Science 1

• Water drops that collect on a cold glass of lemonade come from - the air
• Producers - are organisms that get their energy directly from the sun .
• They are able to turn sunlight into food through a process called - Photosynthesis.
• plants - examples of Producers
• Nitrogen(n2) - the most abundant naturally occuring gas .
• oxygen - the second most abundant gas .
• inert gas - the third most abundant gas .
• carbon dioxide - in the atmosphere is about 0.03
• Plants - use carbon dioxide to make food
• Oxygen - animals breath in.
• Evaporation - the process by which a liquid changes into gas
• Abiotic Factors - are the non living components of an ecosystem
• Biotic factors - are the living components of an ecosystem.
• Carnivores - are animals that eat mainly or exclusive meat.
• Herbivores - are animals that feed on plants.
• Omnivores - are animals that eats both plant and animal matter.
• Decomposers - break down dead organisms, waste products and other organic material.
• photosynthesis - the process in which producers make their own food
• Ecosystem - is a community of interacting organisms and their physical environment
• Heterotrophs - are organisms that cannot make their own food using sunlight .
• Animals are heterotrophs while plants are autotrophs
• heterotrophs - obtain energy by eating other organisms.
• carbon dioxide is released by animals into the atmosphere during respiration which is used by plants to make food through the process called photosynthesis.
• Plants are called producers or autotrophs because they can make their own food through the process called photosynthesis
• Consumers - are organisms that eat other living things (heterotrophs).
• Heterogeneous Mixture - means different,you can see different parts or phrases the mixture easily.
• Homogeneous Mixture - means the same,you cannot see the different parts or phrases of the mixture easily.
• Solute - is the substance that dissolves
• Solvent - is the liquid that does the dissolving
• Solution - a mixture that is the same or uniform throughout,also called homogeneous mixture
• Solubility - solute dissolves easily than others
• Miscibility - a liquids mix well with water or miscible in water but not all liquids can be mixed.
• Colloids - another form of mixture
• Mixture - is a combination of two or more substances or compound.
• Handpicking - the components should be big enough to be pick up by hands.
• Decantation - a technique use in separating less dense substance from the desser one.
• Filtration - it uses filter like mesh cloth or filter proper to seperate.
• Ways of separating mixture 1. hanpicking

  2. decantation

  3. filtration
• solid components fron the liquid

  1. Seiving Shifting

  2. Winnowing

  3. Use of magnets

  4. Evaporation

  5. Distillation

  6. Chromatography
• Seiving Shifting - it can be used in separating big and fine components
