1. Heat
1.1. Is a form energy
1.1.1. Heat gain causes:
1.1.1.1. Temperature gain
1.1.1.2. Matter to expand
1.1.2. Heat loss causes:
1.1.2.1. Temperature lost
1.1.2.2. Matter to contract
1.2. Travels from the hooter reigon to the cooler reigon untill both reigons reach the same temperature
1.3. Conductors are:
1.3.1. Metal
1.3.2. Wood
1.4. Poor conductors of heat are:
1.4.1. Air
1.4.2. Glass
2. Light
2.1. Is a form of energy
2.2. Travels in straight lines
2.3. Can be reflected
2.4. Sources are:
2.4.1. The sun
2.4.2. Fire
2.4.3. Torchlights
2.4.4. LED lights
2.5. When blocked, shadows are formed. The shape of the shadow depends on the shape, size, and height of the object
2.5.1. Shadows vary in size. These are the factors:
2.5.1.1. The distance betwwen the light source and the object
2.5.1.2. The distance betwwen the object and the screen
2.6. Has degrees of transparency. The 3 terms are:
2.6.1. Transparent
2.6.2. Translucent
2.6.3. Opaque
3. Cells
3.1. Also known as organisms,
3.1.1. Are split mainly into 2 groups
3.1.1.1. Plant Cells
3.1.1.1.1. Which have:
3.1.1.2. Animal Cells
3.1.1.2.1. Which have:
3.2. Are the smallest unit of life
3.2.1. And therefore,
3.2.1.1. They make up everything in the whole world
4. Water Cycle
4.1. Goes on and on like this:
4.1.1. Water vapour from our breath, land, animals, plants and lakes/oceans lose heat to the surroundings
4.1.2. Condenses into clouds
4.1.3. When the clouds get to dense, water rains down and the cycle continues forever.
5. Reproduction In Plants And Humans
5.1. Plants
5.1.1. There are 3 'genders' of plants. They are:
5.1.1.1. Unisexual
5.1.1.1.1. Has both male and female parts
5.1.1.2. Female
5.1.1.2.1. Has only the female parts
5.1.1.3. Male
5.1.1.3.1. Has only the male parts
5.1.2. Plant's reproductive process goes like this:
5.1.2.1. Pollen grains are released from the Anther
5.1.2.1.1. The Pollen grains land on the Stigma
5.2. Humans
5.2.1. There are 2 genders of humans. They are:
5.2.1.1. Male
5.2.1.1.1. Has only the male parts
5.2.1.2. Female
5.2.1.2.1. has only the female parts
5.2.2. Humans' reproductive process goes like this:
5.2.2.1. Sperms are being released from the Male's testes
5.2.2.1.1. 1 or more egg cells are produced from the Female's ovaries. They travel the through the Female's Fallopian Tube to the womb
