This process uses sunlight, water, and carbon dioxide to make sugars in plants
Photosynthesis
What process turns liquid water into water vapor in the water cycle?
Evaporation
What state of matter is water when it is water vapor?
Gas
Define the term "producer" in one sentence
A producer is something that makes its own food from the sun
Name one human activity that can reduce negative impacts on local natural resources
Example: reduce water use, recycle, plant native species, use less single-use plastic, conserve energy.
Name the role of an organism that makes its own food and is usually at the base of a food chain
Producer
List three places where Earth’s fresh water is stored
Glaciers, Lakes, Atmosphere
True or false: when water becomes vapor, it become a different substance.
False
What does "decomposer" mean? Give an example.
Fungi, Worms, Bacteria
What steps would you include to test which of two composter designs would help materials break down faster?
keep identical compost materials and amounts, measure temperature, mass loss, and time to breakdown, compare decomposition rate
Draw or describe a simple model showing how matter moves from plants to animals to decomposers
Producers --> Comsumers --> Decomposers
Explain why the Sun appears larger and brighter than other stars
It is closer
Explain how conservation of mass is observed when you combine two substances of 70g and 80g and they make a substance that is 150g.
When you combine two things to make a third thing, matter is neither created nor destroyed so the mass must be an addition problem.
Define "condensation" and use it in a sentence about the water cycle
Condensation is when water vapor turns back into liquid water droplets. When condensation occurs, clouds form.
Explain how a dog CANNOT have black fur if its parents have blonde fur.
The dog gets its genes from its parents and it can only have the trait that it inherits from its parents.
Give two pieces of evidence that decomposers recycle materials back to the soil and air
Plants use nutrients, composters break down waste, etc
Use a model or short description to explain why we have day and night on Earth
(see model)
Describe how gravity acts on objects near Earth and state the direction of the gravitational force
Gravity pulls objects toard the center of the Earth.
What is a "chemical reaction"? Give a classroom example that shows new substances form
Two things are combined and a new thing is produced. Baking soda and vinegar, for example.
Give an example of an engineering improvement (innovation) to a common classroom tool and explain how it meets a need or solves a problem
add a rubber grip to a pencil to make it easier for small hands to hold — reduces slipping and improves comfort; or redesign a clipboard to include a built-in storage compartment.
Explain how energy from the Sun becomes energy that an animal uses for motion. Include the roles of producers and consumers.
The energy from the sun is made into food by plants through photosynthesis (producers), then those are eaten by consumers who use it for energy
Design one change to a simple water filter that would help remove tiny particles (particulates)
(see explanation)
(see model)
Define "model" in science and explain why scientists use models when studying Earth, organisms, or systems.
A model is a drawing or diagram that shows how things work in science.
How can we represent W, E, and D using chalk outside? Describe how each one is shown.
