PARENTS: The FINAL Science IA of 3 rd grade will be Wednesday, May 6 th ! WOO HOO! To help your scholar prepare, have them complete this review packet. We will review this in class: no need to turn the packet back in---it’s just for fun and practice!
TIPS: Let them try to answer each question on their own---don’t just give them answers! If they are struggling, guide them towards understanding what the question is asking. An answer key has been posted to the science website, along with other great resources from the units that will be covered on the assessment. Just click on the “3 rd Grade” tab (don’t click into specific units!) to find the answer key.

SCHOLAR GOALS: Make sure you do this while completing the packet (and taking the IA!)
I read carefully and thought about what the question was asking me to do before answering.
I checked my answers to make sure they made sense with what the question was asking.

1. The diagram below shows a person using three different simple machines to make work easier.
Using the words from the word bank, label each simple machine on the line below the picture.
2. Put an X next to all the true statements.
_________ The steeper the inclined plane is, the less effort you need to exert.
3. Students wanted to test to see which toy truck would roll farther. They put Truck A on a smooth ramp, and Truck B on a rough, bumpy ramp. Circle the truck that would roll farther.

4. Scholars were discussing the results of the truck experiment from Question 3. Below are their thoughts.
Waldo: “I think Truck A rolled farther because the smooth surface had less friction.”
Paula: “I think Truck A rolled farther because the smooth surface had more friction.”
Wilone: “I think Truck B rolled farther because the rough surface had more friction.”
Elisa: “I think Truck B rolled farther because the rough surface had less friction.”
Which scholar do you agree with the most?
Describe your thinking below. Provide evidence to support your claim.
I agree with Waldo because he correctly identified that Truck A would roll farther.
I know Truck A would roll farther because the smoother the surface is, the less friction there would be to slow the object down. This tells me Truck A would roll the farthest.
5. Complete the chart below.
Wheel barrel, tongs, tweezers, scissors, clothespin, see-saw, etc.
6. Anaya has a 2-gram block, one 3-gram block, and two 5-gram blocks. On the lever below, draw how she could arrange the blocks so the lever would be balanced.

Below is a list of directions Ms. Sainvil gave to her students to complete during class.
1. In box number 2, draw a square.
2. Find the box that is underneath box 1. Draw a circle in that box.
3. Color in the circle.
4. Write your name in box 4.
Mark, Mariah, and Alyssa followed Ms. Sainvil’s directions. Below is the work that each student created.
2. Use the word bank below to order the steps involved in computational thinking.
Abstract out Write an algorithm Decompose Find patterns
Process for Computational Thinking
Step 2: ___________________________
3. “ Many computer programmers spend hours writing code.” In this sentence, “code” is referring to: a.
Computer science b.
Language computers can understand c.
Computational thinking d.

A few scholars were chatting about coding and programming and the useful of learning computer science.
Kyle: “I don’t think it’s important for computer programmers to create step-by-step directions for computers to follow because I know that computers are smart and can complete tasks on their own.”
Miranda: “I think it’s important for computer programmers to create step-by-step directions for computers to follow because, otherwise, the computer will not complete a task the way you want.”
Jazlyn: “I think it’s important for computer programmers to create step-by-step directions for computers, but I don’t think it’s necessary for every task you want a computer to complete.”
4. Which scholar do you agree with the most? Explain your thinking below.
I agree with Miranda because computers are machines. Humans have to program the computer to follow steps, and if the directions are not specific enough, the computer won’t know what to do. Computers and machines will only do exactly what the human tells them to do!
5. Use the binary code alphabet table below to decode a binary message from Ms. Priem!
Message: 101 1001 100 1111 101 0101 101 1010 100 1111 100 0011 100 1011 ! 

(inferential thinking, predictions, etc.)
Zoe did an experiment to lift an object 24 inches high using a pulley. She used loads with different masses.
Below are the results of her experiment.
1. Circle all statements that are true.
As the mass of the load increases, the amount of effort needed decreases.
As the mass of the load increases, the amount of effort needed stays the same.
As the mass of the load increases, the amount of effort needed increases.
2. The arrow in the diagram below is pointing to which part of the lever?
A the effort
B the load
C the fulcrum lever load D the lever
A an adaptation
BONUS: Label the other parts of the lever! fulcrum
3. A butterfly lays an egg. The egg hatches into a larva. The larva becomes a pupa and then changes into a butterfly. This process is called:
B a habitat
C a food chain
D a life cycle
4. Many animals blend in with their environment and can not be seen by predators. Shade in the box that best describes this adaptation. communicating hibernating migrating

evaporation
5. What process in the water cycle occurs when liquid water becomes a gas? ___________________________
Base your answers for questions 6 and 7 on the data table below and on your knowledge of science. The data table shows the air temperatures at noon for a city in New York State on five
Wednesdays during the month of March. The temperature for March 31 st has been left blank.
6. What do you predict the temperature was on March 31 st
54  F
7. Complete the bar graph below to show the data. The bar for March 3 rd is shown.

1. Which city had the greatest decrease in temperature from Friday to Sunday? Circle your response.
Minneapolis Boston
2. One each day, there was precipitation in Minneapolis. Based on the information in the chart, what type of precipitation fell on Sunday? Place a next to your response.
______Rain ______Snow
3. How do you know that type of precipitation fell? Use your science knowledge to explain your thinking.
I know the type of precipitation in Minneapolis would be rain because on Sunday the temperature is 36  F. Because the temperature is above the freezing point of water, which is 32  F, I know there was enough energy for the molecules to be in liquid form. If it were below 32  F, the molecules would have less energy and would move more slowly, and be in a solid state of matter (snow).

1. Which of the following is NOT a characteristic of all organisms (living things). a) can respond to its environment b) can take in nutrients for energy c) can run away from predators d) can grow on its own
BONUS: What is the missing characteristic of all organisms?
_____________________________________________
________ can reproduce
Base your answers to questions 2-4 on the diagram below. The diagram shows the changes in an apple tree.
2. Which type of adaptation is the plant experiencing? a) camouflage b) seasonal adaptation c) structural adaptation d) behavioral adaptation
3. Explain why the adaptation you selected for question 2 is correct.
I know this is a seasonal adaptation because the organism is responding to a change in weather, or season. If the darker months of winter never came, the tree would not have to shed its leaves to conserve energy inside its trunk. It would have enough sunlight to continue using its leaves for photosynthesis. But, because there are fewer hours of daylight, the tree dropped its leaves to save energy.

4. In the spring, flowers will blossom on the tree. What is the purpose of the flowers for plants?
Put an X next to all possible answers.
X
_________ The purpose plants growing flowers is to attract pollinators.
_________ Flowers help grow roots for new plants.

5. Water vapor changing to liquid water occurs during which process in the water cycle? a) evaporation b) collection c) condensation d) precipitation
Gas  liquid

Base your answers to question 7 and 8 on the diagram below and on your knowledge of science.
The diagram shows some organisms living together.
7. The baby birds in the nest are competing for a) food b) mates c) predators d) camouflage
