Activity 11 through Activity 15 require students to complete challenges to meet numerous high level problem-solving objectives. The objectives for the challenges in Activity 11 through Activity 15 of this PAC include: Challenge 1 You will conduct research on a career of your choice in the plant science field. Share your findings in a presentation. Challenge 2 You will research and present information about plant parts. Challenge 3 You will use common household materials make a plant press. Challenge 4 You will dissect one of the flowers from your plant and label the parts. |
