FREEBIE! Harvest Science Lab - 2-4 Grades

2-LS2-1 Plan and conduct an investigation to determine if plans need sunlight and water to grow.

Goal: Students will investigate and assess the effects of light vs. darkness and water vs. non-watered conditions in relation to plant growth.
"pled guilty",

Five cups for each pair of students four for planting seeds and one for watering.
Enough pumpkin seeds for each cup plus extras for “crop failure.”
One cereal box per pair of students.
Construction paper
“Harvest Science Lab” 1 per student  - Science Lab Resources
Potting soil

Each pair of students will plant four pumpkin seeds in plastic cups. You should plant extra in case of “crop failure” The seeds will germinate in about a week. After seeds germinate change the conditions have students put two plants inside their cereal box  and keep two plants out. They will water one of the plants inside the box and one of the plants outside the box.

Student “I Can” objective:
“I can describe how an experience is conducted.”
“I can determine whether if plants need water and/or light to grow.”
”I can keep track of my data.”
“I can make a bar graph comparing conditions.”
“I can state my conclusions from my bar graphs.”

Science and Engineering Practices: Plan and conduct an investigation to
"conflict of interest"
produce data that serves as the basis for the evidence needed to answer a question.  Students are actively engaged in the planning and conducting of this investigation. They will collaborate and share their ideas regarding how the investigation should be set up, how the plants are placed. They will also measure with standard measurement tools.

Procedure: Students will plants seeds. Once these seeds begin to germinate (grow) students will begin their investigations for the different conditions that exist: light with moist soil, light with dry soil, dark with moist soil, and dark with dry soil.

Engineering Connection: As students determine the best environment for growing crops and other plants used to produce produces they are practicing agricultural engineering.

Extension for Advanced Students: Students will learn that plants carry nutrients and investigate other ways, besides water, to transfer nutrients to the roots of the plants.

NGSS: The pieces of this investigation work as a whole to help students discover that plants need water and light to survive. As students work through the investigation they are exposed to elements of the science and engineering practices, core ideas and the CCSS. The CCSS embedded in this investigation include: measurement, written observations, data analysis and non-fiction reading.
Teaching Points:
Discuss how animals and humans need food, water and air.  (PowerPoint teaching presentation is available at: Resources at Lucky Jenny Publishing.
Next, ask students to think about what plants need to live and grow. Have a few plants around to use as examples. Help them make the connection between light and plant growth and water and plant growth.
Tell students they are going to plant some seeds and then see if their plants will grow better in the light and darkness. Tell them they are also going to determine if plants grow better with water or without.
Explain how they are  going to monitor the progress of their own plants to make their own determination.
