Feb 27 & 28 Homework DueRead & Study Ch. 12. Write 5 things you learned and 5 questions you have Tonights HW Read & Study 12.1-12.4; do #1-7 p. 180 **Grade will be worth 5 points; point per question and 1.5 points given to a randomly selected problem the teacher will grade on CORRECTNESS. Write full Q&A or include the Question in your Answer!** Do NowTake a clicker 5 minutes to find your Energy poster and decide if you want toTake it homeThrow it outOr hang it up If you wish to display your poster in the class, please borrow masking tape from Ms. Bones and display it NEATLY in the room in a place that does not cause a safety hazard or disrupt normal student learning! If you need to borrow tape/glue to repair any parts of your poster that may have been damaged due to group work, please see teacher.In your notesReflect on this poem by Francis Thompson:All thingsby immortal powernear or farto each otherhiddenly linked are.That thou cans't not stir a flowerwithout troubling a star. What do you think this means? Interpret the poem in your own words by writing your thoughts in your notes.

GravityIs difficult to measure in everyday lifeIs something we take for grantedIs the one of the 4 fundamental forces :gravity, electro-magnetism, strong nuclear forces (which hold the nucleus together)weak nuclear forces (involved with radioactive decay weak nuclear forces: are involved with carbon dating, are a source of radioactivity, etc..)

Which is the WEAKEST of the 4 forces?

Countdown10TRUE or FALSE: The Moon has no gravity.

TrueFalseNot enough information to sayIm not really sure

Countdown10TRUE or FALSE: Planets with thin atmospheres have little gravity

TrueFalseNot enough information to sayIm not really sure

Countdown10TRUE or FALSE: Planets distant from the Sun have less gravity than Earth

TrueFalseNot enough information to sayIm not really sure

Countdown10TRUE or FALSE: Space shuttle astronauts are weightless because there is no gravity above Earth

TrueFalseNot enough information to sayIm not really sure

Countdown10Google PHET Gravity and orbitsClick the first linkRun the simulation and complete the Lab Activity Sheet. This is due next class for a grade you will have about 20-30 minutes next class to finish working on this (10 points based on completion)There will also be a graded, individual, 30 point POST LAB next class to assess this lab activity. Action: Earth pulls moon. - What is the reaction? - What is stronger action, reaction, or same?- What Law defends your answer?

Action: Earth pulls moon. What is stronger action, reaction, or same?

Action(Earth pulls moon)Reaction (moon pulls Earth)Same! What law defends your answer?
