Grade 3 Science · Life Cycles
Explore Grade 3 Science with five 10-question practice tests on the stages, order, growth, and changes in animal and plant life cycles.
These Grade 3 Science practice tests help students identify the stages living things go through as they grow and change. Students explore butterfly, frog, plant, mammal, and bird life cycles.
Identify the organism first, then look for clues about its stage. Use words such as first, next, young, adult, and finally to place stages in order. Remember that different organisms have different life-cycle patterns.
