Teachers shouldn't be afraid to teach kindergarten children science topics. Science lessons that are highly interactive keep their attention and spark an interest in the subject. Earth science might involve collecting samples from all around the school playground and describing all of the different kinds of substances and weather patterns. Physics and chemistry lessons may involve taking apart natural and mechanical things, under the close supervision of the teacher. Students may take part in ice experiments, measuring when water freezes, collecting snow and generally asking each other questions and making simple observations about the nature of the world around them.
Personal safety is an important topic for kindergarten classes, and parents often expect teachers to incorporate the subject into their lessons. Teachers should ensure that children are aware that avoiding strangers doesn't only mean the stereotypical cartoon villain but also apparently unassuming people. Children should also be taught about the authority figures to look for if they're ever in trouble.
Math may seem like a daunting subject to approach in kindergarten, but children love to solve puzzles --- there's no reason teachers can't have fun with it. Use a variety of props to illustrate mathematical concepts; numbers should refer to actual objects that the children can see and feel. Avoid too much structure, and let the children play with counting and subtracting before introducing more abstract written problems.
A love of poetry and prose may be instilled in children from a very young age. Conduct story time for half an hour every day, and instruct the children to practice speaking a poem in chorus. Kindergarten children should be able to identify rhyming words and meters, especially in songs and nursery rhymes. Ask the class to perform a play every term --- get them involved in every stage of the production, from acting and set design to directing.
