In this lesson, students learn about science experiments, design and execute an experiment to learn about what plants need to survive, and communicate their findings to others.
Step 1 - Inquire: Students observe the differences between freshwater, brackish water, and saltwater in order to make predictions about what plants need to survive.
Step 2 - Investigate: Students design and carry out an experiment to test their predictions about what plants need to survive.
Step 3 - Inspire: Students use their findings to add information to their art project.
Students engage in many of the Next Generation Science Standards Science and Engineering Practices.
Students have the opportunity to develop and execute an experiment.
Students use both sketching and writing as observational tools.
This is lesson 3 of 4 in our K-2nd grade Water and Plant Survival unit.
You will need the following materials for activity in the Inquire section:
1-liter pitcher of plain water
1-liter pitcher of water with about 2 teaspoons of salt dissolved
1-liter pitcher of water with about 6 teaspoons of salt dissolved
A small cup for each student
You will need the following materials for the pre-filled experiment in the Investigate section:
3-6 plants (choose one type of plant, 1-2 plants will receive freshwater, 1-2 plants will receive brackish water, and 1-2 plants will receive saltwater)
A measuring cup
A sunny location
You can choose the scientist video in the Investigate section that is the best fit for your students. Options include Sesame Street: Bouncing Balls or A Study in Stream Ecology. The Teacher Slideshow includes slides with questions specific to each video.
The Investigate section offers several options for experimentation. Each option will provide students with the understanding needed to complete subsequent lessons in the unit. The three options include:
Students may create their own experiment, with teacher support.
Students may participate in an experiment where the procedure is provided.
Students can look at data collected from an experiment and discuss the findings.
The lesson allows students to use scientific method to inquire about how different plants can survive across fresh water, salt water, and brackish water. It allows students to investigate the changes and predict the water conditions required for plants to survive. All images, videos, and accompanying materials featured in the lesson have been reviewed. This lesson has passed our science review process.

Salt and Plants (Water and Plant Survival #4)
In this lesson, students reflect on how salt affects plants, learn how some communities are finding ways to grow plants in saltier conditions, and create a mural to share their learning with the community.
