Exciting New Exoplanet Discovery

NASA announced this week that a new solar system comprising of seven Earth like planets has been discovered only about 40 light years from Earth. Named the TRAPPIST 1 system (after the Chilean telescope used to discover them), This system includes at least three planets that are considered to be within the 'Goldilocks Zone' that is "not too hot, not too cold, but just right!". The possibilities are that each of these three planets could be host to life as there is a strong likelihood of liquid water in existence.

While there are still many other factors that determine if life will exist there, the sizes and densities of the planets and their location relative to their star is an exciting possibility for astronomers and astro-biologists.

Newsflash: Liquid Water on Mars.

What We Knew

Scientists have for some time projected that water in liquid form had been abundant on Mars and through some environmental incident or over a course of time, that water has disappeared. A number of theories about why it went and what happened have been presented but Mars, the red planet, has been looked upon as more of a dessert.

It has also been known that there is a polar icecap on mars that contains some large quantities of frozen water. Rovers have also dug into the soil and evaporation of moisture has been recorded.

What we are finding out

The Curiosity Rover has already shed more light on the mystery of water, although it has not found any organic substances.

Without knowing too many details, it seems that there are periods during Mars' orbit of the sun that liquid water is prevalent on the surface of some areas of the planet.

What might this mean?

Im taking a long shot here, but it seems that out of our eight planets and few dozen moons in this solar system, at least two planets have been confirmed to have liquid water. Several of the moons are suspected to also have oceans under deep ice sheets. It seems that water, the elixir of life, is more prevalent in the universe than we had suspected.

Perhaps the odds of finding life have changed (for the better). Perhaps the odds of finding another world that would support life from this planet might also have improved. Perhaps life is closer than we think!

 

5 Ways to reduce Math Anxiety.

4097009340_0f8343edac_oAt this time of year the 'back to school' buzz is in full swing and everyone wants their child to succeed. If your student has concerns with math, then this may be the thing that they fear the most. For some students, math fills them with anxiety to the point that they will feign illness, skip class and do just about anything to get out.

As a parent or teacher, this can be a very serious concern but there are some things that you can do to help your child deal with their math demons.

  1. Be positive about math. As a teacher, I've spoken to many parents who tell me that they hate or fear math. Some openly admit that they can't do math and hence can not help their child. As the #1 role model of your child, that tells them that its okay to have a negative attitude towards math. It also excuses them from trying because if you can't do it, then why would they need it? Even if you can not actually help them solve the problem that they are doing, being positive will encourage them to try a little harder.
  2. Ask them to explain what they have been doing leading to the problem. Educational Psychologists have shown that teaching and explaining helps retention and cognition far more than listening to lectures or reading. The reason for this is that you can't just go through the motions. You have to actually think about what you are doing and how and examine why each step follows from the last. Being active and asking questions will force your kid to examine their steps and find any mistakes that they may have made.
  3. Use online resources. There are some excellent youtube videos online that explain procedures and give dozens of examples. Talking about the videos and writing out the steps with your child will help them understand what they are doing and why.  Not only that, it might help remind you of what they need to do so you can help them more!
  4. Avoid leaving the assignment to the last minute. Its easy to put off the thing that you don't like doing but if you know that your son or daughter has math homework and is avoiding doing it, help them by getting it done first. If they are less tired and stressed while attempting the assignment, they are more likely to be successful at it. If they have a good attempt at it and still can not do it, then they will have plenty of time to contact the teacher.
  5. Contact the teacher. As a teacher, I know that I prefer students to come to me before the deadline to tell me that they had difficulty. This isn't because its eating into my golf time, but because I can make more time to help your child if they come to me sooner rather than later. I would also try to encourage students to contact their teacher themselves. Some students find it difficult to ask for help, but keeping open lines of communication will help in the long run.

With a positive attitude, healthy communication, use of resources available and good timekeeping, your child can reduce the stress associated with math. While these steps may not turn your middle schooler into a math genius overnight, it may help them sleep better, enjoy math classes more and hopefully help their understanding as well.
