Stingray Growth Project

I had been wanting to introduce measurement and charting to my little man but wanted a way to engage him and keep it both project based and hands on. It was on a visit to the local dollar store that Chandler answered the question for me. He found a stingray and showed it to me. What he didn't realize is that it was one of the grow-in-water toys. So we spent the dollar and home we returned to discover what would happen to this little stingray as we exposed him to water.

1 - Trace a grow in water animal.
2- Measure it with yarn.
3- Cut the yarn to the same length.
4- Measure the string 
5- Document the length.
6- Put in water for 3 days
7 - Repeat process
8- Document growth.

Skill sets: Measuring, Science, Scissor skills, Glue skills, Charting, Observation

Cost: $1.00

Tracing the original stingray before we put it in the water.

Measure and cut yard the length of the stingray.

Apply glue for our yarn

Glue yarn

Measure the yarn and document the findings.

Put the stingray into a bath or shoebox of water. Make sure it has room to grow.

Three days later we traced the grown stingray, and measured the yarn again.

It has grown!

Every scientist must document their discoveries!

Finished project!
