  SKU #BAR-130
  When water moves up the spout, expect stormy conditions; when water moves down the spout, good weather is on its way. This hand blown glass bulb contains trapped air that expands and contracts with changes in atmospheric pressure. Since 1643, many seamen have used this simple device to predict the weather. The water can be dyed with food coloring. ~15 cm (6") tall.

  Like other reviewers have noted, no instructions can with barometer.
  Owner Response: Sadly, we have found that a few boxes do not have the instructions included with the barometers. We have added the instructions to the product page and will happily send them to you as an attachment if that would be easier. We apologize for the inconvenience.
  I can hardly wait to see how it performs but there were not any instructions in the box and I think I could put it together just by sight but I don't want to.
  Owner Response: Our apologies! There should be instructions in every box. I'm sorry they weren't included with your order. Someone from our Customer Service Team will be reaching out to you today, and we will send a copy out to you immediately.
  I recently purchased one but sad to say, no instructions. I am a big believer in read instructions first!
  Owner Response: Our most sincere apologies! We will send out instructions to you immediately! I think you will be pleased with the product once you have the instructions on how to set up your barometer.
  I broke the first one during assembly and was sent a replacement free. It is a cool barometer. Easy to see pressure changes.
  Owner Response: So happy it's working out well for you!
  the plastic tube became stuck in the glass tube and trying to pull it out broke the glass tube.
  A great classroom aid for my AP Environmental and Environmental Science classes to discuss air pressure. Students enjoy observing changes and using it to predict the weather.
  Students are fascinated and can't wait to look at it each day to discover the pressure
  great for teaching about air pressure and weather
  Students can use the Barometer to analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
  Students can use and share observations of local weather conditions to describe patterns over time. Students can apply knowledge gained from the Barometer demonstration to understand the power of air pressure and its effects on weather. (See Lesson Ideas)
  Students can ask questions to obtain information about the purpose of weather forecasting to prepare for, and respond to, severe weather. Students can apply knowledge gained from the Barometer demonstration to understand the power of air pressure and how Air Pressure is a factor in forecasting weather.
  Students can represent data in tables and graphical displays to describe typical weather conditions expected during a particular season. Students can apply knowledge gained from the Barometer demonstration to understand the power of air pressure and its effects on weather/seasons. (See Lesson Ideas)
  Students can use the Barometer in a plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object.
  Students can develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact. Students can apply knowledge gained from the Barometer demonstration to understand the power of Air pressure and how it interacts on Earth. (See Lesson Ideas)
  Students can use the Barometer to plan an investigation to provide evidence that the change in an object's motion depends on the sum of the forces on the object and the mass of the object.
  Students can use the Barometer in an investigation to define simple design problems reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
  Students can use the Barometer to develop and use a model to describe how unequal heating and rotation of the Earth cause patterns of atmospheric and oceanic circulation that determines regional climates. (See Lesson Ideas)
  Students can use the Barometer in an investigation to design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
  Students can apply knowledge gained from the Barometer demonstration (See Lesson Ideas), to use a model to describe how variations in the flow of energy into and out of Earth systems results in changes in climate.
  The Barometer will help students to feel the power of air pressure. Use it to teach students the 'truths' about air pressure, 'There is no suction!' Students can calculate based on the area of the mat and the standard air pressure to calculate how much force is required to pull the mat up.
  Students can use the Barometer in a number of different investigations on air pressure. Use spring scales to acquire quantitative data and make measurements of the pull. With the manipulation of variables, students get real world and inquiry engineering learning opportunities.
