur.
- Water has a higher specific heat than the materials around it. Explain how this factors into your day at the beach.
- When wind blows over the surface of a leaf water is lost from the leaf. Explain how this then causes a chain reaction all the way down to the roots.
Answer Key/Rubric
- Polarity
- Water
- Water's cohesion causes it to "pull" towards the leaves
- Acceptable answers include, but are not limited to:
- cohesion- water “sticks” to water
- adhesion- water “sticks” to other substances like paper
- The cohesion of water forms a “skin” on the top surface and the insect can walk of it without breaking the bonds between the molecules.
- Acceptable answers include, but are not limited to:
- The sand is colder than the water at night
- The water is colder than the sand during the day.
- Acceptable answers include, but are not limited to:
- The water in the leaf is blown out of the stomates
- The stare molecules in the xylem are pulled up by cohesion and adhesion, and this pulls water out of the soil at the roots.
