Half-Life Practice Worksheet + Answer Key
$16
Half-life problems split into two very different skill levels — and most worksheets don't make that clear. This one does, walking students through both before asking them to solve 20 problems on their own.
✅ Clear definition of half-life and the full equation, with every variable explained in a labeled key
✅ Worked example showing how to find the amount remaining — solved two ways: with the equation, and with a simple halving table, so students can check their work either way
✅ 10 practice problems finding the amount remaining after a given time
✅ Clear explanation of why logarithms are needed once the unknown lands in the exponent — and a fully worked example showing the log method step by step
✅ 10 more practice problems solving for time elapsed or half-life itself, using logs
✅ Built-in work space for every problem
✅ Full answer key included, with every calculation verified
✅ Instant digital download (PDF)
Most half-life worksheets only cover "plug and chug." This one builds real understanding — including the algebra-to-logarithm jump that trips up so many students the first time they hit it. Created by a chemistry tutor with 5+ years of experience helping students actually understand this stuff — not just get through it.
