```Mission Back to the Future
Motion and Forces
EuReKa EsCaPeS!
By SuNrIsE ScIeNcE
This activity involves teamwork and attention to detail as your students imagine that they have found themselves
transported by a time machine back to the beginning of the Mesozoic Era! The Time Machine has a ‘Reverse Trip’ button,
but it requires that its passengers follow a series of clues and answer questions to ultimately find a secret message that
will grant them access back to the future! The questions on the clues involve defining, identifying the units for, and
calculating speed, velocity, and acceleration, understanding average versus instantaneous speed, analyzing basic position
vs. time and speed vs. time graphs, the basic concepts of Newton’s 3 Laws of Motion, understanding net force, the forces
of friction and gravity, and how weight of an object depends on gravity.
The students will answer questions and follow directions/riddles to locate envelopes in the classroom with more clues.
They will also be instructed along the way to input codes (in the form of letters and numbers) into the “Time Traveler”
program, which is a Google Form that they will access online. As they input the consecutive codes into the Google Form,
they will be brought closer and closer to the final clue, which will give them access back to the future.
To prepare to set up this activity, you will need to print one set of PAGES 5 – 12 for each group. These can be printed in
color or black and white. Groups of 4 are best, but if you have a lot of students in a class, up to 6 students will work! The
easiest way to differentiate the materials for the different groups will be to use a color. There is a blank circle at the
top of each envelope label and question card… just fill in this circle with a color on each item in a set. Say you have 5
groups of 4 students each… assign each group a color of a marker that you have available to you. Fill in the circle with
that color on every envelope label & question card in the set for that group. So, you will have 5 sets of envelopes and
cards, each distinguished by a specific color.
You will need 4 “large” envelopes (6” x 9” is good) and 10 “small” envelopes (4.75” x 6.75” or so) for each group. Check
your local dollar store as usually they will have packs of envelopes for cheap! Somewhere in your room, you will also need
to have a real or fake plant, a clock (analog is best but digital will also work!), a table, and a small ‘nest of dino eggs’ (put
a few plastic Easter eggs in a basket, or if you don’t have access to this, I have included a small picture of a dino egg
nest—just tape it on the wall somewhere in your classroom and you will hide envelopes somewhere nearby.)
You will follow the following directions with pictures to prepare the activity. The Google Form is already set up online and
the first question card gives them the web address for this Form. To start the game, the students are given the first
question card along with the storyline/Time Code sheet.
Along with preparing the envelopes and hiding them in specific places, you will need to print PAGES 13 AND 14 back-to-back
for each student. This is the answer sheet on which every student will keep track of his or her answers. The answer key
is provided (PAGES 15 AND 16) so you can make the correct answers a separate assessment grade for this activity!
Please follow the directions on the next pages to set up the
activity. Thank you very much for your purchase. I hope that
this activity works as a great review of these concepts for
your students in a fun and engaging format! If this product

Steps for Setting up the Escape Game:
1) Cut out all of the envelope labels and question
cards.
2) Glue or tape the large envelope labels onto the
front of the large envelopes (6” x 9”) and the small
envelope labels onto the front of the small envelopes
(4.75” x 6.75” … I used purple ones just because they
were on sale at a local store!)
3) Label each group’s set by coloring in the small
circle on all of the envelope labels and question cards
with a color. For example, I chose green for this
group.
*** Look at the clip art pictures on each envelope
label and the small pictures on the bottom right
corner of each question card. You will be matching the
picture on the question card to the picture on the
envelope label, whether large or small. Every question
card except for | will have an envelope. Two question
cards will be going directly into a large envelopes and
ten question cards will be going into small envelopes.

4) Inside the Large Envelope #| (palm tree):
 question card with matching picture (not in a
small envelope)
 small envelope with pterodactyl (question
card with the matching picture goes inside)
 small envelope with volcano (question card
with the matching picture goes inside)
These

These pictures match the
picture on the large envelope
5) Inside the Large Envelope #2 (Diplodocus dino):
 small envelope with spotted egg (question
card with the matching picture goes inside)
 small envelope with fossilized leaf (question
card with the matching picture goes inside)
 small envelope with footprints (question card
with the matching picture goes inside)
6) Inside the Large Envelope #3 (fossilized shell):
 question card with matching picture (not in a
small envelope)
 small envelope with triceratops (question
card with the matching picture goes inside)
 small envelope with ankylosaurus (question
card with the matching picture goes inside)
 small envelope with tyrannosaurus (question
card with the matching picture goes inside)
These
pictures

7) Inside the Large Envelope #4 (T-Rex bones):
 small envelope with woolly mammoth (question
card with the matching picture goes inside)
 small envelope with campfire (question card
with the matching picture goes inside)
9) You will need to hide the stuffed envelopes in certain
 The large envelope with the palm tree will be hidden
under or near a fake or real plant
 The large envelope with the Diplodocus dinosaur will be
hidden near or under a ‘Dinosaur egg nest’ (put some
plastic Easter eggs in a bowl/basket or just tape the
dino eggs picture to a wall and hide the envelopes
nearby)
 The large envelope with the fossilized shell will be
hidden near a clock (analog or digital)
 The large envelope with the T-Rex bones will be hidden
under a table (tape it to the underside of the table!)
These begin the game
8) Now you have four large envelopes stuffed with
their correct contents for the game. You should also
have a loose question card, which is given to the
students along with the storyline/Time Code to
start the game. You should also have an optional
Dino eggs picture to use as the ‘nest of dino eggs’.
*** The small label with the game’s name and
the group color is just for storing this activity.
You can bulldog-clamp the materials for each
group together with the label on top.
To Play!
Decide on a time appropriate for your students. 40 minutes will probably suffice. If you have a class period this
length, prep the students the day before with the concept/prompt and have them get right to work when they
get to class! Write this time on the blank on the storyline message. I suggest having a large visual timer as well.
Make sure that each group has a laptop/iPad/device with internet because they will need to crack the codes in the
Google Form as instructed. To begin the game, give each group the storyline message and give each student an
answer sheet (this will help keep everyone accountable in the group!). Read the prompt and explain the gist of the
game. Then, give out the first clue (the loose question card with the clock collage on it that is not in an envelope.
*** To help ease the process of re-stuffing the envelopes for your next class, ask the students to put the
question cards back into their envelopes after answering each question!
Mission Back to the Future
Motion and Forces
Keep calm and pay attention! You were fiddling around with the Time Machine at the Natural History Museum even
though the sign said, “Do Not Touch!”. A few buttons were pressed that initiated an accidental time travel! After a
strange and speedy trip back through geologic time, you’ve found yourselves peering up through a thick forest of
palms where you can see pterodactyls gliding by! The complicated motherboard of the Time Machine has a
‘Reverse Trip’ button, so you have decided to push it. The Machine begins to make some grumbling sounds and a
robotic voice says:
This ship will depart at thirty past eight.
It will leave without you if you are late.
The answers to questions will be the key
to unlock the codes presented to thee.
Yesterday is tomorrow, the future is past,
this place where you’ve traveled could be your last.
There are dangers here with large bodies and teeth,
so watch your back as you pass through the leaf.
When one minute is left you will hear a loud bell; W whether you make it, only time will tell!

This contraption of wiring on the Time Machine’s wall begins to flash with lights. You realize that it is a portable
computer with a screen, so you assume that you should bring it with you on this excursion. You have just ______
minutes to follow the voice’s instructions so you can make it out of prehistoric times alive! Be careful and good luck!
Alright, the time is ticking and you don’t know what creatures
could be out in this wilderness! This time travel mission is going to
you have to do here is define some important terms and write
sheet.
1.) The best definition for mass is…
W: the amount of space that an object takes up
G: the amount of matter in an object
P: the weight of an object
2.) The best definition for velocity is…
R: an object’s resistance to motion
C: the rate of change in position of an object
N: the speed and direction of an object
3.) The most accurate definition for acceleration is…
L: the rate of change in velocity
B: the average speed of an object over time
K: the mass of an object times its velocity
Now, use the portable computer from the Time Machine to access
the Time Traveler Program by typing the following web address
into a browser: https://goo.gl/G6QLnt. Type the letters from your
answers above into the box in order from #|-#3, in all capitals and
with no spaces.
Great work! But watch out for those pterodactyls above!
Did you know that their name means “winged finger”
because of the muscle membrane that connects their
fourth finger to their wings? They can also walk on all four
of their limbs like a vampire bat!
But their hunting style is to swoop and catch fish in their
pelican-like pouch! If a pterodactyl is flying west at a
velocity of 25 meters per second and he speeds up to 3|
meters per second in 6 seconds, what is his rate of
T: 9.3 m/s2
J: -| m/s2
F: 6 m/s2
C: | m/s2
This answer will be important for cracking the next code.
But in the meantime, do you smell smoke?? Now you may
open the envelope with the picture of the volcano on it.
You have successfully ventured into this Triassic forest!
Answer the following questions by using the word bank and
write the number associated with each answer on your
|2: speed
4: velocity
|0: acceleration
8: force
Which type of motion do the following units represent?:
1.) m/s
2.) m/s2
3.) N
4) You are not going to be strolling leisurely through this
dinosaur-laden forest! In which of the following situations
would you have the fastest speed?:
M: You walk 6 meters every 4 seconds
D: You walk 7 meters every 3 seconds
S: You walk 5 meters every 2 seconds
Time Code. Add up the numbers associated with each of
that sum into a clock image using the Time Code. Your
next clue is in the envelope with that image on it!
Yikes! The volcano is going to erupt! You need launch
yourselves out of the Triassic period before you
1.) A pterodactyl flying at constant velocity means his
acceleration is:
|5: positive
6: negative
||: zero
|7: increasing
2.) Lava flows fast for a few hours and then slow for a
few hours. Overall, its average speed is:
F: the same as the final speed of the lava
W: greater than the final speed of the lava
G: less than the final speed of the lava
V: zero
previous clue into numbers using the Time Code. Add up these
three numbers and add |000. Go back to the Time Traveler
Program and type this new number into the next code box.
Alright, time travelers! You’ve found the nest of
eggs but you better answer these questions and
get out of here quick before she returns to check
on her nest!
1.) The Diplodocus’s tail makes a booming sound
because she can whip it through the air at
supersonic speed! How much time (in seconds)
would it take the Diplodocus to whip its tail a
distance if 44 meters at the speed of 343 m/s?
You may want to use the speed triangle to help find
the formula to use for this problem. Do the work
Alright! You have reached a fossilized cycad, which
you may recognize from back in the Triassic
Period! Now that you’re in the Jurassic Period,
there are big herds of gigantic dinosaurs called
brachiosaurs. Decide which of the following graphs
represents the motion described. Write the letter

number into an image using the Time Code. Your next clue is
located in the envelope with this image on it!
the next code. Your next clue is in the envelope with the
theropod tracks (careful-theropod means ‘beast-footed’!).
Okay, time travelers, you have navigated around some large
creatures! These are the footprints of the Allosaurus, the top
predator in this North American Jurassic food chain. If you
peek over that cliff, you’ll see an Allosaurus heading for some
Diplodocus eggs that he rolled over the cliff edge.
You’ve successfully found a fossilized nautilus and time traveled
into the Cretaceous Period! But, um, you might want to know
that despite the name of the movie ‘Jurassic Park’, this is
actually the most prevalent Period of the D.I.N.O.S.A.U.R.S.! And
you have just found yourselves staring across a swamp at a
Stegosaurus! You’re going to want to be extra careful and quick
you know what’s coming towards the end of this geologic era?
Let’s just say that you’d better be safe in the Time Machine well
before the big event if you don’t want to end up extinct
yourself! Use the key below to decide which of Newton’s Laws
of Motion are being described in each scenario. Write the Law
The dinosaur found a nest with different sized eggs. He rolled all
of them over the cliff to try to crack them open on some rocks
sheet:
1.) If the Allosaurus pushed three eggs with different masses
using the same amount of force on each, which egg would
accelerate most?
M: the most massive egg
K: the least massive egg
B: all of the eggs would accelerate at the same rate
2.) Ignoring air resistance, if the Allosaurs pushed all three eggs
off the cliff at the same exact time, which one would hit the
ground first?
M: the most massive egg
K: the least massive egg
B: all of the eggs would land at the same time
Now, type the letters of your answers to the last clue and
this clue in order into the next code box in the Time Traveler
Program.
Newton’s First Law
Newton’s Second Law
Newton’s Third Law
1.) As a giant frog jumps off its lily pad, the lily pad floats
backwards.
2.) An enormous boulder has been sitting in the same place since the
Triassic Period.
3.) A mama Diplodocus teaches her baby to accelerate its tail as a
self-defense against the T-Rex. The baby can swing its tail with less
force to gain the same acceleration as its mama.
Your next clue is in the envelope with the image of the
Did you know that the name of this dinosaur, the
Triceratops, means ‘three horned face’? But, don’t worry—
it’s a herbivore and it just eats palm fronds! That frill made
of bane around its head is just for protection against its
predators. But, you’ll need to get by this guy without getting
trampled in order to know which way to go next. Write your

meaning ‘destroyer of shins’… can you guess why?!
1.) Even back in the Cretaceous Period, the laws of the
universe still applied. Which of the following best describes
gravity?:
J: it’s a property of the Earth in which a force is
applied to all objects on its surface
V: all objects in the universe attract all other
objects in the universe
R: it’s the magnetic force of the atoms of an object
attracted to the metal in the Earth’s core
1.) An Ankylosaurus walks East at a
velocity of 6 miles per hour. How far does
he walk in 45 minutes?
B: 7.5 miles
C: 4.5 miles
T: 3 miles
2.) Which two things affect the amount of gravity between two
objects?
P: mass & distance F: speed & mass D: mass & metallic nature

2.) If this Woolly Mammoth were in outer space
surrounded by nothing, what would be his weight?
V: zero kilograms C: same as on Earth
the last code, but for now, jump ahead to the time of
the Homo erectus and open the camp fire envelope!
The Homo erectus that you’ve met are quite nice! They’re amazed to see such advanced looking creatures and
they’re impressed with the T-Rex bones you’ve found. The lights on the Time Machine are blinking like crazy—
probably to warn you of the time you have until it returns without you to the Natural History Museum! The
Homo erectus are motioning for you to follow them into a dark cave. Go ahead and follow them because they
may know something that you need to know . . .
There is writing on the cave walls! Decode only the
numbers in the squares using the Time Code and type
