Science "In the News" on Plant-based Plastics and Science Literacy

Here is a quote from, "In the News," which I have quoted here because otherwise it changes on a different day. It is provided by The Free Dictionary and on todays date is found in the left hand column.

Using current events is helpful in science classes. I was going to address plant-based plastics because at the canteen in the Everglades, they used cups made from plants and that was exciting. Then, here the plant based plastics are being used for the soft-drink industry.

I am not pushing soda (You must use your own science knowledge and skills to make a decision about soda in your diet, but I am commending the company for moving toward a renewable resource-based bottle. That is a good thing.

Quoted material and photograph follow:

"Pepsi Unveils Fully Plant-Based BottlePepsiCo has unveiled what it claims is the first PET plastic bottle made entirely from plant-based, renewable sources. It is not biodegradable or compostable, but it is fully recyclable. Traditional PET plastic is made using fossil fuels, but the new "green bottle" is made from materials like switch grass, pine bark, and corn husks. In the future, it may incorporate orange and potato peels, oat hulls, and other byproducts from the company's food production lines. By drawing on existing plant waste rather than growing plants specifically for this purpose, Pepsico will be making use of some of the estimated 2 billion tons of agricultural waste produced each year. More ... Discuss"

How can you use an article like this to engage students in science classes?

How can such an article enhance science literacy?

Could you use it to encourage students to design experiments based on the ideas they get from reading it?

Can students find related information to help them make judgements based on facts they find out about these bottles? Or, about sodas (pop)?

Could they speculate on making plastics from different plants?

Note that such an article could also give students career ideas:

"The new bottle looks, feels and protects the drink inside exactly the same as its current bottles, said Rocco Papalia, senior vice president of advanced research at PepsiCo."

Did you ever think of doing research at Pepsi or a company like Pepsi? What kind of company would you like to do research at?

Such open ended questions can start students thinking about the role of science in their lives. It can get them excited about learning more science.


Here are Links to Images and Information on Some of the Sights I was able to see at the Winter Star Party Astronomy Conference 2011

I cannot convey the excitement of seeing the stars the way they appear from the WSP. I linked to images and information found on the web because these links can give you more of a feel for what I was able to see first-hand. (Sombrero Galaxy) (Omega Centauri)
Watching this large, luminous star cluster together with Al and Judi Nagler was an extra special treat. You capture their enthusiasm. (Pleides) (Eskimo Nebula)

"Wishing You Clear Skies and Sunny Days" -WSP 2011

Under development...more coming...

Under development...more coming...

The Winter Star Party
, long anticipated and suddenly gone, puts us back in the mood of waiting for next year's event. Still, while looking forward to next year, we have plenty of time to reflect on the night sky observations and the talks. We've had our, "Omega Centauri Fix," (Thanks, Al and Judi) , the, Best Brownies in the Universe," (Thanks, Micki), and can go back home satisfied that we had such wonderful nights, despite the wind. And as Jack Horkheimer (1938-2010)always reminded us, we can "Keep looking up."

Tippy D'Auria delighted us with, "Amateur Astronomy- Frustrations and Rewards," ...The tales of different astronomers and their observations and tools, told in a way that still makes us feel part of each spell-binding saga.

Sheldon Faworski gave us an insightful historical perspective with. 'Amateur Astronomy - through the Prism of "Sky and Telescope."' Sheldon pointed out that "Sky and Telescope" archives are available at a very reasonable price ...He showed how they would make a great addition to any school or home library.

Alan Friedman's talk, "Catching Sunlight - The Art and Science of High Resolution Solar Photography," brought us the expertise of an amateur whose photographs are featured on NASA websites and in their exhibitions. More details are found at

Warren Keller

Mark "Indy" Kochte

Al Nagler

Donald C. Parker spoke tales of the Gas Giants in, "The Gas Giants put on a Show."

Mike Reynolds' talk, "Are [You] Sure This Isn't Astrology? Crazy Astronomy Adventures from Around the World," culled adventures from over 30 years experience in astronomy...academics (teaching and research), museum work, NASA, writing... Plenty of exciting experiences were shared.

Russell Romanella gave a talk that should call us to action: "NASA - Exploration at a Crossroad." While he spoke from his experience at NASA of all the accomplishments, he also spoke of the shuttle's last missions. Having grown up in the Space Age, Russell Romanella's talk had me glued to my seat.

I will add the following comment outside the scope of what was presented in the talk: Since we live in a Democracy, we have the power and ability to contact our elected representatives in the White House, Senate, and Congress. Space has created innovations, excitement, industries, jobs, and a national focus, a striving to be top in math and science, and many other great things. These are things we need today as much as when NASA started. Let your voice be heard on this matter: Continue our Space Exploration. You can now even, "tweet," the government, so, there's no excuse. From snail mail, to e-mail, to tweeting, and beyond, let your voice be heard.

Bob Summerfield

Keith Venables spoke on, "Preserving Dark Adaptation," and let us experiment, too. He gave us a better understanding of bright lights at night. Take a look at lights all over the World. See if you can put any lights out at night. He spoke to us of a movement to darken the night skies that began in the Netherlands and moved to the UK. He is encouraging everyone the World over to join the Dark Skies movement.

Dan Joyce is greatly appreciated for teaching the skills of mirror grinding needed for reflecting-telescope-making.

In addition, we were able to have informal discussions with ...
Matt Baum
and Al Nagler who both worked on the flight simulators NASA used to train the Apollo astronauts for their safe flight to the moon and back, that is, their safe flight, descent, ascent, rendez-vous, and, what we all waited for on the edge of our seats, the return home. Matt worked on the electronics, especially the cameras and displays, while Al worked on the necessary optics.

Winter Star Party Teaching Ideas

Post under development
Come back later

Here is a review of the posts on the 2010 trip to the Florida Keys to see the stars and get some teaching ideas. I want to link them here and review them before posting new ideas from the WSP 2011.

A reader left this comment. It is listed below, but I thought more people might see it here.

For younger kids, especially when outdoors, the 'toilet paper' universe is fun activity that is designed to show just how distant the planets and nearest star are. I have used this a number of times with younger scout troops, and it works well.

Botany Meetings coming Soon; Register Now!

Botanists from around the globe will meet at the 2011 BSA meetings in St. Louis. School teachers are especially encouraged to attend. Scientists get together and provide exciting opportunities for teachers to keep current in science and for them to understand research better by talking directly with the researchers.

Here's a video invitation. There's a fair amount of, "hype," in the video, but, the meetings are a great place to be.

Here's a link to the Botanical Society of America's website so you can register:

Astronomy from the Keys...

Here are a few pictures taken at the, "WSP." More posts following the astronomy Winter Star Party coming soon!!!! Interesting talks were presented and I will discuss some ideas I got that can be applied to activities for students.

Note, that the 'scopes I looked through the most, are those of which I didn't take photographs. Maybe that was because the night sky images I was seeing were so exciting. Or, maybe I didn't see palm trees and ocean in the background (We had these nestled in a relatively wind-free area between a row of cedar trees and two or three camper trailers and trucks... to give fantastic viewing of the night skies...More on these telescopes later!)

I did take these pictures on the way to Micki's Kitchen, the canteen at the Winter Star Party, and the source of the best brownies in the Universe. Lucky for me I am not a chocolate fanatic since these brownies are hard to pass up even if you only like chocolate a little... But, if you crave chocolate...You are in the right place. (I'll look for Micki's Kitchen's contact information in case you need to send anyone a care package and I'll add it here.)
