Variables
What are the 3 variables that are found in a scientific experiment?
Independent, Dependent and Constant
Plants produce these 2 things during photosynthesis.
What are oxygen and glucose (sugar)?
Define the Law of Conservation of Mass.
Mass cannot be created or destroyed.
The initial mass must equal the final mass.
The star closest to our planet.
What is the Sun?
What are the steps of the scientific method?
Ask a question, form a hypothesis, plan your experiment, experiment, collect and record data, analyze and draw conclusions, come to a conclusion, communicate results, think of a new question.
Define all three variable in an experiment
IV- Changed
DV- Measured
C - Stays the same
How did we conserve the mass in our FPT project?
We added a lid (balloon)
The path one object takes around another object in space.
What is an orbit?
define the problem, research, brainstorm ideas, develop solutions, make a prototype, test a prototype, share with community, redesign (if needed)
What is the independent variable?
1. Gather the three beakers of equal volume
2. Fill each beaker with the same amount of water
3. pour the same amount of salt into each beaker
4. Put one beaker in the refigerator
5. Put one beaker under a heat lamp
6. Put one beaker on the counter.
The temperature where the plants are placed.
mass is the amount of matter in an object.
One of these takes about 365 days.
What is Earth's revolution around the Sun?
What is the different between Scientific method and Engineering design?
Engineering design solves a problem. Scientific method answers a question.
What is the constant?
1. Gather the three beakers of equal volume
2. Fill each beaker with the same amount of water
3. pour the same amount of salt into each beaker
4. Put one beaker in the refigerator
5. Put one beaker under a heat lamp
6. Put one beaker on the counter.
beakers and amount of water
I poured 40 mL of water into a 100mL container. Then moved the 40mL of water into a 50mL container. Did the volume of water change?
No, the volume of the water didn't change. Only the size of the container changed.
This takes about 27 days.
What is the moon's revolution around the Earth?
What makes a question testable?
If it can be tested and measured during the experiment
What would happen if you didn't have constants in the experiment?
The results wouldn't be accurate and could be inconclusive.
Imagine that you could put popcorn kernels into an airtight popcorn popper so that no particles could leave of enter the popper. You then measure the mass of the pepper with the kernels. After the popcorn has popped, the mass of the popcorn will be...
The mass of the popcorn will stay the same because the container is air tight (closed)
the Earth does this in a 24 hour period.
What is rotate on it's axis?
What is an example of something you could complete an experiment for?
