- Bring their notebooks to class to take notes.
- Students must review lessons on the learning management system (LMS).
Agenda
- Getting to know the teachers.
- Classroom rules & expectations.
- Branches of science (e.g., Physics, Chemistry, Biology).
- Lab safety.
- Science in action.
Branches of Science
- Physics: The study of forces and motion.
- Chemistry: The study of matter, its reactions, and properties.
- Biology: The study of living things.
What is Science?
- Science is the process of observing, asking questions, and finding out about the world around you.
- The process used in science is called the scientific method.
What Will We Study in Science?
- Physics: Light, sound, electricity, and forces.
- Chemistry: Atoms & elements, acids & alkalis, chemical reactions.
- Biology: Plants, ecology, and reproduction.
Lab Safety
- A science lab is a room with equipment for scientific tests and producing chemicals/medicines..
- Safety is crucial in a science lab to avoid accidents.
- PPE (Personal Protective Equipment): Safety goggles, mask, earplugs/hearing protection, safety gloves, closed-toe shoes, hair net/helmet, and lab coat are essential safety gear.
- Activities like eating, drinking, running, playing and smelling or tasting chemicals are not permitted in the lab.
- Lab materials like broken glassware should not be used.
- Mixing chemicals without prior permission from the teacher is prohibited.
Lab Safety Symbols
- Highly Flammable: Substances that easily catch fire.
- Corrosive: Substances that attack and destroy living tissues.
- Toxic: Substances that cause death via swallowing, inhalation, or skin absorption.
- Harmful: Substances like toxic ones, but less dangerous.
- Irritant: Substances that cause redness or blistering on the skin.
- Oxidising: Substances that increase the rate of burning by supplying oxygen.
Science in Action
- Science can be used to solve environmental problems.
- An example of such environmental issues is plastic pollution.
Plastic Pollution
- Microplastics block UV sunlight needed by plankton for photosynthesis.
- Plankton serves as a major food source for marine creatures.
- Microplastics consumed by sea creatures impact the food chain.
Ways to Reduce Plastic Pollution
- Reduce the use of plastic.
- Recycle plastic.
- Clean up beaches and oceans.
- Educate people about plastic pollution.
The Ocean Cleanup and Adidas Initiatives
- The Ocean Cleanup: An organization dedicated to cleaning up ocean garbage.
- Adidas: A company employing recycled materials in product manufacturing to reduce plastic pollution.
Worksheet Practice
- Worksheets covering various scientific topics will help reinforce learned concepts. This will be a quiz for assessing class performance.
Next Week:
