    We had a very positive experience with Alissa as a tutor for our pod of 5th grade boys from January - June 2020. She cared a lot about the boys and worked hard to create meaningful activities for them. The pod experience was invaluable … More for all of our families during a difficult year and we were so grateful to have found this partnership! We also want to appreciate Craig for helping to match us with a tutor on very short notice after we had cycled through a few folks who were not able to see the commitment through. Thanks for sticking with us!

    Dusty was the exact person we needed to help our child finish out the school year. So grateful to him for the way he steadily encouraged her and helped her stay on track and organized. He is flexible, responsive to our needs/schedule as … More a family, and a delight to be with. We are also thankful that Craig at Themba Tutors really "gets it" and partnered us with such a wonderful tutor who was a great fit for our girl.

    My child worked with Gillian D virtually for math enrichment. She is an excellent teacher. She took time to understand my child's specific learning style and provided tools that would be engaging. She was kind and empathetic- really … More made it her goal to connect with my child and build trust and rapport. My child started the school year with confidence and without the typically "brain-drain" that occurs over the summer, thanks to Gillian.

    I am going into my second year as a Themba tutor. I have met so many great individuals while working for this company. Craig and the rest of the Themba team do such an excellent job picking and choosing Themba tutors that suit each client's … More individual needs! I look forward to meeting new tutors and clients in the 2021-2022 school year!
  • Avatar carolina luttmann ★★★★★ 11 months ago
    Our son started in a new high school, 100% remote, and was really struggling with Latin and Physics. I found Themba Tudors online and had an initial call with Craig, who was very knowledgeable, responsive, and found 2 amazing tutors for … More us. Both the Latin and the physics tutors were fantastic, connected with my son really well and helped him go from 'failing' grade to 'honors'! I will for sure continue using (and recommending!) Themba Tutors. Thank you, C, K, and W!

  • Avatar Susan Wong ★★★★★ a year ago
    Giulia Mercuri is a great Italian tutor! She was very responsive and accessible. Giulia put a ton of effort into preparing for each session and really helped our son with test preparation and projects. We are grateful that she was able … More to help, especially since our son did not receive any live teaching during COVID. We are happy that she was referred to us!
  • Avatar Christine Gennetti ★★★★★ a year ago
    As an adult student diagnosed with a learning disability during grad school, I knew I needed help dealing with my Master's program's demanding workload. I was seriously considering dropping out when I was referred to Themba Tutors. … More I was paired up with a wonderful tutor, Julie, who was a total lifesaver. I learned many techniques that I can utilize in the future as I embark on the next phase of my career.
    I can wholeheartedly say after working with Themba for two years that I would not have finished my program without this organization. And I am so thankful I selected them.

    We were introduced to a wonderful tutor: Mcedwyn. He and our son, a freshman in college, worked well together. As a result, our son’s grades significantly improved. The tutor taught our son subject content and various methods to effectively … More study for quizzes and exams. Our son was also taught time management and organization. My son’s experience with the tutor made the first year of college a less intimidating experience.
  • Avatar Jude Eugene ★★★★★ a year ago
    We have been with our tutor, Cailin Schiller, for two years, from 5th - 7th grade. She started as an executive functioning tutor with my daughter. From the start, she demonstrated a depth of expertise and a selective use of techniques skillfully … More adapted to my daughter’s ADHD and Math disability. Cailin made Math accessible and understandable to her in a way that even her teachers had not been able to do. She differentiated reading, writing and math tasks and assignments to tailor them to my daughter’s unique learning differences. Not only did it have an effect on her grades and her work efficiency, but she finally could do her work with less anxiety. Even my daughter’s teachers used Cailin’s guidance to modify their work with her. But most importantly, she became my daughter’s favorite resource. I can’t say how invaluable Cailin has been to my daughter’s progress and well-being. I’d recommend her a million times over. She is a gem.

    I'm so glad we were referred to Themba Tutors. After a great initial conversation to learn our needs, we were connected with an excellent tutor, Felicia, who is helping our high school daughter learn better organizational and executive … More skills. Highly recommended.

    Themba Tutors provided a leaning specialist that was a perfect fit for my daughter. I told them what we were looking for and they delivered. Our tutor is responsive and flexible and makes it easy for my daughter to reach out to her own … More her own, which gives her an added sense of responsibility over her learning. As a therapist myself, I now regularly recommend Themba to my patients. A much needed and well provided service to the community!!
  • Avatar Frances Simpson ★★★★★ 3 years ago
    The tutors at Themba are fantastic! Caitlyn McNeill helped our son academically, but also with getting organized in every subject, which he so desperately needed. She offered great advice and useful strategies that helped our son become … More a more successful student. We are using Themba tutors again this year for our daughter. We're so happy to have been referred to them!

    Paul Smith at Themba has been an exceptional tutor for my son, both in terms of teaching the subject matter and teaching how best to approach the process of learning math and executing assignments. We feel very fortunate to be working with … More Paul.

    We were very lucky to have found Edwouine Swift, my son's therapist through Themba Tutors. Thomas is 12 years old, and it is extremely difficult to get him to write. Edwouine just works her magic with him, he adores her and is so … More eager to follow her guidance. I have no doubt she will be a positive driving force in his academic future.

What Is Chemistry?

 

Chemistry is the science that studies matter. It involves elements and compounds composed of atoms, molecules, and ions: their composition, structure, properties, behavior, and the changes they undergo during a reaction with other substances.

 

Chemistry is involved in everything we do.

 

  • See
  • Hear
  • Smell
  • Taste
  • Touch

THE PERIODIC TABLE: CRASH COURSE CHEMISTRY #4

Chemistry includes seeing, hearing, smelling, tasting, and touching. It involves an intricate series of chemical reactions and interactions in your body.

 

Chemistry is a big part of our everyday life. We can find chemistry in foods, in the air, substances, our emotions, and literally every object we can see or touch.

Science _ Chemistry (1)

Chemistry Basics

 

Chemistry touches everything we do because almost everything in existence can be broken down into chemical building blocks.

 

The main building blocks in chemistry are chemical elements, which are substances made from one atom. Each chemical is exclusive, composed of a group number of protons, neutrons, and electrons. It is identified by a reputation and a chemical symbol, like “C” for carbon. The elements that scientists have discovered so far are listed in the table of elements. They include both elements found in nature, such as carbon, hydrogen, and oxygen, and artificially produced elements like lawrencium.

 

Chemical elements can bond together to make chemical compounds, which are substances made from multiple elements, like CO2 (which is formed by one atom connected to two oxygen atoms), or atoms of a single element, like oxygen gas (which is made of two oxygen atoms connected). These chemical compounds can then bond with other compounds or elements to make countless other substances and materials.

What Are the Five Main Branches of Chemistry?

Analytical Chemistry

 

Analytical chemistry studies the composition and structure of matter and chemicals. It includes obtaining, processing, and communicating information to determine what matter is and how much of it exists.

 

Biochemistry

 

Biochemistry uses chemistry techniques to understand how biological systems work at a chemical level. Thanks to biochemistry, researchers are ready to map the human genome, understand what different proteins neutralize the body, and develop cures for several diseases.

Science _ Chemistry

Inorganic Chemistry

 

Inorganic chemistry studies the chemical compounds in inorganic or non-living things like minerals and metals. Traditionally, inorganic chemistry considers compounds that do not contain carbon (covered by organic chemistry), but this definition is not completely accurate, according to the American Chemical Society (ACS).

 

Some compounds studied in chemistry, like “organometallic compounds,” contain metals that are attached to carbon — the most studied element in chemistry. As such, compounds like these are considered a part of both fields. Inorganic chemistry is employed to make a variety of everyday products, including paints, fertilizers, and sunscreens.

 

Organic Chemistry

 

Organic chemistry deals with chemical compounds that contain carbon, a component considered essential to life. Organic chemists study the composition, structure, properties, and reactions of such compounds, which along with carbon, contain other non-carbon elements such as hydrogen, sulfur, and silicon. Organic chemistry is employed in many applications, as described by the ACS, like biotechnology, the petroleum industry, pharmaceuticals, and plastics.

 

Physical Chemistry

 

Physical chemistry uses concepts from physics and apply them in the context of chemistry. For example, deciding how atoms move and interact with one another or why some liquids, including water, become vapor at high temperatures. Physical chemists attempt to understand these phenomena at a really small scale — on the extent of atoms and molecules — to derive conclusions about how chemical reactions work and the things that give specific materials their own unique properties.

Here are some helpful lecture videos with hands-on, interactive problem solving for all levels of science for ages 10 and up to master essential skills.

What Do Chemists Do?

 

Chemists work in a variety of industries and fields of work. Most chemistry graduates typically choose a branch of chemistry to specialize in, whether it’s biochemistry, analytical chemistry, or neurochemistry.

 
Chemists in the pharmaceutical industry are key in developing drugs and studying their properties. You can also find chemistry graduates working as chemical engineers, forensic scientists, and geochemists, to name a few.

 

Why Is Chemistry Important?

 

As one of the core fields of study in science, studying and mastering chemistry is crucial because it helps us understand the world around us. Everything in our daily lives involves chemistry and chemical reactions, including the processes within our bodies. From breathing, eating, or just sitting to watch your favorite TV show. Even the emotions we go through in everyday situations involve chemical reactions.
 
Chemistry is defined as the study of matter, which composes everything that we see or touch. This includes things that are essential to our daily lives, like food. By studying matter, chemistry helps us determine how they interact with each other, how electromagnetism and other factors affect them, and how they respond to energy.
