After sufficient materials have been covered, they are challenged to explain it.<\/p>\n\n\n\n<p>However, unlike in&nbsp;MYP&nbsp;science, their write-ups aren&#8217;t always graded. Some times the discrepant event write-up may be graded and contribute towards their final grade just as a quiz would.&nbsp;Some times, it may be graded according to one or more of the IA criteria. And some other times, it may lead to a design investigation.<\/p>\n\n\n\n<p>What a given Discrepant Event requires is made clear at the time it is demonstrated.&nbsp;Regardless, the Discrepant Events published on this blog contain guiding questions to help you.<\/p>\n\n\n\n<p>IB Diploma Chemistry discrepant events are labeled with either the prefix DP1 or DP2 which refer to first year and second year respectively.<\/p>\n\n\n\n<p><strong>IBDP year 1 Chemistry Discrepant Events<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><a title=\"DP1 Gunpowder: Ideal Mixture\"
