Materials and their uses

This topic covers terms used to describe the properties of objects or materials; different materials used in the construction of the boats and why these different materials are used; different materials used in the construction of the crew's clothing; and why these different materials are used.

The resources in BT STEM Crew can be used either in sequence or flexibly as an introduction to a topic, or for a quick activity.

Introduce the topic of materials with a short starter film, discussing how choices made on materials used in clothing and boats relates to those that will give the best performance. Test students' knowledge with an engaging interactive. Our differentiated worksheets reinforce learning objectives for this topic.

Film

 Take a look at what materials are used to make Land Rover BAR boats - what properties do they have and why have they been chosen?

Interactive quiz

High performance depends on the right design and materials, so the boat has the properties it needs to deliver top speed. Test your students' knowledge of the properties of different materials and their uses.

Teacher's notes

Starter

To introduce the topic you could have a variety of objects/materials with different characteristics to show students, and ask them to think of three adjectives to describe each one. If necessary, show a list of words such as strong, stiff, hard, flexible, elastic, and absorbent. Check that students understand the meanings of the words, or give an example of each (for example, a biscuit is stiff but not strong, nylon fibre is strong but not stiff).

Suggested activity

Students test different fabrics for water absorbency, or strength test different materials.

Plenary

Students look at materials used for the boat, equipment and crew gear, and think of other applications these materials could have in other areas, such as in other sports, or in everyday life.

Further ideas/ STEM Club ideas

Students could receive a design brief to design a new piece of equipment or clothing for use in a maritime setting. Students could draw up their designs with full annotation and even make a prototype.
