Humans live and cannot live without oxygen because we need to breathe clean air to stay healthy. But bad air quality can also lead to breathing problems with allergies and asthma, so how do you test the air quality around your children's living environment? Today, the alpha science classroom is exploring the mystery of air quality with children through the Air Quality Experiment for Kids. The materials needed for this children's environmental science experiment are available at home, and parents can try this kid's science experiments activity with their children to show them that there are things in the air that we can't see and to unlock the mysteries of nature.
Alpha Science Classroom: Air Quality Experiment for Kids, Materials Required
3 index cards
Graph paper (or use a pencil and ruler to draw a grid on each index card)
Butter knife or plastic knife
String or fishing line
Alpha Science Classroom： Air Quality Experiment for Kids, process
Step 1: First, children trim each piece of graph paper into a 10 x 10 square grid of equal area. If your squares are large and the 10 x 10 grid does not fit on your index card, you may need to use a 5 x 5 square area instead. If you don't have graph paper, you may want to use a ruler and pencil to draw a grid neatly on each index card. It is important that the grid is the same size on each card so that you can compare the results later. Finally, apply glue to the grid paper on white paper.
Step 2: Children once your grid is trimmed, glue one to each index card and let the glue dry, three pieces of paper with grid paper and location labels.
Step 3: Children put numbers and location labels on each card. You may want to write "Science experiment in progress, do not touch" on the index cards so no one takes them away, then use a butter knife to apply Vaseline to the grid paper.
Step 4: Children use a butter knife to apply an even layer of Vaseline and cover the entire area of the grid, then hang pieces of paper from the grid paper and Vaseline with string, and finally children tie a string to each index card and tie it to the paper and grid paper on the kitchen wall.
Step 5: Children use the string to hang the index cards in different locations in and around the house. If you are hanging the cards on a branch or any other hard-to-reach place, ask an adult to help.
Step 6: This process requires the children to wait 5 days for the particles to settle on the Vaseline. Check the weather each morning. If it's going to rain, you may need to end the experiment early so the cards don't get wet As long as the cards hang for at least 24 hours, then this children's environmental science experiment should still work, but it works best if you let them sit for 5 days. Depending on the weather and your schedule, choose a time frame that works best for you, then place a piece of paper with three square grids glued to it next to a pencil.
Step 7: Children create a table for each index card to record their results. The table should have the same number of squares as the grid on the index card (see example on the left), then glue a piece of paper with three squares on it and write a record of the experiment.
Step 8: Children collect the cards and use a magnifying glass to count the number of particles found in each square on each index card. Record your results in the squares of the data table. Children use a magnifying glass to look at the particles in Vaseline on the square of paper and then have a written record of the experiment on the square of paper
Step 9: For each index card, children need to calculate the average number of particles found in each square. Do this by adding up the total number of particles found on the card and dividing by the number of squares (e.g., if you made a 5 x 5 square grid, you would divide by 25).
Through this fun kid's science experiments, Alpha Science Classroom wants to show children that there are many tiny particles in the air we breathe. Some of them are naturally occurring, such as pollen, dust, hair, and dirt, while others come from man-made sources, such as factories, power plants, and cars. If we all choose to use more clean energy and transportation, we'll have cleaner air to breathe. Instead of gas and coal, which emit pollutants, people can use solar, wind, and hydroelectric power, which are considered "clean energy".
Air quality is very important to us. After this children's environmental science popularization experiment activity, the children also understood the surrounding environment of their lives, so living in an environment with poor air quality, masks are very important protective tools, especially Time is especially important in this special environment. Let children understand the impact of air and environment on human health, better protect themselves, and grow up healthily and happily.
Alpha science toys have also created an environmental science experiment kit for children to help them understand the environment, explore the scientific mysteries and become the most powerful environmentalist.
