(Yes, your host is a child of the 80’s and “The Facts of Life”)

Diana is learning the back and forth, up and down, of life as an interpreter and exhibit developer at the VC:

“Over the past couple of weeks, some interesting things have happened at the Hatfield Marine Science Center.  Not only have people been rude, but they have also been spectacular.  My faith in the human race is always moving back and forth like a wave.  First of all, there is my erosion wave tank.  We have had some great success and devastation in the wave erosion tank.  The wave tank was first somewhat of a chaos area with children walking on the edges of the prototype wooden table, sand volcanoes in the middle of the tank, and water everywhere you can think of around the tank area. Then we made a beach erosion challenge, with signs that gave very simple directions on what visitors were challenged to do. That made a significant difference between the actions taken around the tank area.  We saw a significant increase in families using the wave tank area as opposed to children creating sandcastles on their own as well as an increase in people reading the signs and trying to do the beach erosion challenge instead of just creating waves.  While the increase was promising, I still saw some problems.

One of the main problems of the wave tank that all of us in the VC are seeing is that the water needs to be changed constantly. I have changed the water about 3 times a week and each time there is something new in the water.  I have found potato chips, granola bars, and hair in the wave tank.  A spring broke on the wave creator, and the aluminum is oxidizing from the fresh water, which will lead to more problems later on.  Yet, out of all of these the ongoing problem that is really hard to find a solution for is the amount of water on the floor.  This problem has not only seemed to stump me, but my coworkers and advisors as well.

Out of all of these problems that my project has had, many amazing things have happened as well.  I have had some spectacular conversations with visitors.  This older couple one day came on my estuary tour and first asked some highly intelligent questions that tested my knowledge to the limit.  Then, once the tour was over, I was able to have them stay until closing with our eye level tank feeding, ocean quest and exhibits in general.  They would call me and McKenzie out by name just to ask us questions.  The older man told me he had no previous knowledge about marine science or biology for that matter, so he had many questions.  Oh he did and we had plenty of answers.  The visitors who are rude sometimes make me very upset, but then there are people like this older couple for example and most children, especially the ones that ask tons questions, that make my job totally worth it!”

Wading in to visitor research

Here’s an update from intern Julie Nance as she wades in to gathering data from the public:

“Last week I began front-end evaluation – talking to people out in the Visitor Center to get their opinions for the climate change exhibit.  I had them choose what case study they would want to learn more about, from a set of 14 pictures (species affected by global warming such as salmon, pteropods, etc).

 

I wrote down what everyone said and came up with some interesting trends, such as how the majority of women in their 20’s and 30’s as well as school age girls chose the emperor penguin over the rest.  This wasn’t a huge surprise given the options.
So the next round, I removed the penguin and turtle to force a harder choice, so many in that age group switched to the next most familiar and cute creature: the clown fish.  As my fellow intern Nick puts it, they’re only interested in “charismatic mega fauna”.
However, there were many people who chose things that were more local and meaningful to them personally.  My favorite comment I found funny was, “I chose Dungeness Crab, because I like to eat them, and I’m interested in keeping that going.”
The two most surprising comments were from gentlemen who were roughly age 60 to 70.  This demographic is kind of stereotyped as being very skeptical of climate change, and I will admit that I pegged them as probably being in that group.  One chose phytoplankton and said, “they are basic foodstuff.  They’re at the bottom  of the food chain, so that has effects all the way up.”  The other chose algae and said, “some people don’t believe [climate change] and think it’s ‘business as usual’, but I don’t think so.  Algae will probably be one of the first affected.”  Wooohoo!  You go dudes!  Thanks for changing my perception.

This week I’m preparing for the next phase of evaluation in which I will get into more detail with visitors about the exhibit itself, how it will work, and what types of resources they would want available on it.  A graphic designer, Alison, who works on projects for the VC is making a graphic for me to print and show to visitors while I talk to them about the exhibit.  This will really help them to visualize what I’m talking about.

The psychology behind talking to people and getting their opinions is staggering.  Every question, phrase, graphic, etc. I use goes through this complex interview process in my brain.  I wonder things such as, “how might people misinterpret this?”  “Will using this picture bias people’s responses?”  “Will using this phrase turn people away and change their answers?”  “If I color code, what are these colors going to make people think?”
That last one is big right now, along with positioning of things.  I am going to ask people to self-categorize into one of the groups from “Global Warming’s Six Americas,” but the graphic I was going to use from that study has different colors for each and I wonder if people will choose their favorite color, or think that one color is better or more desirable or think that I as the researcher want to lean them a certain direction based on the color or position.  If I lay out the 6 options top to bottom, it makes the top seem to be best and the bottom worst.  Colors- are warm or cool colors more acceptable and which do I appear to be favoring?  If I lay them left to right it might feel best to worst on a spectrum, or perhaps even political left wing/ right wing.  When you are doing research with human beings, whose thought patterns are so complex, you really can NOT control for every variable and you just have to do your best and realize that the results are influenced by many things.”

Learning from each other: Visiting other museums as a professional

Posted on by | Leave a reply

As Susan posted, several of the students working with Shawn and on various projects related to the lab took a field trip to a couple of other local museums. It’s something a lot of us in the field seem to do (or at least, that’s my impression), as museums seem to vary so much from community to community, even when they’re all science centers or all art museums, etc. There’s always something innovative going on (usually to manage tight budgets), and it’s really valuable especially to get to talk to other professionals at their home sites. I’ve visited large-city museums that were traditionally curatorial re-vamp their spaces a few at a time and create entirely new full-time programming to work in the new century (the Science Museum of London and its attached Dana Centre), and small-town places with hands-on versions of history and science rolled into one (the Mid-America Science Museum in Hot Springs, Arkansas has a great crawl-through cave exhibit “Underground Arkansas” alongside a good deal of Smithsonian Institution offerings). Each time I go, I see a bit of the familiar and a bit of the unique and local flair.

For instance, at the Science Factory, we found that a staff of 10 (not all full-time) plus a handful of contractors put on 9 weeks of sold-out summer camps a year, serving about 300 kids, even though their overall annual visitation is only about 37,000. For comparison, Hatfield gets 150,000 visitors, not including school groups, each year, and I don’t think we put on that many weeks of camp! In addition, as the building is in Alton Baker park, literally in the shadow of the U of O football stadium, the museum closes on game days due to the sheer traffic tangle. However, they turn around and sell tailgating parking and throw in membership as part of the package, raising a good deal of revenue when they might otherwise be losing money. To top it all off, they manage to rotate their exhibition about 3 times a year.

The Jordan Schnitzer Art Museum had its own issues; since they’re located on the main campus, parking is always a snag. And prior to a recent renovation, the building was so imposing and so not-well-marked that people actually had to ask if they were allowed to enter (our Physical Dimensions of FCL online class explores entrance spaces as an assignment). Now they have thriving adult programs as well as a full complement of tour groups. They are of such a size that they are rotating exhibitry nearly constantly, based not only on special long-term touring shows but also on the needs of professors who may change out a few pieces for a class.

This last part led me to ask about their volunteers who lead tours and how they keep up with all the changes. Just like the volunteers at Hatfield, the JSMA volunteers (“experience interpreters” rather than docents) have to be prepared for anything, since they aren’t always aware even when they start a tour what they may encounter. But their volunteers also undergo extensive training, spending about 4 hours a month in training on top of volunteering up to 3 days a month. Not only do they get updates on content of exhibits, but they also spend a lot of time practicing interaction techniques, which I witnessed as Sharon led a group around before we sat down with her. She had a camp group of maybe six 8-year-olds and had stopped them in front of a piece. She asked the group, “Do you think the building here was built fast or slow?” When two of the group had different answers, she asked them to justify their answers. I moved on before I heard how well they complied, but she certainly had the attention and participation of most of the group (ok, one of them was over on a nearby cushioned bench making face-down “bench angels”). Sharon told us that this was a concerted effort made over the past several years to encourage interpreters to go beyond simply delivering information.

What other places have you visited, and how are they making things work in creative ways? The Museum 2.0 blog is a great example of organizational change over the past year at the Santa Cruz Museum of Art.

Preparing for a different type of tsunami

Posted on by | Leave a reply

Another of our interns, (actually, they are all Oregon Sea Grant Summer Scholars), Nick, lets us know what it’s like trying to prepare for the “visitor tsunami” that’s bound to occur when we get our third wave tank all set, based somewhat on the inundation he gets as an on-floor interpreter:

“Working as a docent for the front desk and touch pools has provided abundant opportunity to interact with the public and I seem to learn as much information as I provide. Visitors ask so many interesting questions and also ask about local marine events: how is the Sea Turtle doing that washed up on the shore, inquiries about the tsunami debris and recently the Brown Pelican crisis at the Yaquina Head seabird colony. Visitors also bring in some unusual items and ask for help identifying them; one man brought in an orca tooth that he had discovered eroding out of a cliff.

Among my favorite duties is acting as the guide for the daily tour of the Yaquina Bay estuary describing the marine plants and animals of the bay. Participants especially like discovering the tiny crabs that are often living under the very rocks they are standing on. It is pretty rewarding and members of the tour group have often told me that after taking the tour, they now want to become marine biologists.  I have also been helping with the Ocean Quest multimedia presentation in the auditorium. We have been working out the bugs in the presentation and it is finally at a point where we are happy with it.

Our main project involves working on three wave tank exhibits. Brian has been working with the wave energy exhibit, designing an experimental “wave power” device that looks like a futuristic mechanical snake. Diana has been working with the erosion tank and has had to be vigilant in order to prevent the “sandy beach” from becoming a mess from enthusiastic children. My project has been working with our tsunami tank. I have been working on designing ideal tsunami proof structures as well as showing buildings that will not be able to survive the wave. Using Legos as building materials, I have attempted to construct scale models of different building to see if the various designs are demolished or not with the wave tank.

The tsunami project has had some problems associated with it. For starters we have had endless computer glitches and malfunctions that often make it difficult just to run the machine. We have also been experimenting with different lengths of continental slope (represented by an acrylic ramp). Additionally, we found that Legos seem to stick together really, really well….sometimes so well that buildings that should be demolished are still left standing!  We have had to resort to sanding the individual bricks so that they do not stick together as well and will better represent actual building materials. We are hopeful that these problems will be fixed within a few weeks when we plan to open the tank to the public. The educational intent of the display is to challenge visitors to construct a building that can stand up to a tsunami wave. We are confident it has the makings of a fun and interesting exhibit and hope it will be very popular with our visitors!”

 

Duplicating Wave Energy Small-Scale

Posted on by | Leave a reply

Today our HMSC VC Intern Brian Verwey gives us an update on his work for the summer:

“This summer the Visitor Center is working on opening three new exhibits explaining three separate aspects of wave energy on the Oregon Coast.  Part of our internship for the summer is tackling these new displays and making them “public friendly.” Diana is working on erosion due to wave action along the beach.  Nick is creating tsunami proof structures.  I am designing wave energy converter (WEC) models. Tuesday is our project day at the Visitor Center so instead of working on the floor we spend most of the day in the new wave energy section of the VC (closed to the public for now).

The idea behind the WEC exhibit is to demonstrate how energy is created from waves.  To do this we are simplifying a working WEC design called a point absorber.  A point absorber works by moving a magnet through as coil of wire that then creates an electromagnetic current.  It’s a pretty basic concept that has proven very difficult to show in our wave tank in the VC.  The most challenging part of the exhibit so far is getting our version of the point absorber to create electricity that can be displayed on a computer monitor and in turn will be easily recognized and understood by the public. As of yet it isn’t easy to understand. So for now I’ve focused my efforts on creating other models of WECs that don’t actually create energy but give the public an idea of how they work [such as the one below].

 

 

Last Tuesday I worked on creating an attenuating wave energy device similar to the Scottish “Pelamis.” It’s about 36” long and fits perfectly in one of our wave tanks.  It works pretty well and for the next few project days I will be working out some kinks in the design. The main kink is creating an anchor system to attach it to the tanks so it doesn’t float away when waves are produced, and the other big kink is somehow orienting the model so when waves hit it, it doesn’t flip onto its side.”

Time vs. money

It’s time to buy more cameras, so Mark and I went to our observation booth and wrestled with what to buy. We had four variables: dome (zoomable) vs. brick (non-zoomable) and low-res (640×480) vs. high-res (but wide screen). He had four issues: 1) some places have no power access, so those angles required high-resolution brick cameras (what a strange feature of high-res camera to not require plug-in power!), 2) we had some “interaction” (i.e. close-up exhibit observations) that looked fine at low-res but others that looked bad, 3) lighting varies from area to area and sometimes within the camera view (this dynamic lighting is handled better with high-res), and 4) current position and/or view of the cameras wasn’t always as great as we’d first thought. This, we thought, was a pretty sticky and annoying problem that we needed to solve to make our next purchase.

Mark was planning to buy 12 cameras, and wanted to know what mix of brick/dome and high/low-res we needed, keeping in mind the high-res cameras are about $200 more each. We kept looking at many of the 25 current views and each seemed to have a different issue or, really, combination of the four. So we went back and forth on a bunch of the current cameras, trying to decide which ones were fine, which ones needed high-res, and which we could get away with low-res. After about 10 minutes and no real concrete progress, I wanted a list of the cameras we weren’t satisfied with and then what we wanted to replace each, including ones that were high-res when they didn’t need to be (meaning that we could repurpose a high-res elsewhere). Suddenly, it dawned on me that this was a) not going to be our final purchase, b) still likely just a guess until things were re-installed and additionally installed and lived with. So I asked why we didn’t just get 12 high-res, and if we didn’t like them in the spots we replaced and were still unsatisfied with whatever we repurposed after the high-res, we could move them again, even to the remaining exhibit areas that we haven’t begun to cover yet. Then we can purchase the cheaper low-res cameras later and save the money at the end of the grant, but have plenty of high-res for where we need it. I just realized we were sitting around arguing over a couple thousand dollars that we would probably end up spending anyway to purchase high-res cameras later, so we didn’t have to worry about it right at this minute. It ended up being a pretty easy decision.
