Volcanos in Maryland?

Jacqueline Sollers,
Explorer Extraordinaire!

Jackie, Branch Manager of the Eldersburg Branch Library in Maryland, has not only been on field trips to Oregon and Montana with the LPI - she has been to the Moon and Beyond! Well, not really, but she did attend the 2-day Explore! workshop, To the Moon and Beyond, in Maryland two years ago

Since then Jackie has shared Explore! programs at her own library, at state workshops, with home school groups, and at local schools. Go, Jackie! Below are some ways in which Jackie has used Explore! and some ideas for how you, too, can share the excitement of space science with your community!

"At the Eldersburg Branch, our most recent Explore! programs were Health in Space and Rockets. We had over 30 children. They made UV Man, and protective clothing for him. We made connections to astronauts and the need for protective clothing in space. We are doing a series of programs in September on astronauts.

"The Rocket Explore! program is very popular. We have repeated it numerous times, and in the last program we talked about how rockets are fueled. The kids conducted various experiments, like designing the external parts of a rocket using the canisters as rocket bodies. Before they fueled their rockets with Alka Seltzer, I had them draw their destination (planet) with chalk in the parking lot. They had to predict how much fuel their rocket needed to reach its destination. Then we added payload (small beads & paper clips) to the film canister.The children predicted how adding payload would factor into the fuel requirements for their rocket. After all the experiments, we discussed how NASA decides when to launch a rocket and what calculations are needed to launch a rocket to the Moon or Mars.

"In May I spoke to three 5th grade classes about volcanos and volcanic rocks. I took rock samples to pass around. The kids LOVED the rock samples! I covered the different types of volcanos with them, then the children got to make a volcano of their choice.

"This June, we did the Luna and Moona Lisa puppet show from To the Moon and Beyond! for the second time. We had over 60 participants. After the puppet show, the kids knew ALL the answers to the questions the puppeteers asked!! We also let them make a Moon mask after the show for fun."

Jackie has a blast learning and sharing about Earth and Space science with kids, teachers, and parents through the Explore! program! If you would like to contact Jackie for ideas or suggestions on how to enhance your programming through the use of Explore!, you may contact her at: jackies@carr.org

Becky Recommends!

As the activity designer for several of the Explore! modules, I am always on the lookout for great ways to engage children in Earth and space science. All activities in Becky Recommends! are designed for tight budgets and tight spaces, and are always educational and fun!

The following activity is the sixth in a series of activities on Health in Space. A more detailed version of the activity is available on the Health in Space website.

 

 

Bones of Contention!

What's Needed?

For each child:

  • 1 pencil (slightly sharpened)
  • 2 Styrofoam cups (the taller, the better)

Who?

Children ages 8-13

How Long?

15 minutes


Overview

In Bones of Contention! children make models representing bones on Earth and bones that have been in space.  They discover what happens to bones without proper exercise and nutrition!

Cups

Preparation

  • Younger children may need assistance poking holes in their cups
  • Distribute the materials

Activity

  • With the slightly sharpened pencil or stick, poke 5-8 holes, scattered randomly, in one of the cups, and about 25 holes in the other
  • Label the cup with fewer holes Bone on Earth and the cup with more holes Bone in Space
  • Stand each of the bones (cups) upside down on a flat surface
  • Place your hand, palm down, on top of the Earth Bone and gently press down. Is it difficult or easy to crumple?
  • Now, do the same to the Space Bone and observe how difficult or easy it is to crumple

In Conclusion

One of the biggest challenges facing space travelers is the loss of bone mass. Bones need physical stress (exercise!) to maintain their health. In microgravity, bones do not get the kind of workout that they do on Earth, and they deteriorate and fracture. To counteract this bone loss, astronauts must spend up to two hours every day exercising and they must get proper nutrition (for example, adequate calcium and vitamin D). And it is not just astronauts that need to get enough exercise and calcium. Kids on Earth do, too!

Mars Rover Opportunity’s skies darkening with dust

Scientists Keep an Eye on Martian Dust Storm
Modified from ASU scientists keep an eye on Martian dust storm

Scientists are monitoring a large dust storm on the Red Planet.  The dust storm, which erupted during the last week of June, is affecting operations for all five spacecraft operating at Mars. The fleet includes two NASA rovers on the ground (Spirit and Opportunity), plus three orbiters, two of which belong to NASA (Mars Odyssey and Mars Reconnaissance Orbiter) and one to the European Space Agency (Mars Express).  Beginning in the equatorial region west of Meridiani Planum, the storm moved into the heavily cratered southern highlands. It took roughly a week to grow large enough to spread around the planet south of the equator. Dust has now drifted into the northern hemisphere as well.

It is currently summer in the southern Martian hemisphere, when dust storms are more common.  For nearly a month, a series of severe Martian summer dust storms has affected the rover Opportunity and, to a lesser extent, its twin, Spirit. The dust in the Martian atmosphere over Opportunity has blocked 99 percent of direct sunlight to the rover, leaving only the limited diffuse sky light to power it. Scientists fear the storms might continue for several days, if not weeks.  Mars dust map images are available online at http://themis.asu.edu/dustmaps .

Water on Distant Planet
Modified from http://www.esa.int/esaCP/SEMBDZI2O3F_index_0.html

Scientists report the first conclusive discovery of the presence of water vapor in the atmosphere of a planet beyond our Solar System.  Astronomers used data from NASA’s Spitzer Space Telescope, analyzing infrared light as a previously discovered gas giant, HD189733b, passed in front of its star.  As the gas giant’s outer atmosphere passed in front of the star, the light seen showed that water vapor in the atmosphere absorbed some of the star light.

Even though this planet has water, it is not a good candidate for alien life.  Instead of a rocky planet like Earth, HD189733b is a gas giant, bigger than Jupiter but extremely close to its parent star, orbiting the star in only 2.2 days.  Its atmosphere is almost 1,300 degrees Fahrenheit!  Still, this discovery increases hopes for detecting water on rocky planets in the near future.

Pluto’s Moon Charon has Geysers
Modified from http://www.gemini.edu/icemachine

Astronomers have detected ice deposits on the surface of Pluto’s moon Charon.  The observations show fingerprints of fresh water crystals and some ammonia hydrates in patches on the surface, and suggest that liquid water mixed with ammonia from deep inside the moon is spewing onto its surface by geysers, through a process called cryovolcanism. 

Charon is very cold, about -650 degrees Fahrenheit.  That’s too cold, one would think, for liquid water.  In some thermal models of Charon, the antifreeze properties of ammonia result in reservoirs of liquid water deep beneath the crust.  Some scientists suspect that heat from internal radioactivity creates a pool of melted water mixed with ammonia inside the ice shell. As the water sprays out through the crack, it freezes and immediately “snows” back down to the surface, creating bright ice patches that can be distinguished in near-infrared light.

Cryovolcanism in the outer solar system is a fairly common occurrence. Enceladus (a moon of Saturn) and Europa (orbiting Jupiter) both show evidence of water ice oozing or spewing out from beneath the surfaces. Enceladus and Europa are tidally squeezed by the gravitational forces of their giant planets and in some cases by large nearby moons. This forces water out through cracks.  By contrast, Kuiper Belt Objects (KBOs) such as Charon, Quaoar, Orcus, and others are not tidally squeezed. Yet, they seem to show evidence of cryovolcanism.
