Third Grade Science Objectives
Embryology – The student will be able to:
- explain the life cycle of a chicken.
- observe and understand embryo development.
- investigate other animals that lay eggs and their life.
Energy – The student will be able to:
- recognize that light travels in a straight line and can be reflected by an object (mirror).
- recognize that light can travel through certain materials and not others (transparent, translucent, opaque).
- identify ways to generate heat (friction, burning, incandescent light bulb).
- demonstrate that heat can flow from one object to another by conduction.
- identify materials that act as thermal conductors or insulators.
- recognize how sound is produced when objects vibrate.
- recognize sound can be changed by changing the rate of the vibration.
Dinosaurs and Fossils – The student will be able to:
- understand the processes that created some fossils.
- understand how scientists use fossil evidence to make inferences about an organism’s characteristics.
- exam fossil evidence to determine adaptations of ancient organisms.
- infer how dinosaurs lived by examining their characteristics.
Simple Machines – The students will be able to:
- understand the concepts of force and friction.
- describe changes in motion due to outside forces (push, pull, gravity).
- explain how levers make work easier.
- explain how wheels and axles decrease force, increase distance, and decrease friction.
- explain how inclined planes make work easier.
- explain how gear systems make work easier.
- design and build a simple machine that solves a problem.
