Math

Today in math, we did mental math 30 and found the average of all of them, then we did that assessment, and then some people worked on accelerated math or the chapter test on page 262.

Today in math class we did mental math 21 and talked about definitions amd wemt over the questions

Today in science class Mr. Maksymchuk showed us some programs for atoms. Then at 2:00 we started our slide show about the timeline.

Sodium is the 11th element in the periodic table, the abbreviation for sodium is Na because the Latin word for sodium is natrium.

This is a pure substance because it's pure water, and only water.














This is a solution because the salt is dissolved in the water and the properties are still the same.














This is a compound because it's made up of two diferent substances.













This is a homogenous mixture because there all made up of the same particles.

This is a heterogenous mixture because its all different
