Math Skill: Identifying three-dimensional objects

Science Skill: Earth Water / Pollution

Grade level: 3rd – 4th grades

Area level: Community-scale

Environmental Area: Water

Purpose: Identify three -dimensional objects, including rectangular prisms, spheres, and cylinders, and develop awareness of air quality



The availability of our water resources is limited, therefore, it is critical to keep our water clean.  However, our water sources are susceptible to water pollution.There are many causes of water pollution that are associated with human activities. Urban development, farming, industry, stormwaterrunoff, wastewater from septic tanks and sewers, ocean and marine dumping, oil spills, underground storage and tube leakage—these are just some of the sources of water quality degradation.  Even fertilizer and pesticides from our lawns can be a cause of water pollution. Also, natural phenomena, including storms, volcanoes, algae blooms, and earthquakes, contribute to water contamination.

The purpose of this activity is to 1) identify three-dimensional objects and 2) raise awareness of water pollution.

Two problems are provided to match students’ levels of understanding.


Worksheet & answer key

Math Skill: Identifying three-dimensional objects

Students are asked to identify the shapes of the items by looking at the pictures of them. Shapes include rectangular prisms, spheres, and cylinders. The first worksheet (Problem A) includes images of each solid and the other (Problem B) does not.
