Matching nutrient ppm in soil
Matching nutrient ppm in soil
Hi all! For my experiment, I'm comparing vermicompost tea and Miracle Gro water soluble fertilizers in terms of nitrogen runoff in soil. So ideally, I want the nitrogen ppm of the vermicompost tea and the water soluble tea to be the same.
In order to find the nitrogen ppm of vermicompost, I added 1 part of solid vermicompost to 5 parts water, waited for the sediment to settle, and tested the solution. The test told me that the…

I want to know the Science behind Old salty: Dose age affect the ability to detect salt
Re: dose age affect the ability to detect salt
Hi Nate111,
Our ability to taste is due to taste buds covering our tongues; taste buds are receptors that transmit electrochemical signals to the brain, via sensory neurons, which allow us to taste certain flavors (or, in some cases, no flavors). As we age, a process…

Science Fair Project
Science Fair Project
Hi!
I need help. I was thinking of doing this science fair project:
https://www.sciencebuddies.org/science-fair-projects/project-ideas/BioMed_p011/medical-biotechnology/drug-target-accuracy
But, my teacher said it's more of a research project rather than inquiry, since I'm just researching the inforation on the data bases.
If there any way to make this an inquiry project?

The effect of coffee on yeast cell growth
The effect of coffee on yeast cell growth
Hello. I am designing and experiment for my IB biology class. My plan is to test the effect coffee on yeast cells. I will be using saccharomyces cerevisiae, HAO Strain, a, wild type in my experiment. I will measure the yeast cell growth using a spectrophotometer. During my experiment, I plant to calculate the yeast cell growth at different intervals (i.e. 0,2,4,6,8 hours). In order to this as accurately as…

Dead zones
Dead zones
Hi, I'm doing a science fair project on dead zones. I was wondering if it was feasible to find a way to effectively bring dead zones "back to life". Right now I'm debating on whether to gear my project towards an engineering one, or a research one. Any help would be appreciated, thanks!
Re: Dead zones
Hello,
This is a really interesting project idea! It's definitely possible to come up with a hands on experiment to explore this question. The first step in planning…
