Life Science

1. Explain that animals, including people, need air, water, food, living space and shelter, and plants need air, water, nutrients (e.g., minerals), living space and light to survive. - Animal Needs to Survive
2. Identify that there are many distinct environments that support different kinds of organisms.- Ecosystems
3. Explain why organisms can survive only in environments that meet their needs (e.g., organisms that once lived on Earth have disappeared for different reasons such as natural forces or human-caused effects).  - Survival and Extinction of Organisms
4. Compare similarities and differences among individuals of the same kind of plants and animals, including people. - Plant/ Animal Similarities and Differences
5. . Explain that food is a basic need of plants and animals (e.g., plants need sunlight to make food and to grow, animals eat plants and/or other animals for food, food chain) and is important because it is a source of energy (e.g., energy used to play, ride bicycles, read, etc.).- Food Chain, Plants
6. Investigate the different structures of plants and animals that help them live in different environments (e.g., lungs, gills, leaves and roots).- Plant and Animal Structures
7. Compare the habitats of many different kinds of Ohio plants and animals and some of the ways animals depend on plants and each other.See   Ohio Plants and Ohio Animals
8. Compare the activities of Ohio's common animals (e.g., squirrels, chipmunks, deer, butterflies, bees, ants, bats and frogs) during the different seasons by describing changes in their behaviors and body covering - Ohio's Animal
9. Compare Ohio plants during the different seasons by describing changes in their appearance - Ohio Plants

Physical Science

1. Explore how things make sound (e.g., rubber bands, tuning fork, strings).       Sound
2. Explore and describe sounds (e.g., high, low, soft, loud) produced by vibrating objects.  Sound
3. Explore and describe sounds (e.g., high, low, soft, loud) produced by vibrating objects.  Light

Science and Technology

1. Explain that developing and using technology involves benefits and risks.Technology Benefits and Risks
2. Investigate why people make new products or invent new ways to meet their individual wants and needs  Inventions
3. Predict how building or trying something new might affect other people and the environment. New Productsd and their affects
4. Communicate orally, pictorially, or in written form the design process used to make something. 

Science Inquiry

1. Ask "how can I/we" questions.
2. Ask "how do you know" questions (not "why" questions) in appropriate situations and attempt to give reasonable answers when others ask questions.
3. Explore and pursue student-generated "how" questions.
4. Use appropriate safety procedures when completing scientific investigations. Safety Procedures
5. Use evidence to develop explanations of scientific investigations. (What do you think? How do you know?)
6. Recognize that explanations are generated in response to observations, events and phenomena.
7. Use appropriate tools and simple equipment/instruments to safely gather scientific data (e.g., magnifiers, non-breakable thermometers, timers, rulers, balances, calculators and other appropriate tools).       Science Tools
8. Measure properties of objects using tools such as rulers, balances and thermometers.   Science Tools
9. Use whole numbers to order, count, identify, measure and describe things and experiences. Numbers
10. Share explanations with others to provide opportunities to ask questions, examine evidence and suggest alternative explanations.

Science Ways of Knowing

1. Describe that scientific investigations generally work the same way under the same conditions. Scientific Method
2. Explain why scientists review and ask questions about the results of other scientists' work. Scientists
3. Describe ways in which using the solution to a problem might affect other people and the environment.
4. Demonstrate that in science it is helpful to work with a team and share findings with others. Scientific Teamwork
