1. SCIENCE 4 Using Weather Instruments QUARTER 4 WEEK 4 DAY 1

2. Drill/Review Draw a line to match the weather instrument to its use on the right.

3. Motivation What is the weather today? Identify the weather symbol below. Choose your answer inside the box.

4. Presentation Do the Activity: Activity Creating an Improvised Anemometer . Materials: 4 plastic cups of the same color, 1 plastic cup of a different color, 2 long strips of stiff cardboard, pen, pencil with an eraser on one end, ruler, stapler, push pin, watch with a second hand or timer, small fan and calculator

5. Presentation Procedures: 1. Place the cardboard strips on top of each other to form a plus sign. Then, use the stapler to staple them together. Staple them in the center of the plus sign so they hold their shape. 2. Attach 4 cups to the ends of the cardboard pieces. Use the different colored cup as one of the 4 cups. Staple the cups onto the cardboard so they are on their sides, facing the same direction in relation to the cardboard pieces.

6. Presentation 3. Place the pushpin through the center of the cardboard pieces. Then, push the eraser part of the pencil into the pin sticking out of the center of the cardboard pieces. • Use the scissors to poke a small hole in the bottom of the remaining cup. Slide the pencil into this cup. • The anemometer should now stand upright, supported by the pencil in the cup. There should be 4 cups on the ends of the cardboard pieces, all on their sides and facing the same way.

7. Presentation 4. If you have a small fan available, set it up several feet away from the anemometer and turn it on to a low speed. Using the stopwatch, count the number of rotations in 15 seconds and multiply this number by 4 to get the number of rotations per minute.

8. Presentation In 15 seconds, how many number of rotations your improvised wind vane has created?
