Before beginning this space worksheet, remind your child about some of the aspects of outer space. For example, what planet do we live on? Who are the people who travel to outer space for research? Then, remind them that a preposition is a word which is used with another word to show location, direction, or time. After these questions, look at this colorful worksheet. Each of the pictures below shows an astronaut engaged in an activity. Help your kids draw a line to the words that complete each sentence.
