Description

Engage your students with this week-long STEM challenge.

The Challenge:

Since the 1700s, scientists have identified organisms using a choice-based system called a dichotomous key. The key uses a series of questions with two options at each step. Answering each question brings you closer to identifying your species. First, you will research dichotomous keys to begin understanding how they function. Next, you will create your own dichotomous key. You will be given a group of unique buttons that each represent an organism from a different species. You will first need to name each of your organisms, then build a dichotomous key based on their characteristics. Finally, you will exchange your key and buttons with another group to see if they can identify each of your organisms. You will do the same with theirs. Good luck!

What's Included

• The 21st-century problem includes a video challenge which outlines the activity in a fun and easy to understand way.

• The slideshow presentation (PPT) allows the teacher to facilitate the pacing throughout the project.

• The teacher lesson plans include TEKS and NGSS standards alignment, and step-by-step directions on what the teacher and students should be doing along the way.

• The student notebook will guide the student through the activity. The questions will challenge students to learn new information, reflect on learned information, and provide the students a framework for the entire project.

• Each lesson is written using the Launch process. Students are going to be brainstorming with their peers and reflecting on failures and opportunities. At the end of each project, we’ve asked the students to share their ideas with the world. This holds students accountable. They will put forth the best effort knowing other students could critique the project.

What Supplies Do I Need

Each product contains a list of suggested supplies for the project. We were very cautious about choosing inexpensive items. This project has a suggested supply list that includes:

A large variety of buttons (natural items can be used as well)

The supply list is dynamic and can be adjusted to your situation.

NGSS and TEKS Standards

Supports Next Generation Science Standards:

MS-ETS1-1

Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions.

MS-ETS1-2

Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

MS-ETS1-3

Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

MS-ETS1-4

Develop a model to generate data for iterative testing and modification of a proposed object, tool, or process such that an optimal design can be achieved.

Texas TEKS:

7.11A

Examine organisms or their structures such as insects or leaves and use dichotomous keys for identification.
