After School 'To Go' Weeks 3 and 4

Week 3

How do different types of black ink react when absorbed by water? Girlstart girls recently explored chromatography-the process of ink dissolving into paper- by marking coffee filters with different types of black markers and putting them in contact with water.  They observed that as each marker came into contact with the water, the pigments that made up the black color dissolved into the filter. Some pigments continued to move with the water as it was absorbed by the filter, while others did not. This occurs because some pigments are more soluble, or dissolve better, and move quickly, while less water-soluble pigments move slowly.

Parallel Circuits

In continuation of last week, the girls reviewed complete circuits with the inclusion of a hand made light switch. They discussed that a series circuit with atleast two light bulbs need the electric current to go through all components at one time.

Hands-On Wednesday

Solar Eclipse

The moon phases are caused by the moon's orbit around Earth. Every 29.5 days the moon goes through all of it's phases, and from Earth the moon appears to change shape and size in the night sky. The New Moon phase appears completely dark to us, because the moon is between the Sun and Earth. This means all the sunlight is lighting up the side facing away from us. Sometimes, when the alignment of the Sun, Earth, and moon is just right, the moon blocks out part of the Sun! This is called a solar eclipse, and can be a total eclipse or a partial eclipse.
