Composting lab

Composting lab!! 

(This is in English so parents can help kids get ready!)

What you need to bring from home:

• Large clear glass jar with a lid (pickle jar, canning jar, etc.) 
• One item you think will compost (must fit in the jar) 
• One item you think will not compost (must fit in the jar) 
• One item you aren't sure will compost (must fit in the jar) 

It will be interesting to see the results!!


More information:

• See about Beaumont's Keep It Green program here
• See the lab from previous years here. We will modify by using clear jars. 

Here are some videos to get us ready!

• Composting for kids
• How compost is made cartoon

Keep it Green Beaumont!

I have been doing some research about what kind of green initiatives and waste management our town has and I am VERY impressed.  

I had the kids do a garbage sorting activity including where to sort:

• compost
• recycle
• bottle depot recycle
• garbage
• garbage dump (large items, hazardous waste and e-cycling technology)

The town also offers a great deal of information and support.

• Environmental Services (energy conservation, idle-free, water conservation, etc
• Environmental Master Plan (pdf)
• Kids version of the EMP (pdf)
• Curbside collection program (details about sorting garbage)
• Curbside collection program brochure (pdf)

Also have a look at these videos

• Edmonton Waste management Playlist
• Edmonton IPTF and Compost Facitlity

This video is more appropriate for grade 7 kids, not grade 4

Beaumont, we have a problem!

We have had quite a unique experience to follow this week. One of Canada's very own astronauts, Jeremy Hansen, has let us tag along on his adventures in training for a future mission in space. I have had a lot of kids turned on to science and wanting to be astronauts when they grow up.  Amazing!!

NEEMO 19 team getting ready for their last day aboard Aquarius

Jeremy has been spending a week as a member of NEEMO. "NEEMO is a NASA mission that sends groups of astronauts, engineers and scientists to live in Aquarius, the world's only undersea research station, for up to three weeks at a time. The Aquarius habitat and its surroundings provide a convincing analog for space exploration" - NASA

"Back alive with all body parts! Night dive as cool as expected. Luminescence, feeding frenzy, squid..." - JH

Before he spent his week under the sea he put a shout out for simple experiments to do, both at sea level and 19 meters below the surface of the ocean near Key Largo, Florida.  See more about it and the lab we challenged him to try HERE.

  

He accepted our challenge and gave it a try on the surface before going into the deep.  See all about it HERE.  

The results were not at all the same as they were here in Edmonton.  This prompted great discussion about the scientific method and variables that may have altered the experiment.  I always tell kids that science is a process and most of the time your results are inconclusive but lead to refining the experiment and coming up with an even better plan.  

Yesterday he gave our experiment a go while aboard Aquarius with almost three times the atmospheric pressure pushing down on them!!  Here is what he discovered.

@AmandaGMerriman Gum Bear exp. Have some explaining 2 do. Sea H2O left,Fresh right.Fresh fm 20mm to 17mm in 2hrs. pic.twitter.com/PnLQfekmq7

@Astro_Jeremy I guess they don't make gummy bears as tough as we do in Canada. One more variable to discuss with my class.

— Alberta Sci Teacher (@AmandaGMerriman) September 13, 2014

@Astro_Jeremy Thank you so much for trying. Enjoy the rest of your time "under the sea".

— Alberta Sci Teacher (@AmandaGMerriman) September 13, 2014

@AmandaGMerriman scientific method not strictly followed but same gummy in glass container on surface didn't dissolve, it grew. Px effect?

— Jeremy R. Hansen (@Astro_Jeremy) September 13, 2014

 The scientific process at work!  So now we have to come up with an even better experiment with more controlled variables and see if we can do it ourselves here in Beaumont. 

I sent this blog post out into the Twitterverse and broke the internet.  Seriously my phone went CRAZY with notifications.

Awesome work @AmandaGMerriman ! Just had time 2 read this.Great work taking inconclusive science & turning into great lesson.Wonderful!
— Jeremy R. Hansen (@Astro_Jeremy) September 14, 2014

Thank you again @Astro_Jeremy. Life is full of these teachable moments & this entire process has really brought our lessons to life!
— Alberta Sci Teacher (@AmandaGMerriman) September 14, 2014

Here are a few more pictures Jeremy took while out exploring the ocean.  So cool. 

"This wave of small blue Creole Wrasses surrounded us causing a feeding frenzy of Groupers and Barracuda." - JH

"Oh baby! Night dive time. A taste of what's in store just swam by. What you can't see won't hurt you right..." - JH (Anyone else hear Heart singing "Barracuda" while reading this??)

Now this is just for fun.  William Shatner and Chris Hadfield became Twitter friends while Hadfield was aboard the ISS last year.  Jeremy Hansen was trained and gave ground support for Hadfield and his mission.  So from science fiction to science fact, this is just funny ...

As if this place isn't cool enough... We have Star Trek doors! Eat your heart out @WilliamShatner https://t.co/2WPYKX4vqC

.@or_Maggie We are trying to relay the synchronized swimming answer to Jeremy to see if they can do it! ;) http://t.co/b3hK7DctAO

@NASA_NEEMO @or_Maggie That would be the cherry on top of this amazing week!
— Alberta Sci Teacher (@AmandaGMerriman) September 13, 2014

 NEEMO Mission 19 has wrappped up and the aquanauts had to decompress for 16 hours before coming to the surface.  So what do you do for 16 hours?

@Astro_Jeremy @ReefBase what did you all do for 16 hours?!
— Alberta Sci Teacher (@AmandaGMerriman) September 14, 2014

@AmandaGMerriman @ReefBase good ? Debriefs, cleaning, slept, packing, sharing stories & a bunch of laughing. Time 4 reflection as well.
— Jeremy R. Hansen (@Astro_Jeremy) September 14, 2014

What a great week in science!!!!!

NEEMO 19

We have been following Canadian astronaut, Jeremy Hansen, during his astronaut training.  His latest adventure is with NEEMO 19 aboard the under-water capsule, Aquarius.  Read more about it here.

You can view live action webcams both inside and outside of Aquarius here.

Today there was a Google+ hangout where they answered questions, a few of mine included.  I am Alberta Sci Teacher on Twitter and one of my questions is answered around 6min 30sec.  

See more details here.

Very cool week!

@Astro_Jeremy wr were wondering how you get in and out. Cool
— Alberta Sci Teacher (@AmandaGMerriman) September 10, 2014

@Astro_Jeremy @Astro_Andreas Thank you for the video. Now to demonstrate it to my class using my fish tank and a cup!
— Alberta Sci Teacher (@AmandaGMerriman) September 10, 2014

@Astro_Jeremy @Astro_Andreas - The perfect way to explain it. Every kid in my class asked "Why doesn't it fill up with water?". Merci!

NEEMO

My science classes have had some pretty amazing opportunities over the past two years.  One of the highlights of last year was Skyping with Major Jeremy Hansen on Earth Day. (See more HERE).

With a new start to the school year my students have been diving into learning about the scientific method.  We have been learning about Jeremy Hansen's training in preparation for an amazing adventure under the sea with NEEMO (NASA Extreme Environment Mission Operations).  

Jeremy put a call out to people to come up with some experiments he can do "under pressure".

@Astro_Jeremy @csa_asc My class has come up with a few good ideas! We will be sending you them ASAP! Do you have gummy bears under the sea?

— Alberta Sci Teacher (@AmandaGMerriman) September 5, 2014

@Astro_Jeremy @AmandaGMerriman @csa_asc Some of our more hardy divers have already been diving there! #Gummy pic.twitter.com/SGGKaq6T8N

Click on this photo to see the video request he made.

Last year we did an experiment using gummy bears to demonstrate osmosis.  Please click HERE for more details about the experiment and osmosis.)  

My students wanted to take it one step further and find out if the rate of osmosis is different when the experiment is performed under the sea, at sea-level, and maybe one day even up aboard the ISS.  

So here is the experiment.  We measured the length of a gummy bear and then placed it in a baggy of water.  I normally do this in a petri-dish or bowl but we were thinking that if this experiment to be run with as little equipment as possible.  We measured the bear every half an hour for a three hour period.  If I were to do this again I would perhaps measure once an hour for half of a day.  We decided to only do the experiment with tap water instead of both tap water and salt water because it would make it more complicated to do aboard Aquarius, although the results would be interesting.  Finally we would compare the growth/size of our observations here on dry land and on Aquarius after the same amount of time.  

  

After 2 hours

After 3 hours

Our hypothesis is that the rate of osmosis will be greater (faster) aboard Aquarius due to the difference in pressure (despite it being regulated for those aboard).  If it were to be done, hypothetically, on the ISS we would hypothesis that the rate would be slower due micro-gravity and the lack of pressure (despite it being regulated for those aboard).

The applications of these observations are important as we use these concepts when we look at agriculture, water purification, and the needs to the human body.  These are all vital to learning how to expand our reach into the universe.
