For project 3A, we will learn the concepts of conservation of energy, kinetic and potential energy. We will also learn how to use materials like photogate ,smart timer and photo-gates. We will record the time taken for the ball to travel across the distance of track. We will learn how to determine the angle of inclination.
For 3B, we will learn about caffeine which is a type of alkaloids. In this project, we will learn how to extract caffeine from different beverages. Also, this teaches us about chemical solvents and reactions benefitting our knowledge.
