Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.
Masking tape Scissors If you do not have access to a school incubator you can make your own very easily, you will need: Refrigerate your Petri dishes containing the agar when you receive them.
Store them upside down. Make sure the cover is at the bottom and the agar media is on top. Gather all the materials you will need for this project.
These include the 10 Petri dishes, the plastic gloves, the sterile swabs, the bleach, the wax pencil, and the plastic bags to discard dirty swabs, the making tape and scissors. If you are not using the schools incubator, you will need the aquarium, the clear plastic, the tape, small lamp plus a 25 watt bulb and the Celsius thermometer Include a camera if you wish to take photos of the Petri dishes containing the bacterial colonies.
When ready to start the experiment, take the Petri dishes out of the refrigerator and let them come up to room temperature. This should take about an hour. Make 3 copies of the data chart provided below so that you may readily record your observations for each of the three days. Put on your apron, gloves and safety glasses.
Using the masking tape and your wax pencil, make labels for each room of the house in which you are going to test for bacterial growth. Also, make an equal number of labels with the word control.
Attach them to your Petri dishes. You now have an equal number of labels of the rooms you will check and a control for each one.
Now you are ready to go to each room in your house or apartment and place two Petri dishes in the middle of the room on the floor. Open one Petri dish exposing it to the air in the room and keep the other taped shut.
This other, the closed one is the control. Note, if you are testing 4 rooms, you have four open Petri dishes and 4 closed control Petri dishes.
Allow for an exposure period of one day Borrow an incubator from your school or construct your own by using the following directions provided in step 9. You will need it in step To make your instant incubator, take the aquarium and turn it so that the opening faces the front, not the top.
Use the heavy clear plastic to make a hanging door over the opening. Place the 75 watt bulb in the small lamp and place the lamp into the aquarium. Have the cord come out of the front.
Science Investigation Project GUIDELINES Charlotte Beach Science Investigation: Celebrating the ‘Messiness’ of Science Your investigation for this class is an opportunity to conduct an inquiry project into an authentic local problem. The driving question for your study is as follows. Ideas for Kids’ Science Projects. Suggestions for projects, how to conduct experiments and how to write a science report. Scientific investigation is the way in which scientists and researchers use a systematic approach to answer questions about the world around us.
Place the thermometer inside the aquarium so that you can readily read the temperature and do not need to move it. The temperature you need is 32 degrees or 90 degrees F. Now, put on your safely equipment, goggles, gloves and apron, close all of the open Petri dishes and seal them with masking tape.
Do the same with the controls. You may wish to take photos of all of them. Look closely at each one and record your observations on your data chart. Put all of the Petri dishes into the incubator.
Keep them there for 3 days. Each day observe and record your findings in your data chart. Take photos if you wish or draw sketches of the visible colonies. When you are ready to discard the Petri dishes use bleach on them and place them in plastic bags.
Have them soak in the bleach overnight and then discard.Crime Scene Investigation Foundations of Law Integrated Unit In this unit, students take on the role of crime scene investigators to solve a murder that has occurred at the school.
They will integrate math, science, and language arts into the s. Ideas for Kids’ Science Projects. Suggestions for projects, how to conduct experiments and how to write a science report.

Conducting science experiments isn't as hard as you think, the problem is often to come up with the idea for the project.
After you've conducted the experiment, you've still got to write a paper about the experiment afterward. Your Science Fair Project Question Once you have chosen a topic of interest, you will need to create a related scientific question. Without a good question, your whole science fair project .
