Development of Super absorbent polymer Development of Super absorbent polymer I am an incoming Grade 11 student here in the Philippines, and I am trying to conduct a research study influenced by Kiara Nirghin's development of Super absorbent polymer using Orange and Avocado peels. But, in our study we are trying to change the variables ---- Orange and Avocado peels to Calamansi and Mung Bean wastes which are way more abundant and accessible in our country. But when we tried developing our own… Read more
Help with my project/bacteria Help with my project/bacteria For my project I plan on conducting a research where I find the inhibition potencies of garlic verses the synthetically manufactured antibiotics I chose, gentamicin and penicillin, and seeing how they affect the gut microbiome by testing them on E. coli and Bifidobacterium animalis subspecies lactis. I was going to purchase my Bifidobacterium animalis subspecies lactis bacterium from atcc, although it seems to be very expensive. I… Read more

Put these steps in chronological order Put these steps in chronological order Observation: We brought a block of unsliced cheese on the same day, and it isn't moldy at all. Hypothesis: I think that sliced cheese gets moldy faster because people touch it more. Results: After five days, both sets of cheese that I touched are moldy. Both sets of cheese that I left alone have no mold. Experiment: I keep four separate sets of cheese in the refrigerator: five slices that I touch once a day; five… Read more

Finding data for neutralization experiment. Finding data for neutralization experiment. Hi, For a depth study I am conducting an experiment to test which base is most effective at neutralizing a range of acids (about 3). However I am having trouble coming up with a variable to measure, at the moment my experiment consists of measuring the pH before and after neutralization reaction to see which would be closest to neutral (7). However both me and my teacher think there could be a better… Read more
Different methods of sanitization Different methods of sanitization I would like to do an experiment testing the effectiveness of different disinfectant methods. For example hand sanitizer, regular soap, antibacterial soap, scented soap, UVC, Lysol, Clorox, bleach, Iodine, etc. Would it be more beneficial to use a specific strain of bacteria or simply do a general swab? I would like this to simulate a real-world scenario. I would also like to make the project more complex if possible. I am… Read more
Gel electrophoresis and PCR Gel electrophoresis and PCR Does anyone have any ideas on how I could incorporate gel electrophoresis and PCR into my science fair project? Thank you in advance Re: Gel electrophoresis and PCR Hi dominiqueolivia, Do you already have a project in mind? If not, I recommend looking through the Science Buddies Project Ideas pages and searching for either PCR or gel electrophoresis. I did not click through all of the options, but I did find this project idea that… Read more
Spatial Modeling Spatial Modeling For this year's science fair project, I wanted to look into creating a spatial model to represent the spread of COVID-19 right now as compared to the months following a vaccine. How would I create a spatial model and how would I incorporate various prevention measures? Thank you in advance! Re: Spatial Modeling I know there was a project done at ISEF a few years ago utilizing a gravity spacial model for the Ebola outbreak in West Africa. I would like to… Read more
Question That My Teacher Couldn't Answer - Plants Question That My Teacher Couldn't Answer - Plants What are pith rays and vascular rays in plants? What are their differences and what are their jobs? Re: Question That My Teacher Couldn't Answer - Plants I'm not positive about this but I believe they are the same thing but in two different regions. The pith rays being in the pith of the plant and the vascular rays being further outward in the vascular cambium. Both act as "veins"… Read more
