Lesson Plan Science
Objectives
To describe the orbits of the sun, earth and moon; to read temperature values from a line graph; to identify symbols in a circuit diagram; to describe characteristics of different climates; to describe the processes of evaporation and condensation; to investigate the sound insulating properties of certain materials; to choose appropriate equipment, strategies and scientific knowledge to solve a range of problems.
National Curriculum
KS2 Science, Life processes, Materials and their properties, Physical processes.
QCA Science Schemes of Work: 5D, 5E, 5F, 6D, 6G, 6H.
Resources
Worksheets The Solar System, Evaporation and condensation and Sound.
Radio, samples of the following materials: sponge, carpet, cotton wool, cardboard, egg box, bubblewrap.
Introduction
Distribute the worksheet Sound to the class and show pupils the equipment to be used.
This investigation is one of a series of science challenges set by Digger and the Gang. Other challenges include problem-solving online and completing paper-based puzzles. Set up a rota to ensure all pupils have an opportunity to try the Sound investigation.
Group Work
Setting Course
Pupils help Digger and the Gang set their course by supplying information about the sun, earth and moon.
After the online activity, pupils use a line graph to identify the correct temperature-setting for the spacecraft .
Pupils complete the worksheet The Solar System.

Spacecraft Checks
Pupils identify components in a circuit diagram and adjust the pitch of the spacecraft’s speaker system.
Pupils list high-pitched and low-pitched sounds, e.g. bird song / thunder. Who can make the longest list?

Crash Landing
Pupils follow prompts in the story to identify characteristics of different climates.
Follow up the online activities by completing the worksheet, Evaporation and condensation.
Individual Work
When not working at the computer, pupils have a brief opportunity (5 minutes will suffice) to complete the worksheet Sound.
Pupils can also complete the Fun &Games activities Create a secret code message and Music mixer.
Plenary
Pupils compare their results in the Sound investigation.
How did different individuals / groups interpret the column heading 'Level of Sound'? (e.g. by giving each entry in the column marks out of ten, by using a verbal description such as 'clear', 'muffled' etc, or by indicating the volume level of the radio which could be clearly heard.)
Pupils vote on the interpretation of 'Level of Sound' which best suits the investigation.
Homework
Ask pupils to make a note of any 'try this at home' activities they come across during the online adventure. Either:
Pupils watch the moon on successive nights and see how it appears to change in shape from a cresent to a full moon. What is happening?
Or
Pupils try star spotting. From a chart, they try and identify stars.
