For a student preparing a science fair project, identify the key advice on ensuring experiment reliability and accuracy. Additionally, list the core activities involved in a technology project as described on the website. Provide all details found on the 'Practical' page.
Navigate directly to 'https://scifair.org.nz/practical.html'. Scroll down the page to locate the 'METHOD RELIABILITY AND ACCURACY' section. Extract the advice for ensuring reliability and accuracy. Continue scrolling down the page to locate the 'Technology' section. Extract the core activities involved in 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.
