8.11 Warm up – Find dv/iv
  • Esther became interested in insulation while her parent’s new house was being built. She decided to determine which insulation transferred the least heat. She filled each of 5 jars half-full with water. She sealed each jar with a plastic lid. Then she wrapped each jar with a different kind of insulation. She put the jars outside in the direct sunlight. Later, she measured the temperature of the water in each jar.

learning goal classify mixtures as being homogeneous or heterogeneous
LEARNING goal:Classify mixtures as being homogeneous or heterogeneous
  • 1 can compare the different types of mixtures
  • I can explain the different types of mixtures
  • I know about mixtures
  • I need to review mixtures
what s the big deal about mixtures
What’s the big deal about mixtures?
  • Designers have to research their materials and products when coming up with new products.
    • They look at the chemical and physical properties
  • Engineers use this in creating new materials, structures and devices
  • In the biomedical field, they have to be aware of how materials would or would not interact with the body
review matter
Review Matter
  • What are the 3 states of matter?
  • SOLID, LIQUID GAS

review matter1
Review Matter
  • What is matter made up of?
  • Elements
    • Pure substance that cannot be broken down into any other substances
    • Simplest substances
    • Identified by certain chemical & physical properties
  • Ex:
      • Gold
      • Aluminum
      • Zinc
      • Oxygen
elements
Elements
  • Particles of elements = atoms
compounds
COMPOUNDS
  • When 2 or more elements are chemically combined to form a pure substance
  • Usually has properties different from the original element properties
  • EX:
    • H2O
    • H2O2
    • NaCl
mixtures
Mixtures
  • What is a mixture?
  • A mixture is when two or more different substances are mixed together but are not combined chemically
  • There are 2 types of mixtures
    • Heterogeneous – hetero = different / geeous = kind
    • Homogeneous – homo = same / geneuos = kind
mixtures1
Mixtures

HETEROGENEOUS

HOMOGENEOUS

A mixture that has different components that can be seen with the human eye

Ex:

Trail mix

A mixture that has the same composure throughout

Different parts cannot be seen

Ex:

Salt water

come up with 3 more mixtures each
Come up with 3 more mixtures each

  • Describes, talks about it’s ability to…
  • Can be physical or chemical
  • Physical property: characteristic/ability of a substance without changing it to something new
  • Chemical property: characteristic of a substance that doeshave the ability to turn into something new

  • Each person makes 6 cards with key words we’ve learned from this whole year
    • Measuring, lab safety, experiments, mixtures…
  • Put all the cards in the center of the table
  • Person #1 puts a card on head and the group tries to explain the card without telling them any part of the actual word.
    • Ex: Dependent Variable – you couldn’t say it’s the opposite of independent
  • 30 sec to get as many cards guessed
  • Count how many you had
  • Reshuffle – person #2 goes…
