Kids Explore STEAM Careers with HMNS Outreach

Inspiring a child takes effort, time, passion and heart. It’s why we do what we do.

At the Houston Museum of Natural Science, discoveries are made daily. The sounds of learning fill our hallways every day, from the gasp of wonder from a kid stepping onto the Morian Overlook for the first time or the squeal of delight as a butterfly in the Cockrell Butterfly Center rests on a child’s shoulder. Those sounds are all the evidence we need to know we are upholding HMNS’ mission, its commitment to education.

For the kids that may not be able to get to the museum, there is HMNS Outreach. Our variety of programs brings HMNS straight to the community, visiting hundreds of schools and organizations each year and reaching more than 100,000 children in 2015 alone. The ultimate goal is to instill in these kids a love of learning that will carry them to new heights in their careers and throughout their lives.

Here are some of the many STEAM careers that HMNS Outreach can inspire a child to reach for.

Veterinarian

The TOTAL Wildlife On Wheels offers an extraordinary look at animals of all kinds. Students get an up close and personal encounter with wildlife ranging from snakes and frogs to birds and mammals.

Forensic Scientist

A presentation of Cleanup Crew from the Bugs On Wheels program will cover the process of decomposition and the return of vital elements to the Earth. These principles of decomposition are crucial to forensic scientists, who use arthropods and fungi to study crime scenes and gather more information.

Physician

Body Works is our newest set of programs in the Science Start family, and these presentations focus on the anatomy and capabilities of the human body. From the brain to the heart to the skeleton, each of these presentations will provide students with a comprehensive overview of what we can do with what we’ve got.

Geologist

A Chevron Earth Science On Wheels program like Know Your Rocks is immensely useful for future careers in Geology. A students’ knowledge of the rock cycle and the differences between different types of rocks and fuels can be vital in fields such as the energy industry.

Astronomer

A visit from the HMNS Discovery Dome includes more than 40 different shows about a range of topics, including a classic planetarium show, The Starry Night. One of today’s kids could discover a new planet, a galaxy, or even a black hole, and the Dome provides a great foundation for an interest in astronomy.

Students at Reagan High School file into the Discovery Dome for a screening of Cosmic Collisions, a show narrated by Robert Redford about different outer space encounters between celestial objects.

Anthropologist

An interest in foreign cultures can take you all over the world or even back in time. Anthropologists study the history of humanity, and Docents To Go programs such as Native Americans or Ancient Egypt provide students with an introduction to different communities and societies.

Ready, set, STEM! 2016 HMNS Outreach programs focus on physical fitness!

Get yourself in gear this summer with the Houston Museum of Natural Science and our Science Start Outreach programs! It’s never too early to register for these super fun educational activities.

Take the first steps to physical fitness by understanding how the human body works and how it compares to other animals with our brand new Body Works programs! There will be three different programs, each focusing on a different portion of the body: Movin’ and Shakin’, Pump It Up and Head Honcho.

Sahil1

How do the different parts of your body work in coordination to throw a football? We’ll discuss human anatomy in Science Start: Body Works!

Any discussion of sports and fitness needs to include a lengthy section on the human body’s skeleton and muscles, and we’ll tackle those topics in Movin’ and Shakin’! The components of our endoskeleton give our body its shape and stability; it would be pretty tough to shoot some hoops without bones! The muscles, tendons and ligaments allow for efficient and calculated motion that lets humans do everything from riding a bike to kicking a ball.

We’ll explore differences between our arms and the appendages of other animals that have different purposes, like a bird’s wing or a whale’s flipper. We’ll discover how our muscles work together to make simple actions like smiling possible. And we’ll do it all with museum specimens and a museum educator leading the way!

Next, it’s important to understand how the body gets the energy it needs to keep going. Pump It Up takes a look at the heart, blood and kidneys and how they work together to keep the body running smoothly. The bloodstream is vital for exercise, as our red blood cells carry oxygen and nutrients throughout the body, supplying cells in muscles with important resources to continue working properly. Of course, the blood won’t get very far without the pumping action of the heart, and the bloodstream would not be as effective without the filtering power of the kidneys.

blood-1237550

In Pump It Up, we’ll compare the human heart with that of an animal much smaller than us (a rat) and an animal much larger (a cow). We will take a look at the rainbow of different colors of blood represented by various animals around the world as well as how human kidneys keep our blood pure. We’ll certainly get your heart racing!

Of course, to complete an action as complex as throwing a curveball, there has to be a manager, coordinating all of the motions to produce a consistent result. That’s the head honcho, so to speak, or the brain! The human brain has around 100 billion neurons, and many of those have hundreds of synapses (essentially connections between neurons). It’s estimated that there are over 100 trillion synapses in the human brain!

Sahil2

In Head Honcho, we’ll compare our brain with animals of all kinds, from the ancient Tyrannosaurus rex to modern sharks. From there, we’ll look at the skulls and teeth of other animals and how we can figure out what that animal ate from what its teeth look like.

Each of these programs correlates to TEKS objectives and is perfect for young learners! Book now for these awesome programs, beginning June 1.

Sports Science: Pitching!

We, as a nation, love applied physics. If anything, that’s all that sports are.

With the Houston Astros on the brink of advancing further in the 2015 Major League Baseball playoffs, take a look at this physics-based pitching preview of tonight’s American League Divisional Series Game 5 matchup between the Astros and the Kansas City Royals.

My baseball coach growing up was my friend’s dad, named Paul Mancillas. He loved to say that hitting was timing and that pitching was about disrupting that timing. He could not have been more correct. Baseball is a sport in which a fraction of a second can mean the difference between hitting a home run and swinging and missing a pitch.

The announced starter for the Astros is Collin McHugh, who was the winning pitcher in 19 games during the regular season as well as in Game 1 of this series in Kansas City. He relies on four types of pitches: a four-seam fastball, a curveball, a cutter, and a changeup.

pitch3

The grip for a four-seam fastball sets two fingers across the stitching, held horizontally. The grip launches the ball into a backspin, causing greater acceleration through the air. Photo by: Jason Schaefer.

McHugh throws his fastball at approximately 90 miles per hour. This means that the ball will travel the 60 feet, 6 inches from the pitcher’s mound to home plate in approximately 458 milliseconds! Astros hitters will have even less time to react; the Royals’ expected starter Johnny Cueto throws his fastball at around 93 mph, so it will reach home plate in about 444 milliseconds!

AdairSwing (1)

An average MLB player can locate the moving baseball in about 140 milliseconds and swing his bat in approximately 150 milliseconds. So subtracting that away from the previous numbers, the batter has about 150 milliseconds to make the decision to swing or not swing at the pitch. Take too long to make the decision, and you swing too late and miss the pitch or foul it away to the opposite side.

But if a pitcher only throws fastballs at the same speed, he becomes too predictable, and a batter can easily time his swing to make good contact. That’s where the other pitches come in.

pitch1

A wider, more even grip across the stitching makes a changeup move more slowly. Photo by: Jason Schaefer.

A changeup is a pitch that looks like a fastball while moving but arrives at the plate much more slowly. McHugh and Cueto each throw a changeup at around 83 mph, which travels to home plate in approximately 497 milliseconds. A batter expecting a fastball would start his swing 50 milliseconds early and, instead of hitting the ball with the fattest part of the bat, miss the pitch completely.

pitch2

For a cutter or cut fastball, a slightly off-center grip causes the ball to curve right just before crossing the plate. Photo by: Jason Schaefer.

In addition to changes in speed, some pitchers rely on pitches that move horizontally or vertically. McHugh throws a cutter, or cut fastball, which has the speed of a fastball but moves horizontally right before it reaches home plate. A pitcher would hold the ball similarly to a fastball, but with a slightly off-center grip. Since a batter’s timing won’t be disrupted by a change in speed, this pitch is designed to create weaker contact with the ball. The barrel of the bat would be in one place while the ball would be in another, usually resulting in an easy-to-field ground ball.

pitch5

A curveball relies on a different grip and throwing technique to achieve changes in both movement and speed. Photo by: Jason Schaefer.

Combine movement with change in speed to get the deadly curveball. A great curveball has what’s called 12-to-6 motion, meaning that it dips straight down as if going from the 12:00 position on a clock to 6:00. This occurs because of the spin of the ball. The rotation of the ball causes the air around it to rotate as well. As the air is ejected on the upper side of the ball, the ball itself moves in the opposite direction, downwards. This is Sir Isaac Newton’s Third Law of Motion in action!

pitch6

Proper curveball pitching technique calls for a sideways release of the ball. Photo by: Jason Schaefer.

In addition, many pitchers throw a curveball at least 10 mph slower than their fastball; McHugh actually throws his at around 74 mph, which reaches home plate in about 557 milliseconds, about 100 milliseconds slower than his fastball! The combination of reduced speed and change in direction makes hitting a curveball challenging for batters of all kinds.

The most important feature of the baseball to pitchers are the seams, those red stitches that hold the ball together. The stitches themselves create a disturbance in the air molecules around the ball, resulting in a clean pocket for the baseball to travel through with less resistance. This allows the ball to reach greater speeds.

Want to see if you can hit a major league fastball? All you need is a ruler and a friend! Have your friend hold the ruler in the air, and position your finger and thumb around the 0 centimeter mark. Tell your friend to drop the ruler at some point without telling you when, and try to catch the ruler between your fingers. Note the position of your fingers on the ruler; if you caught the ruler in 11 centimeters or less, you have a reaction time of about 149.8 milliseconds, which would be just fast enough to hit a 90 mph pitch! Now you just have to work on swinging the bat in 150 milliseconds, too, and maybe you could be the next big thing on the 2016 Houston Astros!

Let’s go ‘stros!

Animal Espionage: Meet the Spies, Traitors and Saboteurs of the Wild

This week, you’ll have the first chance to experience our new special exhibit, Spies, Traitors, and Saboteurs: Fear and Freedom in America – examining nine major periods in U.S. history when America faced threats from enemies within our borders. But did you know HMNS already features a few “sneaks” of our own? They’re just of the animal variety!

In our HMNS Outreach Programs, we highlight several examples of crafty creatures who have adapted creatively to their environments to prolong survival. Want to meet a few of these smart cookies? Come to our free Shell Educators’ Preview Sept. 29!

How do you become a spy? First, blend in!

Our first spy is a familiar animal to the Gulf Coast – the American alligator! One of the alligator’s strongest adaptations is its amazing camouflage. I remember fishing as a kid on the Sabine River and my dad pointing out a gator in the distance. I tried and tried, but I just couldn’t spot it! Only as we neared could I see the bumpy “dead log” silently watching us float by. Alligators are extremely well-adapted to ambush. With nostrils that stick out of the water like a snorkel and a clear inner eyelid to protect their eyes while they swim, their whole body can stay submerged as they await their prey. While too dangerous to approach in their natural habitat, our Wildlife On Wheels program Texas Wildlife often includes one of our baby alligators, still small enough to keep safely!

Several of our other spies star in our Bugs On Wheels: Amazing Arthropods program and are masters of disguise. The giant long-legged katydid, for example, is the world’s largest katydid, native to Malaysia. These awesome insects mimic leaves, and during the daylight hours they can safely remain motionless, cloaked in foliage, waiting to become active at night. They don’t only come in green though; these insects can have an endless array of shades and patterns to match the leaves of their unique habitats. And like many things that get better with age, so does their camouflage, as their back edge grows brown and tattered like an old leaf.

Traitors mean false friends.

In the natural world, traitors come in many guises, even that of seemingly innocuous plants! The pitcher plant, masquerading as a source of tasty nectar, lures in insects (sometimes even rodents) and traps them. Their victims cannot escape the waxy walls and sticky fluid inside. As their prey drowns, digestive enzymes help break down the body, allowing the plant to absorb the released nitrogen. You can meet three species of this unusual carnivore in our Cockrell Butterfly Center!

2

Another unique traitor native to our state is the Texas tortoise, often seen in our Wildlife On Wheels programs, though a threatened species in the state of Texas. Deceptively fierce, this desert dweller is extremely territorial, and males will fight to the death if a fellow tortoise challenges. Competitors rise up on front legs to charge, using the pronged gular scutes protruding from the shell to hook under the trespasser, attempting to flip him over. This is a deadly situation for a tortoise as all of the animal’s internal organs press down on the lungs, which causes him to suffocate if he cannot turn back over. Yikes!

The Science of Sabotage

1

Crushing prey with an estimated force of 60,000 Newtons, the bite of Tyrannosaurus rex would be lethal enough as it is, but some paleontologists, such as Farlow and Abler, debate that a more insidious biological superweapon could be concealed in those fearsome teeth. Fine serrations in each tooth provided strength and cutting power, but may have also allowed meat from T. rex’s last meal to linger, lending a perfect source for bacteria to feed on. Similar to that of a Komodo dragon, it is theorized that the bite of T. rex could deposit overwhelming amounts of bacteria, causing the wound to fester and become septic. Want to touch a T. rex tooth and feel the serrations? (We promise, ours are clean.) A visit from Dinosaur Discovery, part of Chevron Earth Science On Wheels, makes it possible!

OLYMPUS DIGITAL CAMERA

Our last saboteur certainly employs a most unusual method of dispatching enemies —how about getting licked to death! The lightning whelk, a carnivorous snail, uses the sharp edge of its shell to pry apart bivalves. Once open, the whelk uses its radula (think scratchy cat tongue, but much worse!) to lick and scrape the hapless victim into smaller pieces for consumption. Fun fact: this ruthless snail is the state shell of Texas, and can often be found on gulf coast beaches. Look for a “left-handed” (sinistral) shell, shaped so it’s easier to put your left hand in. Another great place to see a whelk? In our Wildlife On Wheels: Invertebrates program, or in the Strake Hall of Malacology!
