Bubble Experiment (For Kids)

Hey and welcome to Science. Today you are going to do a bubble lab. Make bubbles, sounds interesting? Hope so! So in this lab we are going to measure the diameter of bubbles blown. We will have one independent variable, the number of straws. So lets get started!!!

 Materials needed: froggy soap (aloa vera) 

                             destilled water

                             beaker

                             graduaded cylinder

                             pipet

                             lab table/ flat surface

                             meter stick

                            paper/pencil

                            3 different people

                            5 mm straws

                            graph paper

                            paper towel

                                                                 Method

1. Take 100 ml distilled water in the graduaded cylinder and then pour it into the beaker.

2. Now use the pipet and take 2 ml of froggy soap

3. Put it into the Beaker and stir for 15 seconds with a stirring machine or the pipet

4. Now take 1 paper towel and dip it into the soap mixture

5. Flaten it out on the surface and cover about 60 x 60 cm of the surface

6. Now blow with the straw on the table. A bubble should form.

7. Once the bubble breakes or pops you have to take the ruler and measure the diameter.

8. Now put this info into a data table.

9. Now you sweep off the total mixture and you restart step 1-5

10. Now you use instead of only 1 straw, 2 straws. Blow at the same time and wait until pops.

11. Now do step 7-8 and repeat 1-8 with the changing of the amount of straws until you have enough data to make a graph.

12. Now do a lab report. Done!!!
