By now, you’ve probably heard of the water bottle flipping challenge. Children can spend countless hours tossing a water bottle in the air, attempting to make it land upright. This bottle flip math activity introduces young children to data analysis in a fun and easy way. Children will practice organizing, representing and interpreting the results from their bottle flip experiment.
This activity will help your child:
- Practice making predictions
- Collect, organize and interpret data
- Make a model to represent data
- Plastic water bottle
- Items to decorate your bottle (e.g. stickers, glitter, food coloring tabs)
- Marker or another writing utensil
- 20 blocks
1. Get creative! Decorate your plastic water bottle with stickers, glitter, food coloring tabs (to color the water), markers, or anything else you have around the house. Fill one-fourth of the bottle with water.
2. Create a tally chart to record your results. Draw a line down the center of the paper. On one side, write “Falls” and the other side “Stands.”
3. Ask your child to predict (or guess) how many times the bottle will stand and fall if you toss it 20 times. Dig a little deeper by asking questions such as: “Will the bottle stand or fall? How many times do you think it will fall or stand? Why do you think that?” Write down your predictions on your chart.
4. Start your experiment. Flip the bottle 20 times. After each bottle flip, make a tally mark in the “Stands” column if the bottle stands up when it lands or a tally mark in the “Falls” column if the bottle falls when it lands. You can group tallies by fives for easy counting.
5. Create a model of your results using blocks. Count out the number of blocks for the number of times the bottle fell, stack the blocks in a tower and set it on a flat surface or base plate. Count out the number of blocks for the number of times the bottle was able to stand, place the blocks in a tower and set it next to the other block tower. Label your block towers to make it easy to understand what each tower means.
6. Talk about the results with your child. Here are some questions you can ask: “Did the water bottle stand or fall more times? How can you tell? Which block tower has more? How many more?” Refer back to your predictions. “Did you guess how many times the bottle would stand correctly? Was your prediction close to the actual results?” Compare the block model and tally chart. “Does the block model show the same data as the tally chart?”
Keep the Conversation Going
Discuss with your child how else you could represent the data to show this information to others with questions like, “Could you draw pictures of the water bottle falling or standing? Could you use sticky notes or candy?”
