Study Notes

Materials

Materials are used to make things around us
Different materials come from plants, the earth, and animals, or are man-made
Seven main material classes: wood, rock, metal, plastic, rubber, glass, fiber

Wood

Comes from trees
Hard
Used for houses, furniture, paper, and boxes

Rock

From the Earth's crust
Hard and strong
Includes stone, clay, and sand

Metal

From the Earth's crust
Hard, strong, and shiny
Can be shaped and bent

Plastic

Made from petroleum
Light, flexible, tough, and can be brittle
Used for kitchenware and electrical appliances

Rubber

Obtained from rubber trees
Elastic and soft
Cannot withstand heat
Used for tires, erasers, and balls

Glass

Obtained by heating sand and limestone
Transparent
Breaks easily
Used as windowpanes, glass bottles, and light bulbs

Fiber

Comes from cotton, jute, wool, and silk
Used for clothes, carpets, canvas, curtains, ropes, and school bags

Types of Materials

Natural materials: found naturally (e.g., logs, sand, rocks)
Man-made materials: made from natural materials (e.g., glass, plastic, paper, nylon)
Flexible materials: can be stretched, bent, twisted (e.g., erasers, rubber bands, gloves)

Material Changes

Heat can cause changes in materials
Temporary/Physical Change: the material changes state (solid, liquid, gas) but can go back (e.g., ice melting)
Permanent/Chemical Change: the material changes into a new material and cannot go back (e.g., wood burning)

Forces

A force can make things move or stop moving things
Simplest forces are push and pull
Forces can be large or small
Examples of forces: pushing, pulling, lifting, stretching, twisting, squeezing, pressing, bending
Forces can:
- Start an object moving
- Speed up a moving object
- Change the direction of a moving object
- Slow down a moving object
- Change the shape of an object
- Change the size of an object
- Rotate an object
- Stop a moving object

Types of Force

Muscular Force: force produced by muscles (people or animals)
Electric Force: force produced by rubbing (e.g., comb on hair attracting paper)
Magnetic Force: force used by a magnet to attract certain materials (e.g., iron nails)

Plants

Plants are living things needing air, water, food, and light
Many kinds of plants, some big, some small
Plant types: shrubs, herbs, creepers, trees
Plants grow in different places – land, water, even on buildings
Plant groupings: flowering plants (bear flowers, most fruits & veggies) and non-flowering plants
Plant parts and functions:
- Roots: absorb water and minerals
- Stem: transports water and minerals
- Branches: support flowers and fruits
- Leaves: make food through sunlight
- Flowers: produce new young plants
- Fruits: have seeds, protect seeds, seeds grow into new plants

Animals

Animals are grouped: by features, food, movement
Vertebrates: animals with a backbone (e.g., fish, amphibians, reptiles, birds, mammals)
Invertebrates: animals without a backbone (e.g., worms, spiders, insects)
Animal food groups: carnivores (meat), herbivores (plants), omnivores (both), insectivores (insects)
Animal movement: legs (running, crawling, climbing), wings (flying), fins (swimming), bodies (crawling, creeping), arms and legs (climbing, swinging, walking, running)
Food chains: show how living things get food & energy flows from one to another, starting with plants and ending with animals
Predator: an animal that hunts other animals for food
Prey: an animal that is hunted by a predator for food
