Given that my kids have an opportunity to enter a science fair at their school, we used this experiment as part of their project. Practicing good sanitation by keeping floors and surfaces clean is the most important lesson in all of this.
Here are some pointers for making sure you have a go.
5 second rule science fair project. Science fair projects are a great way to learn about the scientific method, experiment. Free shipping, cash on delivery available. Look for bacteria and record what you see.
Here are some pointers for making sure you have a go. Given that my kids have an opportunity to enter a science fair at their school, we used this experiment as part of their project. Place 6 grams (0.2 ounce) of agar powder in a clean glass or beaker and add 100 milliliters (3.4 ounces) of distilled water.
2.drop another piece of bread on the floor for one minute. Award winning science fair project: Take advantage of the natural curiosity of second graders with one of these ideas for science.
To find out if that’s true, we start with a hypothesis — a statement that can be tested. Food dropped on the ground for less than five seconds is not safe to eat as both research and my experiment show. Many of us follow this rule without knowing whether it is true and supported by scientific evidence, or whether it is just a myth passed down through generations.
This experiment is helpful to people because the ‘five second rule’ is incorrect and does not really work. I believe that if a food is dropped and lands on a dirty surface and is picked up in five seconds or less, then that food is contaminated, because foods that are dropped on a dirty surface for five seconds or less will have bacteria on them. Is it safe to eat something that has fallen on the floor, even if you pick it up within 5 seconds?
Stir the mix until the agar has dissolved completely. There are five main types of science fair projects: Microwave the mix on high until it comes to.
I predict that it is not safe to eat food off of the ground because there are germs and bacteria.

You will use agar plates to test if picking up fallen food from the ground in five seconds prevents the. Get the science behind the five second rule and learn how safe (or not) your home really is. Pick it up and put it under a well slide again for viewing under a microscope.
25 of the best 7th grade science projects and experiments. There are five main types of science fair projects: Put a fresh piece of , untouched bread under a well slide and view it under a microscope.
By sammy, anna and lucas My hypothesis was correct, food does get contaminated even when dropped on the floor for less than five seconds. Whether you are a parent trying to find the best project for your child's science fair, or a teacher putting together projects for this year these are all winners.
This experiment will evaluate whether there is any truth to this theory. Do it yourself (diy) by category of science. Record the amount of bacteria you see.
The following is the experiment that we used. Most everyone has heard of the five second rule, which says that a food is safe to eat after it's been dropped on the floor as long as you pick it up within 5 seconds. This video is about the 5 second rule.
Practicing good sanitation by keeping floors and surfaces clean is the most important lesson in all of this.
