8 Ways to Use Your Phone as a Scientific Instrument

By

 


1. Earthquake detector (MyShake)

This will be especially useful to any of you living near a fault. MyShake can detect seismic activity using nothing but your Android phone. The app’s special algorithm picks out an earthquake shake from other types of movement.

If enough people install it, the University of California, Berkeley team that created it hopes to use it as an impromptu early earthquake warning system as well. An iPhone version is apparently in the works but not ready yet.


2. Spirit level (Google/iOS)

Your smartphone comes equipped with an gyroscope that knows how flat or tilted the device is. Several apps can easily take advantage of that, the easiest of which is built directly into Google: try typing “bubble level” into the Google search bar on Android or iOS to bring up simple level tool.

There are plenty of dedicated apps you can use instead, not least the one built into iOS. Launch the Compass app and swipe to the right to find the spirit level. (You may be asked to calibrate your iPhone before it works.)


3. Skin cancer scanner (MoleScope and SkinVision)

Using a bulky camera lens clip and an Android or iOS app, MoleScope lets you examine skin moles exactly, just as its name suggests. The app scans and tracks suspicious moles on your body and guides you through a self-diagnosis process.

You can also send off scans to a qualified dermatologist. If you want to stick to an app without an accessory, then SkinVision is available for Android and iOS devices and promises just as high a level of accuracy.


4. Heart rate monitor (Instant Heart Rate)

Plenty of wearables—from wristbands to chest straps—can monitor your heart rate, but you can do it with your phone too if you have a suitable app installed. Instant Heart Rate, available on Android and iOS, is one of the best.

It works by scanning the changing color of your fingertip through your phone’s camera and working out your current heart rate accordingly. It’s not the most elegant solution, but it works—and with no additional hardware.


5. Microscope (Micro Phone Lens)

Born on Kickstarter, the Micro Phone Lens gives your smartphone’s camera a whopping 150x magnification boost, allowing you to use it as a portable microscope (it works best when used with samples on microscopic slides).

The small accessory you stick to your phone’s camera lens can apparently function with any camera rated as 5 megapixels or higher. If you just want the adhesive-free lens itself without any accessories, prices start at $30.


6. Sound level meter (Decibel Meter Pro)

Apps like Decibel Meter Pro ($1 for iOS) use your smartphone’s microphone to turn your handset into a sound level meter—though accuracy may vary depending on the quality of your handset.

Those of you on Android might want to try the free Sound Meter instead. There are several other alternatives to experiment with. Useful for reporting the neighbors for being too loud late at night, at least.


7. Thermometer (Thermodo)

It’s likely that your phone already has thermometers inside it, but ones designed to measure internal component temperatures. To get an accurate reading on the air around you, you need an external sensor like Thermodo.

It plugs into the headphone jack on your Android handset or iPhone and then works in tandem with the companion app to tell you exactly how hot or cold it is in your current location. The cheapest Thermodo sells for $30.


8. Baseball speed detector (Radar)

This one is only “coming soon,” but it’s still worth mentioning: the successfully Kickstartered Scoutee combines an app and a small detector device, giving you an on-the-go speed radar for measuring pitching speed.

The kit lets you log speeds and record videos, save and analyze pitch parameters and game results, and of course share stats with the wider world. If you missed the crowdfunding campaign, the pre-order price is $170.

Masks in classrooms

Dr. Lin: Now, as far as masks inside the classroom, I know that there’s been some debate.

I would say that we should keep the mask on inside the classroom and the reason is, we have these asymptomatic virus producers, these virus factories, they don’t have any symptoms, but they can make viruses.

So without a mask, just by breathing out, they can send the virus maybe two or three feet away from them just by breathing. But if you put a mask on, then it cuts it down to maybe just a couple of inches away from them.

So you can contain somebody that has virus from spreading it around within the classroom by having the mask on all the time.

Now, if you’re a person without the virus, then having the mask on will reduce your sucking power. So that means you physically have to be closer to the virus before you can suck the virus into your lungs. And so, therefore, keeping the mask on will protect you as well because you’re less likely sucking the virus.

IPCC (Intergovernmental Panel on Climate Change) has issued it’s bleakest report so far – how to make a difference

The IPCC (Intergovernmental Panel on Climate Change) issued a bleak report on the state of the Earth’s panel.  

Increased heatwaves, droughts and floods are already exceeding plants’ and animals’ tolerance thresholds, driving mass mortalities in species such as trees and corals. These weather extremes are occurring simultaneously, causing cascading impacts that are increasingly difficult to manage. They have exposed millions of people to acute food and water insecurity, especially in Africa, Asia, Central and South America, on Small Islands and in the Arctic.

To avoid mounting loss of life, biodiversity and infrastructure, ambitious, accelerated action is required to adapt to climate change, at the same time as making rapid, deep cuts in greenhouse gas emissions. So far, progress on adaptation is uneven and there are increasing gaps between action taken and what is needed to deal with the increasing risks, the new report finds. These gaps are largest among lower-income populations. 

Are there ways that students and teachers can make a change to protect the Earth from run away heating?

The study found that sticking to six specific commitments – from flying no more than once every three years to only buying three new items of clothing a year – could rein in the runaway consumption that is partially driving the climate crisis.

The research carried out by academics at Leeds University and analysed by experts at the global engineering firm Arup and the C40 group of world cities, found that making the six commitments could account for a quarter of the emissions reductions required to keep the global heating down to 1.5C.

How do plants eat light? Do plants have a favourite flavour of light?

Plants need light to preform a chemical reaction known as synthesis.  Plants first need to capture light.  How is light capture preformed by plants?
