Term 3 CAPS Framework: Energy and Change. A colourful study hub about energy around us, energy transfer, movement, sound, vibrations, musical instruments and noise pollution.
In Term 3, learners explore how energy is used and transferred in everyday life. They learn that energy can cause movement, produce light and heat, and make sounds. Learners also investigate vibrations and how sound travels through different materials.
Energy is needed to make things happen. People, animals, plants, machines and natural processes all use energy. Energy helps us move, see, hear, cook food, keep warm and do work.
Name three things in your home or classroom that use energy, and explain what each one does.
Energy can be transferred from one object or place to another. Many devices change energy from one form into another useful output.
Energy from batteries is transferred to the bulb and becomes light.
Electrical energy is transferred to water and becomes heat.
Electrical energy is transferred into sound energy.
Movement needs energy. When something moves, energy is being used or transferred. People use energy from food to walk, run, push, pull and lift objects.
Use a toy car and ramp to investigate how the height of the ramp affects how far the car travels.
A system is made of parts that work together. In Technology, learners look at systems to understand how energy is used to solve problems or make tasks easier.
How can you improve your design so that it moves more smoothly or travels further?
Sound is a form of energy that we can hear. Sounds help people communicate, enjoy music, notice danger and understand what is happening around them.
Explain why a guitar string makes a sound when it is plucked.
Different vibrations make different sounds. Fast vibrations can produce higher sounds, while slower vibrations can produce lower sounds. Stronger vibrations usually make louder sounds.
Pitch tells us whether a sound is high or low. A short, tight string usually makes a higher sound than a long, loose string.
Volume tells us whether a sound is loud or soft. Stronger vibrations usually produce louder sounds.
Musical instruments are designed to make sounds in different ways. Some use vibrating strings, some use vibrating air, and some use vibrating skins or solid materials.
Guitars and violins make sound when strings vibrate.
Recorders, flutes and whistles make sound when air vibrates.
Drums, shakers and bells make sound when struck, shaken or tapped.
Create a simple instrument. Explain what vibrates, how the sound is made, and how you can make the sound louder, softer, higher or lower.
Not all sounds are useful or pleasant. Noise pollution happens when sounds are too loud, disturbing or harmful. It can affect people, animals and the environment.
Each concept can later be linked to detailed notes, interactive worksheets, immediate marking and complete learner feedback.
