• 1 to 7

• 0 to 6

• 2 to 8

How can you test whether a substance is acidic or basic using indicators?

• Mix with water, observe color change: red/orange/yellow (acidic) or green/blue/purple (basic)

• Add sugar to substance, observe color change: red/orange/yellow (acidic) or green/blue/purple (basic)

• Add indicator to substance, observe color change: red/orange/yellow (acidic) or green/blue/purple (basic)

• Photosynthesis

What are the circular wind patterns that form in the atmosphere due to the Earth's rotation called?

• Jet streams

• Trade winds

• Tornadoes

• Coriolis effect

Explain how storms and cyclones are formed in the atmosphere.

• Cold air rising instead of warm air

• High pressure area created instead of low pressure

• No moisture condensing

• Warm air rising, moisture condensing, Coriolis effect causing air to spin, low pressure area created, surrounding air rushes in, spiraling motion intensifies into a storm or cyclone.

What safety measures should be taken during extreme weather conditions like hurricanes and tornadoes?

• Drive around to see the damage

• Stand outside to watch the storm

• Seek shelter in a sturdy building, stay away from windows, secure loose outdoor items, have an emergency kit, and follow evacuation orders if necessary.

• Ignore evacuation orders and stay home
