a series of steps followed to solve problems including asking questions, formulating a hypothesis, testing the hypothesis, collecting data, analyzing results and drawing conclusions
What is the scientific method?
100
An independent variable is a variable that can be tested or changed.
What is an independent variable?
100
Anything that has mass and takes up space.
What is Matter?
100
a measure of the amount of mass in a given volume.
It is what is being observed or measured. The effect caused by the independent variable also known as the data.
What is a dependent variable?
200
In volume or mass
How is space occupied by matter measured?
200
Volume is the amount of space an object takes up.
What is volume?
200
Weight is the measure of gravitational force pulling an object.
What is weight?
300
Because it helps scientists to think carefully and organize their research and observations. This method keeps scientists on track.
How is the scientific method important?
300
It is what stays the same. It is used for comparison.
What is a controlled variable?
300
Yes
Does air and space have matter?
300
1. Formula- l x w x h = volume
2. water displacement- when an object is put in to a graduated cylinder of water, the water level will rise. The amount of water pushed up equals the volume of the object.
How can volume be determined?
300
Mass is the amount of matter in an object and weight is the amount of gravitational pull on an object.
What is the difference between mass and weight?
400
1. Observation - Info gathered with 4 senses
2. Question - What do you want to learn?
3. Hypothesis - An educated guess
4. Experiment - Test your hypothesis. Collect data. Controlled experiments with only one difference
5. Analyze results - Organize data
6. Draw Conclusion - What do the results tell me. A Summary
What is the meaning for each of the steps in the scientific method?
400
It is a way to measure the mass of an irregular object.
What is Water Displacement?
400
The bowling ball would be heavier because in has more matter packed in to it.
What would be heavier a bowling ball or a balloon?
400
Density = mass divided by volume
How do you calculate density?
400
Mass is measured in grams(g) while weight is measured in Newtons(N).
What is mass and weight measured in?
500
1. Observation - plants are dying.
2. Question - would the amount of sunlight affect my plant?
3. Hypothesis - Yes, more sunlight more it will grow.
4,Experiment - for 50 days. I put one tomato plant outside in the sun and one in a dark room.
5. Analyze data - the one out side with more sunlight grew better.
6. Draw Conclusion - The plant with more sunlight will grow better than the plant with less sunlight.
If you were to grow a plant and wanted to see how much sunlight would be best for the plant. How would you use the scientific method?
500
To find the volume of an irregular shaped object such as a rock.
What can water displacement be used for?
500
Matter - people, air, trees, birds, Earth, clouds, bones, photos
Not Matter - sound and light
Which ones are matter and which ones are not?
500
If the volume is bigger than the mass the object will most likely float. If the mass is bigger than the volume that the object might sink.
How can you determine whether an object floats or sinks using volume and mass.
500
Mass is the amount of matter in an object. To find mass, place the object on a balance. Record the mass in grams.
