Purpose of DASH

• Climate Education• For Grades 3& 4

Contents of DASH• Weather• Wind• Rain• Temperature• Clouds• Monthly Weather Summary• Severe Weather• Introduction to Climate• From Islands to Atolls• Water Cycle• Erosion• Human Impacts• Year End Weather Summary• Concept and Skill Inventory

DASH Components

Inventor’s Box• Storage technique

Concept Maps

1. Assess students’ prior knowledge of the topic.2. Summarize, organize, and assess ongoing learning about the topic.3. Assess class knowledge of the topic.

Activity: Work in small groups to make concept maps about weather.• STUDENT ROLE• Meteorologist

• MATERIALS• chart paper• markers

Example of Concept Map

Weather

sunny stormy

thermometer

cold

hot

snowy

foggy

cloudy

windy

Example of a working definition

• A refrigerator is an appliance used for keeping things cold and making ice. It is usually box-shaped, comes in many colors, has a door with a handle and shelves, and needs electricity to operate.

Activity: Working Definition of Weather

• Meteorologist

• MATERIALS• chart paper• markers

Responsibility Chart•Assign classroom jobs and responsibilities

Science Record Book

• Store student’s notes, data, plans and other work

SRB

Wonder and Discovery Book

• Record student’s questions Wonder and DiscoverBook???

W & DBook

Connections and Reflections

• Reflect on their learning in science and to look for connections, relationships and application

C & RBook

DASH Contents

CloudsOBJECTIVES•Identify stratus and cumulus clouds.•Estimate and record the daily amount of cloud cover.•Hypothesize about temperature in a cloud’s shadow and in sunlight.•Measure temperatures under cloud cover and in sunlight.•Make hypotheses and generalizations about temperature and cloud cover.

From Islands To Atolls(Island Formation)

Grouping

• Children learn more from each other• Develop social skills needed• Built self-esteem

Why do it?

Some ideas on group sizes

• Pairs: For most interactions• 2-3: For problem solving projects• 4-6: For big projects• Class: To give directions

Let’s try some hands-on activities

Temperature

• Why is temperature important?• What does temperature mean?• What do you know about temperature?

Strategies for this lesson

• Concept mapping • Collect data • Record data • Working definition

Materials

• Thermometer • Poster • Markers • Daily Temperature data sheet

Let’s try

• Get into a group • Get your group materials• Work together (Brainstorm and create concept map)

Thermometer

Daily Temperature Data Collection

DateTemperature 1 Comments

Time °C °F

Meteorologist(s)

Group work

Get a thermometer Record this room temperature (measure and record °C and °F)Record outside temperature (measure and record °C and °F)

COMPARE THEM WITH OTHER GROUP DATA THEY HAVE COLLECTED

WORKING DEFINITION

• WHAT YOU TRULY KNOW ABOUT TEMPERATURE??

Water Cycle Game with Lucy

      

GAME DIRECTIONS 

PLAYERS2–4 players1 judge

 MATERIALS PER GROUPS

colored game marker for each playerone diegame boardset of question cards

 RULES

1. Each player chooses a colored marker and places it near START on the game board.2. Each player rolls the die. The player rolling the highest number goes first. Players take turns, rotating clockwise

around the group.3. Each player in turn rolls the die. The number on the die indicates the number of spaces the player may move.4. HOWEVER, before a player moves, the judge will draw a question card from the deck and ask the question of the

player. If the answer is correct, the player may move the number of spaces shown on the die. If the answer is incorrect, the player must remain on the same space until the next turn.THE JUDGE’S DECISIONS ARE FINAL.

5. If a player lands on one of the special spaces (see game board), the player must follow the directions given on the game board for that space.

6. The winning team is the first one to have all their groups players reach FINISH.

That’s All For Today
