Activated charcoal is a good resource for teeth whitening, skin cleansing, in case of accidental poison ingestion, and spider bites and similar maladies.
Be introduced to activated charcoal, and learn how this all-natural substance is great for detoxifying or purifying your body. There's quite the buzz about it!
Soap contain alkali matter, which affects our skin and even skin may crack. To maintain the oily and moisture balance on our skin, fatty material required in soap.
In general the fatty matter in soap is approximately 70% to 80% .Fatty matter below 70% makes our skin dry, rough and skin may crack. Whereas percentage [%] of fatty matter above 80% makes the soap sticky and oily and washing becomes very difficult.
In this project, we investigate the amounts of fatty matter in different soaps.

really helpful for your projects try to do some work on your own to make it look more presentable i guess this is is enough to make you all know the importance of this project
soap is a salt of a fatty acid,.
Consumers mainly use soaps as surfactants for washing, bathing, and cleaning, but they are also used in textile spinning and are important components of lubricants.
Soaps for cleansing are obtained by treating vegetable or animal oils and fats with a strongly alkaline solution

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

How to make soap - Experiment for Chemistry lessons
1. Make you own soap - Practical
1. Introduction
Humans have been been making and using soap for at least 2300 years. In all that time the
manufacturing process has not changed much. Fats from animals or plants are reacted with sodium
hydroxide in a reaction called saponification where soap is produced and glycerol is a biproduct
(see Figure 1).
Figure 1: Fat and sodium hydroxide react in a saponification reaction to glycerol and soap
(= the sodium salt of the fatty acid).
Soaps are the sodium salts of fatty acids. It is the combination of the non-polar, long carbon chain
of the fatty acid and the polar, ionic end consisting of carbonic acid anion and the sodium cation
that let soaps dissolve dirt particles in water. The soap molecules are arranged around the dirt
particles in spheres called micelles as the non-polar carbon changes are drawn to the non-polar dirt.
The polar, ionic ends face the polar water and enable the removal of the dirt (see Figure 2).
Figure 2: Arrangement of a micelle made from soap molecules around a dirt particle in the middle.
Today almost all liquid body washes and some bar soaps do not contain actual soap any more.
Instead, they are made of soap-like molecules that are derived from petroleum and work the same
way soap does. However, bar soaps can be produced in a more environmentally friendly process
using only renewable sources and less energy.
You are going to make our own soap via a saponification reaction between vegetable fats (from
olive oils, coffee and coconut oil or cocoa butter) and sodium hydroxide in lye. This is how many
bar soaps are still made today.
2. 2. Materials
• Coconut oil or cocoa butter Depending on which smell you want for your soap. It will
give your soap its smell, and also provide fats that the sodium
hydroxide can react with.
• Olive oil The main fat that will react with the sodium hydroxide.
• Lye Sodium hydroxide solution in water of 25 mass-%, that can be
bought in the cleaning section of supermarkets.
• Coffee Not powder, the actual drink. This will provide the reaction
medium, but also some fats that the sodium hydroxide can
react with.
• Coffee grounds They are a filler that will give the soap bar the right
consistency. Other wise it would be too soft.
• Oat bran It is a filler that will give the soap bar the right consistency.
Other wise it would be too soft.
• Scale
• Thermometer
• Protective gloves Latex gloves will suffice, but you can also use nitrile gloves.
• Lab coat
• Lab goggles
• Glass stick, magnetic stirrer or stick or hand blender for stirring
• 1 large beaker for cooing or stainless steel pot
• Beakers or stainless steel bowls for mixing
• Measuring cylinders
• Spoon or spatula
• Soap mold A form in which you can pour the soap to let it set. For school
classes baking trays for muffins are suitable. One or two
students can share one spot on the tray.)
• Heating plate
• Baking paper
• Towels
• Sharp knife Only if students share mold forms.
3. 3. Procedure
The quantities used here will make soap for two students. They will have to be adjusted if larger
groups works together.
1. Using a scale, weigh out 48 g coconut oil or cocoa butter in a beaker. With a measuring
cylinder, measure 77 ml (71 g) olive oil. In a second one, measure 45 ml (45 g) coffee.
Weigh out 18 g lye in a beaker or bowl on the scale. Mix 1/2 tee spoon coffee grounds and
1 table spoon oat brain in another beaker or bowl.
2. Work under a fume hood or in another well-ventilated area. Make sure to put on lab coat, lab
goggles and protective gloves and keep them on until the soap is poured into the mold.
3. Pour the coffee in a beaker or bowl and carefully add the lye to the coffee, and stir to
dissolve. (Always add lye to liquid, not the other way around.) This will start a chemical
reaction and the mixture will get quite hot.
4. Melt coconut oil or cocoa butter in a beaker or stainless steel pot over low heat on the
heating plate until no solids remain. Add the olive oil. Check the temperature of the two fats
with the thermometer. Compare against the temperature of the lye solution, and adjust until
they are within a degree or two of each other, in a range between 40 and 45 degrees Celsius.
5. Pour the lye solution into the beaker/bowl with the oils, and use a glass stick, magnetic
stirrer or if you have a stick or hand blender to stir until the mixture begins to thicken and
the texture resembles pudding. Once the soap has thickened, stir in the coffee grounds and
oat bran with a spoon or spatula.
6. Slowly pour the mixture into a soap mold. Carefully, lift and tap the mold against the table a
few times to release air bubbles. Cover with baking paper, and then wrap the entire mold
with a towel to insulate it. As a soap mold for a school class baking trays for muffins are
suitable. One or two students can share one spot on the tray.
7. After 24 to 48 hours, remove the towel, and take the soap out of the mold. Let the soap loaf
sit for another day to harden further before cutting into bars with a sharp knife. Cutting only
needs to be done if students shared one form for their soap.
8. After the soap is cut into bars, you will need to let them cure in a cool and well-ventilated
area for four weeks. This allows the soap to finish saponification and for all the excess water
to evaporate.
