- Marine Litter .... the usual suspects at my beach
  
  In this project students (or any other person) selects an area in the local beach and collect all the litre they can find. After this, the littler is cleaned, organized and separated according to its origin and category. By doing this, students not only clean their local beach but they identify the main sources of litre so as to create effective solutions to decrease it.

- Bees for the future_
  
  Travel to the heart of your community to discover the level of awareness of the importance to preserve bees in the ecosystem. Using provided questions, interview the experts about your island's flora and agricultural practices, and how they relate to the bee population; explore the data at a local and at a global levels using the data collected by your colleagues from different locations.

- Soil pH
  
  Soil is a complex ecosystem that is home to many organisms, which determine its fertility. The pH of soil affects the development of organisms that inhabit it and the solubility of minerals. Working together, we can map soil pH and, at the same time, find out if the color of the soil indicates its acidity.

- Searching for the Most Acidic Citrus
  
  Every citrus fruit contains organic acids, such as citric acid and ascorbic acid, also known as vitamin C. Yet limes or lemons taste quite acidic while oranges or mandarins are on the sweet side. Which among citrus fruits is the "world champion" in acidity? Is there a correlation between acid taste and pH-levels? Are there variations in pH for the same citrus fruit grown in various countries, regions or climate zones. Those questions will be explored in this activity.

- Noise Patrol: Day Watch, Night Watch
  
  Rarely do we take time to listen to how noisy our world can be. Stop and listen. What sounds do you hear? Day or night, quiet or loud, pleasant or abrasive - noise can be a form of pollution. Let's map noise levels and see what we discover.

- Which Berry is the Most Acidic?
  
  Berries differ by the amounts of sugar and organic acids, such as citric acid and ascorbic acid (vitamin C). Which type of berry is the most acidic? Is it true that the more sour a berry, the lower is its pH? Working together in this investigation, we will find out.

- Getting on the Same Page: Calibration
  
  When we look for answers in GlobalLab, we base our conclusions on data we all submit. But when we use probes and sensors, and since each of us uses our own instruments to collect data, how can we know whether our findings can be compared? How do we know our instruments even measure their target, in this case pH, or measure with comparable accuracy? What can be done so we can trust each other’s findings? For pH measurements scientists use a procedure called the calibration of pH probes. We check how accurately our probes and sensors measure pH by first measuring so-called ‘standard solutions,’ those with pH values we already know, since we either prepared them ourselves or purchased them from chemical catalogs.

- Does pH Go with the Fizz?
  
  What happens to unfinished soda? Many soft drinks are easy to tell apart by their tastes; they all are made from different recipes. But what they have in common is the presence of carbon dioxide. Compare the original acidity of soda with what happens to pH levels as the soda loses its carbonation and goes “flat”.

- Souring of the Milk
  
  Fresh milk right from the cow has a pH value that is almost neutral. Gradually, however, milk becomes sour, even when it is stored in a refrigerator. In this investigation we will see if we can tell how many days old the milk is simply by measuring its pH. We will also investigate the microorganisms at work in its change in acidity.

- pH & Temperature
  
  What if you measure the pH of a chilled solution that you just removed from the refrigerator, and somewhere else, others measured the pH of the same solution but at room temperature on a warm day? Does the temperature of a solution affect its pH? If so, what does this mean for our investigations into pH? Should we measure pH when the solutions are at the same temperature?

- Food Preservation and pH
  
  Sometimes people preserve fruits by adding water, sugar, and some spice to make a fruit preserve, and then putting the preserve in a tightly sealed jar. But when fruit preserves are stored in a warm place, they start fermenting, which is a chemical breakdown by microorganisms like bacteria, and they get sour. What does this process have in common with the souring of milk?

- pH of Your Local Pond or River
  
  Let’s check the acidity of the water in our river, pond or lake. Do pH levels change over the course of a day? Is there a relationship between acidity and eutrophication, when a body of water loses its oxygen and becomes a marsh?

- pH of Your Saliva at Rest and Under Stress
  
  Everyone can recall the dry mouth we experienced before a big exam or performance. Yet when we’re alone, especially before lunch, the saliva in our mouths is very different. We’ll compare the acidity of saliva before and after meals, when alone, and in stressful situations.

- The Water You Drink
  
  To avoid problems with your teeth or your health in general, the pH of tap water you drink should be close to neutral. But what is the actual pH of the tap water you drink? Does the pH of tap water change over the course of the day? Does it change day by day? Or after a large rainfall or snowstorm?

- Sweet Apples & Ripe Seeds. Is There a Relationship?
  
  Animals are distributors of seeds. They eat fruits and expel seeds, enabling new plants to grow far from the mother plant. The sweeter and riper the fruit, the more attractive it is to animals. But are seeds ready for germination when their fruits are most ripe? Let’s find out, using apples.

- Plant Whisperers
  
  Plants can sometimes reveal pH. This is because some plant can live only in soils with narrow and specific ranges of pH. We’ll explore whether we can tell the pH of the soil just by the plants that grow there.
