Lab Experiment #2 For My Biology Students – Grades 5-6

To Do: I would like my students to research some experiments of there choice and of something they have interest in. I would  like them to

  • Present a Question for the experiment
  • Perform it with One Partner
  • Present the experiment in Video Format
  • Upload to YouTube

My Example – My Question to you is: What do yeast like to eat?

  • Yeast is a fungus and it likes to eat, just like me and you
  • Yeast produces Carbon Dioxide just like me and you
  • Yeast will grow when it has food and water
  • Yeast can be used in baking and if you take a slice of bread and if you look at it carefully you will see bubbles which are the Carbon Dioxide bubbles produced by the yeast
  • I will be using Sugar, Salt, Flour and the Control which will just have yeast and water, then to each I will add one packet of yeast and water.
  • I am using zip block bags so I will be able to capture Carbon Dioxide.
  • Next, I will identify what the yeast likes to eat by the amount of bubbles produced which is the Carbon Dioxide.
  • Does it like Salt? Does it like Flour? Does it like Sugar? Or None? Watch the Video and Enjoy!

In order to do this assignment I used the video camera on my phone to record and then I uploaded the video to YouTube.

  1. This is a good experiment I will have to try it with my nieces. and you can include a hypothesis for your students or background info so that they can make a hypothesis they can test.

  2. Love the fact that you did the experiment and showed your students exactly what you are expecting!

  3. This is very interesting! i actually learned something new definitely trying this with my students.
