I used this activity for my students who were absent the day we did the actual lab. It's great for an alternative to the actual lab since students can use an online simulator to view different slides. I like that there is a writing portion to it.
This was a fun activity after introducing the metric unit. My students struggled with the difference between cm and mm. After demonstrating how to find mm using a ruler they FINALLY understood that 10 mm = 1 cm.
Thank you for purchasing this project! I hope your students enjoy it:)
1. The chromosome strips are double sided. One set is for the mother (with the XX) and the other set for the father (XY). One side will have the letters and the other side the numbers.
You can start by cutting off the two strips on the left- A and a. These are your first two strips. Then cut on the next vertical line. This includes two different strips Q and X. Cut on the horizontal line to divide these two. Do the same for the next full strip which will be divided into q and Y. The remaining strips will work the same way. At the end you will have a complete set for one parent.
2. I used colored paper or construction paper for the ears.
3. I had my students use the chromosome strips one time and create one offspring. Strips could be used for a second round to create a sibling and then students could do a comparison of the traits. Due to time constraints and availability of supplies my students just create one bag puppet. The strips could be used multiple times though with data collected on siblings (without actually building the siblings) and then analyzed.
4. For Arthur and Anne I used colored toothpicks and regular/natural colored toothpicks. For Cliff and Connie I used colored pipe cleaners and white pipe cleaners.
Hope this helps! Please let me know if you have any other questions.
