Students use model chromosomes and answer analysis and discussion questions to learn about meiosis and fertilization. As they model meiosis and fertilization, students follow the alleles of a human gene from the parents' body cells through gametes to zygotes; thus, students learn how a person inherits one copy of each gene from each of his/her parents. To learn how meiosis contributes to genetic variation, students analyze the results of crossing over and independent assortment. Students also compare and contrast meiosis and mitosis, and they learn how a mistake in meiosis can result in Down syndrome or death of an embryo. This activity helps students meet the Next Generation Science Standards.

Overview:  I created this activity to provide my students with a fun way to learn about the parts of the flower. The student will investigate and understand basic plant anatomy and life processes.  NOTE: The word “pistol” is used in the story in reference to the female part of the flower (pistil).   Key concepts include:a) the structures of typical plants and the function of each structure;b) processes and structures involved with plant reproduction.

Join Joe as he takes us on a fun investigation into the life of plants. Learn about the types of plants, and how plants survive in their environment. Explore vascular and non-vascular plants through an experiment using the scientific method—and celery! Learn about photosynthesis and dormancy and dive into the parts of plants and pollination. Plants are so important to our lives. Let's get to know them better!
