Preface IMAX Program partners with schools, supporting them with learning materials and processes that are all crafted to work together as an interconnected system to drive learning. IMAX Program presents the latest version of the Pinnacle series – specially crafted as an accompanying workbook series for the Tamil Nadu state board textbooks. The Pinnacle series endeavours to be faithful to the spirit of the Tamil Nadu Curriculum Framework in conjunction with the content covered and approach adopted in the Samacheer textbooks. The Class 5 workbooks are based on the latest edition of the Class 5 textbooks released for the academic year 2020 -21. A close mapping has been undertaken to ensure that the workbooks support and add value to the textbook content. The larger aim of the TNCF 2017 regarding EVS/Science teaching is to acknowledge and address the dynamic nature of EVS/Science by focusing on the development of skills to acquire and process information scientifically. It also recommends the use of graphics, illustrations and pictures to help students to engage with concepts and ideas better. Below are some salient features of the Pinnacle EVS/Science workbook series:  Arrangement of questions based on the RUAH (Remember, Understand, Apply and Higher Order Thinking Skills) model based on Bloom’s Taxonomy  Stimulating Application and Higher Order Thinking Skills (H.O.T.S.) questions that ensure students engage with the content and not just focus on rote learning  Effective use of concept maps to enable learning of structures, processes and phenomena  Exposure to locally relevant environmental problem solving Overall, the IMAX Pinnacle series aims to enhance the development of scientific temper along with the inculcation of healthy habits, skills and values that promote environmentally sensitive and culturally responsive democratic citizenship among students. – The Authors PNC_Science_G5_WB_Term1.indb 2 3/13/2020 7:19:47 PM

Inside the Lab Up, Up and Away! Every object on the Earth has potential energy at rest. When an object is moving, it has kinetic energy. A catapult helps in energy conservation. Let us make a catapult and find out how a catapult helps to transfer energy from the spoon to the object. The object will have potential energy until the spoon is released. Then, the object will have kinetic energy as it flies through the air. You will need: nine craft sticks or ice-cream sticks, six good-quality rubber bands, one plastic spoon. You need to: 1) take seven craft sticks and bind them together using two rubber bands, one at each end. 2) bind the other two craft sticks together towards the end of the sticks, using another rubber band. 3) put the stack of seven sticks in between the two-stick bundle. 4) secure these two bundles with a rubber band in a cross fashion. 5) use a few rubber bands and attach the plastic spoon to the open end of the top stick, as shown in the given image. 6) try catapulting pebbles or other small objects using the catapult. Explain how energy is converted when you use the catapult you prepared.
