Inside The Atom.
An atom has a small central nucleus that contains protons and neutrons. Protons have a positive charge, neutrons have no charge, and together they make up most of the atom’s mass. Surrounding the nucleus are electrons, which have a negative charge and are arranged in shells. These electron shells help explain how atoms behave, bond, and take part in chemical reactions. Understanding atomic structure gives us a strong foundation for learning the rest of Chemistry.

How Particles Spread Without Being Pushed. Diffusion happens because particles are in constant random motion. According to kinetic particle theory, gas and liquid particles move freely and collide with each other, causing them to spread from a region of higher concentration to a region of lower concentration. This continues until the particles are evenly distributed. The process is faster in gases because particles are farther apart and move more quickly than in liquids. Understanding diffusion helps us connect particle motion to everyday observations, from perfume spreading through a room to food colouring dispersing in water.

Time flies by so fast. Make the most of each day while it lasts. #

2024 Science fair show. Was quite proud of the amount of work these kids put in their projects. Very long hours of hard work including weekends.
