Weather Dot Com
Students examine the need for a standard unit of temperature and measure temperature with a thermometer. They discuss the details of a thermometer and the calibrations used, record temperature data for inside and outside, explore...
Curated OER
Our School - Our Trees
Sixth graders observe school ground trees planted nearly 3 decades ago. For this ecology activity, 6th graders examine a group of trees planted near their campus and measure the diameter, circumference and growth of the tree...
Curated OER
Finding Areas of Triangles, Rectangles, and Circles
Students find the areas of geometric shapes. In this geometry lesson students find and measure the sides, perimeters, and areas of quadrilaterals, triangles, and circles. Students relate the measures to the others by using formulas.
