Many children have a natural interest in science and perhaps science is one of those subjects that are the easiest of all to get children excited about. Science should be fun, adaptable with an environment that allows for exploration and hands on experiences. At the same time the science environment should appeal to all 5 senses of touch, smell, taste, hearing and sight.
Since science covers many areas, each of which children will be drawn to different subjects, variety should be established to capture the many and varied interests of the students. You may want to set up several learning centers in which the children are free to explore in their own time and in their own way encouraging activities and hands on approaches. Some of these centers may include a table for kitchen science, insect collections, weather instruments, rock and mineral collections, an audio center with headphones and science related programs to watch and hear, class pets, ant farms and whatever else you can think of. A small indoor archaeological dig may be a wonderful exploration table. Hands on learning centers are only limited by your imagination and the possibilities are limitless.
After teaching the Scientific Method, perhaps for homework you can have a list of ideas from which they can choose for at home projects having them come up with their own science experiment. After a set amount of time they are given to create their own science experiment they can turn in their papers and share their discoveries with their classmates.
Getting the children outside and active is always a great way to get them excited over science as well. Perhaps your school has a place for nature trails for exploring and discovery, if not plan a field trip to such a location. Plan other field trips as well where the places you take them to encourages hands on experiences.
Key factors in getting children excited about science are trying to appeal to all the interests of the students themselves. Perhaps at the beginning of the year have children write what areas of science interest them on slips of paper, putting them into a suggestion box. Take a look at the slips of paper and try to come up with activities that would bring these interests into the classroom where the lessons really come to life. To get the kids ready for upcoming tests, try setting up a classroom jeopardy game with teams for a fun way to keep information fresh for them.
One really does not have to try hard to get kids excited for science; you just need to bring in variety in ways that are hands on approaches. Be creative in hands on activities and projects and this will go a long ways in keeping them interested in science all year. Do not be afraid to find out what they themselves are interested in and bring some of these interests into the classroom. These things will ensure a whole year of science excitement, fun and a whole world of opportunities for discovery and exploration.
