100
100
In photosynthesis, this is the input that is below the surface of a plant
Water (H2O)
100
This output is a gas.
Oxygen
100
What is this a model of?
The process of Photosynthesis
100
True or False: Mitochondria is responsible for producing energy and food in a plant cell
False!
That is the chloroplasts job!
200
What is a claim?
An argument or statement that answers the scientific question.
200
In photosynthesis, this is an input that is a gas.
Carbon Dioxide (CO2)
200
What part of a plant cell is involved in the process of photosynthesis?
Chloroplasts
200
List all 3 of the inputs of a plant for photosynthesis
-light
-carbon dioxide (CO2)
-water (H2O)
200
True or False: Plants take in Carbon dioxide and release Oxygen into our atmosphere
True!
300
What is evidence?
It backs up your claim. Evidence is any observations, data or relevant information that has been collected.
300
In photosynthesis, this is the input that is above the surface of a plant and is a source of energy
Sunlight
300
What are these pictures of?
Chloroplasts!
300
What is photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
300
True or False: Oxygen a source of energy.
False!
Sunlight is a source of energy. Especially, for photosynthesis!
400
What is reasoning?
Reasoning is the how and why the evidence supports your claim.
400
What two inputs are needed to produce glucose in a chloroplast in a plant cell?
Light and Carbon dioxide
400
What is the job of a chloroplast?
They convert light into energy and produce food for the plant cell.
400
What are the outputs of a plant in photosynthesis?
-Oxygen
-Glucose (sugar)
400
what is this a picture of?
a food chain

The information below is all parts of a CER. Identify which parts of information are the claim, evidence and reasoning.
1. According to research published in the journal of behavior addiction, overuse of the smart phone is associated with various health concerns. Such as, anxiety, depression, stress and low self-esteem.
2. Cellphones can be unhealthy for kids.
3. Kids are on their smartphone all the time and that can lead to health problems.
1. Evidence
2. Claim
3. Reasoning
500
What would happen if a plant receives no light?
They will not survive.
500
In a chloroplast, when light and carbon dioxide come together, a chemical reaction happens and produces this output.
Glucose (sugar)
500
Energy (glucose), is formed in the mango, you then take a bite into it. Where does the energy travel to?
The energy (glucose) goes through your body's digestive system and is used as a source of energy for your body.
500
How does energy flow in the plant system?
After the plant uses photosynthesis, (the process of which sunlight is used to create energy (glucose), other organisms, (like animals or bugs) that eat the plant would then have the energy (glucose). Then the organisms who eat those organisms that ate the plant, would then also have the energy.
