Students eat celery sticks, carrot sticks, and dip.
Discuss plant part cut and paste homework sheet. I feel that the lesson was very effective, because the students met and exceeded all of the objectives. They were able to relate to the material, have hands-on experience, and have fun. The lesson ran smoothly because of how prepared the classroom was. The science center materials were ready to use, laptops were ready, as were the assignment papers and the digital camera.
