How to Make a Simple Weather Barometer

Looking for a science project for your homeschooled kids, or just something fun and educational for your kids to do?  This activity is sure to spark a bit of curiosity in your child, as it gives them the chance to play weather forecaster.  Predicting the weather may seem a bit like magic, but after a couple weeks of checking their barometer, they’ll have a much better understanding of how this can be done!

How to Make a Simple Weather Barometer

Step 1: Gather the things you’ll need. These consist of: Scissors, tape, a balloon, a jar, an elastic rubber band, a straw.

Step 2: Blow up the balloon carefully and then let the air out of it again. (This is to stretch it.)

Step 3: Cut the balloon in half. Discard the piece with the neck on it.

Step 4: Take the remaining piece of the balloon and stretch it across the glass or jar.Keep it stretched firmly across and seal it down with the rubber band, around the rim of the glass jar. To make an airtight seal, avoid gaps between the balloon and the glass.

Step 5: Tape the straw onto the balloon lid; the straw should be sitting one quarter of a way on the lid, with the tape about 2 cm or 1 inch from the edge of the straw end that is sitting on the balloon lid. The straw is your indicator “needle”. Trim the straw if it’s too long, but leave more length off the jar as what is attached to it.

Step 6: Put the finished glass jar next to a wall and tape a piece of paper or card to the wall behind it.

Step 7: Mark the current position of the straw on the paper, and mark one above and below the mark, about the same length away, and label the high and low pressure. Arrange the paper so there is room above and below the straw for you to make more marks when the straw moves.

Step 8: Check the straw regularly and keep marking its location on the paper for a few days. Add notes that tell you what the weather is like (for example, “rainy,” “windy,” or “sunny,”) next to the mark.

  • Examine the paper after several days. Check the markings and the weather statements you’ve put next to them. What do you notice? Can you tell if and when the weather is about to change? See “Tips” for the answers.

Q&A

  • Does the barometer have to be outside?  Yes, it is very important to leave the barometer outside so that it can record more effectively.
  • What can a barometer indicate about the weather?  A barometer can only measure air pressure, giving an indication of the expected weather during the following 24 hours. Simply put, high pressure is likely to drive rain bearing clouds away, low pressure will likely let it in, leading to precipitation (rain).
  • Why do we blow up the balloon before using it?  To stretch it out. If you just pull the two ends, you can rip it and you will have to get a new one.

Tips:

  • As the straw moves up with higher air pressure, the days should be sunnier. As the straw lowers, the skies may be looking gray and you should expect cloudy or rainy weather on the way.
  • When you fitted the balloon over the glass, you captured air under a certain pressure. The balloon now indicates changes in the atmospheric pressure, that is, the pressure of the air around you. Higher air pressure pushes the balloon into the jar and makes the straw go up. Conversely, the air inside the jar expands against lower pressure and will bulge the balloon, moving the straw down. The straw makes it easier to see the motions of the balloon.
  • Also notice that the straw moves up or down just before a weather change since a change in weather typically coincides with a change in the atmospheric pressure.
  • Try to take each reading at the same temperature, since air expands when heated and contracts when cooled, which would also move the straw-indicator.
  • Check your results against the pressure from weather reports for your area. If you didn’t do it correctly, keep trying until you get it right.
  • Try this over a longer period of time if you’re having a week of rain or a week of sunshine. Try to choose the seasons likely to bring the most changes during a short period of time in your part of the world.
  • This is a delicate item. Place it away from foot traffic and daily activity.
  • Don’t leave the balloon in direct sunlight; this will wear it out and can affect the experiment.
  • Make sure there are no gaps or air holes in the balloon during the experiment; this will affect the outcome.

How To Naturally Improve Concentration and Focus in Your Child

Whether you’re a homeschooling parent or not, you have likely struggled with the issue of a child’s lack of concentration at some point during your parenting years.  Of course we know that children are curious, energetic discoverers.  This is natural.  However, some children struggle more than others.  Many frustrated parents don’t know where to turn for help.  What if there were some simple antidotes and tools you can use to improve concentration?  There is.  Of course no solution will work for everyone, but we think you’ll find the following suggestions extremely helpful.  Your sanity will thank you!

How to Naturally Improve Concentration and Focus in Your Child

So, how can you motivate and improve your child’s focus?  There are several different tools available.  In the beginning, it’s best to try them all to see what works best for you and your family.

1.) Attend to physiological needs.  Ensure your child gets 9 hours of sleep every night.  Reduce sugar intake & increase protein levels (lean meat, almonds, & eggs).  This stimulates dopamine which makes concentration easier, particularly for lethargic kids.  Taking frequent breaks for exercise will have a similar effect.

2.) Remove distractions at home.  Make a list of things that may prevent concentration (i.e. noise, people, lighting, fighting, tiredness, & hunger). Then go through each distraction and come up with a solution.  Make sure you implement those solutions daily!

3.) Create the right mood for concentration.  Playing calming background music, placing a fish tank (with fish) in the environment, and reducing fluorescent lights have all been proven to be successful in creating the right mood.

4.) Introduce sequencing & organization activities (i.e. following recipes, setting the table, and putting things in alphabetical order.)  Board and card games help as well.  Chess has proven to be particularly good for improving focus long-term. Their minds become incrementally stronger, alleviating the concentration problem, and in many cases, almost entirely curing it. The study of chess also instills patience and can help a child’s attitude.

5.) Find out which activities your child focuses on best.  Some kids do best with hands-on activities, and some do best with a lot of visual cues.  Look for activities that your child gets lost in for hours.  These activities can enhance your child’s concentration levels.

These are only a few of the tools we’ve found helpful through the years.  I’m sure there are many more that you’ll find that will work in your home. Before assisting your child with their concentration habits, pay close attention to their pattern of concentration and observe if there are any obvious links between diet, energy pattern, sleep, and your own behaviors.  Remember to lead by example!

Concentration can be improved and made automatic.  Picture the first time you drove a car.  No doubt the prevailing, panicky thought in your head was, “How on earth can I focus on all of this stuff at the same time?!”  After enough practice, your brain built pathways of concentration, and the task of driving has become a smooth and easy one.  Take action today and make the process of learning a lot more enjoyable for both you and your children!
