2. The lab experiences were very similar to real research.	6.00	0.00	4.27	1.34	15.00*
3. The lab experiences made me realize I could do science research in a real science lab (for instance, at a college or with a pharmaceutical company).	6.00	0.00	4.38	1.33	15.00*
4. Lab experiments presented real science to students, similar to what scientists do in real research labs.	6.00	0.00	4.23	1.42	12.00*
5. I better understood the ideas of biology, in general, as a result of completing the experiments.	5.83	0.41	4.40	1.47	25.50*
