3.1.3.C2. Describe animal characteristics that are necessary for survival.
3.1.3.C3. (CONSTANCY AND CHANGE) Recognize that fossils provide us with information about living things that inhabited the Earth long ago

3.2. Physical Sciences: Chemistry and Physics

3.2.A. Chemistry
3.2.3.A1a. Differentiate between properties of objects such as size, shape, and weight and properties of materials that make up the objects such as color, texture, and hardness.
3.2.3.A1b. Differentiate between the three states of matter, classifying a substance as a solid, liquid, or gas.
3.2.3.A2. Recognize that all objects and materials in the world are made of matter.
3.2.3.A3. Demonstrate how heating and cooling may cause changes in the properties of materials including phase changes.
3.2.3.A4. Use basic reactions to demonstrate observable changes in properties of matter (e.g., burning, cooking).
3.2.3.A5. (CONSTANCY AND CHANGE) Recognize that everything is made of matter.
3.2.B. Physics
3.2.3.B1. Explain how movement can be described in many ways.
3.2.3.B2a. Explore energy's ability to cause motion or create change.
3.2.3.B2b. Explore how energy can be found in moving objects, light, sound, and heat.
3.2.3.B5. Recognize that light travels in a straight line until it strikes an object or travels from one material to another

3.3. Earth and Space Sciences

3.3.A. Earth Structure, Processes and Cycles
3.3.3.A1. Explain and give examples of the ways in which soil is formed.
3.3.3.A2. Identify the physical properties of minerals and demonstrate how minerals can be tested for these different physical properties.
3.3.3.A4. Connect the various forms of precipitation to the weather in a particular place and time.
3.3.3.A5. Explain how air temperature, moisture, wind speed and direction, and precipitation make up the weather in a particular place and time.
3.3.B. Origin and Evolution of the Universe
3.3.3.B1a. Relate the rotation of the earth and day/night, to the apparent movement of the sun, moon, and stars across the sky.
3.3.3.B1b. Describe the changes that occur in the observable shape of the moon over the course of a month.

3.4. Technology and Engineering Education

3.4.A. The Scope of Technology

4.3. Natural Resources

4.3.3.A. Identify the natural resources used to make various products.
4.3.3.B. Identify local natural resources.

4.4. Agriculture and Society

4.4.3.A. Identify Pennsylvania crops that provide food for the table and fiber for textiles.
4.4.3.C. Use scientific inquiry to investigate what animals and plants need to grow.

4.5. Humans and the Environment

PA.SI. Science as Inquiry

SI.3. Understand that all scientific investigations involve asking and answering questions and comparing the answer with what is already known.

SI.5. Use simple equipment (tools and other technologies) to gather data and understand that this allows scientists to collect more information than relying only on their senses to gather information.

SI.6. Use data/evidence to construct explanations and understand that scientists develop explanations based on their evidence and compare them with their current scientific knowledge.
