Introducing the concept of thermal capacity which is developed into the SHC equation. Worked examples and questions with answers included.

The basics of current in series and parallel circuits. The distribution of voltage in a circuit.

Following on from the last lesson we consider the ideas of voltage and current. Key learning points caption and a knowledge check with answers.

This work tries to develop an understanding of what speed actually means using common phrases and a range of questions.

A range of circuits with bulbs and switches. Combinations of switches are closed, you have to follow the path of the current to decide which bulbs lights. Answers in separate document.

Characteristics of a reflection diagram from a plane mirror are identified. There is a set of data to graph. A gradient calculation is shown giving a result of 1 which matches the incident angle to the reflected angle which in turn supports the law of reflection. Comments on the reliability of the data are then made.

Energy types identified. Activities are given energy values and total energy required calculations are set. All solutions are shown at the end.

Start from the beginning of your understanding of forces. Diagrams and explanations of the most common forces and common misconceptions identified. A ‘name that force’ assessment at the end with an answer page. It would work nicely as a home study resource, that’s what it was written for.

A nice little activity dealing with cooling and warming data. Graph plot which can be printed and completed on paper or completed electronically. Questions about the temperature change and explanations included. Designed as an online resource but would work in the classroom.

The resource compares the concept of work and power. Calculations and answers included.

Introducing static charge. It covers the principles of positive and negative charge. Conductors and insulators. Like and Unlike. Attract and Repel. Discharging. It would work in the classroom or as an online resource.

Data set for analysis. Follow on from Investigation refraction1. Solution in accompanying file.

Practical description of this investigation. Analysis of measurements demonstrated. Data for analysis and evaluation included. Designed as an online resource.

An extension of refraction1. Lots of ray diagrams with labels. Introduction of refractive index equation.

Determination of the time period from a range of wave diagrams.

Following on from thermal energy1, this resource focuses on the relationship between change of state and temperature.

Introducing the relationship between thermal energy, temperature and kinetic energy of particles.

Building on the ideas from Resultant Force1. This work analyses a skydiver in freefall who then pulls his parachute. How the forces acting vary and how this changes the resultant force and hence the acceleration. There is a Resultant Force3 file which assesses the learning from this work.

Detailed description of the conditions for total internal reflection. Calculations and solutions included. Designed as an online resource, would also work in the classroom.

This work matches the characteristics of the waveform to the pitch and volume of a sound.
