List the general science topics you will be teaching to your pre-K students. These might include animal identification, body-parts recognition, color wheels, comparing weights, growing plants, caterpillar-to-butterfly metamorphosis, food science or water cycles.
Write learning objectives for each science topic. Identifying what you want students to learn and be able to do after the lessons will guide you in selecting science projects that will help you meet your goals.
Visit your local library and look for books on science projects. Read some of the projects for older students and determine whether any of them can be adapted for your pre-K students.
Search the Web for preschool science lesson plans. Read each project carefully before deciding to use it in your classroom. Make sure that it fulfills your learning objectives and helps your students meet preschool science standards.
Brainstorm with a colleague. Meet with another preschool teacher and brainstorm ideas for science projects. Take a look at the list you made and the learning objectives. Talk about creative approachesand see how many ideas the two of you can come up with.
Attend conferences and workshops for preschool and science teachers. Network with other teachers and attend sessions on how to teach science in the classroom. Most teachers will be willing to share their lessons plans and project ideas.
