Experiments with Weather-Makers - Purdue Extension
Experiments with Weather-Makers
General Objective: Learn basic weather concepts through hands on discovery and observation.
Specific Objectives: Discover:
• how the sun heats,
• that air takes up space,
• what causes air to move,
• about air density,
• that there is water in air, and
• how temperature can vary (microclimates).
Time: Two one hour sessions
Resources needed: 4-H 346, copies of pp 3-7, enlarged if possible. Cut pages so each experiment coordinates with the listed stations. Make copies of the Weather Worksheet so each team will have one. Set up stations with the following supplies.
|Day/Week 1 |
|Station 1: Sun |Station 2: Air (space) |
|Flashlight |Bowl or pan partly filled with water |
|Piece of grid paper |Drinking glass |
|A pencil | |
|Station 3: Air (movement) |Station 4: Air (weight) |
|Yardstick |Yardstick or similar |
|Two paper sacks |Two rubber bands |
|Masking tape or thumb tacks |Two balloons |
|Lamp |One empty milk or juice carton |
|Chair | |
|Day/Week 2 |
|Station 5: Water (evaporation) |Station 6: Water (fog) |
|Two saucers |Bottle |
|Spoon |Water |
|Water |Ice cube (will need multiple for subsequent groups) |
|Station 7: Water (rain) |Station 8: Earth |
|Metal pan |Thermometer |
|Ice cubes |Cup |
|Tea kettle and hot plate |Dish or pan |
|Water |Clock or watch |
|Plate or pan |Light and dark soil |
Activity: Collect the materials and set up four stations (or have the kids help set them up) on each day you do the weather activities. Each station should have the materials listed and a copy (or copies) of the instructions from 4-H 346.
Discussion – 10 minutes:
• Before you start, ask the students: What makes our weather?
Answers: Sun, Air, Water, Earth
• Explain that they will do experiments and learn about what makes weather.
• Divide the students into 4 groups. Assign one reader, two students to do the activity, and one recorder for the first station. Tell the students that they need to switch roles at each new station so everyone gets a chance to do all jobs.
• It is best if all the students have jobs so adjust (more stations or 2 groups at each station with separate materials) for classes larger than 16.
• Briefly explain what will happen at each station. The first recorder should pick up a Weather Worksheet and put their team number and names one it. Then the team works together to read (the reader), do the experiment (scientists), and answer the questions (all – with the recorder writing the answers).
Experiments – 50 minutes:
• Assign the station where each group will start and explain that they will have 10 minutes to do the experiment, write down their observations, and answer any questions in the instructions.
• Educators walk around to help and observe how the students are doing.
• After 10 minutes move to the next station and change roles.
• After all 8 stations have been completed have each group write their conclusions.
