Motion
1. The velocity of an object is the rate of change of its position.
Forces
2. Unbalanced forces cause changes in velocity.
Structure of Matter
3. Each of the more than 100 elements of matter has distinct properties and a distinct atomic structure. All forms of matter are composed of one or more of the elements.
Earth in the Solar System (Earth Sciences)
4. The structure and composition of the universe can be learned from studying stars and galaxies and their evolution.
Reactions
5. Chemical reactions are processes in which atoms are rearranged into different combinations of molecules.
Chemistry of Living Systems (Life Sciences)
6. Principles of chemistry underlie the functioning of biological systems.
Periodic Table
7. The organization of the periodic table is based on the properties of the elements and reflects the structure of atoms.
Density and Buoyancy
8. All objects experience a buoyant force when immersed in a fluid.
Investigation and Experimentation
9. Scientific progress is made by asking meaningful questions and conducting careful investigations. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations
