1. Students are in different level. I need to prepare too many different lesson plans for them to learn;
2. Some of the parents might not support the activities or they are too busy to take their accountability;
3. Some of the students are not interested in learning science or they are not good at English, since I teach bilingual science;
4. The time for the project is not long enough;
5. There are not enough computers or materials for them to really touch technology or science.
