Hi, I’m ***********. Are you ready to learn about plastics and their affect on our planet?
Download our contest entry form and report your observations. Send it back to us and you’ll have a chance to win cool prizes like a cool Neerg Hall T-shirt or E-Reader. Pretty sweet, right?
So, are you ready? These science experiments will really get you thinking!
Have you ever thought about plastics? You use them every day and in so many ways.
Some plastics you can bend and twist; others you drop and they shatter. Some go into the freezer and they crack, and some need to stay out of the hot sun.
You will need plastic items found around the house that are empty and are no longer needed by anyone in your family. Grab them before they are tossed into the recycle bin.
Record what number plastics they are by locating the recycling sign and look inside.
Take several plastic bottles or containers – such as a pop or shampoo bottle, yogurt or margarine container, and set them on the ground. Now stomp on them!
What do you observe?
Now reshape them as close as you can to their normal form and place them in the freezer for at least an hour.
Take them out, one at a time and give them a
nother stomp! What do you observe?
Does it float or sink?
Take the plastic containers and cut them into pieces and sort them by type. One at a time take a piece from each different type and drop it into a bowl of water and record your results? Does it float or sink?
Finally, locate some of those dreaded plastic grocery bags from around the house. See if you can find some from various stores. Observe 3 differences between the various bags.
Does one look or feel stronger? Make a guess – which one do you think will be the strongest?
Now load them up one item at a time with cans, boxes and other items … until.. oh, no.. it breaks.
Which store’s bag was the strongest? Was it the one you thought?
Take out a lunch baggie and see how full you can fill it. Find items around your house --that you have several of – like socks, tangerines, etc., .and fill the bag up to see how many you can get into the bag.
Does the bag stretch much? And how much does it stretch before it rips?
Plastics do not just bend, twist, and bouncel by chance—nor is their heat resistance property a coincidence.
Lots of science goes into making each type of plastic just right for its intended purpose. All plastics are made in such a way that even when they are no longer being used for their intended purposes, they will remain in the environment for a long, long time.
Really, it takes about 450 years for a plastic bottle to decompose in a landfill, which is where one might think all non-recycled plastic ends up.
Well, I’ve got news for you. Our oceans are full of plastics! YIKES! All that plastic floating around in our oceans not only looks bad and harms wildlife, but puts lots of toxic waste in our waters after being baked in the sun and soaked in salt day after day. All those chemicals that go into making plastics so versatile - well they come right back out again as plastic breaks down.
I know, you thinking, well it takes almost 500 years so no need to worry now. Nah, plastics exposed to sun and salt breakdown much faster than in a landfill--a plastic bag takes only 10-20 years. The water we have now is all the water we will ever have. Together we can keep it clean!
Now, don’t forget to record your observations on your contest entry form and email us back for a chance to win cool prizes. And you can click this cool link to learn more about Earth Day Coalition and how to keep plastic out of our oceans!
