Great Gourds!

What better way to celebrate fall than joining the Greensboro Science Center and The Fresh Market for a Pumpkin Palooza?!?!

For the 5th consecutive year, The Fresh Market is graciously donating pumpkins – and tasty pumpkin treats – for Greensboro Science Center visitors to enjoy during Pumpkin Palooza on Saturday, October 18, 2014. This event, which is free with general admission or membership, is filled with all kinds of fall family fun – from games and activities to entertaining animal enrichment and scrumptious snacks.

From 10:00am to 1:00pm, visitors will have the opportunity to watch our animals enjoy some pumpkin fun. It’s always amusing to see just what the animals will do with their pumpkins… play with them, crush them, eat them, swim with them, carve them (okay, maybe not)… Animals will be given their pumpkins at approximately the following times:

Lemur Enjoy Pumpkin Treat

10:15am               Tigers
10:45am               Lemurs
11:00am               Tortoises
11:30am               Fishing Cat
12:00pm               Meerkats
12:30pm               Otters

Animals aren’t the only ones enjoying the autumnal action. Kids will have a great time playing pumpkin and Halloween-themed games like Bag the Bat, Pumpkin Bowling, Ring the Pumpkin, Black Cat Golf and more!

Candy Chromatography

Turn your Halloween candy into an awesome chemistry experiment!

Materials:
Candy with colorful coating
Flat plate or piece of foil
Coffee filter
Water
Pencil
Tape
Toothpicks
Clear glass or jar

Procedure:
1. Cut your coffee filter into a square.
2. In pencil, draw a line about one inch from the bottom of the filter. Using equally spaced increments, write the color of each candy on the bottom of your coffee filter.
3. Place one drop of water on your plate or piece of foil for each colored candy you want to test.
4. Put a piece of candy on top of the water drop and allow it to sit and dissolve for about a minute.

Procedure: Place Each Candy on a Drop of Water

6. Using a clean toothpick for each color, place a small dot of the colored water on your coffee filter about an inch from the bottom above the appropriate color label.
7. Let the drop dry and repeat 2 or 3 more times.
8. Place a small amount of water in your glass or jar.
9. Tape your coffee filter to the pencil and place it over your glass or jar so the bottom of the filter just touches the surface.
10. When the water reaches about an inch from the top of the coffee filter, remove the filter and let it dry.
11. Observe your results!

What Happened and Why?
As the water soaks into the coffee filter, different components of each colored dye are separated. As you can probably see from your results, some colors are made up of a mixture of dyes. You’ll also notice that some colors are pulled farther up your coffee filter than others.

This is all explained by the fact that various dyes have their own chemical compositions, each of which separate at varying rates. Additionally, each chemical therein absorbs different wavelengths of light and by default expresses the ones it does not absorb, meaning that those not absorbed are the colors our eyes can detect.
