Fluids – Mini Labs

Cartesian Diver

Assignment: complete an exit slip that answers the question, “Why does the dropper sink when the bottle is squeezed and then rise when the bottle is released?”

Can an egg float in Water?

Assignment: complete an exit slip that answers the question, “Why does one egg sink, one hover in the middle, and one float?”

Students are to complete both exit slips, attach a rubric provided in class and submit into the Science folders.

Air Pressure VS Gravity Pull

Today we are discussing air pressure vs the pull of gravity.  We are looking at an experiment where a bottle of water has holes poked into it, predicting what will happen and then scientifically explaining the results.

The first experiment is to fill a bottle with water, put on the cap, put a hole in the side with a pin, and then pull out the pin.  What do you think will happen and why do you think that will happen?

The second experiment is to take the bottle and put 3 holes in it in a row from top to bottom.  What will happen when we pull the pins out?  What happened? Explain.

Students are completing mini labs for this with this structure:

title, problem, materials, hypothesis, result/observation, conclusion.

This is being submitted as one assignment (2 mini-labs), is an in-class assignment, and will be submitted no later than the following day.

NOTE: you should ask Mr. Ewert to show you some of the diagrams that were used in class to explain what we observed in the labs.

 

…and here is another fun video of this concept.

Mythbusters – Archimedes Death Ray – Optics – Science

Today we are watching some Mythbusters and looking specifically at how Archimedes attempted to make a death ray using soldier’s shields as reflective surfaces.  Do you think it is possible to use the reflected sun as a weapon?  Check out the worksheet from class and the episode below. Note: The video watched in class was regular speed and streamed from discovery education (which requires further passwords).  However, the video below also has the segments covered in this lesson (but you have to skip through a bit).

Today in Science – Optics

Today we introduced optics and did two experiments.  For the first we created a lab format complete with title, problem, materials, procedure, and hypothesis taking educated guesses about what would happen when we looked at the arrow through a glass of water.  See the video from class below and the similar one found online.

For the second experiment we used ray boxes to create shadow with umbra and penumbra.  We drew and labelled these.

Here is a copy of the work sheet for this from class.

Then we started watching Bill Nye the Science Guy – Optics

Here is the work sheet from class and the video itself.

VR in the Heart and Circulatory System

Today we are going into the human heart.  You are to watch the videos below in order to see the inside workings of the human heart and circulatory system.

Warning: read these instructions carefully to view the videos correctly.

To do this you will need to use either the VR headsets in class or just the youtube app on a smart device.

Note: do not watch the videos in these direct links if using a smart device or you will not get the 360 effect.  Also, when using a smart device you will need to touch the cardboard icon to make it stereoscopic in your viewer (if using vr headset).  Since you are searching on the youtube app please search fro the appropriate title indicated for each video.

If you are not using a cardboard or vr headset you can also just use the youtube app on your smart device or a netbook/laptop and use your mouse to look around inside the video.

Start with the video below to see how the inside of a blood vessel looks with the red blood cells floating within the plasma.  Search for “celluvr”

Next. watch the video below.  Search for “human circulatory system” by getschoolednow.  If you want to watch this video in vr then just hit the settings icon and select the cardboard icon

 

Once you have watched the heart video check out this vr representation that puts you fight into the right ventrical of the heart.

And finally, just for fun, here is the cartoony representation of the human heart.
