Is rust on an old car an example of physical or chemical change?

Physical changes are changes affecting the form of a chemical substance, but not its chemical composition. Physical changes are used to separate mixtures into their component compounds, but cannot usually be used to separate compounds into chemical elements or simpler compounds.

Chemical change. … a usually irreversible chemical reaction involving the rearrangement of the atoms of one or more substances and a change in their chemical properties or composition, resulting in the formation of at least one new substance: The formation of rust on iron is a chemical change.

What is physical or chemical change?

physical change in a substance doesn’t change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.

  • the force exerted on the mass of a body by a gravitational field.
  • the quality of being heavy.

EXAMPLE: “as he came upstairs the boards creaked under his weight”


The quantity of matter that a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field.

How can you use density to determine if an object will float or sink?

Density: degree of consistency measured by the quantity of mass per unit volume.

“Physical Science” uses MATH to solve answers ALL throughout the year.  Those students who have difficulty with basic computation please utilize daily IXL for practice and review. Parents and students here is a quick tutorial for reference.

WELCOME BACK 2018 -2019 School Year!!!!


Hello Everyone!  Welcome back to the 2018 – 2019 school year. This year 8th-grade students will get a chance to take a deep dive into Physical Science. This year the Georgia Department of Education has developed new standards for students to dive into. This doesn’t really change how we do things in Floyd’s 8th Science Department. We are just going to continue with our ‘wow-factor’ as we get our students going this year. Students will learn about the “Nature of Matter”, “Forces & Motion”, “Forms & Transformations of Energy”, “Electricity & Magnetism”, and lastly, the “Nature of Waves”.  Please feel free to contact your child’s teacher if you have any questions, comments, or concerns. We are all here to help.

Your SCIENCE school supplies list for 8th grade:

4 spiral notebooks

2 packs of 3 x 5 ruled index cards

colored pencils

#2 led pencils

2 highlighters (2 colors of your choice)
