This activity consists of nine word problems that directly correlate to science topics. Topics included are weather (temperature and barometric pressure), and dynamic earth (earthquakes, volcanoes and ocean floor spreading). Adding and subtracting positive and negative integers are imbedded in every question. There are two problems that have decimals. Visuals (charts, graphs, number lines, thermometers, barometer) accompany each question to help lower level learners. Check out the preview f
