Title III Technology Literacy Challenge Grant

Learning Experience

LEARNING CONTEXT

Purpose or Focus of Experience

The purpose of this learning experience is to provide students with an opportunity to develop a presentation that will demonstrate their understanding of cellular division and Power Point ®. The students will use Power Point ® to construct an animation of mitosis.

Connection to Standards

Standard 4: Intermediate Level Science- Living Environment

Key Idea 1:

1.1a Living things are composed of cells. Cells provide the structure and carry on the major function to sustain lie. Cells are usually microscopic in size.

1.1b The way in which cells function is similar in all living things. Cells grow and divide, thereby producing more cells. This requires that they take in nutrients, which they use to provide energy for the work that cells do and to make the materials that a cell or an organism needs

1.1c Most cells have cell membranes, genetic material, and cytoplasm. Some cells have a cell wall and/or chloroplasts.

1.1d Some organisms are single cells; others, including humans are multicellular

Key Idea 2:

2.1a Hereditary information is contained in genes, composed of a molecule known as DNA and located in the chromosome of cells.

2.1b. Each gene carries a single unit of information. A single inherited trait of an individual can be determined by one pair or by many pairs of genes. A human cell contains many thousands of different genes.

Key Idea 4:

4.4a In multicellular organisms, cell division is responsible for growth, maintenance, and repair.

Essential Question

What are the four stages of mitosis? What occurs during each one?

In what type of cells does mitosis occur?

How did the use of computers impact your understanding of the overall cellular process?

Content Knowledge

INSTRUCTIONAL/ENVIRONMENTAL MODIFICATIONS

TIME REQUIRED

Day 1: Discussion on mitosis

Day 2: Internet search and storyboard planning

Day 3 –5: Work days on presentations

Day 6: Presentations of student work

STUDENT WORK

REFLECTION

This learning experience is an activity that allows visual learning and active learning to occur. It is difficult for a student that has successfully completed the project not to gain an understanding of the cellular division. Not only is technology utilized but a microscopic cell process can come to life. Allow time to review with students the use of Power Point ® for those that need the extra reinforcement.
