WUP – STAAR Review Guide

7. Students put two ice cubes on separate plates. One ice cube had a mass of 80 grams while the other had a mass of 40 grams. Which result would be the same for both ice cubes in this investigation?

A. The time it took each ice cube to melt completely

B. The temperature at which each ice cube melted

C. The amount of liquid produced on each plate

D. The total volume of each ice cube

TOC = Objective: Day 3 & 4

I will be able to compare:

a) rotation to revolution

b) solstice to equinox

TOC = Rotation vs Revolution

MOVEMENTS

## EARTH'S ROTATION AND REVOLUTION

### Earth’s Rotation

• Rotation is the spinning of the Earth on its axis.

• The time for one rotation is 24 hours.

• (t is for Top, to spin)

• Hokey Pokey

### Earth’s Revolution

• A revolution occurs as the earth moves around the sun.

• Time for one revolution = 365 1/4 days = 8,766 hours

• The speed of earth’s revolution is about 18 miles per second.

• (o is for orbit) Touchdown

### Around and Around We Go

• Every second, that you sit in this classroom, the Earth's orbital motion carries you about 18 miles through space.

TOC = Equinox vs Solstice

Setup page for notes.

The Vernal (Spring) Equinox (about March 21): Where the Sun crosses the equator going from south to north.

The Autumnal (Fall) Equinox (about September 21): Where the Sun crosses the equator going from north to south.

### Solstices

• The Summer Solstice (about June 21): Where Sun is shining furthest north on Earth.

• The Winter Solstice (about December 21):Where Sun is Shining furthest south on Earth.

### Solstice & Equinox
