to scroll down and find and answer the questions. If you did not do this go back to yesterday's link and answer the evaluation questions for each lesson assigned. Check back this afternoon
for a video of the Density Column Lab.

Crossword - Forces Review

March 26 - Update
Please be sure to scroll down below the Gizmo simulations and answer the evaluation questions for each simulation.

March 26
Using you Density Column diagram from yesterday estimate the density of your objects. First look up online the density of the liquids you used and record them. Give a range of density for
each object. For example, if the uncooked pasta sunk in water but floated in dish soap its density will be greater than water but, less than dish soap.

Go to the link for Gizmos - explorelearning below and play the simulations for density. You will need to register for an account.Be sure to write down your username and password some where
you can keep for future use. The class enrollment code is J97N4L. After playing the simulations be sure to scroll down and answer the evaluation questions.

March 25
Today we are doing the Density Column Lab like the one on page 293. This is an activity we would usually do in class but I need you to try it at home working with what you have available. Use
a tall drinking glass that is as clear as possible. Liquids that you could use include dish soap, water, honey, karo or corn syrup,shampoo and vegetable oil(such as corn oil). If you want to
add something I have not listed please check with me first. After adding the liquids to your column wait a while for them to separate into layers by density. Observe to see if there is any
interaction between substances. Once the layers separate you can add small objects such as paper clip, tooth pick, uncooked pasta (spirals work well), a grape, piece of rubber band, cork,
other small objects. Be careful when adding so the objects don't get stuck on each other because than we can't tell where they would naturally float or sink. When you are finished email me a
photo of your density column. Also, make a diagram listing the order of the fluids and indicating where each object floats or sinks.

To clarify today's assignment, For each material you need to decide which fluid it will float in. Not just top, middle or bottom of the whole
column. If it is less dense it will float on a liquid, more dense it will sink. If its density is equal to a liquid it will be in the middle of
that layer of the density column.

March 17
Zoom will not begin until further notice.
Do the math page 293, calculate density and be sure to give the proper units. Email your answers to me and include where the substance would
end up in the cylinder. You don't need the picture you can just say which substance in will be in. Include whether it is at the top, middle or
bottom of that layer.

March 16
