Testing materials for flotation

Description

Being able to stay afloat, especially after a while in the water, gets harder and tiring for people.

Accidental immersion, where people didn’t intend to be in the water, but ended up in the water is a major cause of preventable drowning fatalities. This activity helps tamariki learn about traditional floatation materials and about modern day items including regular household items.

Lessons

Inquiry question - What strategies could our tūpuna have used to help them survive in the water?

Wānanga 1

 

1. Prior knowledge.

Brainstorm with students

  • What do you know about floatation?
  • Do you need to worry about being able to float when you go fshing, diving or swimming?
  • When would you need to float?
  • What objects float?
  • What objects sink?
  • Why is it important for us to know how to float?
  • What are some swimming styles we can use to help us stay survive in the water.

2. Teacher retells the story of Rauhoto and Te Urunga Or Hinepoupou who swam the Cook Strait. Rauhoto and Te Urunga:

http://nzetc.victoria.ac.nz/tm/scholarly/tei-Pom02Lege-t1-body-d3-d16.html

  • On a map look at the distance Rauhoto or Hinepoupou swam. Whole Class discussion
  • How do you think she could do this?
  • How would you prepare for a swim like this?
  • What methods would she use to float?
  • What strokes could she have used and why?
  • What floatation devices could she use?
  • What could Tuwharetoa have given her to help her float?

3. Survival swimming activities

Discussion of different survival strokes such as:

  • Dog paddle
  • Side stroke
  • Survival backstroke
  • Survival breaststroke
  • Sculling horizontally

Pātai: What did our tūpuna use to help them float and what could we use?

Teacher retells the story of Hinemoa and Tutanekai.

https://whakarewarewa.com/how-hinemoas-unrelenting-love-for-tutanekai-conquered-all/

  • Class discussion on what Hinemoa used to help her float?
  • What strokes could she have used to help her survive the long swim?
  • Why did she take off her clothes to swim?
  • Tamariki brainstorm and the teacher records all the different floatation aids that they know can support a person in the water (so they don’t sink). Both traditional and modern day materials can be included in the brainstorm.

Ask, what materials are these floatation aids made from?

Examples may include plastic, light weight wood such as cork or balsa, air (in inflatable devices), different fabrics, rubber, closed-cell plastic foams (PVC) and kapok.

Activity

Teacher places students into groups of four (or models with whole class). Each group has a bucket of water and is provided with samples of different materials and items to test for their ability to float for one minute or more (a piece of wood, pumice, hue, or wood samples with different densities, plastic, tin foil/aluminium, small plastic bottle, seaweed, denim fabric, other fabric samples such as polyester, wool, polar fleece and neoprene wet suit material). Tamariki record their predictions, carry out the testing then record their results. Tamariki then make suggestions as to why some materials are better in the making of floatation aids than others.

 

Wānanga 4

 

1. Pool session

Tamariki are put into peers. Each group are given a number of items such as plastic bottles, denim clothing, wetsuits, polyester, wood etc. In peers the tamariki are to try and use these items to help them float. Tamariki record which items help them to float.

2. Kia maanu Kia Ora (Akoranga WSL)
