Our first unit in science is ecosystems. Students will explore the complexity of the world around them and about the relationships between the living and nonliving elements in their environment. In this unit, students will create a model ecosystem by connecting a terrarium and aquarium which will contain both living and non-living elements. Students will be expected to care for the ecosystems, observe changes in the environments, and prepare for pollution experiments to determine the effects of pollutants on organisms in general in an ecosystem. This is an exciting unit for students since they will be working hands on with living creatures in their ecosystems.
Mixtures and Solutions
Chemistry is the study of structure of matter and the changes or transformations that take place in it. Learning about the make up of substances gives us knowledge about how things go together and how they are taken apart. Learning about changes in substances is important for several reasons: changes can produce new materials; changes can be used to give off energy to run machines. In our new unit, students will be introduced to these fundamental ideas in chemistry. Students will learn the concepts of mixtures and solutions, concentration and saturation, and chemical reactions. This will be a fun and "EXPLODING" unit for the students to explore!
Motion and Design
In this unit, students explore concepts related to the physics of motion and apply those concepts to technological design. Students learn that a force is any push or pull on an object, and that an unbalanced force is needed to make an object start to move, stop or change direction. They explore forces that oppose motion, such as friction and air resistance. They investigate energy using the simplest of devices- a rubber band. They discover that the energy stored in a twisted rubber band can turn an axle or spin a propeller to make a vehicle move. The students' design challenges become more complex as the unit progresses.
