Art is a broad topic that encompasses everything from ancient cave paintings to modern day art. Art lesson themes can focus on different time periods in art, various styles, specific artists or specific pieces. A unit on Pop Art should include a study on Andy Warhol and his work that gives nod to commercial art. Show examples of Warhol's art and use it as a jumping off point for students to create their own Pop Art-style work.
Another art lesson theme is sculpture. This lesson should show sculptures from various artists and time periods. Show different materials that can be used to create sculpture and allow students to experiment with the various mediums. A field trip to an art museum is a must for any art-themed lesson plan.
It's important for students to have at least a basic knowledge of biology so they can understand more about their own bodies and the living world around them. An important theme for a children's lesson plan is the human body. Help students create skeletons gluing various types of pasta and other dry foods onto paper. Spaghetti noodles work well for arm and leg bones, while rice makes great finger bones and vertebrae.
Another biology theme is Environmental Biology. Teach students about biomes, photosynthesis and other related topics. A walk around the neighborhood collecting natural, found objects will give children the opportunity to closely examine leaves and other natural items.
A study of geography can take on many themes. Choose a specific country or region to focus on and create a whole lesson plan around this central theme. A unit on the country of Japan can include showing the children examples of Japanese art, allowing them to taste various teas and letting them use chopsticks. Choose a Mexican lesson plan that encourages children to learn to speak Spanish, and visit a Mexican restaurant as a field trip.
A music-themed lesson plan will give children the opportunity to explore their creative sides. Choose a specific time period or style of music as your theme. Alternately, you can choose to focus the theme on a specific type of instrument such as the drum. Explore how the drum is used in various cultures as well as the different types of drums that exist. Teach about beats and rhythm and go to a concert where the drum is highlighted.
