On the 'Practical' page, what are the key pieces of advice for ensuring experiment reliability and accuracy in a science fair project? Additionally, what are the core activities involved in a technology project as described on this page?
Navigate to 'https://scifair.org.nz/practical.html'. Locate the 'METHOD RELIABILITY AND ACCURACY' section and extract advice on reliability and accuracy. Locate the 'Technology' section and extract the core activities for a technology project.
State the advice for reliability, including: repeating trials and averaging results to reduce errors from random variation (e.g., repeating experiments 5 times and averaging; timing 10 swings of a pendulum and dividing by 10). State the advice for accuracy, including: using good measurement tools and techniques (e.g., reducing parallax error; using the smallest scale possible; using equipment that removes human error like optoelectric sensors or automatic ball launchers). List the core activities for a technology project: designing a solution to an identified problem or need that serves a real purpose, functional modelling, prototyping, or using materials to build a solution, and examining the fitness for purpose of earlier technological outcomes and making informed predictions about where things can go in the future.
