The science of rongoā — TEACHING RESOURCE
This article tells the story of Chris Ryan, a high school student who investigated the medicinal properties of kawakawa. Chris initially found there was no scientific evidence to support kawakawa as an antibacterial or antiviral agent. He found it odd that science did not back up the Māori practice of using kawakawa in rongoā – their traditional healing system.
Water bottle rockets
In this activity, students make a water bottle rocket. They investigate the variables that affect the height and distance travelled by the rocket.
Balloon car challenge
In this activity, students design and build a balloon-powered car to better understand the science ideas related to rocket propulsion. They use ideas of mass and force to work out ways to improve the distance travelled by their car.
Effervescent canister rockets
Effervescent canister rockets - In this activity, students make a film canister rocket using baking soda and vinegar. They develop their understanding of rocket propulsion and investigate the amount of vinegar that will make the rocket go the highest.
Investigating UV intensity
Investigating UV intensity - In this activity, students use UV beads to investigate the intensity of UV rays in a range of different situations.
Nutrient impact experiment
Nutrient impact experiment - In this activity, plastic bottles are used to simulate the link between land and sea. Students investigate some of the potential impacts increased nutrient use on land can have on the marine environment.
Water content of foods
In this activity, students quantitatively analyse carrot and banana for moisture content and total solids using and comparing two drying methods.
Strength of sand and cement mixes
Strength of sand and cement mixes - In this activity, students mix different combinations of sand and cement with water. Small tiles of these combinations will be fashioned, left aside to cure and then tested for bending or flexural strength.
Liming paddocks - In this activity, students measure the pH of soil collected from a paddock. This will be used to estimate the amount of agricultural lime needed to promote good grass growth.
