Go BACK to ISN page 71, The Water Notes & ADD THIS:#5. Water EXPANDS upon freezing, making it less dense, so it FLOATS!

1. Solution = a mixture of 1 sub. dissolved in another so properties are same throughout composed of a solute and the solvent. ...

2.2. SoluteSolute = being = being dissolveddissolved

3.3. SolventSolvent = doing = doing dissolving – in dissolving – in LARGER amountsLARGER amounts

ISN p.76ISN p.76CARBON Notes CARBON Notes • It is the ubiquitousubiquitous architect,

builder, & basic building material of basic building material of lifelife.

1. Organic = contains Carbon2.2. Chemical basis Chemical basis for all molecules in

living things.3.3. VelcroVelcro that holds, frees, & remakes

the molecules of life.4.4. Molecular scaffold Molecular scaffold of every living

creature, & all of the dead ones, too!• Required almost every stage of development Delivers stored energy to cells. DNA is written in a carbon script. Every part of body contains & requires large amounts The oil in our hair, the fat in our gut, skin, & other tissues are made of it Used as building block for many complex & important life processes. Carbon in our bodies brings the many diverse atoms together & makes them perform activities that benefit growth in a cohesive manner!
