Late Night with Catalysts: New program offers after-hours fun for the young at heart

When I tell people I’m the Overnight Coordinator at the Houston Museum of Natural Science, I usually get one of two reactions. It’s either a sarcastic “Oh, does everything come to life at night?” or an astounded “People can spend the night there?!” While I’m in the Youth Education Programs department and typically work with the kiddos, we decided to partner with the Catalysts young professionals group at HMNS to create a late-night event for the young at heart. On July 30 we had our first-ever adult late night at HMNS exclusively for the Catalysts group.

Since it’s summertime, we decided to take everyone on a trip down memory lane to good ol’ summer camp. Of course, we had to make it a trip with a bit of that HMNS pizzazz. Late-nighters could “roast” s’mores in our toaster ovens as an indoor (and flameless) spin on everyone’s favorite campfire cuisine. We had a make-your-own trail mix bar complete with barbecue flavored mealworms as an optional but delicious addition. We also had some Cool Chemistry demonstrations by seasoned Outreach presenter Sahil Patel and flashlight-led tours of the Morian Hall of Paleontology with Connor Eichenwald from the museum’s W.T. & Louise J. Moran Ecoteen Program. Finally, if campers wanted to capture the moment, we had Smilebooth there with a bevy of youth ed-crafted, camp-themed props! See some of our favorite snapshots below.

If a summer camp-themed late-night sounds like your idea of a night well spent, then Catalysts is the group for you! Our young professionals group gives you access to a variety of events throughout the year including tickets to an exclusive Catalysts events each quarter and tickets to our Mixers and Elixirs events during the summer. That’s on top of the usual membership benefits like free access to our renowned permanent exhibition halls and advance notice of upcoming events and special exhibitions.

Sam Lam: Legacy Camper

Once in a while, the Houston Museum of Natural Science Xplorations program gives children so much enthusiasm about science that they never really leave the museum. Sam Lam discovered the museum as a child with the Xplorations program, and has since never missed a summer at the museum. She now teaches some of the same summer camps she enjoyed when she was a kid.

HMNS: When did you start attending summer camp here? And why?

SL: I started attending camps at HMNS when I was 6 or 7 years old, around 1998. My mom worked downtown and decided to look into sending us to camp at HMNS. After just one week, I was hooked. From that point on, I kept pestering her to sign me up for Xplorations year after year. 

3

HMNS: What was your favorite class? What made it your favorite? Any stories from that class?

SL: My favorite class was Wizard Science Academy. Reading Harry Potter was a big part of my childhood, so it was very exciting to be able to attend a summer camp that incorporated science with a Hogwarts twist! I still remember dissecting an owl pellet and being convinced it was from Hedwig. I remember having Nicole Temple as my teacher and being so excited that she secretly let me switch out of the house that the Sorting Hat chose for me into the house of my choice.

HMNS: What is your favorite memory from summer camp?

SL: I took a camp called, “Thrills, Chills, and Disasters” that talked all about physics and the science behind amusement parks. As an end-of-the-week field trip that wrapped up all our learning, we were able to go to Astroworld to see the physics in action. I loved going around and riding rides with all of my camp friends. It was such a unique opportunity that I am lucky to have had!

HMNS: If you could go back to Xplorations Summer Camp for one week this summer, what class would you take and why?

SL: I would definitely sign up for Bedazzled! I have had the best time teaching that camp for the past few years. I think the best part of Bedazzled is the Spa Day on Friday when campers get to dress as comfortable as they’d like and pamper themselves for the day. A day with magnetic nail polish and a nice, relaxing mud mask? Sign me up!

HMNS: What made you decide to come back and work at HMNS?

SL: When I was a camper, the Xplorations staff was always so enthusiastic and fun to be around. Because of them, I never wanted to leave camp when my mom came to pick me up. I wanted to keep the fun going and stay with them. When I officially “aged-out” of camp, I knew I wanted to come back and make camp a positive experience for others, just like the staff did for me.

HMNS: How did the Xplorations Summer Camp influence your life?

SL: During the summers, HMNS has been my second home for as long as I can remember and the people I have met there have become like another family to me. Some of the best friendships I have are with people I have met through Xplorations. Thanks to Xplorations and its amazing staff, I was able to meet and teach with fantastic teachers who inspired me to become a teacher myself. The best part of Xplorations Summer Camp is the people you meet—from the awesome campers, to the fun-loving TA’s and teachers, and the always cheerful and helpful education staff. My best memories from camp are because of them.

Sahil Patel: Legacy Camper

Once in a while, the Houston Museum of Natural Science Xplorations program gives children so much enthusiasm about science that they never really leave the museum. Sahil Patel discovered the museum as a child with the Xplorations program, and moved on to become an Ecoteen as he grew older. Now, he is an HMNS Outreach Presenter and a writer for the BEYONDbones blog.

Patel teaches a children’s class about the density of various items for the Science Start Outreach Program. Interested in the Houston Museum of Natural Science since age 6, Patel hopes to share his excitement with other kids, cultivating their education through HMNS.

HMNS: When did you start attending summer camp here? And why?

SP: I started attending camp when I was six years old. I didn’t start going to school until Kindergarten, but I would go to work with my mom every day. Every day at lunch time, we would go to either the zoo or the museum, depending on weather, and I was hooked. The real reason I came to camp is probably so my mom could get me out of her office, but I kept coming back because I just never had a bad time. There wasn’t a single class I didn’t enjoy.

HMNS: What was your favorite class? What made it your favorite? Any stories from that class?

SP: Every summer, I had to take the Space Commander class; I must have taken it at least four times. My favorite part was the Expedition Center mission to Mars or the Moon on Friday afternoon. I loved it so much that I had a birthday party mission one year! Every time, I tried to be on a different team inside and was mostly successful. My favorite of those had to be the CIMCOM team, which got to talk to mission control. Years later, when I was a Moran Ecoteen, I got to be a part of mission control for a summer camp mission and loved every second of that, too!

Sahil Ecoteen 2

As an Ecoteen in 2010, Patel interned with Paleontology Curator David Temple.

HMNS: What is your favorite memory from summer camp?

SP: I enjoyed the camps that used to take field trips; one of my favorites was called Thrills and Chills, and the physics-based camp ended with a trip to Astroworld on Friday! Sadly, neither Thrills and Chills nor Astroworld still exist. I also enjoyed the Senior Coastal Ecology class that would take daytrips to Galveston to study wildlife and various aspects of the gulf coast, but this camp was discontinued in the late 2000’s. But I’d say my favorite memory was from when I took Crime Scene Investigators one year. Friday afternoon of Crime Scene Investigators involves a crime scene that the Xplorations staff and Moran Ecoteens set up, and our class went about examining evidence and following clues to try and figure out who committed the crime. Low and behold, it was our TA, who took off out the door and down the hall before he was captured and brought back to the classroom to explain himself.

HMNS: If you could go back to Xplorations Summer Camp for one week this summer, what class would you take and why?

SP: I’ve taken quite a few of the camps that are still offered today, but one that I didn’t get to that I always wanted to take was Wizard Science Academy. Harry Potter and the Sorcerer’s Stone was released on my tenth birthday, and I was obsessed from the opening chorus. The Potter-themed summer camps weren’t created until I was too old to go to camp, and I always felt like I missed out on something amazing. That was confirmed for me when my brother took Wizard Science Academy four years ago and came home with a wand, a broomstick, and a Triwizard Tournament championship.

Sahil Ecoteen 1

As an Ecoteen, Patel was present for the blooming of Lois the Corpse Flower in 2010.

HMNS: What made you decide to come back and work at HMNS?

SP: I guess you could say that I never left. Since I started summer camp at age 6, the only summer I did not work at the museum was when I was 14, because I thought I was ineligible for the Moran Ecoteen Program at that age. HMNS has always held a special place in my heart, from the moment I saw the massive T. rex in the old Glassell Hall. The museum has always made me question what I know, motivated me to learn further, and inspired me to pursue a career in science. Over the years, I fell in love with this place as I learned more and more about it. I got to a point where a summer without HMNS was a summer wasted. I wanted to show others why I was so passionate about this place and what made HMNS so special to me. Coming to work here was a no-brainer.

With HMNS Outreach, Patel teaches children TEKS-based science skills with the Chevron Earth Science on Wheels: Dinosaur Discovery program.

HMNS: How did the Xplorations Summer Camp influence your life?

SP: Xplorations Summer Camp has had nothing but a positive impact on my life and thousands of others. The museum set me up for success by instilling in me a love of learning at a young age; Xplorations made science fun! With a summer’s worth of learning at camp, I was ready to go when school started up again in August, and I had all kinds of new, useful knowledge to impress my classmates. But most importantly, the summers I spent at Xplorations opened a door for me to a true passion: teaching. Xplorations led me to a career at HMNS. I wouldn’t be here today without it.

Even hard at work at his desk in the outreach office, scheduling educational programs, Patel has a good time. He can’t imagine working anywhere else.

 

Ice cream science: Make a cool treat to beat the summer heat

It’s getting to that time of year when it’s so hot and yucky outside that everything cold is better.

It’s also a time for telling kids about how, when you were their age, if you wanted ice cream you had to turn a crank until your arms fell off (presumably while walking uphill to school both ways and fighting off bears…).

7

Here in the Houston Museum of Natural Science education department, we have tried making ice cream in a variety of ways to see what is easiest for kids, and not all ways are equal. (Pro tip: Those special ice cream-making balls they sell for kids freeze shut, and then kids are sad. Not recommended.) Our favorite way, at the end of this post, is fairly cheap and easy and fun for kids, but before we get to the instructions, let’s talk about some science.

To make ice cream, you will of course need ice. The ice is simply to lower the temperature of the cream to the freezing point, but if you just used ice alone and let it sit, you’d end up with a solid block of cream – more like an ice cube – and it would take longer to freeze. What makes ice cream special is salt and stirring.

6

Water freezes at 32° F, but sprinkling salt on the ice lowers the freezing/melting point of water. How, you say? In order for liquid water to freeze to solid ice, all of the water molecules have to slow down enough to connect to each other and form solid crystals. When this happens, the water loses kinetic energy due to the decrease in movement of those molecules. Because temperature is a measurement of kinetic energy, this results in a lower temperature.

The presence of salt interferes with this process. The water molecules can’t attract each other as easily because they are also attracted to the sodium and chloride ions from the salt. Mixing the salt, ice, and water together results in a temperature below the freezing point of water, which helps the cream freeze faster. The shaking or stirring helps cool the cream evenly and efficiently. In ice cream, this lower freezing point turns the fats into solids, but the water content to be almost frozen.

8

What about the milk, then? It is much easier to make ice cream with creamer, heavy whipping cream, or half-and-half than to use skim milk because of the higher fat content in cream. You can make ice cream with skim milk, but it is really, really, really hard to do by hand, AND you have already committed to making ice cream, so I feel like you have acknowledged the inherent risk of fat consumption that comes with making a frozen confectionery delight. Just use the full-fat stuff, and let’s all move on.

What does the fat do, anyway? Primarily the higher fat content allows for a richer, creamier texture and a more delicious flavor in your finished product. The reason for this is that when you are cooling and mixing the cream, you are also introducing air molecules to the liquid. The bits of fat in the cream add a little structure to the ice cream and trap these air molecules in the solution as it forms. This, plus the lower freezing temperature, enables you to be able to scoop the ice cream fairly easily because it allows for there to be a bit of unfrozen water in the ice cream, which stops the ice cream from becoming a solid block of ice.

5

If you have ever had ice cream that has grown ice crystals and gotten a bit of freezer burn, those ice crystals appeared because the unfrozen water in the ice cream had a chance to migrate a little bit when the ice cream was warmed slightly on the ride home or when it was left on a counter a little too long and then frozen again. There are things called stabilizers added to your ice cream to prevent this from happening. Most ice creams today have one of five stabilizers added to them: carob bean gum* (a type of bean from Africa), carrageenan (a type of algae), guar gum (a type of legume from India), sodium alginate (made from seaweed) or carboxymethyl cellulose (sounds scary but it’s plant-based). Often, if you read the label, you will see more than one of these in your ice cream to keep it smooth and delicious.

9

* Carob beans, or locust beans, are cool. They are from exotic African trees and each bean is so similar that at one point they were used as a unit of measurement for gold and silver. We still use this measurement today, but the name has changed over time to Karat.

So now that you have had a little lecture about the science of ice cream, let’s get to the delicious lab work.

 

Activity: ICE CREAM!!!!

Materials:

Individual serving containers of coffee creamer

Ice

Small waterproof container or quality sealable plastic sack big enough for about two or three cups of chipped ice

Salt, any variety

A dish towel to insulate your hands

Optional: Inexhaustible energy of small child-based labor

Procedure:

  1. Find some liquid coffee creamers in individual pots.
  2. Put ice in your water proof container, filling it about a third of the way. Smaller chunks of ice work better because there is more surface area, but any ice will do.
  3. Layer your salt on your ice. Several solid sprinkles will do, but if you are nervous about the quantity, add some extra just in case. It won’t hurt anything.
  4. Put your sealed creamer cup(s) in your container and then put more ice in, filling it about 2/3 of the way.
  5. Layer on more salt.
  6. Finish filling the container with ice.
  7. Start shaking your container. Make sure it is well sealed and that you have a firm grip on it. No one wants to be injured in an ice cream-related accident. There is no way to spin that so it sounds cool. Also, this is an excellent job for kids to help with. Put on a nice, long song or two and let them wiggle till they drop. About ten minutes will do it, but you will know when you are getting close because a frost will form on the outside of your container. If you don’t feel frost forming after a couple of minutes, add more salt. To speed this process up, start with creamer pods that have been stored in the fridge. This way, your creamer will start at about 50° F, and you won’t have to work so hard.
  8. After about 10 minutes of shake, shake, shaking your ice cream, dig your creamer cup out of the ice and wipe it off.
  9. Ta dah! You are done. Unless you want to make this tablespoon of delicious homemade ice cream into a sundae and add chocolate and banana or some jelly for more flavor.

Note: If you are thinking to yourself, “That seems like a lot of work for a tablespoon of ice cream,” well… it is. But it’s also science. So there.

If you get the liquid creamer that comes in a larger container at the grocery store, you can increase the volume of your creamer and make MORE ice cream. If you choose to do this, you will need to find a small waterproof (and I would suggest plastic) container to pour the creamer into and then a slightly larger waterproof container for all the ice and the salt. It’s the same procedure, just with a larger amount of the ingredients!
