CO2 Control In School Classrooms - AirTest Technologies

2 Control In School Classrooms 1 of 3 CO ... CO2 Sensors will automatically regulate fresh air delivery so that over-ventilation does not occur. In fact if fresh air is being delivered from another location such as an open window, hallway or another unoccupied classroom, the sensors will react to this source of fresh air and adjust the ventilation rate accordingly. CO 2 control is also an ...

Ocean Acidification in a Cup | NOAA

This classroom experiment allows students to see the process of ocean acidification in action. It creates a carbon-dioxide rich atmosphere above a layer of water with a pH indicator in a cup. The carbon dioxide diffuses into the water and eventually raises the pH, which can be seen with the pH indicator. The website describes the processes of ocean acidification, the fast carbon cycle, and how ...

10 Hands-On Science Projects to Teach About Pollution ...

In this experiment, students water three separate plants with either water, a little bit of acid, and a lot of acid. Use either vinegar or lemon juice as the acid. After leaving the plants in the sun to grow for a few days, watering them as they go, students will assess the effects of the acid on the plants. (You will need to be prepared to lose two plants. All for the sake of science of course!)

The Deliberately False Greenhouse Gas CO2 Experiment ...

2017-08-24· The higher density of CO 2 skews this type of experiment in favour of the Carbon Dioxide mixture being warmer than the pure air bottle. This can be confirmed by using other gases which have densities heavier than air such as Argon as a replacement for the Carbon Dioxide in the mixed bottle. Argon isn’t even considered to be a green house gas and yet a similar warming effect will be seen due ...

Key Considerations for CO2 Monitoring in Educational Settings

2021-06-30· The experiments carried out in school classrooms in late summer involved the manipulation of indoor air temperature, as well as the outdoor air supply rate. Students' performance in tests was significantly improved when the temperature was reduced from 25°C to 20°C (77°F to 68°F) and when the outdoor air supply rate was increased from to L/s ( to cfm) per person. …

Note to Teacher: Global Warming Experiment

include Carbon Dioxide (CO 2), Methane (CH 4), Nitrous Oxide (N 2O) and Ozone (O 3). The problem is that their concentrations have increased dramatically in the last century due to human activity. When we burn fossil fuels to provide electricity for our homes and businesses or when we cut down trees these actions release Carbon dioxide in the atmosphere. This is making the earth very, very ...

Indoor Air Quality in Classrooms and COVID19 - CO2 Meter

Indoor Air Quality in Classrooms and COVID19. April 12, 2021. The effect of poor indoor air quality in classrooms has been known for years. Chronic illnesses, reduced cognitive abilities, sleepiness, and increased absenteeism have all been attributed to poor IAQ - specifically elevated CO2 levels. What's more concerning today is the effect ...

Ocean Acidification Experiment

This experiment is a neat way to see the different levels of acidity in common household liquids. Acids tend to dissolve things and taste sour, like lemon juice. The opposite of an acid is a base, which feels slippery and tastes bitter, like soap. With a homemade pH indicator you can test many liquids to see which are acids, and which are bases. The cabbage juice indicator will cause acids to ...

Science Experiment - Classroom Kits

Dry ice is frozen carbon dioxide (CO 2) Under normal atmospheric conditions, CO 2 is a gas. Only about % of our atmosphere is made up of carbon dioxide. Most of the air we breathe is nitrogen (79%) and oxygen (20%). Instead of melting, dry ice turns directly into CO 2 gas. It does not “melt” like water ice because it skips the liquid ...

The Carbon Dioxide Greenhouse Effect - AIP

The Carbon Dioxide Greenhouse Effect. In the 19th century, scientists realized that gases in the atmosphere cause a "greenhouse effect" which affects the planet's temperature. These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice …
