Vernal Pools and Amphibian Survival
Written by Adi Ackerman, Head Teacher
"Vernal Pools and Amphibian Survival" is written for 7th Grade (Ages 12-13), and it covers NGSS MS-LS2-4. A 6th grader who is already steady on ecosystems can use it too, and an older student can use it as a short review.

7th grade science worksheet: make a scatter plot of weeks a vernal pool held water against wood frog metamorphs and explain it. Answer key included. Part of our populations and invasive species ecosystems collection. Aligned to NGSS standards.
How do I use this worksheet?
Start with the growth rate calculations, then use the vernal pool sheet for data analysis and the cane toad organizer for reading and summarizing.
What students will practice
- Students will plot weeks of water against wood frog metamorphs as a scatter plot.
- Students will describe the pattern and use numbers from the table to support it.
- Students will explain why no metamorphs survive when a pool dries too early.

FAQ
How do I use this populations and invasive species worksheet?
⌄
Start with the growth rate calculations, then use the vernal pool sheet for data analysis and the cane toad organizer for reading and summarizing.
What does this worksheet teach?
⌄
Make a scatter plot of weeks a vernal pool held water against wood frog metamorphs and explain it. The directions on the page read: Read the text and study the table. Then make the scatter plot and answer the questions on page 2. An answer key is included.
Can I use this populations and invasive species worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade ecosystems, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What is carrying capacity?
⌄
It is the largest population an environment can support. Logistic growth is an S curve that levels off near it.
What is exponential growth?
⌄
It is a J curve that speeds up with nothing to limit it.
Why did cane toads spread in Australia?
⌄
About 100 toads were shipped to Queensland in June 1935 to fight beetles in sugar cane. They bred and spread, and the organizer asks students to record why.
