The document is a project report on detecting the presence of basic radicals in different chocolate samples found in the market. The student conducted experiments on Dairy Milk, KitKat, Milky Bar, OneBar, and Snickers chocolate bars using cobalt nitrate solution. Grey ash was observed in all samples, indicating the presence of calcium. The conclusion is that while chocolate provides some health benefits, it also contains sugars and fats, so moderation is important. References are provided from Wikipedia and research websites.

Exercise 1: Data Interpretation
Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of ppm (parts per million). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below.
Post-Lab Questions
1. What patterns do you observe based on the information in Table 4?
General Chemistry 1_Module 1.pptx
General Chemistry 1 Module. Discussion on the different properties of Matter. Models of atom and history. Different orbitals and spdf notation. Identification of Atomic Mass, Weights, and Abundances of Isotopes.
What's the Matter?
The document provides information for an introductory chemistry unit titled "Matter and Measurement". It includes:
1) Learning objectives around systems being organised and developing methods for classification, measurement, and hypothesis testing.
2) Details of assessment tasks involving a unit test, science communication activities, and laboratory experiments.
3) An orientation to lab safety rules and equipment.
4) An assignment for students to create a science demonstration on water changes of state for younger students.
5) Guidance on the scientific method and variables to consider in experimentation.
Real‐time experiments for the acquisition of science competencies: COMBLAB pr...
The document describes COMBLAB activities, which are real-time experiments designed to help students acquire science competencies. Two sample activities are provided. Activity 1 involves using an ice-salt bath to make ice lollies without a freezer by cooling test tubes of water, orange juice, and sugar solutions. Students will design experiments, collect temperature data over time, and analyze the results. Activity 2 compares the efficiency of different antacids by simulating stomach conditions and measuring pH changes during acid neutralization. The activities are inquiry-based, focus on concepts like state changes and pH, and promote skills like experiment design and data interpretation through hands-on lab work and group discussions.

This document summarizes an undergraduate biophysics lab course where students designed and conducted experiments involving lipid bilayers and vesicles. In one experiment, students used fluorescence spectroscopy to study phase transitions in lipid bilayers containing varying amounts of cholesterol. They analyzed changes in fluorescence emission spectra to determine the gel to liquid crystalline phase transition temperatures. In another experiment, students attempted to build a homemade Brewster angle microscope using 3D printed parts to study lipid bilayers. The course aimed to teach experimental design, measurement, and troubleshooting skills through hands-on lab work with lipid systems.

It also provides an overview of the exam structure and what students need to know to pass.
Q2 Week1 Steps_of_Scientific_Method_PPT.pdf
The document outlines the steps of the scientific method and provides an example of a student, John, conducting an experiment to determine how the amount of sugar affects the rising of bread. John works through defining the problem, formulating a hypothesis, designing an experiment that includes independent and dependent variables, a control group, constants, trials and collecting/analyzing the results. John's hypothesis that more sugar leads to higher bread is initially rejected but then accepted after a second experiment testing amounts between 50-100g of sugar, finding that 70g of sugar produces the largest loaf.

The first trimester covers nutrition in humans, including movement of materials in and out of cells, human digestion and absorption, pathogens and defenses. Students will do lab work on osmosis in potato strips.
The second trimester focuses on transport systems, including circulation, the heart, blood vessels, blood composition and the excretory system.
The third trimester addresses maintenance of organisms, covering the nervous system, homeostasis, temperature regulation, and lab work on insulation.
Every plate tells a story nano y santi
The document describes a meal of potato gnocchi with tomato sauce and cream that contains processed sugar. Two of the ingredients were packaged in plastic. No food was thrown away from the plate. All items on the plate came from Argentina. The document then discusses the impacts of plastic pollution in oceans, how plastics can be toxic if inhaled or absorbed, and how turtles sometimes mistake plastic bags for jellyfish. It notes that microplastics pollute the environment and plastic ends up in islands. A video is provided showing the container that was made for storing items.
Every plate tells a story, pili and clari
The document discusses Clari and Pili's plates of food and their packaging, and examines the food in relation to the UN Global Goals. Clari had chicken nuggets and fries packaged in 3 plastic bags, while Pili's homemade pizza was in 8 plastic bags for its ingredients. They determine their food waste nothing and was all produced locally. The document then discusses the differences between linear and circular economies as well as causes, effects and solutions of plastic pollution, providing a link to additional information.
Every plate tells a story, nina, rochi, juana
This document discusses a meal of milanesa with rice and analyzes it based on several sustainability criteria. It examines the amount of processed sugar, plastic packaging of ingredients, food waste, and local sourcing of items. Several goals are identified for each criterion. Plastic pollution is also investigated in depth, outlining where plastic ends up, causes like overuse and fishing nets, effects like disrupting food chains and polluting land and water, and links to SDG 14 on life below water. Solutions proposed include redesigning packaging to transition to a circular economy. The document concludes by summarizing two science projects completed on recycling and the circular economy.
