Energy is a really important idea in science. It lets us calculate what it is possible and helps us explain all kinds of processes. Let's find out more:
Task 1: Use look, cover, write check to learn the answers to the core questions and the keywords for this topic.
Task 3b: Make notes that:
Tell you how to find out how much energy is stored in an object.
Based on the experiment described in the slides, answer the following:
State the independent variable.
State the dependent variable.
List the control variables.
Draw a diagram of the apparatus
Task 4b: Make notes that:
Tell you how to write a method for an experiment.
How to stay safe during an experiment.
Based on the experiment described in the slides, answer the following:
State the independent variable.
State the dependent variable.
List the control variables.
Draw a diagram of the apparatus
Task 6c: Make notes that:
Define the conservation of energy
A log burner transfers 3500J into heat in the lounge. To do so it burns wood containing 6000J of chemical energy.
Work out how much energy is wasted.
Where did it go?
(click the arrow to check your answers)
1. 6000 - 3500 = 2500J
2. The wasted energy is used to heat up the log burner and some will be transferred to the surroundings as heat.
Task 6d: Watch the video (start at 1 minute) and name the energy stores full at these 3 stages:
Before the jump
When the slack has been taken up (rope not stretched)
At the bottom of the fall (rope at max stretch)
Task 10b: Make notes that:
Write a method to investigate how the height a ball is dropped from affects the bounce height.
List the independent, dependent, control variables for the above experiment.
Draw a results table that could be used.
Task 11a: Watch the video
Task 11b: Make a mind map or single page revision summary of this topic and add it to your revision folder.
