What to do when your experiment fails

March 1, 2014 Ticia 14 Comments

It’s been a lovely break from running Science Sunday, but it’s time to take it back up and have the responsibility of running this again because it makes sure I get more science done than I have recently.

What to do when your experiment fails

I have to admit part of why we haven’t been is because our science experiments and demonstrations have been failing.  More often than I really care to admit.  So today let’s talk about what to do when your experiment fails.

 

Because there are times your experiment turns out like this:

 

First look at why it failed

Here’s some questions to look at when you’re looking at why your experiment failed:

  1. Did you have the right equipment?
  2. Did you follow the procedure?
  3. Did you measure correctly?
  4. Did you put it in the right place?

what to do when your experiment fails change the materials

We attempted to build a model of the lungs, and gathered all the materials we were told to, and then built it, but it didn’t work.  The 2 liter jug kept collapsing under the pressure of the balloon.

 

Next what can you change?

Once you think you know why, can you change the reason it changed?

 why did your science experiment fail

We tried an experiment to see how the mucus in our nose collects debris and keeps it from getting into our lungs.  At the end of several days sitting on my counter, all we had proved is the water side dried and became wavy, and the honey was sticky, but had gathered nothing.

I think if we repeated this experiment I would try sprinkling dirt on the paper and demonstrating the honey catches it and keeps it from going anywhere, while the water side does nothing.

 

Repeat your experiment with the changes

If you have the time AND ABILITY to enact the changes, try the experiment again.

We tried the lung model using several different bottle variations, nothing worked, sometimes you just can’t get something to work.

I had a hangout on air, and was sent the kids upstairs with instructions to try different exercises and record how many times they breathed.  They came back with results anywhere from 2 to 500.  They obviously failed to measure correctly and to follow procedures.

We repeated it with me showing them how to measure it and got much more reliable results.

 

If you keep at it, and keep trying after your experiment has failed, then you can get the joy of seeing your experiment work:

Now link up your SCIENCE posts for the week, and then visit some of the other posts linked up and say hi. I’m going to be pinning, commenting, FBing or tweeting all of the posts linked up as the week goes by.

    I love this post. I am very familiar with the science experiment that does not work…we have had many of them! I loved seeing your videos. I have the lung demo on my list of things to do…now I am not so sure. LOL The rocket looks like fun, though. Thanks for hosting Sunday Science.

      I saw a couple of people on pinterest who’d done it successfully, but none of them had specific directions, and I went through all the posts on my pinterest board. I was really rather disappointed.

    We’ve had our share of damp squibs too, but as you say it’s all good scientific experience. I love the way your kids are full of suggestions for why the first rocket didn’t go off.

    Lovely to see you back with Science Sunday. We’ve been reading about black holes this week so nothing hands-on to link up but next week we’ll be trying to measure the speed of light (wish me luck with that one) so I’ll be heading back then.

      Good luck with that, and at the very least share what books you’ve read because we’re doing astronomy next year.

    We’ve been a bit lax with science over here too, but we are raring to go for the next few weeks. Suddenly, it seems, we have caught the science bug and the children can’t get enough of it!

      Isn’t that the way kids are? Suddenly that’s all they want to do. Superman has been obsessed with mysteries lately.

    Great post, Ticia. If at first you don’t succeed, try, try again!

      Exactly! Of course there’s just some that I’m not willing to retry because I don’t find them THAT interesting, but I always try to give them a couple of tries.

    Glad to see Science Sunday return 🙂 Your scientific approach to what went wrong sounds really good! I will also link my failed experiment post 🙂

      Sweet! In a lot of cases there’s almost as much to be learned form a failed experiment as there is from a non-failed one.

    I think it’s good when the experiments don’t always come out as you expect. After all, that’s real science, and it gives them a chance to go over again and see what, if anything they did wrong or could try differently.

    We’ve had our fair share of failed science experiments, which always exasperates me! But these are great opportunities for learning so we always keep trying until we get it right.
