What is Matter? NEED TODAY SCIENCE We will categorize objects as matter and not matter and size, location and charge of the 3 subatomic particles.

AGENDA History of Matter N2: What is Matter Rotations: Matter vs Not Matter Videos: AIR and WATER are matter History of Atom N2 cont: Subatomic Particles Subatomic Memory Game Videos 5?Quiz: Matter and Subatomic Particles

Today we will complete…

Presentation Cues No one wants to listen to the teacher the whole time;) Volunteer/Class Discussion – quick answer from raised hand (remember/understand) Pair/share – quick chat with neighbor and volunteer or teacher pick share (remember/understand/apply) Group task – longer time for pair or group to apply, analyze, evaluate or create Individual write – personal reflection on topic Rotations – solve the station with group and write answer on paper, rotate with timer and stay with your group 5?Quiz – quick check for understanding about topic

Let’s see what you know… What is MATTER? What are ELEMENTS? What are ATOMS?

Greeks spent a lot of time THINKING about what everything is made of… Greeks liked to think! Thales (624BCE) – water Anaximander (610BCE) – limitless Anaximenes (585BCE) – air Heraclitus (535BCE) – fire Empedocles (490BCE) – 4 elements – earth, fire, air, water Aristotle (384BCE) – 4 elements plus aether (substance that fills the void above earth) Matter is real because it has form

The guys who figured it out… Each person added a little more to the knowledge of matter Democritus (460BCE) – matter made of small tiny particles Descartes (1596) - matter is a substance, takes up space Newton (1643) - matter has mass, made of impenetrable particles Priestly (1733) – matter has power of attraction

Has mass (can be weighed) Has volume (takes up space) What is Matter? Made of atoms Has mass (can be weighed) Has volume (takes up space) Can be solid, liquid or gas

If you can answer “YES” it’s MATTER! Rotation Stations “Can I weigh it?” “Does it take up space?” If you can answer “YES” it’s MATTER! Make a t-chart in your notebook like below. As you rotate, write the object in the proper category MATTER NOT MATTER

Rotation Stations 11 4 At each station, write the name of the object in the MATTER or NOT-MATTER column in your notes. We’ll practice the first 3 together 10 5 6 9 7 8

1. Are DOGS matter? Yes Has mass and takes up space

2. Are FEELINGS matter? No No mass, doesn’t take up space

3. Is PLAY-DOH matter? Yes Has mass and takes up space

4. Is LIGHT matter? No No mass, doesn’t take up space - Pure energy -

5. Are TOYS matter? Yes Has mass and takes up space

6. Is FIRE matter? No No mass, doesn’t take up space - Pure energy -

7. Is WATER matter? Yes Has mass and takes up space

8. Is SOUND matter? No No mass, doesn’t take up space - Pure energy -

9. Is METAL matter? Yes Has mass and takes up space

10. Are CHILDREN matter? Yes Has mass and takes up space

11. Is AIR matter? Yes Has mass and takes up space (this one is hard for students to believe – to prove – weigh an empty balloon. Then blow it up and weigh again, the mass will go up (albeit minutely)

MATTER NOT MATTER

Are Fire and AIR Matter? Crash Course Kids Millsium – Is fire matter? https://www.youtube.com/watch?v=ELchwUIlWa8 Millsium – Is fire matter? CramBoom – Air is Matter https://www.youtube.com/watch?v=-YQT9pUWrJw

What are ELEMENTS? Substances which cannot be broken into simpler ones Each one is made of the same kind of atom

Where is information about ELEMENTS located? Periodic Table tells us about the 118 different kinds of atoms that make up the 118 different elements https://www.youtube.com/watch?v=Uy0m7jnyv6U

Is AIR an ELEMENT? NO – NOT ON PERIODIC TABLE Made of many different kinds of atoms

Is CARBON an ELEMENT? YES – ON PERIODIC TABLE Made of only carbon atoms

Is WOOD an ELEMENT? NO – NOT ON PERIODIC TABLE Made of many different kinds of atoms

Is PLASTIC an ELEMENT? NO – NOT ON PERIODIC TABLE Made of many different kinds of atoms

Is OXYGEN an ELEMENT? YES – ON PERIODIC TABLE Made of only Oxygen (O) atoms

Is EARTH an ELEMENT? NO – NOT ON PERIODIC TABLE Made of many different kinds of atoms

Is POTASSIUM an ELEMENT? YES – ON PERIODIC TABLE Made of only Potassium (K) atoms

Now you….

Matter is made of atoms! ATOMS are the smallest complete pieces of matter in the universe. Dalton – small sphere Thompson – has positive and negative charges Rutherford – nucleus Bohr – energy levels Schrodinger – electron cloud

What is an Atom? Atoms are the smallest whole piece of matter Two areas: Nucleus – inside Has all the mass Electron Cloud – outside Determines reactivity

Draw this under your t-chart... + + -

3 Subatomic Particles: Proton Neutron Electron Charge Size Location Use the information from the following slides to complete the table…

PROTON Positive charge 2000x larger than electrons Located in Nucleus - + + - PROTON

NEUTRON Neutral charge 2000x larger than electrons Located in Nucleus - + + - NEUTRON

ELECTRON Negative charge 2000x smaller than protons/neutrons Moves around in Electron Cloud Can leave atom to make new substances - + + - ELECTRON

SUBATOMIC MEMORY GAME PLACE ALL CARDS WITH “SUBATOMIC MEMORY” SIDE UP First student flips 2 cards over If you pick up 2 vocab words, 2 descriptions/pictures OR one of each that doesn’t match = FLIP THEM OVER NEXT STUDENT GOES If there is a VOCAB WORD (PROTON, NEUTRON, ELECTRON) and a picture/description that matches = KEEP THE CARDS GO AGAIN UNTIL YOU GET NO MATCHES WINNER = MOST CARDS Subatomic memory cards should be printed double sided on card stock, cut and placed in baggies Make sure to model how to get a “match” so that they understand how to play Could also be done as a matching game or sort

Even though true, not match for game + + + + Even though true, not match for game + +

Print this slide on back of following 2 slides
