Life Science
What organ pumps blood throughout the body?
What is the Heart?
What precipitation falls when the air temperature is above freezing? (Higher then 32 degrees)
What is Rain?
Information gathered using senses or tools is called this.
What is an Observation?
A complete loop that allows electricity to flow is called this.
What is a closed circuit?
The Sun is the main source of energy that drives this Earth process.
What is The Water Cycle?
Why does the Sun appear to be the largest star in the sky?
It is the closest.
What is energy of motion?
What is Kinetic Energy?
This plant structure absorbs water and nutrients from soil.
What are Roots?
This water cycle process happens when water vapor cools and turns into liquid droplets.
What is Condensation?
A scientific investigation that changes one variable to test its effect is called this.
What is an experiment?
A material that allows electricity to pass through it easily is called this.
What is a conductor?
This organ helps you breathe by taking in oxygen.
What is The Lungs?
The Earth rotates on this invisible line
What is an Axis?
What energy is used to turn on a light bulb, and what is it transformed into?
Electrical energy into Light energy
In this food chain Sun -> Grass -> Rabbit -> Fox what type of organism is the Rabbit?
What is a Consumer?
This process moves rock or soil from one place to another by wind, water, ice, or gravity.
What is Erosion?
If a student is testing which paper towel brand holds the most water, name one thing that should stay the same to make it a fair test.
What is the size of the paper towel, the amount of water added each time, or the testing procedure
When you rub your hands together and they get warm, this force caused the heat.
What is Friction?
Dark clouds, rising humidity, and falling air pressure usually suggest this kind of weather is coming.
Rain/Stormy Weather.
The Earths movement around the Sun in one year
What is Revolution?
What is the formula for mechanical energy?
Kinetic + Potential = Mechanical
Name the two main skeleton types animals can have, and give one example of each.
What is Endoskeleton and Exoskeleton
Examples vary.
List the steps of the water cycle in order. Be sure to include the source of energy for the water cycle.
What is Sun as the source of Energy.
Evaporation -> Condensation -> Precipitation.
Scientists repeat trials mainly for this reason.
To test validity, to prove results, to improve reliability, etc.
Two balls are kicked with the same force, but one has less mass. Which ball will have the greater change in motion?
In a food chain, producers get their energy from this source.
Why do we see different phases of the Moon during the month?
Because the Moon revolves around Earth, and we see different amounts of the lit half from Earth.
When you eat food and then run, the energy changes from this form to this form.
What is Chemical to Mechanical?
A population of birds lives where flowers are deep and narrow. Some birds have longer beaks, and some have shorter beaks. Explain which birds are more likely to survive and reproduce and why.
Bonus 100 points if you name the type of adaptation that this is. Another Bonus 100 if you can tell me how long adaptations take to occur.
What are the birds with longer beaks, because that variation helps them reach food better in that environment?
Name the 6 weather tools and what they measure.
Thermometer = temperature
Barometer = air pressure
Hygrometer = humidity
Anemometer = wind speed
Wind vane = wind direction
Rain gauge = amount of precipitation
A class grows two groups of plants with Group A growing in sunlight, and Group B growing under a heat lamp. Group A heights are 8 cm, 9 cm, and 8 cm. Group B heights are 5 cm, 4 cm, and 5 cm. What conclusion could they draw based on the data, and for bonus points what could the students add as a control?
Conclusion - Plants grow faster in real sunlight/in the sun.
Control - A plant that gets no sunlight
Cart A and Cart B have the same mass. Cart B is pushed with a greater force. Which cart changes motion more? Then, if both carts are pushed with the same force but Cart B has more mass, which cart changes motion more?
What is Cart B in the first case because it has the greater force, and Cart A in the second case because less mass means a greater change in motion?
A student sees puddles disappear after a sunny afternoon and later notices clouds forming. Name the two water cycle processes that happened and what caused them.
What are evaporation and condensation?
Evaporation happened because of the Sun’s heat, and condensation happened when the water vapor cooled.
