5 Science Chemical and Physical Changes Science Survivor

Report
Science Survivor Card #1
•Ice Melting is a Chemical or Physical Change?
•You have 2 minutes to work as a team to melt 5
pieces of ice. You may use a variety of techniques
to melt your ice.
•Each team that successfully
melts their ice in
in 2 minutes will be
earn a science
immunity tool.
Science Survivor Card #2
• Chef Rabob poured salt and sugar into two
identical containers. She forgot to label the
containers. The sugar has been recalled due to
contamination at the plant where it was made. So
she cannot taste to see which container has salt
and which has sugar.
• Design a science experiment using
your knowledge of chemical
and physical changes
to determine which
container has the
sugar. Correct
Identification will earn
your team immunity.
Science Survivor Card #3
• In front of you is an egg. How can you
cause the egg to undergo a chemical
change without breaking its shell?
• Teams that correctly identify techniques to
chemically change the egg will earn
immunity.
Science Survivor Card #4
• On the table is a container with 300 mL of
water. A line has been drawn on the
container at the water line. What will
happen to the water in the container if it is
left uncovered for a week? Describe the
change which took place.
• Correct responses
will earn immunity
for the team.
Science Survivor Card #5
• On your table are vinegar, water, flour,
baking soda, a balloon, bottle, and soap.
How can you use some or all of these
materials to inflate the balloon without
using your mouth?
• Teams which inflate
their balloons in 2
minutes or less will
earn immunity.
Science Survivor Card #6
• On the table is an index card and a pair of
scissors. Can you change the index card
in a way that will allow you to walk through
it?
• You have 2 minutes to complete this task.
If successful your team will earn immunity.
• You must also
determine if this task
required you to
chemically or
physically change
the
index card.
Science Survivor Card #7
• Your teacher is holding a lighted birthday
candle. Can you identify the chemical and
physical changes that are taking place as
the candle burns?
• Correct identification will earn your team
immunity.
Science Survivor Card #8
• On the table in front of you is a mixture of
iron filings, sand, and sugar. How can you
separate these three objects? Use the
materials on your table to develop a plan
to separate these materials.
• Teams that successfully
separate or write a
detailed description
of how to separate
the mixture will earn
immunity.
Science Survivor Card #9
• On the table in front of you are an apple,
potato, and banana. Using nothing more
than a paper plate and plastic knife, how
can you cause the apple, potato, and
banana to undergo a chemical change and
a physical change?
• Successful teams
will be able to
correctly create &
identify each change
and earn immunity.
Science Survivor Card #10
• In front of you are several different rocks.
One of the rocks is limestone. We know
that limestone reacts chemically to
vinegar. Use the pipet and vinegar to
correctly identify the limestone.
• Teams that correctly identify the limestone
in 1 minute or less will
earn immunity.
Science Survivor Card #11
• The beaker in front of you contains a 50%
salt and 50% water solution. Describe,
complete with labeled illustrations, how
you would separate the salt and water. Is
a physical or chemical change required?
• Correct teams will earn
immunity.
