Science Grade 8


By the end of eighth grade, students who are making adequate progress in science are able to:

8.1 Use the scientific method to problem solve.

8.2 Make basic measurements (length, mass, volume, etc.) using the SI or metric system.

8.3 Describe the basic structure of an atom (Bohr model) and the characteristics of the fundamental (proton, neutron, electron) subatomic particles.

8.4 Understand that matter is made up of particles whose properties determine the observable characteristics of matter and its reactivity.

8.5 Classify matter based on its physical and chemical properties.

8.6  Understand how the periodic table is organized. Additionally, know how to use it to find information (atomic number, atomic mass, electron configuration, etc.) about the elements.

8.7 Write formulas for, as well as name, inorganic compounds.

8.8 Demonstrate the Law of Conservation of Mass by balancing chemical equations.

8.9 Complete data tables and charts, then answer questions based on analysis of the data.

8.10  Make and distinguish among observations (qualitative/quantitative), conclusions (inferences) and predictions.

8.11   Begin to recognize and develop controls needed in experiments.

8.12  Basic understanding of acids, bases, and salts. Additionally, be able to describe the pH scale and neutralization.

8.13  Identify the basic components of solutions (solute and solvent) as well as identify factors that affect rate of solution. 

8.14   Analyze data presented in a solubility graph.

8.15   Discuss the basic concepts associated with force, mass, speed,  acceleration, friction, and gravity.

8.16   Understand the basic concepts involved with Newton’s laws of motion.

8.17   Identify energy changes in various systems. 

8.18 Know the difference between temperature and heat. 

8.19 Differentiate between exothermic and endothermic changes.

8.20 Know the basic properties of waves, especially those associated with sound and light energy (reflection, refraction, frequency, wavelength, amplitude, etc.)

8.21 Discuss the basic simple machines and the forces and properties associated with each. 

8.22 Identify or calculate ideal mechanical advantage for all simple machines (except the screw).
