Esther became interested in insulation while her parent’s new house was being built. She decided to determine which insulation transferred the least heat. She filled each of 5 jars half-full with water.
She sealed each jar with a plastic lid.Then she wrapped each jar with a different kind of insulation. She put the jars outside in the direct sunlight. Later, she measured the temperature of the water in each jar. What is the independent variable?
The type of insulation
The temperature of the water
Number of houses
The amount of sunlight
only 1
The type of variable that responds to the experiment and is what you measure or count to determine if your hypothesis is true.

What makes a good scientific question?
The question can be answered by yes or no.
The question can be answered by doing an experiment.
The question can be answered through extended thought.
Larry wants to test different types of fertilizer on tomato plants. He wants to see if one works better than the rest. He has 4 plants. The first one gets no fertilizer, the second one gets fertilizer A, the third Fertilizer B, and the fourth Fertilizer C. They each get the same amount of sunlight, same amount of soil, same type of soil, same amount of water, and are grown in the same air temperature in the same greenhouse. Larry is counting the total weight of tomatoes produced by each plant to determine how well the fertilizers worked. what is the independent variable/
type of fertilizer
same type of soil
weight of tomatoes grown
same amount of soil
Blanche wants to try out different types of cleaners to clean the school floors. She experiments using cleaner A, cleaner B, cleaner C, and then just water. She puts cleaner a on 4 tiles, cleaner b on 4 tiles, cleaner c on 4 tiles, and then she cleans the last 4 tiles with just water. She uses the same amount of cleaner, the same type of times, the same amount of grime on the times, same air temperature, and leaves it on for the same amount of time. at the end, she identifies which one has the least amount of remaining grime to identify which cleaner worked best. What would be a good title?
Cleaners
Clean tiles
The effect of different cleaners on floor tiles
If you use floor cleaner on floor tiles, it will remove grima because of the properties of the cleaners.

Erin is testing to see how different amounts of nitrogen infused in the soil will impact the height of her corn plants. She puts two corn plants into two pots. One is filled with nitrogen infused soil and the other is not. She puts the regular soil pot outside and the nitrogen infused plant in her bathroom. The corn in the regular soil grows to 7 feet tall and the corn in the nitrogen soil grows to 2 feet tall.
What is the dependent variable?
The regular soil
The nitrogen infused soil
The height of the plants
The plant in the bathroom

Details from an image can be textual evidence.
Which sentence is the claim?
In our experiment, the blocks had different masses, 20 g., 30 g., 44 g., 123 g and 142 g but the time for all five blocks to fall was about the same. It took between 1.5 and 1.8 seconds for them to fall. No, mass does not affect how quickly an object falls. Since the blocks had different masses but took about the same time, I know that mass does not affect how quickly something falls.

Vince's experiments off camera found that the Shamwow is very absorptive, is washable, and has many uses. He demonstrated on camera how absorptive the shamwow is by soaking up a container of water and cola from carpet. He also gives Shamwow a 10 year warranty. All of these facts demonstrate that Vince's claim is true - you should buy Shamwow!
