14. 14. Foreword This Teacher’s Instructional Presentation Hand-out entitled “ Enjoy Learning With Science ” is part of the requirements in Educational Technology 2 under the revised curriculum for Bachelor in Secondary Education based on CHED Memorandum Order (CMO)-30, Series of 2004. Educational Technology 2 is a three (3)-unit course designed to introduce both traditional and innovative technologies to facilitate and foster meaningful and effective learning where students are expected to demonstrate a sound understanding of the nature, application and production of the various types of educational technologies. The students are provided with guidance and assistance of selected faculty members of the College through the selection, production and utilization of appropriate technology tools in developing technology-based teacher support materials. Through the role and functions of computers especially the Internet, the student researchers and the advisers are able to design and develop various types of alternative delivery systems. These kind of activities offer a remarkable learning experience for the education students as future mentors especially in the preparation of instructional materials. Contents Back Next

Like solid become liquid and liquids became solid. There are two changes of Matter the Physical Change and Chemical Change. Physical Change it is change in appearance, shape or form of matterbut the composition or the content of matter is still the same. One example is melting of ice. The content of this matter is still no changes. Contents Back Next
25. 25. Chemical Change is a change not only in the size appearance,and shape but also in their content and properties. One of the example is burning of wood when the wood is burned it lost their physical appearance and a new characteristic formed – because the wood became ashes and the properties and content of the matter change. Remember this kid!!! Physical change is changes in appearance, shape, or form but not in composition Chemical change is change in appearance shape,form and also in composition Did you understand the lesson clearly?

A spring scale measure force but not mass, a balance compares masses, but require a gravitational field to operate. The most accurate instrument for measuring weight or mass is the digital scale, but it also requires a gravitational field, and would not work in free fall. Measuring Mass: To measure a mass we need a balanced; this kind of device helps us to measure mass. Mass is the amount of matter in a body. The relationship between gram and kilogram is expressed as: Contents Back Next
30. 30. Balance use to measure mass. 1,000 grams (g)= 1 kilogram (kg ) How to measure Volume: Volume is the amount of space that an object occupies An instrument use to measure volume is a graduated cylinder To measure the small volume of liquid you can use medicine dropper or teaspoon. Is use? Liter (L) and milliliter (mL.) are the common units of volume The relationship between Liter and milliliter is shown as: 1,000 mL = 1L 5 mL. = 1 teaspoon 1 mL = 20 drops Contents Back Next

87. 87. Objectives To define action and reaction forces . To express the balanced and unbalance forces. To draw an object using balanced and unbalanced forces. Lesson 11 Action and Reaction Forces Action is when you push an object. Reaction is when an object pushes back on you with an equal and opposite force. See the picture above. The boy throws the ball on the wall (action), the wall pushes back with an equal and opposite force (reaction). Back Contents Next
88. 88. Balanced Forces Look at the picture. The weight of the flower vase is exerting a downward force on the table. The table is exerting an upward force on the book. The flower vase does not move. The two forces acting on the flower vase is balanced. When forces acting in an object are balanced there is no movement. Unbalanced Forces Look at the picture. The more people exert greater force than a single one. They can pull a rope towards them. These two forces are unbalanced. When unbalanced forces act in an object, the objects move towards the direction of the greater force. Back Contents Next
