Observing the Force of Gravity

How can gravity be measured?

How would the pull of gravity change on a planet of a different size?

Drop it:  Fight Gravity!

Drop a piece of flat paper and a crumpled piece of paper at the same time. 

Did gravity affect the objects in the same way?  Explain

Lessons in Motion

Metric Measuring

Where would you find 1 Million Meters?  

Hint: look on the earth, or watch the video from the last blog.

From Small to 

LARGE!

Millimeter  mm

Centimeter  cm

Meter m  

Kilometer km

Write them like this:

Millimeter   30mm 34 mm

Centimeter   3 cm 3.4 cm

Meter m   1m   1.3m 1.33m

Kilometer km We'll leave this for another day...

   

What does a scientist use to measure?

How do people measure length?

What will we measure?

How will we talk about movement?

 Students will start exploring the ways motion can be observed and measured.  Many had requested seeing the "Cloud in the Classroom" lesson from last year.  This was a great opportunity to watch movement and begin our vocabulary.

Describing the movement of clouds.

 2HY strength of movement, straight, force, friction, motion, position, gravity and wind, diagonal, back and forth, in a circle, speed, up and down, crooked, distance, float, fast, quickly, pulled push throw, curve and turn, gentle,side to side, spinning twirling, twisting.

2H  motion, forces, position, friction, movement, predict where it will go, centimeter, acceleration, meter, curve, straight, around, turn, come together like a couple of animals, twist, spiral, swirly, flipping, bouncing, circling, curvy.

2B
Shooting, pushing pressure, connection, north, south, east, west, high, low, right, left, spiral, whirlpool, squiggly, zig-zag, yard, stable, balanced.
