Come meet our Zebrafish team! They’ll greet visitors entering the BioLab from their special tank system. These Zebrafish help scientists understand developments, genetics, and human health through experimentation as the tank system allows the fish to be bred. Come see for yourself--are they spawning or seeking food? You can also check out their brain activity that is displayed above in a video using microscopy and genetic technology!
Water may look clear, but there are actually billions of tiny organisms living in lakes, creeks, and other bodies of water! Explore the plethora of microscopic life contained within small samples we have collected from various areas, including our own Town Creek behind the Science Mill. There are entire water worlds in every sample with wonders waiting to be discovered!
We spend so much time looking at our cell phones, why not be a scientist while doing so? Line up your phone’s camera with the microscopic lens built into the plexiglass to examine an array of items on different slides. Experiment with focusing the image on your screen, either by adjusting the glass or tapping your phone. Digitally explore the wonders of microscopic worlds, all in the palm of your hand. Snap a photo and share with friends! #sciencemill
Super Microbe Power
Bacteria may be tiny, but they are just as alive as us and need to breathe! Instead of oxygen, these microbes breathe in iron and release electrons. By utilizing electrodes of carbon and connecting wires, the electrons can be directed to flow in a circuit and a living battery is created! These microbial fuel cells can be used to power remote scientific instruments in the ocean. Just how much power do we get from these batteries? Check out the sensor for yourself!
Art, engineering, and environmental science all combine forces to create the unique Atomic Jellyfish sculpture! The exhibit was created by Kerrville artist John Self using a wide variety of reclaimed materials. This jellyfish displays the hidden beauty that is revealed when bringing unlikely parts together and provides an innovative use for items previously considered useless.
What Do You See?
The bigger the better! Magnify your perspective of tiny animals and parts of plants in order to uncover their amazing intricacies. This exhibit allows all ages to discover!
New Kid Of The Blocks
You are the engineer AND the builder! Construct your own impenetrable fort, or sculpt a throne to rule them all. Which structures will stand and using what shapes? The possibilities are endless and even more fun with friends or family members to help you out! Mosey on over to the terrace outside and take in some fresh Johnson City air while building your own castle.
Fun with physics! This wheel versus wheel race to the bottom of the incline will leave players reeling as they try to figure out the best way to distribute the wheel masses in order to make their wheel travel faster. Experiment with inertia to manipulate the acceleration, and position the wheel just right to beat your partner!
Magnetic Ball Wall And Gear Wall
Double the sides, double the fun! Each side of this exhibit brings mechanics and engineering to life and represents some of the mechanical processes that moved grain around the historic Mill. On the Magnetic Ball Wall side, visitors will use levers, magnetic ramps, and a variety of other tools to maneuver a ball through the surprisingly complex structure. The other Gear Wall side engages visitors by challenging them to experiment with combining gears in different ways to move “grain” and turn the windmill. Creativity and problem-solving juices will be flowing as visitors take on the daily challenges posted for each wall!
Young Explorers (Toddlers Area)
The toddler space is an age appropriate, safe space in the Mill for infants and toddlers to play. Climbing structures, sensory objects, and crawl spaces are the attraction for visitors ages 0-3. Click here for more information.
The Dream TableTop makes learning computer science fun by teaching abstract computer science concepts in an exciting and innovative way! It is an interactive tabletop experience that combines puzzle pieces with virtual environments, allowing children to explore different combinations of physical puzzle blocks to create a variety of different virtual scenarios. Make the chameleon rainbow colored and wave, make it grow five times bigger and jump, or combine all of them together! There are many properties to explore in this rich learning environment (it’s fun for adults too!).
Visitors will adventure into another world in our state-of-the-art 3D theater, whether it be ten times smaller, in the depths of the ocean, or sometimes not even on this planet! Each 20-minute film shown will only be featured for a limited time.
Local high school student, Dalton S., takes K'NEX construction to a whole new level with his amazing and complex K'NEX sculpture! Located in the main lobby, the sculpture will mesmerize you right when you walk inside. The constant motion of the ferris wheel and tiny ball traveling through the structure is enrapturing--come see for yourself!
Normally you’re not supposed to play with your food, but the opposite is true here! Compose a masterpiece or play your favorite tune on our amazing Banana Piano. This science relies on the human body’s ability to conduct small amounts of electricity. Play any fruity tune your heart desires!
Touch Sound, See Sound
Do you love music? If so, you probably know that there is so much more to sound than just hearing it--you can feel and see it too! Touch a speaker and feel sound wave vibrations change as the frequency changes. Watch straws jump and dance to rock, classical and hip hop. The music is so moving that objects actually move!
Game Of Life
The surface of this interactive game is filled with ultrabright LED lights that respond to motion according to Conway’s Game of Life. Wave your hand over empty spaces to bring cells to life, and watch as this electric petri dish is animated according to Conway’s rules. See how you perform in the Game of Life!
Busy, Beautiful, Beneficial Bacteria
We always hear about how bacteria are gross and make us sick, but in reality most of them are extremely beneficial! In just these two columns, the areas of purple, green, and orange contain millions of different types of bacteria. Many of these non-dangerous, beneficial little microbes are necessary for the environment and for the health of animals, including humans. Use the app to play with and explore amazing bacteria!
