Stem fair project:

TOPIC: How salty does the water have to be to for a raw egg to float?

Question: How much salt concentration is required to make a row egg to float in water?

hypothesis or prediction: If i add enough salt to water , then the egg will float because the saltwater become denser than the egg.

Topic: The growing problem of space debris and why the Federal Communications Commission (FCC) should enforce stricter deorbiting regulations on satellite companies to reduce longterm orbital hazards.

Examples: space debris effects GPS. weather tracking, launching other satellite into orbit and so on. Basically how it effect the “environment”

The proposal must cover, in order:

Problem-prove the severity of the problem and its symptoms

Solution-detail who will take action, what they will do, and how it will work

Justification-address the strength and feasibility of proposal, compare to other solutions, and

show how the target audiences benefits outweigh costs

Format:

Style: APA(no title page or abstract required)

Length: 7-10 pages, not including References page (or title page or abstract if included)

Research: Minimum of eight (8) credible sources, including:

at least two new sources that were not cited on your Annotated Bibliography, highlighted on the References page

at least two scholarly journal articles or books published by a university press

at least one pop culture text (novel, music, film/TV, YouTube, podcast, game)

For the 1

st

essay you should

write

about the environmental problem

that youve

identified

.

You m

ust

discuss measurable

data

relevant to

the environmental

problem,

the

sources

of the problem

,

and

impacts

of the problem

(So youll need peer

–

reviewed

references).

Identify possible

actions

you

and others can take in the future

to solve the

problem. You must specify at least one action you are going to take during the semester to

reduce the impact of this environmental problem

For

your

action item you must identify an environmental problem and commit to take some

action to improve it. This action can be anything you can conceive of that benefits the

environment. The action must be approved by your instructor before you complete it and

s

hould be something that requires

several hours

to complete

beyond the time required to

write your essays and make your presentation

(i.e. something substantially more than

recycling your ES 103 syllabus at the end of the semester).

You must provide evidence that you have completed the action item b

y

the

presentation

due

date.

Evidence can be in the form of short videos, pictures, audio recordings, copies of

emails, letters, or anything that Dr. Gordon approves of (check with him first).

Both essays

should be at least 5 pages, double spaced, using Times 12 pt font, with one

–

inch

margins. References, tables and figures are not counted as part of your page count. You must

cite all sources using APA or CSE format (the format used in your plagiarism assig

nment)

My idea was to volunteer here in Evansville on the centers on reducing utility costs and managing our resources from the Ohio river. which would be things like fixing leaks, taking shorter showers and watering lawns. The EWSU (Evansville water and sewer utility) offers a relief program.

How much would it cost to prepare a review article in English for publication entitled Operationalizing Circular Economy for Food Waste Prevention: A Systematic Synthesis of Strategies, Metrics and System-Level Gaps, if I provide the literature myself? 9,00011,000 words are ideal. Including 46 figures/diagrams. 24 tables (e.g., strategy classification, metrics mapping, supply chain levels, etc.). 120180 references . I understand that 120180 references may be more typical for extended reviews exceeding 30,00040,000 words. However, in the case of systematic reviews within sustainability and circular economy research, it is not uncommon to see 100+ references within manuscripts of 9,00011,000 words, especially when the study involves structured screening, thematic synthesis, and system-level analysis.

My name is Eirini Kontaki and I am currently a PhD candidate working on the research topic entitled: Innovative strategies for food waste reduction in conjunction with the promotion of Circular Economy: A holistic supply chain approach. My dissertation focuses on the development and evaluation of innovative, applicable, and measurable food waste prevention strategies within a systemic framework that integrates Circular Economy principles across all stages of the supply chain, from primary production to final consumption. The dissertation will be written in Greek; however, the research draws extensively on international literature and aims to contribute to the broader academic discussion on Circular Economy operationalization and food waste prevention. The core objective of the research is to move beyond the theoretical discussion of the Circular Economy and contribute to its operationalization, with particular emphasis on food waste prevention and the clear distinction between prevention strategies and valorization pathways. In addition, the study examines structural gaps, potential trade-offs, and lock-in mechanisms that may hinder the systemic transition toward more circular food systems. The overall approach is holistic and cross-sectoral, aiming to develop an analytical evaluation framework that can be applied within different contexts of the agri-food and tourism value chain. The methodological foundation developed so far includes a systematic literature review, thematic categorization of strategies, supply chain-level analysis, and the initial development of a conceptual and analytical framework. However, the component currently under further development concerns the design of the empirical research phase. More specifically, I am seeking to define the most appropriate research strategy (qualitative, quantitative, or mixed-method approach), the data collection tools, sampling design, and analytical techniques that will allow the refinement and validation of the proposed framework. In this context, I am looking for specialized academic consultancy support, particularly in the methodological structuring and justification of the empirical design, the selection of appropriate research instruments, and the strengthening of coherence between the theoretical and empirical components of the dissertation. I retain full scientific responsibility and authorship of the work and seek a structured advisory collaboration aimed at enhancing the academic rigor and robustness of the research. I would greatly appreciate receiving information regarding your experience in Circular Economy and Sustainability research, the academic background of your consultants, and your proposed collaboration model.
