What should you use to cover your eyes while doing an experiment?
Goggles

What is a force?
A push or a pull in one particular direction.

Give the physical properties of ice.
Ex: clear, smooth, cold, small, slippery, wet

What are 4 types of soil?
Gravel, humus, sand, clay
100
Weathering _____ it. Erosion _____ it. And when the motion stops, deposition _____.
Weathering breaks it. Erosion takes it. And when the motion stops, deposition drops.

During an investigation of heat energy, students are instructed to use safe practices. What is the importance of using safe practices during a lab investigation?
It is important so that we don't have any dangerous situations.

Name the 5 different types of a force.
push, pull, friction, gravity, magnetism.
200
Name the properties of gravel.
cold, grey/tan/white/black, large particles, smooth, bumpy, doesn't retain much water.
200
What happens to a rock with a crack in it, when water fills that crack and then freezes?
The rock will expand. over time, this will cause the rock to break.
300
Students are doing an experiment. About how many times should they do the experiment to make sure that their answers are accurate & not just a lucky try?
3 tries
300
A pencil falls to the ground when it is dropped. Which force acts upon the pencil, causing it to fall?
Gravity- Without gravity, it would float when dropped!
300
Two rocks were placed on a triple beam balance. The measurement for each rock was recorded at 16 grams. Each rock had the same_____.
mass.
300
Which type of soil will grow plants the best?
Humus
300
What is sand made up of?
It is made up of broken down shells & rocks that have been weathered down over time.
400
What is a hypothesis?
It is a prediction on what you believe will happen in a science experiment based off of your prior knowlegde
400
Students test the effects of friction on different surfaces. Which type of surface will increase the amount of friction? a) rough b) smooth c) wet d) slippery
a) rough
400
Which will not be attracted to a magnet? a) iron nail b) steel paper clip c) copper wire d) staple
c) copper wire- Even though copper is a metal, it is not magnetic. Pennies are made of copper and are not magnetic.
400
Student's use their sense of sight while studying sediments of soil types. Students are most likely studying the soil's- a) odor b) texture c) color d) flexibility
c) color- Odor uses smell, and texture & flexibility use touch.
400
Students write conclusions after studying changes to Earth's surface. Which student did NOT write an accurate conclusion? Student 1- Some changes to Earth's surface happen over a long period of time. Student 2- Erosion, deposition, and weathering are wars Earth's surface can be changed over a long period of time. Student 3- Water, wind and ice can change Earth's surface. Student 4- Changes to Earth's surface always happen quickly.
Student 4 because while some changes happen quickly, not all of them do. Weathering and erosion takes a very long time to occur.

What unit do we use to measure weight in science? length? volume? temperature?
grams, meters, liters, Celsius
500
What does a physical property tell you about an object?
It tells you what it is like on the outside. It tells you how hard an object is, how big or small it is, what it smells like, what color it is, what the texture of it it.
500
Why isn't clay the bets choice for growing plants?
It retains too much water. This causes the water to not be able to drain properly from the garden and will cause the plant to drown.

How do glaciers change the Earth's surface?
As they slowly move, they pick up dirt and rocks. These rocks them scrape away the surface that is underneath them. They leave a large U-shaped valley behind them.
