Math Football

minjih2015

Our goal was to make a football with spaghetti and marshmallows. We first thought that using the whole spaghetti will make the football unstable, so we decided to break the spaghetti in half. After that, we attached the spaghetti with the marshmallows and made hexagons to create a 3D figure. Unfortunately, the figure was not stable and became bigger than we thought. We broke the spaghetti in half again and made hexagons and triangles to create the football. We thought that if we use two different shapes, it will make the figure stronger. While we were making the football again, we realized that the figure was much stable this way. We only had 20 minutes to do this project so we weren’t able to finish it but here is a picture of the football we made.20160907_144045

By doing this project, I realized that football relates to geometry.  We saw a video titled ‘Geometry of Footballs and the Cube-shaped Ball’ and I learned that most of the football that we know is made out of 12 pentagons and 20 hexagons.

Taming of the Shrew Stop Motion Induction Scene Project

This play is named “The Taming of the Shrew” written by William Shakespeare. My partner is Sarah. She was responsible for taking the stop motion pictures while I was moving the Lego figures. In the end both Sarah and I worked on the audio and narration of the video. Inset is the main play, and the induction is the introduction of the main play. As the induction scene finished, the players that were on stage moved to the side. They prepared to watch the main play. The induction scenes of our play applied to “ The Taming of the Shrew.” “Sly” a character of the play begins to be mocked. Thus helping cool the audience down with a sense of comedy and entertainment. The inset began when the bed that “Sly” and “Page” were sitting on slid towards the side preparing themselves to watch the main play. The app used to help produce this video was “Stop Motion.” We would move the Lego figures with slight movements that would create a flow of action and scenes. After the filming of the video; we started to record the narration and voices. In order to record the audio, we downloaded an app called “Text to Speech” for different accents. For extra effects we included sound effects that helped present the play more engagingly. For example, when the players had knocked the door of the lord’s home; we included the sound of a knock on a wooden door. One of the challenges that we had experienced was working on the audio. We were not always able to fit the amount of narration and voices that we had originally prepared. Another challenge we were faced with was the process of moving the Lego figures. The Legos themselves were quite small and dainty thus making it quite difficult to keep them in place. By doing this project, it gave us more of an understanding and visual of the play.

Modeling Mitosis

minjih2015

In this lab our group used pipe cleaners and string to model mitosis

 

Interphase

20160510_142917

The small circle represents the nucleus and the bigger circle represents the cell membrane.

20160510_142944

There are chromatins inside the nucleus.

20160510_143038

During the interphase, all of the DNA is copied. We added the other half of the pipe clearners.

 

Mitosis

<Prophase>

20160510_143245

Replicated DNA molecules join together to form sister chromatids. Two same colour and size pipe cleaners are tied together.

20160510_143334

We added small strings to the cell, 4 at each end, to represent the spindle fibres.

20160510_143610

We attached the strings from either end of the cell to one of the sister chromosomes.

20160510_143632

The nucleus is removed.

<Metaphase>

20160510_143703

The chromosomes line up in the middle of the cell.

<Anaphase>

20160510_143808

We untied the sister chromatids and moved the 2 halves of each chromosome away from each other to opposite sides of the cell.

<Telophase>

2016-05-14 14.20.27

The spindle fibres disappears and 2 nuclear membranes form.

 

Cytokinesis

20160510_143938

Cell divides into two.

Currents from the Kitchen

1. Prediction: Potato will produce the most electric voltage because the juice from the potato will help to make a electric charge

2. Materials : Potato, Lemon, Orange, Voltmeter, 2 steel nails, 2 copper wires, 4 aligator clips, Miniature bulb

3. Procedure :

a) Insert 1 steel nail and 1 copper wire to the potato

b) Use 2 aligator clips to connect steel nail and copper wire to the voltmeter

c) Exchange the voltmeter to miniature bulb. See if the bulb lights up.

d) Record the results

e) Try lemon and orange with the same procedure

4. Results : 

20160407_142039

Potato : 1.5 voltes, didn’t turn bulb on

20160407_142422

Lemon : 2 voltes, didn’t turn bulb on

20160407_142932

Orange : 1.5 voltes, didn’t turn bulb on

5. Advanced Experiment :

Use both fruits, orange and lemon at the same time. Use 2 steel nails and copper wires. Connect the two fruits and the voltmeter with 4 aligator clips. Try the minature bulb to see if it lights up.

6. Result of Advanced Experiment :

20160407_143154

Orange and Lemon : 3 voltes, didn’t turn bulb on

7. Observations : 

  • It was 0 voltes when our group inserted 2 steel nails in one fruit
  • We should have checked if the light bulb actually turns on by a battery
  • It would have been better if we had more time to try other fruits or vegetables

8. Questions : 

If your bulb doesn’t glow, how can you find out if electrons are flowing?  I can use a voltmeter to find out if electrons are flowing.

If your bulb doesn’t glow, why not?  It might not have the power to light up the bulb.

What is causing electrons to flow in this experiment? The aligator clips allows electrons to flow.

How can I use this in my everyday life?  I can use this when power goes out.

9. Conclusion : My prediction was incorrect. Lemon produced the most electric voltage.
