Lesson:

Review Friction Key COncept Builder

SLANT: Friction and the law of conservation of energy

  1. Sometimes friction makes it look like The Law of Conservation of Energy is being broken.

  2. Friction is a force that resists sliding of two surfaces that are touching.

    • converts kinetic energy (motion) into thermal energy.

  3. All surfaces have some friction

    • rough pavement (high friction)

    • ice (low friction)

  4. friction “wastes” mechanical energy

    • lubrication (oil) and bearings) reduce friction

    • make a bike easier to ride

Lesson:

Review energy transformations worksheet from HW

Review Key Concept Builder Worksheet from Do Now

Read and Discuss Text pages 393 and 394

SLANT: Changes Between Forms of Energy and Conservation of Energy

  1. energy transformation: when one form of energy is changed into another

    • examples:

      • electrical into radiant into thermal in a microwave

      • electrical into radiant and sound in a television

      • changes between KE and PE

  2. objects often transform potential energy into kinetic and kinetic into potential

    • throwing a ball upward is a good example:

      • pushing the ball upward gives it kinetic energy

      • as it rises the kinetic is turned into gravitational potential

      • at its highest point all of the kinetic is gone and it is now gravitational potential

      • as it falls, gravitational potential is transformed into kinetic

      • as it strikes the ground or is caught it is maximum kinetic energy again

  3. conservation of energy:

    • the law of conservation of energy states that energy can be transformed from one form into another, or transferred between one area and another, but it is never created or destroyed.

    • The total amount of energy in the universe does not change

    • it hasn't changed since the universe was created in the Big Bang

Do Now:

Take out your notes on Why is Meiosis important and How do Meiosis and Mitosis differ?

Lesson:

Desk Check

SLANT: Why is meiosis important?

  1. meiosis forms sex cells

    • haploid (half of the chromosomes)

  2. when two sex cells join this makes a diploid cell (zygote)

    • diploid cells are body cells and can grow into an organism

  3. big idea! Meiosis maintains diploid cells in sexually reproducing organism.

  4. big idea! Meiosis creates genetic variety in offspring.

    • each sex cell has a different half set of chromosomes from all others

    • Crossing over and random assortment of chromosomes make certain no to sex cells are exactly alike

    • Variety supports health and helps a species adapt when conditions change.

  5. both mitosis and meiosis start with diploid cells – but differ from there

    • meiosis undergoes one division and produces two diploid cells that are identical to the parent

    • this allows growth and repairing organisms

    • mitosis undergoes two divisions and produces four haploid cells that are different from each other

    • this make certain offspring all inherit different genetic information from each other creating variety

Lesson:

SLANT: KINETIC AND POTENTIAL ENERGY

  1. energy is the ability to cause change

    • energy is measured in a unit called the joule

  2. kinetic energy is energy due to motion.

    • It is affected by speed and mass

    • as speed increases so does kinetic energy

    • as mass increases so does kinetic energy

    • examples…

  3. Potential energy is energy that is stored due to interactions between objects or particles.

    • Gravitational potential energy: energy stored by the attraction between two object’s due to gravity

    • depends upon mass, the acceleration due to gravity, and height

    • weight is mass x gravitational acceleration

    • PE = Mass ∙ Gravitational Acceleration ∙ Height

    • PE = Weight ∙ Height

    • examples…

  4. Elastic potential energy: energy stored in objects that are compressed or stretched

    • rubber band

  5. chemical potential energy: energy stored in chemical bonds between atoms

    • fuels like gasoline and wood

    • food

Independent Work:

Chapter Content Outline - Diploid and Haploid Cells

  1. Organisms that reproduce sexually form two types of cells.

    • sex cell

    • body cells

  2. Body cells have pairs of chromosomes

    • diploid cells

  3. Chromosomes are in pairs because individuals receive similar chromosomes from each parent

    • similar means each has genes for the same trait arranged in the same way on the chromosome

    • homologous chromosomes

    • because they come from different parents they are similar but not identical

    • ex. both might have an eye color genes, but Mom’s might be blue and Dad’s might be brown

  4. All 23 human chromosomes are in homologous pairs

    • humans have 23 pairs of chromosomes (which equals 46)

    • Having the incorrect number of chromosomes leads to a chromosomal abnormality

    • 3 copies of chromosome 21 causes Down Syndrome

  5. Other organisms have different numbers

  6. Sex cells are different from body cells

    • sex cells have half the number of chromosomes

    • only one chromosome from each pair - 23 single chromosomes

    • haploid cells

  7. sex cells are produced by meiosis

Sexually reproducing organisms have pairs of similar chromosomes - pairs because one is inherited from each parent.

Sexually reproducing organisms have pairs of similar chromosomes - pairs because one is inherited from each parent.
