Well, after watching the experiment conducted by NASA, what can you infer about it? What did you feel while watching the video?
This time, IT'S YOUR TURN! You will act like them, as if you are a professional one!
"How?"
Simple! By conducting your own and actual experiment! Below is the activity 1 that you will be conducting and included there are the materials as well as the step-by-step procedure to guide you. Please observe safety precautions in performing the activity. Nonetheless, MAKE LEARNING FUN AND PRODUCTIVE!
GOOD LUCK future scientist/science connoisseur!
ACTIVITY 1
What happens when a comet or an asteroid hits the Earth?
MATERIALS NEEDED:
-
1 rectangular container (aluminum tray or plastic)
-
1 pebble (1-4 cm in diameter)
-
Colored flour/ colored starch
-
Pencil
PROCEDURE:
-
Fill the rectangular tray with colored flour/colored starch about 3-4 cm deep.
-
Place the tray on top of a table (or armrest of a chair).
-
Throw a pebble to hit the flour in the tray. Do this about four times, hitting different parts of the flour in the tray.
-
Observe the craters made by the pebbles on the colored flour/colored starch.
-
Compare what you have observed with the shape of the impact crater as shown in the photo below:
Answer the following questions:
-
What do you notice about the shape of your pebbles’ crater and the shape of the impact crater shown in the photo?
-
What do you think happened to the plants and animals living in the area where the comet or asteroid crashed?
