During the nineteenth century, biologists found similar fossils in South America and Africa. The scientists theorized that a temporary land bridge between South America and Africa which allowed ancient species to move between both continents. In the twentieth century additional evidence showed that South America and Africa were once part of the same larger continent and that there were no land bridges between them. Which statement below best describes what biologists should do with this the new geological finding?
Biologists should update the theory due to newly found evidence.
Biologists should reject the geological findings since it conflicts with the current theory.
Biologists should update the theory because of the newly found evidence and reject
any newer information.
Biologists should reject the geological finding because they cannot change their theory
based on new information.

After reviewing and analyzing Mr. Dennis' experiment results, Ms. Giannone believes that his experiment is terrible and has dog water results. Which of the following explains what Ms. Giannone can do to confirm her analysis of the experiment?
She can replicate Mr. Dennis' experiment to see if she gets the same results.
She can change variables in Mr. Dennis' experiment to try to change the results.
She can keep the variables the same but use different tools to measure the data.
She can conduct a different experiment to show how the results should be different.
After reading a report by Mr. Dennis on how mass affects acceleration. Ms. Giannone wonders if what he found was correct. She decides to try the experiment herself. She tries to makes sure to follow the steps exactly as Mr. Dennis did, but he did a terrible job of writing them down. Which of the following best explains why the Mr. Dennis should publish all the steps of his experiment clearly?
to allow other scientists to replicate their results
to encourage the scientific community to use their methods
to show other scientists the importance of taking detailed notes
to demonstrate how many times their experiment has been replicated
Mr. Dennis is noticing that everyone in his class has been sneezing a lot lately. His theory is that, “sneezing is caused by the change in humidity, and temperature changes.” How is he using the word theory?
To describe an opinion that he has.
To describe an observation supported by data.
To describe a well-supported idea accepted by many people.
To describe a fact that has shown to be true in all circumstances.
Ms. Giannone wants to determine which candle scares away the most mosquitoes. The following data below shows the results of the investigation.
Day 1 - Rose 3 Mosquitoes and Sunflower 16 Mosquitoes
Day 2 - Rose 4 Mosquitoes and Sunflower 18 Mosquitoes
Day 3 - Rose 5 Mosquitoes and Sunflower 17 Mosquitoes
What type of investigation is this?
Ms. Giannone used an experimental investigation to directly manipulate a variable between
the flowers.
Ms. Giannone used a comparative investigation to explore the similarities and differences between the flowers
Ms. Giannone used a comparative investigation because she did not want to test a hypothesis regarding the flowers.
Ms. Giannone used an experimental investigation because she wanted to observe the flowers in their natural environment
What statement correctly uses the term “scientific theory”?
Mr. Dennis saying laying on the floor will cure the cold.
Ms. Giannone explains all cells come from pre-existing cells.
Mr. Brown says the boat should last on the water for at least 50 years.
Mrs. Hinksman explains hail will always be produced by a thunderstorm.
In class Ms. Giannone and Mr. Dennis were asked to find out how water and air affect the speed of sound. They did the following:
Ms. Giannone completed an investigation with air.
Mr. Dennis completed an investigation with water
Afterwards Ms. Giannone and Mr. Dennis compared results. They concluded sound waves travel faster in water than air.
Why did they use a comparative investigation?
They did not want to use a hypothesis in their investigation.
They observed how sound waves in nature travel differently in materials.
They had a control variable to compare to the test variable (independent variable).
They collected data on different materials to see differences in the speed of sound.
Since Mr. Dennis is a nerd, he saw fossils of giant sloths whose bones resembled smaller living sloths. He now thinks they are related. Why did he do an observational investigation?
it allowed him to create models
it allowed him to make well-supported predictions
he was able to study the natural world and come up with a research question
he was able to evaluate evidence to help him determine and control his variables
Mr. Dennis once believed that an atom was the smallest thing ever.
After several experiments, Ms. Giannone found that an atom is made up of even smaller particles. Which describes how science changes with new information?
It is accepted as true permanently.
It helps advance scientific knowledge.
It is thrown out to preserve the old information.
It hinders the advancement of scientific knowledge.
Student’s in Ms. Giannone's science class each exercised different amounts. After, they measured their resting heart rate. The data is below.
What conclusion can be made?
Exercising fewer hours a week will decrease the students' heart rate.
Heart rate remains unchanged regardless of how many hours of exercise.
Students who exercise more hours a week have a higher resting heart rate.
Increasing the amount of hours exercised will lower the students' heart rate.
Mr. Dennis - Scientific investigations should be replicable to provide additional evidence to prove the hypothesis.
Mr. Ace - Scientific investigations should be replicable to make sure that the procedures are easy to follow by others.
Ms. Chavez - Scientific investigations should be replicable so that other scientists are carrying out the same steps.
Ms. Giannone - Scientific investigations should be replicable to allow others the opportunity to confirm the experimental design.
Which student response explains why scientific investigations should be replicable?
Mr. Dennis
Mr. Ace
Ms. Chavez
Ms. Giannone
Ms. Giannone divided her class into two different groups. Each group received a toy car. The groups were asked to measure its mass on a balance and determine the time it takes to travel down a ramp. Below are their methods and results.
Which statement below best compares the methods and results obtained by the two groups?
Group 1 and 2 had similar results. This shows that they both accurately followed the procedures.
Group 2 had the most accurate results because their time was less than the time recorded in Group 1.
Group 1 did not have accurate results because their time was more than the time recorded in Group 1.
Group 2 had different results because they did not follow the procedures accurately as the teacher explained.
Mr. Dennis is playing with his toy car one Saturday when his 2 year old daughter walked in as asked “How do you think the speed of the car will change if you change the height of the start ramp?” Mr. Denis decides to conduct an experiment to answer his daughter's question, and
starts with forming a hypothesis. What hypothesis should he choose?
If the mass of the car decreases, the toy car will be less fun.
If the height of the start ramp decreases, the toy car will be more fun.
If the mass of the car increase, the speed of the toy car will increase.
If the height of the start ramp increases, the speed of the toy car will increase.
