Before we do the lab, let’s review. In the chart, indicate solid, liquid or gas.
Property Solid, Liquid, or Gas
Takes the shape of it’s container
Has own definite shape
Can fill up an area larger than itself
Can be poured
Can be shattered with a hammer
Turns to liquid when heated
Question: Is this mysterious substance, goo yuck, a solid, liquid or a gas?
You will perform several experiments to answer this question. Follow the instructions carefully and take specific notes as you do the lab. You will need to answer this question
after analyzing all of your experimental data.
As you perform the experiments on goo yuck, complete the data table with your observations.
Experiment Observations-describe what happened Is this like a Solid, Liquid or Gas
The Quick Finger Poke Test-try to poke your finger into the goo yuck
quickly. Try to touch the bottom of the container within one second.
The Slow Finger Poke Test-try to poke your finger into the goo yuck slowly.
Try to touch the bottom of the container in 10 seconds.
Pour Test-pour goo yuck from cup to your hand. Can it be poured?
Conformity Test-transfer your goo yuck from it’s container into your hand.
Does it take the shape of your hand or does it remain the same shape as it’s original
Bounce Test-Hold goo yuck 50 cm from the table and drop it. What happens?
Shatter Test-Put a small amount of your goo yuck in between wax paper. Hit
the goo yuck once with a hammer. What happens?
Shape Test-try to form goo yuck into a ball to see if it holds it’s shape for 5
Heat Test-Make a bowl out of foil and heat goo yuck over a candle for 2
Cool Test-Let goo yuck cool to room temperature. Observe goo yuck for any
Answer the questions using the data table.
1. In what ways does goo yuck act like a solid?
2. In what ways does goo yuck act like a liquid?
3. In what ways does goo yuck act like a gas?
4. Did goo yuck undergo any physical changes in any of the experiments? Explain.
5. Did goo yuck undergo any chemical changes in any of the experiments? Explain.
6. Write a 4 paragraph persuasive essay on whether you think goo yuck is a solid, liquid or a gas. You must use your data (observations) from
your experiments to explain your reasoning. Use a pre-writing strategy to get started. Remember that you are trying to convince someone to
agree with you. Attach your essay to this sheet. Use the format below:
Paragraph I: Introduction-Introduce the problem-is goo yuck a solid, liquid or a gas. Generally discuss your lab procedure-do not give step by step
instructions. State your scientific opinion on whether goo yuck is a solid, liquid, or a gas. Give 2 reasons to support your opinion (briefly).
Paragraph 2-First statement of fact-first reason you think goo yuck is a solid, liquid, or a gas. List anecdotes to support this reason. This should be
very detailed. Prove to your reader that your reasoning is correct. Give specifics and any data you have collected.
Paragraph 3-Second statement of fact-second reason you think goo yuck is a solid, liquid, or a gas. List anecdotes to support this reason. This
should be different than your first anecdote. This should be very detailed. Prove to your reader that your reasoning is correct. Give specifics and
any data you have collected.
Paragraph 4-Conclusion-Take away statement (restate your opinion)-should summarize what you learned. You could also include further evidence
not mentioned above to further persuade your reader that your analysis is correct.
