PLANT GROWTH and DEVELOPMENT

(based on STC Kit)

 

INTRODUCTION

Plants are organisms that can reproduce and survive if they live in environments that meet their basic needs.  Plants need to find ways to obtain water, air, nutrients and protection in the areas in which they live.  Some plants live on land and others live in water.  Sometimes, plants can adapt to their environments in order to find survival.  Understanding how plants survive can help us gain a greater understanding of living things.

 

 

SCIENCE STANDARDS AND INDICATORS

 

Content Standard 2.2:   Plants change their forms as part of their life cycles.

A19  Describe the life cycles of flowering plants as they grow from seeds, proceed through maturation and produce new seeds.

A20 Explore and describe the effects of light and water on seed germination and plant growth.

 

Content Standard 3.2:  Organisms can survive and reproduce only in environments that meet their basic needs.

 

B3:  Describe how different plants and animals are adapted to obtain air, water, food and protection in specific land habitats.

 

B4:  Describe how different plants and animals are adapted to obtain water, food and protection in water habitats.

 

SCIENCE INQUIRY: Scientific inquiry is a thoughtful and coordinated attempt to search out describe, explain and predict natural phenomena.

 

SCIENCE LITERACY: Science literacy includes speaking listening, presenting, interpreting, reading and writing about science.

 

SCIENCE NUMERACY: Mathematics provides useful tool for the description, analysis and presentation of scientific data and ideas.

 

EXPECTED PERFORMANCES

BINQ.1  Make observations and ask questions about objects, organisms and the environment.

BINQ.4  Employ simple equipment and measuring tools to gather data and extend the senses. 

BINQ.6  Analyze, critique and communicate investigations using words, graphs and drawings. 

BINQ.9   Use mathematics to analyze, interpret and present data.

 

BIG IDEA  Plants survive and thrive in environments in which their basic needs are met.

 

Key Vocabulary:  environment, spines, thorns, toxins, needle, adaptations, stems, leaves, roots, pollination, fertilize, pollen

 

LINKS TO OTHER STANDARDS

MATH

4.1.a   Design surveys for the collection of data and justify conclusions drawn from the data.

4.2.a   Analyze data to identify a typical element or event.

4.3.a   Use samples and simulations to determine probability, and to make and test predictions.

·       Students count the seeds and compare that number with the original number of seeds planted (8) to determine their profit or loss.

Students think about additional questions they have about plants and experiments that might help answer them.
