Lesson 7 - Is it solid or liquid experiment??


Ph ases or States of Matter What is it??

What are the 5 phases/states of Matter? || Solid || Liquid || Gas  || Plasma  ||
 * BE Condensate
 * Properties:

Solid at level low temperature

Atoms clump together

Creates one super atom || Properties: || Properties:  || Properties:  || Properties:

<span style="font-family: 'Palatino Linotype','serif'; font-size: 11pt; margin: 0in 0in 0pt;">Like gases but not in atom form

<span style="font-family: 'Palatino Linotype','serif'; font-size: 11pt; margin: 0in 0in 0pt;">Positive and negative parts float freely

<span style="font-family: 'Palatino Linotype','serif'; font-size: 16pt; margin: 0in 0in 0pt;">Research Question: To discover what phase of matter does cornstarch and water form.

<span style="font-family: 'Palatino Linotype','serif'; font-size: 16pt; margin: 0in 0in 0pt;">Hypothesis: I think that the mystery substance and water will form a solid/liquid because…

<span style="font-family: 'Palatino Linotype','serif'; font-size: 14pt; margin: 0in 0in 0pt;">rocedure: <span style="font-family: 'Palatino Linotype','serif'; font-size: 14pt; margin: 0in 0in 0pt 0.5in; tabstops: list .5in; tabstops: list .5in; text-indent: -0.25in;">1. collect all the required materials <span style="font-family: 'Palatino Linotype','serif'; font-size: 14pt; margin: 0in 0in 0pt 0.5in; tabstops: list .5in; tabstops: list .5in; text-indent: -0.25in;">2. measure the correct amount of cornstarch (300g)using triple beam balance <span style="font-family: 'Palatino Linotype','serif'; font-size: 14pt; margin: 0in 0in 0pt 0.5in; tabstops: list .5in; tabstops: list .5in; text-indent: -0.25in;">3. measure correct amount of water (200mL) using graduated cylinder <span style="font-family: 'Palatino Linotype','serif'; font-size: 14pt; margin: 0in 0in 0pt 0.5in; tabstops: list .5in; tabstops: list .5in; text-indent: -0.25in;">4. slowly mix the water with the cornstarch, using hands to mix <span style="font-family: 'Palatino Linotype','serif'; font-size: 14pt; margin: 0in 0in 0pt 0.5in; tabstops: list .5in; tabstops: list .5in; text-indent: -0.25in;">5. after substance is created, conduct the different tests <span style="font-family: 'Palatino Linotype','serif'; font-size: 14pt; margin: 0in 0in 0pt 0.5in; tabstops: list .5in; tabstops: list .5in; text-indent: -0.25in;">6. record your observations in the table <span style="font-family: '.VnTime','sans-serif'; font-size: 18pt;">7. <span style="font-family: 'Palatino Linotype','serif'; font-size: 14pt;">make conclusion whether test means substance is solid or liquid

<span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">Quickly poke finger into substance ||  || || || <span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">Slowly poke finger into substance ||  || || || <span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">(when finger is in substance, quickly try and pull it out) ||  || || || <span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">(when finger is in substance, slowly try and pull it out) ||  || || || <span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">Squeeze a small amount of substance in your hand ||  || || || <span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">Drop a fist full of substance onto lab table ||  || || || <span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">Try and pour the substance from beaker onto lab table ||  || || || <span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">Try and pour substance from one container to another ||  || || || <span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">Hit pencil hard on substance, then drop pencil onto substance ||  || || ||
 * Test || Observation || Solid  ||  Liquid  ||

Conclusion: What happened??


 * <span style="font-family: 'Lucida Sans','sans-serif'; margin: 0in 0in 0pt;">Based on your findings from the experiments explain whether the substance is a solid or a liquid. Use your results to help in your decision: You can use diagrams to help explain your decision: ||
 * <span style="font-family: 'Palatino Linotype','serif'; font-size: 18pt; margin: 0in 0in 0pt;">Go to [] and in your own words explain what the substance actually is. Also, what could a possible future use of the substance be? ||
