Overview

Everything is chemistry, and teaching it is enjoyable in that students gain an intricate perspective on how we interpret our world and universe, in terms of matter and energy and their transformations. Biology on the other hand adds a systemic approach to how atoms combine and breathe life into the chemical arrangement. Students begin to ask questions that we as scientists and as a humanity have not quite figured out. The goal of this unit is to integrate student understanding of Biology, Chemistry and Cosmology. Students will appreciate the similarities and differences in the behavior of matter and energy, and how they affect the living and non-living in the universe.

The most pleasurable part of teaching chemistry is when students connect science concepts to experiences in everyday living. As they apply the conceptual understanding to different situations, they are provoked to ask different questions in the interplay of so many variables. As scientists, they begin to appreciate that we investigate and analyze consistent results within a specified, limited set of conditions. However, many variables beyond those mentioned in this curriculum ultimately affect outcomes in the natural world.

This unit seeks to engage students to initially deepen and extend their understanding of earth and the variety of environments, and then reconcile the variety of living organisms that thrive in some of these extreme conditions. Students will compare these conditions to planets in our universe to create the existence of an “alien” using a scientifically plausible argument.

 

Rationale

I structured this unit such that every subsequent topic builds on previous learning. It also reminds 11th grade chemistry students of the biology course taken in their prior year as 10th graders. Students can gain an appreciation of the integration of science disciplines from the systemic to the atomic and then enlarge and connect their years of science learning, into the discipline of cosmology. Students take on an online investigative approach, developing a series of inquiry experiences as digital natives. They develop competence and confidence as they develop domain specific language as scientists when

they navigate through information and then write, speak, listen, collaborate and express their understandings with the culmination of their final task, to create a fictional alien.

In pedagogy, both Piaget and Vygotsky contributed to our current understanding of cognitive development in a child. However, it was Vygotsky’s theory that stressed the importance of cultural language on one’s cognitive development. My students struggle to access scientific vocabulary to express their understanding. Repeated dialogue with their peer groups and during presentations will support strengthening the use of content specific vocabulary. The topics present opportunities for students to explain the meaning and then explain the concepts. They will learn how to research and shape the information they gather as they collaborate with their peers, with teacher facilitation.

The technology-supported Jigsaw approach is a student centered learning technique that provides a climate that enables inclusive, flexible, and unique learning for growth according to student interests, with the development of multiple levels of complexity. The environment fosters depth and expanded understanding with peer collaboration and teacher facilitated reflection, fostering enriched thinking and learning. According to Schon, 1983, learning is a dynamic process of “reflection-in-action” where action is used to extend thinking, and reflection is governed by the results of action.

In chemistry, students know the Periodic Table as the alphabet of atomic structure. The curriculum predominantly focuses on chemical interactions; nuclear chemistry may be an optional addition. In biology, students are already familiar with the characteristics and classification of life forms, so this unit section would serve as an extension to expand their thinking. The goal is to spark student curiosity into the infinitesimal realm of the universe.

Initially the unit starts with a reminder lesson by students in 10th grade that have completed their Keystone State Tests in Biology. The students will share their understanding of the how we define life. A sample of topics that are questioned follows:

• How do we know something is alive?

• How does life result from chemical structure and function?

• How cellular structure and function affect life?

• How do organisms interact and depend on each other and their environment for survival?

• How do different organisms obtain and use energy to survive in their environment?

At this point 10th grade students reflect on the depth of their understanding, as they present and share their year’s learning with their 11th grade school community.

After the 11th grade students have had an opportunity to remind themselves of the characteristics that define life, they will carry out their own investigatory experience on the types of extremophiles that exist on earth. Extremophiles are fascinating, not only will students gain an understanding of the extreme environments in which the organisms thrive, but also the anatomical and physiological traits that enable them to do so. Students will also find through their investigation that scientists study these characteristics as a means to find solutions to problems that humankind encounters.

Some of the intrigue would be for students to raise their own questions as they investigate the different types of extremophiles such as:

• What is life?

• What are the limits of life?

• What are the fundamental features of life?

Students will explore how organisms can thrive in environments that have

water at temperatures that are below freezing or are boiling, chemical extremes with pH <5 or >9 and conditions of salinity that are ten times that of water.

As students digest the vastness of organisms and environments on earth they will then continue their investigations on the possibility of the existence of life on other planets. In order to do this, they will need to understand and compare the conditions on earth with that available on other planets. Here students will explore the following questions:

– What are the possible characteristics of our nearest planetary neighbors?

– What would an experience of “a day” be on that planet?

– What form and lifestyle can be constructed based on the environment and the characteristics that enable the life of an organism?

In this section students will gain an understanding of the Terrestrial and Jovian planets, the Kuiper Belt, characteristics of the planets with their moons, the composition of meteorites, asteroids and comets, water in space and volcanism in space. Moreover, they will consider the Drake Equation used to estimate possible advanced civilizations in the Galaxy with radio transmission, and raise questions related to communication. Should student interest emerge in alien communication, it may be an opportunity towards watching and discussing the movie, The Arrival. The intervention would promote deeper discussions.

 

Objectives

This unit is intended for high school students in an urban setting. My students are diverse in how they engage with learning through narrative, conceptual and mathematical ideas.

Furthermore, my students are preoccupied with preparing for college admission. As they navigate and negotiate through the day, students are embedded in a digital, social, cultural environment in which communications are rapid and real-time. The same approach is used to respond to questioning through rapid research using digital media. Scanning and skimming through information predominates and the result is that compromises are made in the processes of reflection and creation. This unit attempts to explore that active learning space using structured development of student questioning, collaboration and contemplation.

This unit can be divided into four major themes. I want my 10th grade students to culminate their year’s learning and share their expressions with my 11th grade students, this is also a time to reflect on the ideas that Biology brings to their perception of how we define life. On the receiving end of the teach-back that the 10th grade students have created, I want my 11th grade students to reflect on their course in Biology, a year later having grown through the lens of the chemistry course. Students from the 11th grade can take time to fuse their ideas on the characteristics that define life, through the lens of the elements of the periodic table, and the multitude of transformations of matter and energy.

It is through the reconciliation of the biology and chemistry courses that I hope my students will further develop an understanding of the extreme conditions that are here on earth, and how extremophiles exist using specialized anatomical and physiological attributes to co-exist in these environments. I trust it will provoke further questioning by students regarding the factors that promote and limit life – as we know it.

As students continue through the unit, they will develop an understanding of Cosmology and the different environments on different planets. Students will question and respond to the forces that affect each planet and the variety of celestial bodies that impact each planet. I want them to grasp the idea that everything in the universe is connected. What may appear as a random incident, bears connections to a series of incidences.

Finally, to apply what they have learned, students will create an alien that appears as a scientifically plausible organism. My students enjoy science fiction movies. In this final role, they become masters of creating their own species providing plausible scientific arguments to support their creation – of an alien.

 

Strategies

The major strategies implemented in this unit use the following learning progressions:

Activating prior knowledge in biology by reviewing the characteristics of life and the cell structures of living organisms. Followed by how organisms interact with their

environment to survive and thrive. The objective is achieved by the use of the Jigsaw Method developed by Elliot Aronson in 1971. It is a cooperative learning strategy where each student in a group takes responsibility for one chunk of the content, then teaches it to the other group members. Similar to a jigsaw puzzle, students fit their individual chunks together to form a complete body of knowledge. The Jigsaw Strategy is used in the activities on the first and second days to activate prior knowledge from the previous year. The topics are divided into content chunks and each group of students are assigned a topic chunk and are the the subject matter experts on the topic.

In the classroom students are divided into groups of 2-4 students to a group. Although the Jigsaw works best when there are an equal number of students in each group, it is necessary at times to modify and accommodate the arrangement for students who prefer to work on their own. However, care needs to be taken so that all the content is distributed amongst the students, and sections are not omitted.

The Jigsaw strategy is used not only to activate prior knowledge and meet the objectives at the start of the unit. It is also used to extend knowledge on the 3rd and 6th

day activities. On the third day each student group investigates a category of extremophiles, and on the sixth day each student group investigates and compares the environmental conditions of a planet with that on earth. According to Marzano (2007) the strategy of comparison improves comprehension by highlighting important details, making abstract ideas more concrete, and reducing the confusion between related concepts.

There is a substantial amount of information that students will be assimilating and integrating, to meet the final objective of creating and then presenting a scientifically plausible alien on the 7th and 8th activity days for this unit. In their years of research into the defining characteristics of intelligent behavior and thought, Art Costa and Bena Kallick (2008, 2009) have identified 16 “habits of mind.” By nourishing these habits in our students, we give them sustainable study tools they need to use their minds well, thus increasing their chance for future success. Using the Compare & Contrast Strategy with the environmental conditions on earth with their assigned group planet and using the Jigsaw Method – combined, the approaches will help students develop these habits of mind: thinking flexibly; thinking about thinking (metacognition); striving for accuracy; applying past knowledge to new situations; and thinking and communicating with clarity and precision.

Finally, students will be practicing a variety of techniques to explain and detail their learning such as Think-Pair-Share and Presentations employing a variety of topics throughout this unit. These strategies in blended with the Jig-Saw Strategy enables students to integrate the disciplines of Biology, Chemistry and Cosmology with depth and breadth, effectively managing time to collate scientifically detailed arguments to support the existence of their created alien.

 

Activities

In light of the numerous possibilities, a foundational core structure for this introductory unit is prepared for 10th and 11th grade students with 55- minute classes. The unit may be adapted for middle school students.

11th Grade Chemistry students take notes as a reminder of the characteristics from the course taken in the previous year, and as a stacked scaffold towards the investigation into life beyond earth.

Activity Day 3

11th Grade Chemistry students are divided into groups to examine the categories of Extremophiles that exist on earth. Student Groups of 3-4, each investigate the environmental conditions and the living organisms that inhabit the environment. Students will then detail the specific conditions and, the necessary anatomical and physiological features, that enable extremophiles to thrive in their given environment. Each student group will create a Blog explaining the global locations where the extremophiles are found, with current updated information.

The group topics are:

1/ Psychrophiles

Thrive in low temperatures below 15 Deg. C and as low as -20 Deg. C

2/ Thermophiles

Thrive at high temperatures of 40 °C or higher

3/ Radio resistant Microbes

11/ Space Travel Survivor

Tardigrades are currently the most recognized space survivor to date and has survived:

– Temperature ranges from zero to 150oC

– Survived space conditions resistant to radiation and pressure 2007

– Capable of losing 99% of water mass through cryptobiosis and reanimate after 10 years of desiccation.

– Macromolecule, tehalose presence in cells prevents damage from desiccation

Activity Day 4 & 5

Students share their learning with peers on the different organisms existing in each designated extreme condition. Each presenting group has 10 minutes to share the information: 7 minutes for the presentation and 3 minutes for questions and answers.

Activity Day 6

Students now have an understanding of a variety of anatomical and physiological characteristics that enable them to live through extreme conditions on earth. They will now gain an understanding of the variety of atmospheric conditions that exist on planets.

The teacher will show an online presentation with information detailing the atmosphere, moons, density etc. on earth. Students are then assigned into groups each group will have

a planet to investigate. The characteristics of each planet will be compared to the atmospheric conditions on earth.

The group topics are:

Jovian Planets: Jupiter, Saturn, Uranus, Neptune

Terrestial Planets: Mercury, Venus, Mars, (Earth – Teacher)

Activity Day 7

Students work in groups of 3-4 students:

Create an extraterrestrial life form on another planet, connecting the scientific research between the organism and the environment, as if a character in a Science Fiction Movie.

Students will define

– The civilization in terms of living characteristics of the organism ecosystem, with the energy flow

– The physical and chemical needs of the organism and how the environment supports life.

– A typical “day” in the life of the organism, including length of time, seasons, threats that may exist for survival in the ecosystem.

Activity Day 8

Student groups will create a PowerPoint or Prezi presentation of their chosen planet and their Science Fiction organism. They will then construct an organism and define the environment with which it interacts to survive and perhaps thrive.

This unit focuses on a variety of scientific disciplines, and students may focus on one particular science discipline over another. Students should be prepared to defend their rationale and argument when presenting their life form and ecosystem in front of their peers. Science can be considered a practice that reconciles explanations through investigations and reflections. To learn, students will need to go through the experience of gathering pertinent information and then reapplying it to integrate and apply to create a new situation. The learning experience lends to growth and an expansive collaborative experience. Students will find at times, that gathering valid information is challenging. This is when perseverance and grit is most needed. All too often our digitally native students accustomed to a world of information at their fingertips, can easily succumb to misinformation. This unit encourages students to seek credible information, to make better decisions.

In addition, on the topic of Reflecting on the Processes of Science and Engineering, the authors of the standards state:

Engaging students in the practices of science and engineering outlined in this section is not sufficient for science literacy. It is also important for students to stand back and reflect on how these practices have contributed to their own development, and to the accumulation of scientific knowledge and engineering accomplishments over the ages. Accomplishing this is a matter for curriculum and instruction, rather than standards, so specific guidelines are not provided in this document. Nonetheless, this section would not be complete without an acknowledgment that reflection is essential if students are to become aware of themselves as competent and confident learners and doers in the realms of science and engineering.
