Microbes Science Project for Kids

Updated on November 24, 2008

This is an overview of a microbes science project for kids provided by Heath Scientific. All materials needed to conduct this experiment can be purchased from Heath Scientific.

The Unseen World Kit is a science project designed to teach children about microbes growing in the world as well as to introduce the concepts of microbes and bacteria in a fun and interesting way, allowing parents to take a more active role in their child’s education.

General Overview

Also known as microorganisms, microbes are tiny, microscopic organisms found throughout life. Some microbes are disease-causing bacteria. Bacteria can be found everywhere, including throughout a home, in a number of places, from the bathroom to the kitchen.

The purpose of this science project is to allow children to “catch and grow” microbes, including some bacteria, and observe them in a controlled environment to understand how bacteria can be found almost anywhere.

Identifying Bacteria

Shape- Rods, Spheres, and Spirals

Gram Stain- Positive (+) or negative (-)

Habitat- With or without oxygen, hot or cold, dark or light, salty or not

Movement- Motile or non-motile

Color- White, Yellow, Pink, Purple

Supplies Needed

1 bottle of nutrient agar

1 sleeve of 10 petri dishes

10 sterile swabs

Experiment Procedure

The bacteria experiment is conducted as follows. The bottle of agar is placed in a saucepan, which is filled up to a depth equal to half the height of the bottle. The cap of the bottle is loosened but not removed and the water is heated until boiling. The agar bottle is removed when all the agar has melted. The agar is poured into the petri dish until three-fourths of the bottom of the dish is covered. The lid is replaced over the dish and the agar is swirled to cover the bottom of the dish. Now the agar and petri dishes are ready.

There are a number of different experiments that can be conducted in this science project. Simply swipe the sterile swabs over a surface to be tested for microbes and bacteria then gently swipe the swab over the bottom surface of the petri dish before replacing the lid. After an incubation time that lasts one to three days, bacteria will begin to grow, which will appear as fungi in the petri dish.

This bacteria experiment allows homeschooling parents to easily explain the concepts of microbes and bacteria without a large investment.

Science project kits such as the bacteria experiment are available from Heath Scientific’s website. These science projects cover a wide range of topics from microbes to density to electricity. They offer a relatively inexpensive way for home schooling parents to enhance their child’s education. Additionally, they offer an easy way for parents to improve their home school curriculum as well take an active role in their child’s education by working the experiments alongside their child.

Caution

To avoid contamination, it is extremely important that after the petri dishes have been inoculated with microbes and bacteria that they are not opened again. To avoid contamination, tape the lid shut. After the experiment, used petri dishes can be thrown away in a dumpster or with the regular trash.

      Probiotics are live microorganisms thought to be healthy for the host organism. According to the currently adopted definition by FAO/WHO, probiotics are: "Live microorganisms which when administered in adequate amounts confer a health benefit on the host". A leading medical group says there's some evidence that probiotics, or "good" bacteria, may have limited benefits for certain illnesses in children.

      But the group says the science isn't yet strong enough to advocate infant formulas containing probiotics. And probiotics shouldn't be given to children who are seriously ill.

      That's according to a new American Academy of Pediatrics report published Monday in the journal.

      this is very important
