Did you know that the patterns on the tips of your fingers are unique? It’s true! Just like no two snowflakes are alike, no two people have the same set of fingerprints. In this experiment, you will be using a chemical reaction to generate your own set of blood-red prints.

There aren’t any other experiments, but an alternative is to make your own goldenrod paper. Here is a link: http://blog.teachersource.com/2014/02/05/make-goldenrod-paper/
Is there any other experiments with goldenrod paper? Because i don’t want to buy an 100 pack if i am not going to need it again.
We share a link for goldenrod paper on the Unit 19 shopping list, which is available here: https://www.sciencelearningspace2.com/2011/11/shopping-list-for-unit-19/
Where could i find goldenrod paper?
It is best to use baking soda or sodium carbonate (washing soda) for this experiment because it works best with something that is a base, not acidic.
what if i used lemon juice since its acidic?
Oh, no! That doesn’t sound right. I’ll have Tonya reach out and make sure your account is set up correctly. And yes, you should have access to all of it!
We just bought the Master Diamond (?) science experiments and got the 5 years of free curriculum with it. Now we can no longer access the Human Anatomy and Biology course. Is this course still available to us? How do we access it? I may have misunderstood what we were getting when we made that purchase. Help! 🙂
That’s not right! I’ll fix the written instructions so they match the (correct) video.
In the video you pour water into a cup and add baking soda-the written directions say to pour baking soda on a paper towel and add water. The ratio of water to baking soda in each method will be very different. The first video method creates a watery mixture and the second creates a paste.
We used baking soda and water with the method described in the written directions and the directions on the video. Neither method produced any red coloration at all on the goldenrod paper you sent us. The paper just got wet.
The written directions should be about the same as the video instructions. What did you notice that was different? (I am also wondering if I sent you the right paper – we have four shades of yellow here, and only one will chemically react!)
What chemical did you use with the water?
Oops – thanks for your eagle eye! We’ll get that fixed.
For editing purposes…The answer to #4 is printed on the student work sheet.
Hi Aurora, this is Alex. I was wondering about the difference between the video and the written directions. Is one way better than the other? Neither seems to be working…
Hi Aurora. We are using the sheets of paper you sent us. The paper is just getting wet and not turning color at all. Do you have any ideas why? My son got a piece of yellow cardstock and had the same result.
I’ve sent you a private email.
Hi Aurora,
Checking to see where we could purchase the goldenrod paper?! Thanks so much!
No not easily, but you can do a similar experiment using cobalt. Look at “Cobalt Colors” experiment!
Can you make goldenrod paper?
Try it! 🙂 (with parent supervision, of course, since you are using ammonia. And wear GLOVES – don’t touch the ammonia with your bare hands.)
what color would it be if you used ammonia.
Well, if you don’t tell anyone… me! I am happy to send you a few sheets. We aren’t really set up for this, so I can do this for you as my gift to you. Send me an email with your mailing address and we’ll get it out to you right away. 🙂
Hi Aurora,
Where can we find a good source for the goldenrod paper?
Thank you!
Lisa
And no, turmeric will have a different reaction (refer to the Matrix for details).
Send me a private email and I’ll forward it to my team. 🙂 We’re not really set up to do this, but we’ll make an exception just for you as a gift. 🙂
If I make the paper with Turmeric will it have the same reaction? I read that I can spray the paper with 2 parts water and 1 part ammonia, then do the dip the fingers in equal parts baking soda/water mix…..
Having a hard time coming across the paper as well…
I’ll have my team connect with you right away!
As with the others, I too am in need of Goldenrod paper. Where can this be purchased? I would be happy to pay for the paper and shipping if you have some.
I’ll send it to you free of charge. Send me an email with the mailing address you’d like me to ship it to, and I’ll get you a couple of pieces so you don’t have to worry. This is my way of saying thanks for the great feedback on the program, and letting others know about it!
Hi Aurora – can I purchase goldenrod paper from you? I have found some online, but worried I will buy the wrong type of paper…thanks!
Oops! We’ll get that fixed. Sorry about that!
Editing: The answer to the last question – What kind of reaction do we see when the red fingerprints show up on the paper? – is given on the page – (a chemical reaction)
Hi Terri,
Thanks… and you’re right! I’ll look into a good resource and post it when I find one. The one we use only sells it by the case of 5,000 sheets, so at the moment I am offering to send you a few in exchange for writing a review of the e-Science program using the guidelines here.
Aurora – we, too, need a source for the “right” goldenrod paper. Are there any links since I expect you’ll be getting more requests and your staff isn’t a fulfillment center. 😉
Not to worry! We’ve got not only golden rod paper, but the *right* kind of golden rod paper (not all goldenrod works!) I’d be happy to send you some. I’ll have my team contact you for mailing info.
Hi Aurora , my son has this experiment next on his list. We were wondering where we would find goldenrod paper? Is there a brand name that I could look up? The only science shop in our area didn’t even know what I was talking about when I phoned to see if they carried it.
Here’s a fingerprint guide you might like!
Aurora, in #3 you state “Compare your prints to the basic patterns in the guide.”
Where is this “guide”?
what is the online gide called?
Cool! Can you send me a link so we can share it with the rest of the kids? It sounds like a lot of fun!
I found a guide online so the kids can identify the different patterns in their fingerprints. Thank you for getting back to me.
Whoops – sorry about that… thanks for asking again. I am not sure about a ‘guide’… was there something you needed clarification on, like how to do a particular part of the experiment? Or how to extend the experiment somehow?
You spoke of a fingerprint guide in the goldenrod experiment. Where do we find that? I know this is a duplicate question, but I didn’t get a response before. Thank you.
