Go ahead. Take your toddler to the museum!

by Victoria Smith

When my children were younger, and I was hip to the toddler scene, I would schedule play dates at all the usual places: I’d push the stroller to the park, load up the red wagon for the zoo, and slip Cheerios to fussy babies during story time at the library. The Houston Museum of Natural Science was also on the top of my list, and I was surprised other moms thought their kids were too young to appreciate it.


“Oh, no! He’s after us!”

The museum is fantastic for small kids! It’s got air conditioning, wide spaces to navigate, and if you have a two-year old who will only eat peanut butter sandwiches cut in squares, not triangles, you are welcome to bring your own food.

And of course, DINOSAURS! They’re huge, they’re exciting and they have pointy teeth (at least the carnivores do). Even if you don’t have a toddler who can identify every prehistoric creature and pronounce the names better than most college graduates, every kid loves dinosaurs. (Thank you, Dr. Scott the Paleontologist!) In the Morian Hall of Paleontology, the dinosaurs are mounted in active poses, bringing these ancient creatures to life for young visitors. The displays tell a story, and the murals illustrate it.


It’s the Circle of Life, baby.

Speaking of stories, my youngest daughter’s favorite story is the lion chasing the zebra in the Hall of African Wildlife.  Even though she knows how it’s going to end for that poor zebra, every time she asks, “Mommy, tell me the story of the lion and the zebra.” It’s not only a great chance throw in a few Mufasa quotes, but it’s also great to discuss how nature doesn’t waste anything because after the predators come the scavengers. I usually manage to work in a moral lesson about the selfish leopard who won’t share, too. There are interdisciplinary opportunities at every turn!


Let me know when the wonderment is over, so Momma can sit down!

The Cockrell Butterfly Center is one of our favorite spots to visit, and perhaps even my favorite place in the museum, period. Yes, the awe and delight in a young child’s face is a daily miracle, but they’ve got cushioned benches and free wi-fi! When you’re through with the center, there’s a beehive-themed play area with puzzles and blocks, and most importantly, it’s enclosed!


My daughter at age four, as an assistant in a chemistry demonstration…

If you want your daughters (and sons, of course) to grow up to interested in science, it’s never too early to start. Let them know that science is fun and not scary. The museum has dedicated tour guides who specialize in making the exhibits come alive for young children, and docents who offer many hands-on experiences. Kids can touch real fossils, feel if minerals are rough or smooth, and guess if an animal was an herbivore or carnivore while holding an actual tooth! It’s all there, at their eye-level.  


…and at age eight, taking on a brain dissection at Xplorations summer camp.

So now that the big kids are back in school, it’s a great time to plan a visit to the museum. If you’re lucky like me, you can convince their grandparents that even though your one-year-old can’t talk, he really wants a membership for his birthday, and not another toy to clutter the playroom.

Chemistry Demonstrations: This Eureka Moment is brought to you by HMNS Volunteers

Editor’s note: Today’s post was written by Tom Szlucha, a volunteer docent here at the Museum.

“EUREKA!” In his excitement, Archimedes runs down the street, naked and dripping wet from his bath. In this legend, he makes a discovery as he immerses himself in the bathtub and notices the water rise. 

It is this observation that leads to the solution to a problem that had been bothering him for some time.The king needs to know if the crown recently delivered by the goldsmith is pure gold or some cheap alloy — and Archimedes has found a way to determine what the crown’s made of!

This example of scientific discovery is based on the very simple observation of the water being displaced as a mass is lowered into it. Archimedes is obviously very excited by his discovery (maybe a bit too excited).

The ConocoPhillips “Hands-On” Demonstration Lab in the new Welch Hall of Chemistry stimulates this same sense of scientific discovery in visitors to HMNS (no bathtub for us though). Chemistry docents conduct hands-on experiments in this lab — experiments that teach, inspire and, most of all, are fun.


Now, back to Archimedes…According to the legend, he has to determine if the density of the metal in the crown is pure gold or a cheap alloy of gold.

He develops a very simple experiment to see if a density difference exists between the crown and gold. He places the crown on one side of a balance beam. On the opposite side, he places gold until the scale is balanced.

Then, he lowers the apparatus into a tub of water. If the balance tips to one side because the materials exhibit different buoyancy, then there is a difference in density — which would mean that a gold alloy was used to make the crown.

The principles of density and buoyancy involved in the Archimedes experiment are included in many of our chemistry demonstrations. The demonstrations are given by a group of dedicated HMNS chemistry docents. They come from a variety of backgrounds: chemists, engineers, educators, college students, and others. They have the enjoyment of making these fun, simple, and safe demonstrations that teach and instill an interest in physical science. In return, they are rewarded for their time and effort by seeing children smile with excitement as they make their own “Eureka!” discoveries.

Tom Szlucha using the “pass-through” to set up

The theater area for these demonstrations is new and improved, a literal “step up” from the work cart that used to be parked in the old Chemistry Hall on the first floor. Downstairs, the new theater has a raised stage with large worktables in front and behind the presenter, allowing for multiple experimental setups. There are pass-through cabinets behind the rear table that facilitate the movement of materials from the preparation and a storage room located behind the stage.

The audience is seated on rows of black, rubber-coated cubes under the illumination of air molecules hanging from the ceiling. These molecules are different colors, proportionally representing the mixture of nitrogen, oxygen, and trace gases in the Earth’s atmosphere. The suspended molecules make a perfect transition into experiments associated with gases. The demonstration area is enhanced with a well-tuned wireless sound system, making the presenter easily heard by the seated audience.

There are a variety of experiments performed here, most using simple household materials. Almost every school kid knows how to make a “volcanic eruption” by mixing baking soda with vinegar. But did you know that this acid/base reaction is endothermic, meaning that it absorbs energy, thus creating a cooling effect? A product of this chemical reaction is carbon dioxide gas. Since carbon dioxide is denser (i.e., heavier) than air, it can be poured to extinguish a flame. This stunt can come off as a magic trick—there is no liquid involved as you pour the invisible gas and extinguish the candle flame. Other practical lessons are taught through simple experiments, answering questions such as why do we wash our hands with soap; how do scientists measure the strength of acids and bases; and what does a baby diaper have in common with Jell-O?

Chemistry docents have plenty of opportunities to interact with the audience by soliciting help with these experiments. Participants learn about material density when they make hard-boiled eggs float on salt water and sink in plain water. They help show that Diet Coke is less dense than regular Coke. But why? The explanation is somewhat shocking. The average twelve-ounce can of sugar-sweetened soda contains about forty grams of refined sugar. That’s about three heaping tablespoons of sugar!

Participants also make a rubber “Superball” out of white glue and a simple ingredient found in the laundry isle of the grocery store. This polymerization process utilizes the boron atom in Twenty Mule Team Borax to cross-link the chains of polymers found in casein-based white glue. This experiment helps to teach visitors about some of the characteristics of polymers.

Audiences entertained at the ConocoPhillips Hands-On Chemistry Demonstration Lab range from large school groups to families and individuals spending the day at the museum. The demonstrator has to be somewhat flexible, modifying their routine for the audience that is present. Having multiple tables with large surfaces allows for a number of different experiments to be set up and ready to go. Some experiments may be more suited to a particular age group, so the presenter can pick and choose, thus customizing each show to the specific audience.
