Sphere Presentations for General Audience


Solar System, Part I – The Rocky Planets

Venus_opt

Mercury, Venus, Earth, and Mars, the first four planets closest to the Sun are all displayed in brilliant, visual detail. As we take a tour of these “rocky” planets, so called because they consist of silicate rock and metal, we discover why physical differences among the planets makes them all so visually different. Visitors will also learn why the conditions on Earth make it hospitable to life – including us!

Solar System, Part II – Gas Giants

Jupiter_opt

Jupiter, Saturn, Uranus, and Neptune are the “gas giants” in our solar system. These planets are different from rocky planets because they are tremendously large and made mostly of gases, like helium and hydrogen. We will visit the gas giants and some of their more interesting moons. Pluto will be the last stop on our tour, and we will help explain why Pluto is no longer considered a planet!

Ocean

Ocean_opt

The ocean is tremendously important to our planet in terms of sustaining life. We will take a tour of the Earth’s ocean (it will be clear that there is, in fact, only one ocean!) to understand how it helps create weather, transport materials and nutrients, and provides sustenance for humans.

Dynamic Earth

Volcanoes_opt

The surface of the Earth is dynamic and constantly moving. Through fossils and geological evidence, we have been able to track the movements of the tectonic plates. The continents are part of these plates, and their movements have produced major changes both in the past and during the present day. Even though we are not usually aware of the plates moving beneath us, this motion can contribute to natural disasters, such as earthquakes, volcanoes, and tsunamis.

Weather and Climate

ENSO_opt

Energy, in the form of light and heat, is transferred from the Sun and blankets the globe. As this energy moves and interacts with other physical forces in the atmosphere, our weather and climate are created. Using modern technologies we can now look at historic climate and see how our climate today varies from what we might have seen in the past.

Water

Ocean Conveyor Belt_opt

Water is vital to life—over three-quarters of the human body is water. Photosynthesis in the ocean provides between 50–80 percent of the oxygen we use to breathe. So where does water come from, and why is it so necessary for living things? We will track the movement of water, in its various states, through the environment as a part of the water cycle.  We will also demonstrate the importance of conserving this natural resource.

Sun, Light and Life

SeaWIFS_opt

The Sun plays a critical role in providing energy for all living things on Earth. We will take a close-up look at the Sun, explaining how electromagnetic energy (visible light) from the Sun helps plants grow which, in turn, feed animals and ultimately humans. Lastly, we will look at ways to harness solar energy, helping provide sustainable energy for all living things on our planet.

Climate Change

Ice cap_opt

To understand what is happening to the Earth we must understand the major components that make up the Earth. We will view the five distinctly different “spheres,” representing air, water, rock, ice and life, which make up the Earth we know. The different spheres are atmosphere, hydrosphere, lithosphere, cryosphere and biosphere. We will also view the daily and yearly changes humans are making to our climate. Some potential consequences of climate change will be discussed but, most importantly, the audience will be given everyday solutions they can fit into their busy lives.

Population Growth

Crop-feed_opt

Human population is growing exponentially, and it is predicted to reach nine billion individuals by 2050. As population continues to grow, new land must be developed for housing, commerce and agriculture. Coastal areas are among the most densely populated, but populations will move inland as the coastlines become full. As we make changes to the landscape around us, how are we affecting other areas on the planet? Is there a way that human population growth can occur sustainably?

Biodiversity

Coral_opt

Life on the Earth is not evenly distributed. The ocean contains a vast array of biological diversity, but marine organisms are mostly found in specific areas. Visitors will learn about productive zones of the ocean including coral reefs, hydrothermal vents, and upwelling areas. Tracking chlorophyll, temperature, and currents, it becomes possible to identify why some areas of the ocean are biological deserts, and others are veritable buffets.

Elements of our Unique Earth

Precip-Water_opt

Four distinctive and yet inextricably linked elements – earth, fire, water and wind – interact to provide humans with the place that we call home. We live in relative comfort because of the balanced system created by their constant moving and mingling. Humans alter this system in ways that we can observe but do not yet fully understand. This presentation gives a new perspective on the elements that make earth hospitable enough to be our home planet.

Animal Tracking & Migration

NOAAB_opt

Scientists use satellite tags to track animal movement throughout the ocean. By tagging these animals we are given a glimpse into their migration paths and behavior. Knowing more about their behavior patterns close to shore or where animals over-winter helps scientists make more informed management decisions about those particular species. Come watch with us as we trace the journeys of sharks, turtles and seals.

Primary Productivity

Vegetation_opt

Sunlight is used by living things to create food. This transfer of light energy into chemical energy, and specifically carbohydrates, occurs through photosynthesis. All the “food” that is created is then used either by the plants (and producers) or by consumers as the energy is passed through the food web. Together we can track the primary production both on land and in the ocean and understand how important the role of each organism is in the food web.

Steward Sphere Presentations (Child Themed Presentations)


Water Cyclewater vapor_opt

When viewed from space, we can see that Earth is mostly water, yet most of it is not available for human consumption. Water, in all of its forms, is an essential resource for living things. We will follow the movement of water and learn why the water we depend on every day is only a tiny fraction of all the water available on the Earth.


Moving Earth

paleogeographic_opt

Ever wondered why South America and Africa look like two puzzle pieces that should fit together? Well, you’re right, because millions of years ago, they did! Even though we usually can’t tell, the ground we live on is constantly moving. Take a journey with The Sphere to discover how and why the surface of the Earth moves.


Life on Earth

sun_opt

Life is possible on Earth because of our Sun. The Sun provides us with heat and energy that plants can turn into sugars through photosynthesis. Plants in turn provide their energy to animals and decomposers through food webs. Let’s remember how important the Sun is in making our food the next time we are hungry!


Animal Tracking

Shark_opt

We know that most animals move, especially if they are hungry or looking for a new place to live. Come join us as we use data from satellites to follow the path of seals, turtles, and sharks–oh my!


Solar System Tour

SSystem_opt

You probably know all your planets, right? Well, we can help you learn more. You’ll be able to figure out how old you would be on Venus or how much you would weigh on Saturn. Let’s explore our solar system together!


Weather Tracking

weather_opt

Want to be a weather bug? We can help! In real time, we can track the weather across the globe. Together, let’s investigate the role of the ocean in creating large scale weather patterns like hurricanes and tsunamis.


Population on Earth

facebook_opt

For a long time the Earth was relatively unpopulated. Areas that people live in today would have been too cold, impossible to traverse, or wouldn’t have produced food. What changed? How did we go from a few million to over 6.5 billion people on the planet? How long did it take? Join us to answer these questions and more!


It’s Elemental

currents - temp_opt

How do these four elements – earth, fire, water and wind – help provide a stable yet ever-changing home for us?   We are able to call almost every part of Earth home and move all around our planet because of the interactions of these elements.  Come explore the connections among earth, fire, water and wind!

 

Kid’s Rule the Climate!

ocean acidification_opt

We all hear about “climate change” in school but what does it really mean?  Together we will become experts in understanding our atmosphere and the greenhouse effect.  We will also see daily and yearly changes that humans are making to our climate. Knowledge is power so we will provide you 10 easy solutions so you – yes, you – can help take control of climate change!
