A group of students investigated how plants grow in different kinds of light. They placed plant 1 in sunlight and Plant 2 under a light bulb. Each plant spent the same amount of time in light.
What is the best way to keep the investigation fair?
Turn the light off.
Make sure both plants get the SAME hours of light.
Move plant 1 farther away from the window.
Give plant 2 fertilizer.
What is a QUALITATIVE observation about this plant experiment?
There are 2 plants.
The plants get 12 hours of sunlight.
Each plant has five leaves.
Both plants are healthy and have green leaves and dark soil.
What is a QUANITATIVE observation about this plant experiment?
Each plant has five leaves.
The plants have green leaves.
On the first day the plants got watered.
The plants do not have colored blooms.
What is the independent variable for the plant experiment?
The height of the table the plants are sitting on.
The type of plant.
The amount of water the plants get.
The type of light each plant gets.
What is the dependent variable for the plant experiment?
The type of light each plant gets.
The amount each plant grows.
The height of the table the plants are sitting on.
The color of the blooms.
What are the constants for the plant experiment?
The type of light each plant gets.
One plant is inside and one plant is outside.
The table height and the type of plant.
The plants are both from Lowe's.
What is the testable question for plant experiment?
Does the type of plant effect the amount a plant will grow?
Does the type of light effect the amount a plant will grow?
Will a plant grow better inside or outside?
How long does it take plants to grow?
A class wanted to see if the type of water effects if an egg will float.
In order to have the most accurate results, what should they do?
Use soda in one cup and milk in the other cup.
Use a real egg in one and a fake egg in the other
Make sure the cups are not the same.
Use the same size cup, same amount of liquid and same size eggs.
Which question is a fair testable question that can be answered by scientific experimentation and observation?
Does the amount of water effect the growth of seeds?
How many trees are on earth?
Are birds better pets than dogs?
What is your favorite type of pizza?
Sam and James each have a few different objects. They want to see which objects can sink.
How can they best compare the results of their investigations with each other?
Record in what each object does when dropped in water.
Measure the length and weight of each object.
Drop each object in different liquids.
Test the objects in groups from smallest to largest.
Jeff gave his dog three different types of dog food.
Which information should he record to find out what food his dog likes best?
the number of minutes the dog spends eating
the amount of each type of food the dog has eaten
the type of food he put in one dish
the type of dog he has
An “if, then, because…” statement that can be proven true or false through an investigation is called a ___________.
Communicating data
Hypothesis
Measuring
Conclusion
What is the best hypothesis for this experiment?
Does the type of light effect the growth of a plant?
If you change the type of light a plant gets, then the plant will grow at different rates because plants like natural light best.
Plants grow different amounts because they are different.
If you give a plant 8 hours of light, it will grow really well.
Yes, it will effect it.
Maria had 3 different sizes of soccer balls. She wanted to see which ball would fall the fastest when dropped from her roof. She wrote down the steps of her investigation.
Soccer Ball Investigation
1. Drop 1 ball from the roof.
2. Record how long it took to fall to the ground.
3. Repeat steps 1 - 2 with each ball.
What part of the scientific method is represented above?
results
procedures
hypothesis
conclusion
Alex put 2 dishes of water out in the sun. One dish had blue food coloring in the water and one was clear with no food coloring.
Which question is Alex most likely trying to answer?
Does water evaporate in the sun?
Does the color of water affect how fast it will evaporate in the sun?
Does the size of the bowl of water affect how fast it will evaporate in the sun?
How hot does it need to get to evaporate water?
Students investigate how water evaporates when placed out in the sun.
Which should the students do EVERY day of this investigation?
define the variables
form a conclusion
form a hypothesis
record the data
Students visited a zoo to see otters. They want to see if otters spend more time on land or in the water.

conclude the otters like to spend more time on land
write a report on otters
observe the otters and record how much time they are in the water and how much time they are on land
research the different types of otters that are at the zoo
