Favelas in RJ state are often located on hills, which served as refuge for enslaved people - after the abolition of slavery (1888) - and immigrants, who worked for downtown citizens. The Law of lands (1850) prevented unoccupied lands to be owned through labour and provided government subsidies for the arrival of foreign settlers to be hired in the country, further devaluing the work of black men and women. As a result, favelas today are mostly composed of a black population, surviving decades of persecutions and low incomes while defending, preserving and creating a unique culture rooted in African origins that reverberates into music and the arts. Children in favelas, due to social and economical inequality and racial discrimination, have less possibility of personal development and professional realization. They attend public schools where in 2021, according to SAEB, students do not reach a satisfactory level in Portuguese language (69%) and math (95%).

They hardly have access to after-school courses and do not tend to see themselves represented in the academic community. This produces a disadvantage in access to higher education and consequently in opportunities for decent employment. The project Closer to the Sky aims at co-producing scientific knowledge in collaboration between astronomers and artists/educators living in the favela of Cantagalo Pavão Pavdosinho (PPG, RJ, Brazil), for children, teenagers and young adults of the community. We will work in close collaboration with the social project Ninho das Aguias, where classes and night sky observations will be held.
Offering extracurricular courses and cultural experiences to students in the PPG, we wish to enrich their school curriculum and strengthen the chance they wish to stay in education after secondary school. A key element of the courses is providing positive role models of scientists from Afrodescendant backgrounds, reinforced by the presence of local artists and educators, thus endorsing their role within the academic community. The project also creates just work opportunities for local artists and educators, who will offer workshops rooted in favela culture, while at the same time creating novel, decolonial courseware based on contextualized science, i.e materials that use the context of marginalized societies as examples where we can understand, learn and make science. The material developed within the project will be shared as Open Educational Resources in several languages.

Place-making practices refer to the ways in which people create and define physical spaces as meaningful and significant through their everyday activities and social interactions.[1] In Ethnography, the study of these practices is often referred to as ‘ethnography as place-making,’ which involves the exploration of the cultural meanings and practices that shape the physical and social environments in which people live. This can include examining how people create and maintain social boundaries, how they express their identities and values through the built environment,[2] and how they negotiate power and control over the spaces they inhabit.

This place in Gröpelingen is made a place through the interaction of the people tending to the urban gardening project.

The authors structure their argument around three metrics: student health, student thinking, and student performance. They define these as follows:

• Student health: the overall physical and biological health of a school building occupant.
• Student thinking: short-term impacts on cognitive function and mental well-being.
• Student performance: the successful long-term academic performance of students.

Through their review of more than 200 studies, they conclude that there is unambiguous evidence for negative effects of low environmental quality on all three of these metrics. Although it is discussed in less detail, they also reference studies that provide evidence for the improvement of these three metrics when issues with school infrastructure are addressed.

"Millions of K–12 students in America spend several hours a day learning in schools that are more than 50 years old and in need of extensive repair and where children may be exposed to mold, poor ventilation, uncomfortable temperatures, inadequate lighting, and overcrowded, excessively noisy conditions."

Emphasizes the scale of the issue--this is not a Philadelphia or Santa Ana or Azusa problem, it is a national issue for all public schools. Also emphasizes the breadth of the issues--there are so many different forms of environmental hazards in schools.

• Ventilation & air quality:
• Children breathe more air than adults relative to their body size
• Water quality:
• Contaminants like lead have greater effects on cognitive development and behavior of children than adults
• Thermal comfort
• Current models for thermal comfort are based on adults and do not predict children's comfort levels
• Children are more susceptible to the effects of heat stress
• Children's clothing and activity levels (major determinants of thermal comfort) are distinct from adults
• Lighting and views
• Children have larger pupils than adults
• Children have greater light-induced melatonin suppression--their Circadian rhythms are more susceptible to manipulation
• Noise
• Children under 15 are more sensitive to difficult listening conditions because they are still developing mature language skills
• Children need a greater signal-to-noise ratio in order to understand language
• Memory and attention development are sensitive to chronic noise exposure

"We recognize that beyond the four walls of the school building there are many environmental and social contexts that can adversely affect students’ well-being and undermine their academic potential. Inequities persist in the distribution of the social determinants of health, and students bring these influence with them every day when they walk through the doors of their school building."

Environmental injustice can't be an either/or issue of hazards inside or outside schools, it needs to be a both/and issue where hazards in schools are being addressed in conjunction with hazards outside of schools.

"The chronic impacts of a poor school environment often do not get the same type of attention as cases like these, because the links between building quality and health are subtler and less overt."

"These" is referring to a list of dramatic incidents where students were suddenly exposed to some kind of environmental hazard. This quote captures one of the biggest challenges of environmental justice work--in the many, many cases where it is not visible, it is hard to mobilize support, attention, and emotion because the links aren't flashy. This connects to ideas about slow disasters in Anthro 25A.
