Units 1 and 2
Johnny has black hair like his mom and a scar on his knee from falling off a slide.
Which of those traits is acquired ?
Evaporation
Condensation
Precipitation
Collection
I have 3 rocks (rock A is 60 grams, rock B is 50 grams, rock C is 55 grams). Which one will be deposited first?
Rock A, it is the most massive rock so it will deposit first
What kinds of things can cause water pollution?
Mining, Agriculture, Deforestation, Industry, Pollution (trash)
What percent of your brain is made of water?
75%!
I combined baking soda and vinegar and bubbles formed! What kind of reaction did I create?
A chemical reaction!
I brought a bag of strawberries to the beach (at 40ºF). I put them in 4 different containers. At the end of the day, I took the temperature of each. Which was the best insulator?
container 1: 55ºF, container 2: 62ºF, container 3: 51ºF, container 4: 53ºF
Container 2 because it gained the least heat energy. Insulators are meant to block the flow of heat energy, keeping cold things cold and hot things hot
At what speed do tropical storms become hurricanes?
74 mph!
A car slides down a ramp. First it slides down from the middle of the ramp. Then it slides down from the top of the ramp. Which position (middle or top) would cause the car to have the least speed and go the least distance?
The middle.
How many brains does an octopus have?
9!
My mom and dad have green eyes. What colored eyes do I have?
How do you know?
Green! I inherited the traits of my parents
I have 2 different boxes I want to send an ice cream cake in. Box A has a surface area of 20 inches. Box B has a surface area of 30 inches. Which box would help my ice cream cake stay frozen?
Box A because it has the smallest surface area. Smaller surface areas allow for less heat energy to flow
Is this chemical or mechanical weathering? How do you know?
"Wind slowly carved away the nose of a stone statue"
It's mechanical, there was no color change. Natural forces broke stone into sediment.
Lucas is standing still on the top of a slide. Does he have potential or kinetic energy? How do you know?
Potential, he is not moving!
What is the most common bird in the world?
Chickens
I combine 5 grams of alkaseltxer with 50 grams of water. What is the mass of my final product? And why?
55 grams because mass can never be created or destroyed.
Here's the weather report for the day:
- 23ºF, 2 mph wind, sunny
What kind of precipitation will fall?
None! there are no clouds.
Two places, Ecuador and Ireland, are on hurricane watch. Ecuador is on the equator. Ireland is 400 miles away. Which location will experience more of an impact from the hurricane? How do you know?
Ecuador, hurricanes form and are strongest near the equator.
I tested my electric slide on four surfaces. Below is how far I went.
Carpet: 5 meters, Wood: 8 meters, Ice: 10 meters, Dirt: 3 meters.
Which surface had the most friction? How do you know?
Dirt had the most friction. Friction opposes motion, so a surface with more friction will make objects travel less far
Roughly how many licks does it take to eat a standard scoop of ice cream?
50!
Julia combined soap, glue, and beads to make her special slime. Is this reaction reversible? How do you know?
It's irreversible because it's a chemical reaction, we can't bring the ingredients back to their original forms
- copper wire: 60ºF, silver wire 71ºF, gold wire 50ºF
You should use the silver wire, it's the best conductor and allows the most heat energy to flow?
This sentence is an example of what force?
"small pieces of rock were blown by the wind"
Wind Erosion! When wind moves sediment to a new locaiton.
Ball A collides with Ball B. Ball B then collides with Ball C. Ball C then collides with Ball D. Where is the kinetic energy in Ball D from?
Ball A
What is my favorite kind of candy?
PEANUT M&M'S!
