[Notes Test] SCI 4 - July Exam (L1 - L4)

Lesson 1 – Properties of Matter

Pro –observable characteristics in an object
Ge properties – observed in all kinds of matter
Spe properties – only in certain group

*General Properties:
1. M – amount of matter an object has
2. W – gravitational pull on mater
3. V – space occupied by matter

• Weing s – use to measure weight or mass
• Rr – use to measure volume of objects with regular shape
• Br – use to measure the volume of liquids and irregular shaped solids
• Disment method – measure volume of objects with irregular shape.
• Den – the mass per unit volume of a material
• Cons – materials that allows the flow of heat or electricity
• Nons – cannot withstand heat or electricity
• Buocy – upward force exerted by fluid, opposing the weight of an immersed object

*Special Properties of Solids
1. Hness -
2. Smness – determined by sense of touch
3. Briness – ability to break easily
4. Buocy – ability to resist sinking
5. Conbility – ability to allow the flow of heat or electricity
6. Magism – attraction to magnets
7. Elasty – can stretch and return to original shape
8. Mality – ability to be pounded into thin sheets
9. Poty – ability to absorb and hold liquids

Special Properties of Liquids
1. Flity – ability to flow
2. Visty – quality of being thick and thin, or sticky

*Special Properties of Gas
1. Dibility – ability to spread out or expands
2. Combility – ability to be squeezed in a container.

Lesson 2 – Product Labels and Proper Waste Disposal

Product Labels:
1. Nutnal Fts – amount of each nutrient
2. Ace Ingent – substance that brings the desired effect of product
3. Extion De – until when the product is safe
4. Diions – procedure in using the product
5. Us – what the product is for
6. Wings – cautions regarding possible harm
7. Ine ingents
8. Prot destion

Lesson 2 *5 R’s in Waste Management
1. Ree – use less
2. Ree – donate old things, or keep for younger siblings
3. Ree – process used or waste materials into a new product
4. Rest – follow local ordinance on how to dispose trash properly
5. Resity – practice waste management

Lesson 2 – Product Labels and Proper Waste Disposal

• Peable – materials that spoil easily (meat, fish, fruits, veges)
• Flable – materials that can burn easily
• Corive subce – destroys and damages other substance
• We Mament – collecting, transporting, disposing, and managing of waste materials
• Recle wae – waste that can potentially recycled
• Segion – process of separating waste materials into biodegradable and nonbiodegradable
• Bioable mials – waste that can decay (kitchen and food waste)
• Ndegradable mates - permanent garbage, do not decay or decompose (plastics, tin cans)

Lesson 3 - Changes in Matter

TERMS:
• Phal Chae -change in size, shape, state of matter – change in physical appearance
• Cheal Cge – brings about a new material with different properties
• A – produced after a material is burned

PHYSICAL CHANGES:
1. Ming - solid to liquid
2. Fing - liquid to solid
3. Evion - liquid to gas – water vapor
4. Coation - gas to liquid – clouds formation
5. Suation - solid to gas – dry ice, moothballs
6. Detion - from gas to solid – frost, snow formation

Lesson 3 - CHEMICAL CHANGES:
1. Rning – chemical change that happens in fruits
2. Ring – chemical change that happens in iron
3. Sing – happens in fruits that is not consumed
4. Bing – turns matter into ash and carbon dioxide
5. Dion – absorption of food nutrients
6. Phthesis – plants making food

Evidence of CHEMICAL CHANGE
1. Release of lit and he – burning
2. Fizng or gs formation – antacid, airborne tablet
3. Cor Change - Fruit ripening, iron rusting, hair dying
4. Tae, odr and smll change - fruit ripening and decaying/spoiling –

Lesson 4 - Useful and Harmful Effects of Change

Useful or Beneficial Effects:
1. Cls - collected water vapor in the air that transformed to liquid form because of temperature change
2. Rn - nature’s way of watering plants
3. Phosis - food making process in plants
4. Food Dion - breakdown of food to different nutrients needed by the body

Lesson 4 - Harmful Effects
1. Fld - caused by Too much rain
2. Ad Rin - rain reacting with chemicals from smoke belching cars and factories -> harmful to living and -living things
3. Poion - result of addition of harmful materials to the environment -> can cause different diseases
4. Gll Wing - increase in the tempture of Earth, caused by increase in greense gases like carbon monoxide and carbon dioxide
5. Fd Poing - caused by eating spoiled or contaminated food

Bing (garbage, fuels in cars and factories) - produced Carn Diide  -> can lead to Glal Wing when continuously increases
