# 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).

# Parts of the Human Eye

This week you will learn how light enters the human eye and is translated into vision.  Today we are studying the parts of the human eye.  Follow this link to quizlet to study the vocabulary and parts of the human eye. You can also watch the video below, which we watched in class.

We watched this first video to draw and label our own diagrams of the human eye

Then we watched this video to learn more about how the parts of the eye work and to complete our labelling

Then we watched this rather entertaining video that gets more in-depth about how the eye works.  It gets more in-depth than we are expecting students to know, but this fulsome information helps us understand how the eye really works, and shares really cool facts to support our learning.

Then, label the following diagram to show what you have learned. 19.02.05 human eye worksheet

# Optics – Discrepant Events

Today we are doing some mini-labs based on the following video.  For each of these you are to create a mini-lab consisting of…

Title

Problem/Question:

Procedure: see video on class blog

Hypothesis:

Obserations:

Conclusion:

Here are the two problems you will need to write:

Penny in glass problem: what will I see when I put a glass on the penny and water in the glass?

Colour Wheel problem: What will happen if I spin the colour wheel really fast?

We will watch these together in class.  If you are at home, then you are to complete your problem/hypothesis, and hypothesis prior to watching the video.

For the next video watch only until 1:25, then do up to your hypothesis…then watch the rest of the video to complete the experiment.

For this last video, first predict what will happen when he puts th am radio in the cage.  Be sure to back up your prediction with past knowledge and experience.

# 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.

Note: The notes below talk about using these videos in VR.  You can also watch them just as they are and then use your mouse to “look around”

### 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.

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.

# Cells – An Introduction

Today we are going to introduce ourselves to cells.  To get started we will watch some videos (some in virtual reality), do some online vocabulary exercises, read some material from our Science text book, and also practice labeling some animal and plant cells.

Watch this video here for an introduction on the parts of a cell
