Continuum of Activities

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

  1. ______________ is a factor that speeds up a chemical reaction.
    1. Enzyme
    2. Acid
    3. Base
    4. Catalyst

  2. ______________ is released or absorbed in a chemical change.
    1. Salts
    2. Energy
    3. Carbon
    4. Oxygen
  1. How are reactants different from products (in terms of location and properties)?

  2. Given a list of reactants and products, construct a T-chart to categorize each accordingly.
  1. Illustrate and label photosynthesis and cellular respiration. Remember to include the products and the reactants.

  2. Chemical reactions do not only occur in science labs. Identify two chemical reactions that happen in the everyday world and describe the reactants and products.

Answer Key/Rubric

  1. D

  2. B.

  3. In a chemical equation, the reactants are the substances that you start with and the products are the substances that are created from by the reaction.

  4. Acceptable answers may include, but are not limited to:
    1. Reactants – water, oxygen, and iron/hydrogen and 2 oxygen/carbon and 2 oxygen
    2. Products – rust/water/carbon dioxide
  1.  


















  1. Acceptable responses might include, but not be limited to:
    • Metal rusting – metal + water + oxygen → rust (Fe + O2 + H2O → Fe2O3. XH2O)
    • Photosynthesis – carbon dioxide + water + sunlight → glucose + oxygen (6 CO2+ 6 H2O + Light energy → C6H12O6 + 6 O2)
    • Aerobic Respiration – glucose + oxygen → carbon dioxide + water + energy (C6H12O6 + 6O2 → 6CO2+ 6H2O + Energy)
