Study Guide
Parts of a Plant
Test date:
Below are listed the jobs or functions of each of the parts of a plant.
The flower:
1. attracts insects or birds that will carry pollen
2. makes seeds
The leaf:
1. takes in carbon dioxide and releases oxygen
2. works with the sun to make food for the plant
The stem:
1. Carries water from the roots to other parts of the plant
2. holds the leaves up to the light
The roots:
1. take up water and minerals from the soil
2. hold the plant in the soil
The fruit:
1. contains the seeds
The seeds:
1. make new plants
11/9 The students will begin to learn the six plants of a plants and their
jobs or functions.
10/23 We will begun to learn about plants, how they germinate, and two types
of seeds - monocot(example:corn seed) and dicot(example - lima bean seed).
*****************************************************************************
Our third grade class will be using an exciting science program called
Science 21, which is activity-based and NOT textbook-based. Research has
shown that true science
learning does not come from memorizing facts from a
science textbook. Rather, good science is learned through active
participation, engaging students in inquiry-based, hands-on experiences.
Through Science 21 your child will be actively engaged in science
activities,
learning how scientists as questions and design experiments to find the
answers. Like scientists, your child will be working cooperatively recording
results, and sharing them with the rest of the class.
Cycles In the Natural World
The Grade 3 curriculum is the Science 21 Program developed at the
Putnam/Northern Westchester
BOCES. The Program was put together by area elementary teachers to provide
direction and vision
of elementary science education for local school districts. The program’s
main focus is a hands-
on, inquiry-based science, and that math, language arts and technology are
integrated at points
where they fit naturally.
Content and Core Lesson is divided into four units:
Unit 1: How a Scientist Investigates Plant Cycles
• What a scientist does
• How a scientist (student) keeps an account of their work
• Investigate how a seed becomes a plant
• Parts and functions of a plant
Unit 2: How a Scientist Investigates Electricity
• Introduction to electricity
• How switches control the flow of electricity
• Conductors and non-conductors
• Series and parallel circuits
• Creating a circuit board
Unit 3: How a Scientist Investigates Water Cycles
• Sources and types of water
• States of water
• Water cycle
• Weather and the water cycle
• Conservation of water
Unit 4: How a Scientist Investigates Animal Cycles
• Study and observe the butterfly
