What you need today: • Your lab notebook • Label your entry: – Notes on Atoms – Be sure to date and # your page – And add entry to your Table of Contents

Warm-up: • Besides energy, what else moves through ecosystems and how does move?

Lesson 1: What is an Atom? What Makes up an Atom?

What IS an Atom? • Smallest particle of an element • Made of even smaller particles • All matter (solid, liquid, gas) in the universe is made up of atoms • Atoms can ‘lock’ together to make larger molecules – Carbon is like the duct tape of atoms!

What IS an Atom? • Smallest particle of an element • Made of even smaller particles • All matter (solid, liquid, gas) in the universe is made up of atoms • Atoms can ‘lock’ together to make larger molecules – Carbon is like the duct tape of atoms! • Write a 2 sentence summary answering the question: What is an atom?

Let’s talk about Carbon

Build-an-Atom • Alright, so let’s look at one of these Atoms ‘looks’ like • http: //phet. colorado. edu/en/simulation/build -an-atom

Atoms have personalities • Some atoms are social. Some are loners. It all depends on the electrons. – Atoms bond because atoms like to be in stable relationship • Atoms hook up with other atoms by SHARING ELECTRONS

Atoms have personalities • Some atoms are social. Some are loners. It all depends on the electrons. – Atoms bond because atoms like to be in stable relationship • Atoms hook up with other atoms by SHARING ELECTRONS • Based on the periodic table, can you predict which will be loners? Which will be social? What’s the clue?

What you are doing now: Build-an-atom in small groups • Rules for working today: – Your groups will be • One person you often work with • 2 people who you don’t often work with – Everyone works the controls • You will complete the illustrations, notes, and answer the questions in your lab notebook – This is stamped today Start on the molecule activity (due tomorrow)
