Jun 18, 2023 · For middle and high school students, Montessori methods continue to nurture individual learning while inspiring children to explore subjects that interest them through positive discovery. Overall, Montessori’s philosophies were significant in showcasing the “guided by children” method that celebrated learning and exploration over specific academic results in predetermined categories.
Undergraduate Program. Human Developmental and Regenerative Biology (HDRB) is a life science concentration that educates students on how human beings develop from a fertilized egg, are maintained and repaired throughout adulthood, and age till life’s end. Students will be given a broad education in modern life sciences by studying important ...
- Genetics and Heredity: Understanding Life’s Blueprint. Genetics and heredity are the foundation of life’s diversity. High school students can explore how DNA acts as life’s blueprint through simple experiments like DNA extraction from fruits or studying genetic traits and inheritance patterns.
- Microbiology: Tackling Antibiotic Resistance. Antibiotic resistance is a critical challenge in microbiology, impacting global health. Students can study this by examining how bacteria grow and respond to antibiotics, showcasing natural selection and mutation.
- Botany: The Role of Soil in Plant Growth. The type of soil is crucial for plant health and agricultural output. Students can investigate plant growth in different soils—clay, loam, sand, silt—or analyze the impact of soil pH and nutrients.
- Zoology: Understanding Local Wildlife Behavior for Conservation. Exploring research ideas in biology for high school students can begin right in their backyard by studying local wildlife behavior.

In this section, we will look at some of the ways in which heredity helps to shape the way we are. Heredity involves more than genetic information from our parents. According to evolutionary psychology, our genetic inheritance comes from the most adaptive genes of our ancestors. We will look at what happens genetically during conception and take a ...
Evolutionary psychologyfocuses on how universal patterns of behavior and cognitive processes have evolved over time. Variations in cognition and behavior would make individuals more or less successful in reproducing and passing those genes to their offspring. Evolutionary psychologists study a variety of psychological phenomena that may have evolve...
Gametes
There are two types of sex cells or gametesinvolved in reproduction: the male gametes, or sperm, and female gametes, or ova. The male gametes are produced in the testes through a process called spermatogenesis, which begins at about 12 years of age. The female gametes, which are stored in the ovaries, are present at birth but are immature. Each ovary contains about 250,000 ova but only about 400 of these will become mature eggs (Mackon & Fauser, 2000; Rome, 1998). Beginning at puberty, one ov...
Chromosomes
While other normal human cells have 46 chromosomes (or 23 pair), gametes contain 23 chromosomes. Chromosomes are long threadlike structures found in a cell nucleus that contain genetic material known as deoxyribonucleic acid (DNA). DNA is a helix-shaped molecule made up of nucleotide base pairs [adenine (A), guanine (G), cytosine (C), and thymine (T)]. In each chromosome, sequences of DNA make up genes that control or partially control a number of visible characteristics, known as traits, suc...
Genotypes and Phenotypes
When a sperm and egg fuse, their 23 chromosomes pair up and create a zygote with 23 pairs of chromosomes. Therefore, each parent contributes half the genetic information carried by the offspring; the resulting physical characteristics of the offspring (called the phenotype) are determined by the interaction of genetic material supplied by the parents (called the genotype). A person’s genotype is the genetic makeup of that individual. Phenotype,on the other hand, refers to the individual’s inh...
Chromosomal Abnormalities
A chromosomal abnormality occurs when a child inherits too many or too few chromosomes. The most common cause of chromosomal abnormalities is the age of the mother. A 20-year-old woman has a 1 in 800 chance of having a child with a common chromosomal abnormality. A woman of 44, however, has a one in 16 chance. It is believed that the problem occurs when the ovum is ripening prior to ovulation each month. As the mother ages, the ovum is more likely to suffer abnormalities at this time. Another...
Prenatal Testing
Prenatal testing consists of prenatal screening and prenatal diagnosis, which are aspects of prenatal care that focus on detecting problems with the pregnancy as early as possible. These may be anatomic and physiologic problems with the health of the zygote, embryo, or fetus, either before gestation even starts or as early in gestation as practical. Prenatal screening focuses on finding problems among a large population with affordable and noninvasive methods. The most common screening proced...
Behavioral geneticists study how individual differences arise, in the present, through the interaction of genes and the environment. When studying human behavior, behavioral geneticists often employ twin and adoption studies to research questions of interest. Twin studies compare the rates that a given behavioral trait is shared among identical and...

Human Development or Lifespan Development is the scientific study of the ways in which people change, as well as remain the same, from conception to death. You will discover that the field, known more broadly as developmental science, examines changes and stability across multiple domains of psychological and social functioning.
Developmental Tutorials are video recordings of describing key concepts in the field of Developmental Biology. These tutorials are authored by Developmental Biologists Michael Barresi and Scott Gilbert who are the co-authors of the textbook “Developmental Biology,” which is currently in its 13th Edition and published by Sinauer Associates and Oxford University Press.

In this chapter, we explore the biological bases of learning and development: the brain-based, neurobiological nature of perception, learning, and memory; how the brain changes in response to experience; how cognitive development occurs through progressive modifications in representations in the brain; and how the tools and methods of the neurosciences elucidate the mechanisms and processes of ...
