12. 5 4 How valuable were the student reading materials in A Changing Cosmos? Very valuable (1) Valuable (2) Overall, how successful would you say your Hands on Universe curriculum has been, using A Changing Cosmos? Very Successful (1) Successful (2)

13. 5 How valuable were the student reading materials in A Changing Cosmos? • The readings matched what the students were expected to know and provided background information needed to do the activities. • It tied in the HOU IP program with course content. • The students were able to understand the concepts better after the readings.

14. 7 & 8 Was the Teacher Guide helpful? 2 helpful - 1 did not use them I like knowing what I am supposed to get for an answer (at least, a sample reference answer!) to judge if I am doing the activity right. Not knowing possible answers and not understanding the directions (for me) makes me afraid to try the activity. Luckily, you did the guide very well! I could only print a portion of the Changing Cosmos sample text as my printer is old and ran out of ink (and is slow.) I liked the explanations given .

15. 10 Chapters used/rated.

16. Investigations Used

17. 13. Suggestions Finding Supernovae - This was VERY difficult, lots of steps that had to be done precisely. The kids that did it, did it well, but a lot of them just couldn't figure it out. Tracking Jupiter's Moons - Excellent! Exoplanet Transits - Not yet.students not quite ready for it. Needed a lot of explaining Hubble's Law - Ran out of time. I just did a graph instead showing the relationship between distance and acceleration. Using Star Maps - worked better with the upper level students Browsing the Universe - A favorite! I do this early on before they know what a nebula or galaxy is. Size and Scale of the Sun - Too much math for some of my lower end kids.worked even with limited English speakers Parallax - Too much math for some of the lower end kids. I thought it was great!I use a Discovery Channel activity too Inverse Square Law of Brightness - students were a little confused

18. 14 What did you find most valuable about teaching the curriculum?(for you personally, for you as a professional, for your school) Being able to use REAL imges, real data, not just canned labs. Connecting Hands-on with content curriculum The students received a better understanding of how their universe works, not just their immediate surroundings. They like looking at the sky now. What was the most difficult part of teaching the curriculum? Most of the students had no trouble doing the computer work, but some could not be motivated to do the math. Many kids dislike doing (or learning) the program because they have become accustomed to passive learning techniques. The students have a very limited vocabulary and set of basic understandings. 15

19. What challenges or barriers did you experience? Some technical problems, computers that did not run/work, etc. Limited English, limited math skills, and indifference to science as a whole. What would you do differently next time? I'll do MORE! Simply remind them that, like anything else, without effort on their part, they will not improve and this content is hands on. Set up a night sky viewing party to start the program. Then have one once a month to keep the excitement going and to practice skills. 1617
