The Earth Science Activities for Kids listed on this page contain key concepts and vocabulary for understanding geologic time and the plants and animals that lived during particular time periods.. There are words that may be unfamiliar to students with little experience studying geologic time. Yet even younger children of 8, 9, or 10 can be successful if they are introduced to this information prior to attempting the puzzles.
Elementary school children will do well if these puzzles are given as follow up work at or near the end of a unit of study of the time period corresponding to the selected puzzle. There are lesson plans for these Eras on the Earth Science Lesson Plans page of this web site.
Secondary students can do these puzzles as follow up to a lesson or they can be given the puzzles as an exploratory introduction. They should be able to research the answers themselves if they have adequate resources. There are many good books, charts, and other resources covering this material. All of the vocabulary and concepts can be found on the pages of the corresponding Era of this web site. (Links to the appropriate pages are given below the PDF link for the corresponding puzzle.) If your children have internet access, the link above will provide all they need to search out the answers. As an alternative, you could print the pages and make them available as reading or note-taking resources
The word puzzles listed on the earth science activities for kids page are free to print or download for educational or personal use. They may not be reproduced or republished for commercial use without written permission.
