Individual student assessment results

Q: Is it possible to view a student’s assessment results/answers along with the answer key after the assessments are finished?

A: We are unable to share any assessment results beyond whether or not a student has demonstrated proficiency. With the absence of students being able to work together in teams, this year we really want to stress proficiency as opposed to competitive ranking. In addition, as WESO themes evolve over time, we do use one year’s test to inform and provide a format for the following year’s test. Therefore, we cannot provide individual test results or an answer key to students. 

Assessment Submission

We have received some questions today about how students should submit their Pear Deck Assessment. Please know that on our end we see student responses in real time and there is no final “button to submit” in Pear Deck. We added the final slide this month to let students know they have reached the final slide and have completed the assessment. At that point they can close the Pear Deck and know that their assessment has been received. All answers are final on our end once the Pear Deck assessment closes on Sunday, February 28th at 2:00pm.

We hope this helps to clarify the assessment submission process.

All About You DNA Information

Q1:  Why does the alcohol need to be very cold for this to work?
A1: DNA is soluble in water but not in alcohol especially in the presence of salt. It is even less soluble in cold alcohol which allows for better precipitation of the DNA.

Q2: Can you use this method to extract DNA from other fruits? Vegetables?A2: All fruits and vegetables have DNA but some will work better than others especially using this crude “kitchen” lab. Most cells are diploid, which means they have two sets of chromosomes but some crops are actually polyploids meaning they have more chromosomes. Strawberries are actually octoploids (8 chromosomes) so they yield a lot of DNA for a small amount. You also need to work with something that is easily liquified. After strawberries, kiwi and bananas (no peel for those) are your best bets.

Q3: What can you do with the DNA goop once you’ve got it? (it is currently labeled and stored in a small plastic container) Could you do anything with the DNA? A3: Unfortunately, without special reagents and equipment there is not much you can do with the DNA. In a lab, that DNA would be purified more and then could be sequenced, compared to other DNA from other strawberries or plants, cloned, and many other things.
