Rainbow Walking Water Science Experiment for Kids- paper towel science experiment prezi ,How this Science Experiment Works. The water moves up the paper towels through a process called capillary action. The paper towel is made from fibers and the water is able to travel through the gaps in the fibers. The gaps in the paper towel act like capillary tubes and pull the water upward.Fastest Way to Cool a Soda | Science project | EducationPlace your first can in the freezer. Wrap the wet paper towel around your second can and place it in the freezer. Place another can in the salted ice-water bath. Check the cans’ temperatures again after 5, 10, 15, and 20 minutes. Make sure to record the temperatures in your notebook each time. Plot your temperatures and times on graph paper.
This SWAY is a sample science fair project based on the classic elementary project: What is the best paper towel? Can a student use SWAY to present their science project (or any project for that matter)? The pictures/text and graphs here are samples and do not represent an actual project. However, you should look at it as a sample of what students COULD do to present their projects.
After reviewing some other literature in regards to the paper towel experiment, I found some different results. According to Consumer Reports (2009), Brawny was the most absorbent of all of the 21 brands that they tested. They found that Brawny held 2 ½ ounces more per square foot on average than the other brands tested.
towels in a time frame on one minute. In fact, Viva paper towel was most absorbent, Bounty the second most absorbent, and Magic as the third. Changes: Changes I would make to this experiment would be to test this experiment using more brands of paper towels, maybe three more.
This rainbow science experiment is as magic as the science behind it. The colored water travels up the paper towel by a process called capillary action. Capillary action is the ability of a liquid to flow upward, against gravity, in narrow spaces. This is the same thing that helps water climb from a plant’s roots to the leaves in the tree tops.
Limitations: Some of the limitations I encountered while going through with this experiment were the amount of water squeezed out of the paper towel and the amount of time the paper towel was given to absorb the water.When squeezing out the water from the different towel brands onto the 250 mL beaker, not of all the water is squeezed out some is still left either on the towel or your hand.
(Photo of experiment set up with paper towels dipped into nail polish remover/rubbing alcohol and leaf pieces, taped to a stick above the cups – note the darker liquid color because the leaves sat in the liquid overnight) If you’re continuing right now, or if it is the next day: carefully place a paper towel …

The paper towel lab for middle school is a classic science experiment that every teacher should use. Focusing on a product that every student can connect with, makes this an engaging science laboratory that kids can enjoy. In the process, kids naturally learn about variables, controls and key part
Science Behind the Paper Towel Rainbow. Similar to what we saw in the rainbow walking water experiment, the capillary action is what causes the water to move up the paper towel.. Water adheres to the walls of the small vessels in the paper towel, causing an upward force on the liquid at the edge.
Feb 19, 2010·Bean Plant Projects. A simple way to make a science fair project with paper towels involves lining a foam cup with a wet paper towel and slipping a lima bean (or other fast-growing seed) between the towel and the cup. You can make several of these seed-growers and test them under various conditions to see which one grows the best bean plant.
Dec 14, 2019·This activity can be used as an introduction to using the scientific method. It is relevant at all intermediate and high school levels( 6-12). Paper towels are used to introduce the basic steps of the scientific method and how it can be used to determine which type of paper towel is the most absorbent. Students will then use the scientific method to evaluate another property of the paper towel ...
