CURRICULUM PLANNING AND RESOURCE PACKAGE

Water Systems on

Earth

Scope The Grade 8 Unit of Water Systems on Earth covers a

variety of topics about water. Outcome WS8.1, has students exploring the distribution of

water, the water cycle, and human interactions and influences on water systems

Outcome WS8.2, includes understanding water ‘s effect on the landscape and environment.

Outcome WS8.3 focuses on water wildlife species and how water and the changing environment effects them.

There is also a significant focus in our unit on sustainability and conservation of water that is reflected throughout the outcomes and is highlighted in many of the activities and discussions. This is important because students are learning about water, but also changing their perspective to positively influence the future of our planet.

Sequence and Timeframe This unit follows the same sequence as

the curriculum, starting with Outcome WS8.1, then WS8.2, and finally WS8.3. The unit focus on sustainability of water and it ties in with both starting and ending the unit.

The unit covers an estimated time of 6 – 8 weeks, depending on how much time is spent on some of the activities and extension opportunities.

Pedagogical Strategies This unit is made up of a majority of activity based

learning. We chose this approach because it provides the opportunity for students to experience the learning and have hands on experience in the science field. This allows for a deeper understanding of the topics and learning. We experimented with non traditional ways of teaching science in order to get students excited and interested. We also incorporated activities and techniques that adapted to all types of learners, visual, audio, and kinaesthetic, so all students have the chance to learn and enjoy. Human and environmental justice was another approach we had during this unit. The human element is brought in to work with the indicators, but also provide the unique opportunity for students to think more critically about the world and how we can improve it.

‘5 E’ Learning Cycle The ‘5 E’ learning cycle is important to

our unit and is incorporated in many ways. Since out unit is comprised of activities, we have a unique opportunity to utilize this cycle a lot. In some cases, the 5 ‘E’s are all used in a single activity and other times there is a combination of activities that work together to piece the 5 E cycle for the student’s benefit.

Classroom Management and Safety

At the beginning of the Water Systems Unit it is important to establish classroom rules and expectations. Within these expectations we will also establish classroom safety rules and procedures. Throughout the unit we will review to ensure that all students understand. Our classroom management strategies will be activity based. By making our classroom activity based it will keep the students engaged and interested. This responsibility will empower students to achieve their goals. Our activities that we chose to engage students also involve different environments to keep students interest by not always being in the classroom. To help with time management in the classroom pre made groups will be made at the beginning of the unit to maximize time for activities.
