Answer:
Students will explore the structure and function of cells - the building blocks of life. Using a simple factory analogy, they will discover how the major parts of a cell work together to make a product. Each student will build a 3-D cell model to help visualize the abstract world of the microscopic cell.
Students will:
discover that in nature “form fits function”;
understand that there is order to a living thing, and that cells give rise to tissues, tissues to organs, and organs to organ systems;
identify organelles and other cellular structures by their scientific names;
learn how organelles and other structures work together in a cell; and
build a macroscopic model of an animal cell.Examine the five kingdoms of life through a microscope! Slides of animal, plant, fungi, protist, and bacteria cells are magnified up to 400x in a compound microscope as part of an exploration of biodiversity and classification.
Students will:
view cells from all five kingdoms magnified through a compound microscope;
record microscope observations;
compare and contrast cell types; and
learn how to prepare a wet mount slide with cheek cells and use a compound microscope.Understanding the structure of DNA helps to explain its function. In this lab, students are introduced to the composition of DNA building blocks called nucleotides. They will discover how the subunits of the nucleotides - nitrogenous bases, phosphate groups and deoxyribose sugars - fit together to form the double helix. The lab concludes with the construction of 3-D models that show the famous structure.
Students will:
discuss the role of DNA in living things;
explore the structure and function of the DNA molecule;
learn about the base pairs of DNA and the importance of sequence; and
construct a model of DNA.Gregor Mendel is known as the “Father of Genetics.” His proposed principles of heredity—based on his own observations of heredity in garden plants—formed the basis of our understanding of classical genetics. In this lab, kernel color in corn is used to illustrate some of Mendel’s laws of inheritance.
Students will:
collect data from corn crosses to show patterns of heredity;
use Punnett squares to predict possible outcomes from genetic crosses; and
learn how Mendel’s laws can be applied today.
