SCI 5: July Exam (L1 - L2 Matter)

Lesson 1 – Properties of Matter

General Properties – observed in a phases of matter
Special Properties – unique property of o phase or kind of matter

General Properties:
1. M – amount of matter in an object
2. Ve – amount of space occupied
3. Dty – mass per unit volume, determines if the matter will sink or float.

Measuring volume:
1. Rectangular solid = definite shape, > length X wh X height
2. Irregular Solid – no definite shape > sink in wa in graduated cylinder

Special Properties of Solids:
1 Sh – regular and irregular solids
2 Co -
3 Tex – how the object feels
4 Ler – ability to reflect light
5 Pity – to hold or absorb Liquid
6 Mity – hammered into sheets
7 Dity – to transformed into wires
8 Bness – to break
9 Fity – to bent without breaking
10 Civity – allows heat and electricity to pass through
11 Elity – return to original shape after stretched

Special Properties of Liquids:
1. City – to pass through small fine tube
2. Fity – to flow
3. Vity – to resist flowing

Special Properties of Gases:
1. Dibility – to spread out faster
2. Cibility – to fill its container and takes its shape

Uses of Properties of Matter:
1. Food Products
a. Nl - farm
b. Ped – lasts longer
2. Cosmetics and Medicines
a. Cs – make a person more visually appealing
b. Ms – cure or treat an ailment
3. Hhold Products

Extion date – tells when the product is at its best quality

5 Rs of Waste Management
1. Re – use less products
2. Re – pass to others for use
3. Re – use to make something new
4. Ret & Resity
5. Rek & Rete

We Sion - practice of separating waste materials into biodegradable and nonbiodegradable

Biodegradable – capable of dy
biodegradable – do not decay
Product Hazardous Warnings:
1. Pous or Tc – may be lethal or may cause serious irreversible effect
2. Cive – causes burns to the skin, eyes, and lungs
3. Fmable – burns easily

Lesson 2 - Changes in Matter

• cal Change – change in physical appearance
• cal Change -forms new matter
• cosion - gradual wearing of metal by combining it with nonmetals
• Ht - flow of energy from warmer to cooler area
• Temture - degree of hotness or coldness of matter, and how ft its particles move
• Thal Exsion - increase in volume because of heat (object grows)
• Thter - tool used to measure temperature in units called Des
• Heating - object particles moves fer, causing the object to gr
• Cooling - object particles moves ser, causing the object to shrk

Arrangement of particles
1. Solid – very clo
2. Liquid - have spaces in between, and move slly
3. Gas - have so much space in between, moves qly

Lesson 2 - Changes in Matter

Physical Changes -
1. ing - solid to liquid
2. ing or Solidifying - liquid to solid
3. ation - liquid to gas
4. ation - gas to liquid
5. ion - solid to gas ex. dry ice, moothballs
6. Desition - gas to solid ex. frost, snow

Chemical Changes:
1. Silver tishing
2. Bing, Ring, Exding
3. Ding hair or cloth
4. Food Rning and Sing
5. Animal deition
6. Cking of Food
7. Diion of Food
8. Fl Burning - for cars and buses to move
9. Phothesis
10. Fworks display

Evidence of Chemical Change:
1. Change in cor
2. Bus appearance
3. Release of lit and ht
4. Tishing - corrosion of metal causing color change
5. Pretate - soap scum, solid formed from water & soap
