Basic 8 Science Term 1 Week 10 Lesson Plan

Revise with learners on the previous lesson.

Concrete-resource task: Set out these resources for each group: Clinical thermometer; Beaker of warm water; Beaker of cool water. Learners observe and safely handle the specimens or apparatus, using them in the investigation or model below. Brainstorm learners for meaning of temperature and heat Temperature is a measure of the degree of hotness or coldness of a substance Heat is a form of energy that is transferred from one body to another due to a difference in temperature. Create a table to show the distinguishing features of temperature and heat. 1. Definition: Temperature is a measure of the degree of hotness or coldness of a substance, while heat is a form of energy that is transferred from one body to another due to a difference in temperature. 2. Units: Temperature is typically measured in units of degrees Celsius (°C) or Fahrenheit (°F), while heat is measured in units of joules (J) or calories (cal). 3. Transfer: Temperature can be transferred from one object to another when the two objects are in contact. Heat, on the other hand, always flows from a hotter object to a cooler object. 4. Sensation: Temperature can be sensed by touch or with a thermometer, while heat is not directly sensed, but rather it is inferred from changes in temperature or other physical effects. 5. Dependence: Temperature depends only on the average kinetic energy of the particles in a substance, while heat depends on both the temperature and the amount of substance. 6. Effect: Temperature affects the physical properties of a substance, such as its volume, density, and state of matter. Heat, on the other hand, can change the temperature and physical state of a substance, as well as do work.

Use peer discussion and effective questioning to find out from learners what they have learnt during the lesson.

Share learning indicators and introduce the lesson.

Learners use a non-mercury laboratory thermometer or digital thermometer to measure the temperature of the Beaker of warm water and the Beaker of cool water and record both readings. The teacher then places the containers in safe contact through a controlled demonstration and groups predict the direction of heat flow. Learners distinguish temperature as a measurement from heat as transferred energy and explain thermal equilibrium. This component remains focused on heat and temperature; electricity transmission is taught next.

Take feedback from learners and summarize the lesson.

Revise with learners on the previous lesson. Share learning indicators and introduce the lesson.

Groups study the Printed Ghana electricity-transmission diagram and identify generation, step-up transformation, high-voltage transmission, step-down transformation, distribution and consumers. They arrange the Printed transmission-stage cards in order and join them with the String arrows to make a floor or desk flow model. Learners trace electricity from a Ghanaian generating station through substations to a home and explain why voltage is raised and later lowered.
