Exploring weights

Here’s a riddle for you to try on the kids:

Which is heavier? A loaf of bread or a single bread shaped and sized brick?

You have a minute. Think hard. Read the question again. Understand it. Take your time, within the minute of course. Hmm….ready. Spit out the answer!

Visually they might not look very different from each other. Try picking up a loaf of bread. Easy peasy. Now pick up that similar sized brick. Oops, not as easy as scooping up that loaf, right?

The brick’s definitely heavier.

Here’s riddle-2 about weights. Yep, a weighty day. Today. Which is heavier? A pound of rocks or a pound of loose cotton?

Visually they look very different. The pound of rocks occupies some space, but the pound of cotton – it looks like a tiny mountain! Go on, take a guess. Which is heavier? Most people would see the visual clue and forget about what was said. They would opt for cotton which occupies more space, and therefore seems the heavier one. Oops wrong again.

Both weigh the same. Remember? A pound was mentioned in riddle 2.

Illusion?I

Why does this happen? It’s an illusion, which was observed and stated by a physician in 1891, and therefore got his name and is called the Charpentier illusion. It explains how two brain systems behave differently to create the illusion and have it persist. Some of it is actually still a mystery.

Why get the kids to try this?

Such experiments help kids explore and understand their surroundings with little effort required in setting it up. All such learning leads to kids getting curious about their surroundings, helping their creativity bloom. Also, playful learning is not easily forgotten as the kids explore and learn on their own, frequently getting others to try it, reemphasizing the learning. What we look at as play, is serious learning which the brain uses throughout our lives to come up with ideas and solutions.

3 Great STEM Blogs You Should Read

The Net has a lot of STEM blogs, but a few really stand out for their creativity, educational value and never-say-die-curiosity! Yes, STEM blogging is about being curious about everything around, wanting, no needing actually, to understand the wonderful world we live in.

It’s easy to organize some homework help for older kids, but our younger ones need more creative activities.

U.S. Air Force Col. Lance Whitfill, 97th Mission Support Group commander, looks on as a student controls a robot, December 6, 2016, Altus Air Force Base, Oklahoma. The STEM initiative hopes to inspire the next generation to take an interest in science, technology, engineering and mathematics. (U.S. Air Force Photo by Airman Jackson N. Haddon/Released).

So here are 3 blogs which do this very well –

  1. Babble Dabble Do

This is a very colorful blog with lots of activities which incorporate science and art. There’s science, engineering and design nicely categorized for for parents and caretakers.

2. Teachers Are Terrific

Great place for doable, easy and kid-tested STEM resources. Although primarily meant for teachers, others can also use it.

3. Little Bins Little Hands

Want a wonderful slime recipes for kids? This is the right place. Kids will love their cool recycling ideas. Some of their droid activities are wonderfully imaginative.

Keep such lists handy and use them as reference when you need to pull out a STEM activity as magically as a rabbit out of a hat.

Flowering plants remain viable after passing through the guts of waterfowl — Why Evolution Is True

Quote

We’ve long known that plant seeds can remain viable not only after floating a long time in fresh or salt water, but also when passing through the guts of birds, including waterfowl. In fact, I believe that at least half of the plants that arrive on oceanic islands, later to form new species, come from […]

The Role and Responsibilities of a Research Scientist

Research Scientists are in charge of structuring, undertaking and breaking down data from controlled lab-based examinations, investigations and preliminaries. They may land jobs in labs, ecological associations, pro-research associations or colleges.

What does an exploration researcher do?

Research researchers work in pretty much every region of science possible. They plan and do tests and examinations in a scope of regions, including geoscience, medicinal research, meteorology and pharmacology. These are expansive research regions; an exploration researcher will in all probability be taking a shot at a considerably more pro-theme, for example, gravitational waves or undifferentiated cell science. In the event that your specialism is probably going to be science-based, investigate our exploration physicist expected a set of responsibilities.

An exploration researcher’s work is as a rule lab-based, with duties that include:

  • Organizing and directing examinations
  • recording and breaking down information
  • completing hands-on work, e.g. gathering tests
  • introducing results to senior/other research staff q
  • archiving research papers, reports, audits and rundowns
  • exhibiting methodology
  • planning research proposition and subsidizing applications/offers
  • managing junior staff including professionals
  • sorting out item/materials testing
  • guaranteeing quality guidelines are met
  • liaising with research as well as creation staff
  • creating unique answers for issues
  • staying up with the latest with applicable logical and specialized improvements
  • instructing

The usual managers of research scientists and sponsors for development are:

  • Government labs
  • Ecological organizations
  • Utility suppliers
  • Pro-research associations and consultancies
  • Open subsidized research gatherings
  • Colleges
  • Private sustenance organizations
  • Materials organizations
  • Buyer items organizations
  • Pharmaceuticals companies
  • Compound organizations

Research posts, especially those with perpetual contracts, draw in solid competition. Opportunities are promoted through the web, or vocations administrations, in national papers, in important logical productions, for example, New Scientist, Science, Nature, Chemistry World and in diaries distributed by the expert organizations. Theoretical applications are prudent, for which catalogues, for example, Current research in Britain might be helpful.  

An important postgraduate capability (a PhD/inquire about based MSc) is also typically required, especially for stable situations. Post-doctoral research as well as pragmatic research/lab work encounter is additionally valuable, and every now and again required for scholarly posts.

Key abilities for research researchers

  • Persistence
  • Assurance
  • Logical and numerical abilities
  • Adaptability
  • Definitiveness
  • An intelligent and autonomous personality
  • Fastidious tender loving care and precision
  • Organizational skills
  • Social abilities
  • Relational abilities
  • Communicational abilities
