DoDEA second-grade science standards

Alignments coming soon

IXL's second-grade skills will be aligned to the DoDEA Content Standards soon! Until then, you can view a complete list of second-grade standards below. Be sure to check out the unlimited science practice questions in IXL's 56 second-grade skills.


Scientific Inquiry

  • 2Sa The student will demonstrate an understanding of scientific inquiry, including the processes, skills, and mathematical thinking necessary to conduct a simple scientific investigation.

    • 2Sa.1 Carry out simple scientific investigations to answer questions about familiar objects and events.

    • 2Sa.2 Use tools (including thermometers, rain gauges, balances, and measuring cups) safely, accurately, and appropriately when gathering specific data in US customary (English) and metric units of measurement.

    • 2Sa.3 Represent and communicate simple data and explanations through drawings, tables, pictographs, bar graphs, and oral and written language.

    • 2Sa.4 Infer explanations regarding scientific observations and experiences.

    • 2Sa.5 Use appropriate safety procedures when conducting investigations.


  • 2Sb The student will demonstrate an understanding of the needs and characteristics of animals as they interact in their own distinct environments.

    • 2Sb.1 Recall the basic needs of animals (including air, water, food, and shelter) for energy, growth, and protection.

    • 2Sb.2 Classify animals (including mammals, birds, amphibians, reptiles, fish, and insects) according to their physical characteristics.

    • 2Sb.3 Explain how distinct environments throughout the world support the life of different types of animals.

    • 2Sb.4 Summarize the interdependence between animals and plants as sources of food and shelter.

    • 2Sb.5 Illustrate the various life cycles of animals (including birth and the stages of development).


  • 2Sc The student will demonstrate an understanding of daily and seasonal weather conditions.

    • 2Sc.1 Explain the effects of moving air as it interacts with objects.

    • 2Sc.2 Recall weather terminology (including temperature, wind direction, wind speed, and precipitation as rain, snow, sleet, and hail).

    • 2Sc.3 Illustrate the weather conditions of different seasons.

    • 2Sc.4 Carry out procedures to measure and record daily weather conditions (including temperature, precipitation amounts, wind speed as measured on the Beaufort scale, and wind direction as measured with a windsock or wind vane).

    • 2Sc.5 Use pictorial weather symbols to record observable sky conditions.

    • 2Sc.6 Identify safety precautions that one should take during severe weather conditions.

Properties and Changes in Matter

  • 2Sd The student will demonstrate an understanding of the properties of matter and the changes that matter undergoes.

    • 2Sd.1 Recall the properties of solids and liquids.

    • 2Sd.2 Exemplify matter that changes from a solid to a liquid and from a liquid to a solid.

    • 2Sd.3 Explain how matter can be changed in ways such as heating or cooling, cutting or tearing, bending or stretching.

    • 2Sd.4 Recognize that different materials can be mixed together and then separated again.


  • 2Se The student will demonstrate an understanding of force and motion by applying the properties of magnetism.

    • 2Se.1 Use magnets to make an object move without being touched.

    • 2Se.2 Explain how the poles of magnets affect each other (that is, they attract and repel one another).

    • 2Se.3 Identify everyday uses of magnets.
