This document discusses the structure and properties of matter. It begins by explaining that matter can exist in different states - solid, liquid, gas - which have distinct properties related to their shape and volume. It then describes how, at the atomic level, matter is composed of atoms bonded together through ionic, covalent, polar or hydrogen bonds. These chemical bonds involve the sharing or transfer of electrons between atoms to form molecules or compounds. The document provides examples of different types of molecules formed by these bonds, such as water and methane. It concludes that classifying and understanding matter at both the macro and microscopic scale is important.

Voyageurs National Park Lyle Mine Remediation: Part 1-Environmental AssessmentLoren Larson, CHMM, CPEA
Between 2002 and 2009, the Alliance of Hazardous Materials Professionals - North Star Chapter (AHMP-NSC) conducted numerous volunteer projects at Voyageurs National Park through its CHMMunity program. Members of the chapter volunteered their technical skills to complete specialized projects at the Park.
One such project was the Lyle Mine Remediation. The Lyle Mine was a historic gold mine located on a small island in Rainy Lake. The vertical shaft had been used as a dump and had filled with water creating a significant hazard. This presentation covers the first phase of the project, which included an environmental risk evaluation and environmental monitoring. Based on this information, the North Star Chapter members returned the next year to complete a drawdown of the pit and permanently seal the mine shaft to eliminate the hazard to visitors.
Visitors to the Park can reach the island today by boat. You will find a "bear box" there with a plate thanking the members of the North Star Chapter for their efforts.
Taking his sermon by the Book of 2 Timothy 2:3-4, Bro. Chika Chikwendu admonished the brethren to exhibit qualities of soldiers in their service to God.
He discussed on that as good soldiers, Christians should exhibit the following qualities:
1. Be Good Followers of Christ,
2. Be Faithful in Service of Christ,
3. Should Possess Sound Knowledge of God, and
4. Be Determined Fighters.

Addressing Unconscious Bias in Higher EducationJulia Michaels
Providing unconscious bias training to faculty and staff may reduce discrimination and the impact of bias at the university. Although evidence-based training models exist, effective implementation of those models is critical. Some universities have found that mandatory training can incite backlash, while voluntary training is unlikely to reach those who need it most. In addition, not all biases can be addressed at once; separate trainings are needed for racial bias, gender bias, disability bias, etc. During this webinar, experts on unconscious bias training will share evidence from their research, describe effective models, and discuss challenges for implementation. The speakers will also discuss remaining research gaps that limit the applicability of unconscious bias interventions across different contexts (e.g., admissions) and next steps for expanding the use of this promising practice.

Hamdard Laboratories (India), is a Unani pharmaceutical company in India (following the independence of India from Britain, "Hamdard" Unani branches were established in Bangladesh (erstwhile East Pakistan) and Pakistan). It was established in 1906 by Hakeem Hafiz Abdul Majeed in Delhi, and became
a waqf (non-profitable trust) in 1948. It is associated with Hamdard Foundation, a charitable educational trust.
Hamdard' is a compound word derived from Persian, which combines the words 'hum' (used in the sense of 'companion') and 'dard' (meaning 'pain'). 'Hamdard' thus means 'a companion in pain' and 'sympathizer in suffering'.
The goals of Hamdard were lofty; easing the suffering of the sick with healing herbs. With a simple tenet that no one has ever become poor by giving, Hakeem Abdul Majeed let the whole world find compassion in him.
They had always maintained that working in old, traditional ways would not be entirely fruitful. A broader outlook was essential for a continued and meaningful existence. their effective team at Hamdard helped the system gain its pride of place and thus they made an entry into an expansive world of discovery and research.
Hamdard Laboratories was founded in 1906 in Delhi by Hakeem Hafiz Abdul Majeed and Ansarullah Tabani, a Unani practitioner. The name Hamdard means "companion in suffering" in Urdu language.(itself borrowed from Persian) Hakim Hafiz Abdul Majeed was born in Pilibhit City UP, India in 1883 to Sheikh Rahim Bakhsh. He is said to have learnt the complete Quran Sharif by heart. He also studied the origin of Urdu and Persian languages. Subsequently, he acquired the highest degree in the unani system of medicine.
Hakim Hafiz Abdul Majeed got in touch with Hakim Zamal Khan, who had a keen interest in herbs and was famous for identifying medicinal plants. Having consulted with his wife, Abdul Majeed set up a herbal shop at Hauz Qazi in Delhi in 1906 and started to produce herbal medicine there. In 1920 the small herbal shop turned into a full-fledged production house.
Hamdard Foundation was created in 1964 to disburse the profits of the company to promote the interests of the society. All the profits of the company go to the foundation.
After Abdul Majeed's death, his son Hakeem Abdul Hameed took over the administration of Hamdard Laboratories at the age of fourteen.
Even with humble beginnings, the goals of Hamdard were lofty; easing the suffering of the sick with healing herbs. With a simple tenet that no one has ever become poor by giving, Hakeem Abdul Majeed let the whole world find compassion in him. Unfortunately, he passed away quite early but his wife, Rabia Begum, with the support of her son, Hakeem Abdul Hameed, not only kept the institution in existence but also expanded it. As he grew up, Hakeem Abdul Hameed took on all responsibilities. After helping with his younger brother's upbringing and education, he included him in running the institution. Both brothers Hakeem Abdul Hameed and Hakim Mohammed

4. Findings/ Presentation of Data:
The researchers found out in Activity 1 that matter - classified into solid, liquid
and gas – have different properties. A solid has a definite shape and fixed volume. A
liquid follows the shape of its container, has a free surface and has a fixed volume. A gas
follows the shape of the container and its volume is defined by the container.
Furthermore, the researchers found in Activity 2 that matter is a composition of
atoms better known as compounds. The manner in which they are structured is there
chemical bond. The four types of chemical bond are Ionic, covalent, polar and hydrogen
bond.
IONIC BOND. This chemical bond involves a transfer of an electron, so one atom
gains an electron while one atom loses an electron. One of the resulting ions carries a
negative charge (anion), and the other ion carries a positive charge (cation). Because
opposite charges attract, the atoms bond together to form a molecule.
Covalent bond. The most common bond in organic molecules, a covalent bond
involves the sharing of electrons between two atoms. The pair of shared electrons forms
a new orbit that extends around the nuclei of both atoms, producing a molecule. There
are two secondary types of covalent bonds that are relevant to biology — polar bonds
and hydrogen bonds.
Polar bond. Two atoms connected by a covalent bond may exert different
attractions for the electrons in the bond, producing an unevenly distributed charge. The
result is known as a polar bond, an intermediate case between ionic and covalent
bonding, with one end of the molecule slightly negatively charged and the other end
slightly positively charged.
These slight imbalances in charge distribution are indicated in the figure by lowercase
delta symbols with a charge superscript (+ or –). Although the resulting molecule is
O3) Picture 4: Methane (CH4)
5. neutral, at close distances the uneven charge distribution can be important. Water is an
example of a polar molecule; the oxygen end has a slight positive charge whereas the
hydrogen ends are slightly negative. Polarity explains why some substances dissolve
readily in water and others do not.
Hydrogen bond. Because they’re polarized, two adjacent H2O (water) molecules
can form a linkage known as a hydrogen bond, where the (electronegative) hydrogen
atom of one H2O molecule is electrostatically attracted to the (electropositive) oxygen
atom of an adjacent water molecule.
Consequently, molecules of water join together transiently in a hydrogen-bonded
lattice. Hydrogen bonds have only about 1/20 the strength of a covalent bond, yet even
this force is sufficient to affect the structure of water, producing many of its unique
properties, such as high surface tension, specific heat, and heat of vaporization.
Hydrogen bonds are important in many life processes, such as in replication and
defining the shape of DNA molecules.
Conclusion:
Generalization/ Recommendation:
Generally, matter can be classified into states – solid, liquid, gas or plasma. These
states of matter have distinguishing physical properties from each other. In addition,
matter is structured in a chemical bond referred to as ionic, covalent, polar or hydrogen.
Usually, the bond is a result of shared electrons from different atoms; thus forming a
compound.
We recommend that discoveries involving matter must be introduced or studied
such that the community is benefitted in these discoveries.
