Controlling your weight (mass) and measurements of healthy body mass.

Designing a health lunch bar

• Needs to be a balanced meal in a bar. http://kidshealth.org/parent/nutrition_center/healthy_eating/food_labels.html - How much you need in a healthy diet. 
• Decide on the ingredients and make a food label using the food label creators online.
• Analyse the recipe  - http://nutritiondata.self.com/
• Create a free account and sign in
• Go to analyze recipe.
• Select the ingredients and analyze how much would be in 100 grams. 
• If it is not a balanced meal change some of the ingredients.

The eye

Eye dissection time :)

What are the structures of the mammalian eye and how do they function?

The mammalian eye consists of many specialized cells and tissues that make up several different structures. In this investigation, you identify the structures of a cow eye and learn their functions.

Materials

• Safety goggles • Paper towels

• Preserved cow’s eye • Vinyl or latex gloves

• Forceps • Dissection tray

• Dissection probes • Dissection scissors

Parts of the eye

Conclusion and Evaluation Guide

Conclusion

Paragraph 1: Purpose, procedure and hypothesis:

1st  sentence: Summarise what you found.     In this lab the researchers found that…

2nd sentence: Summarise the procedure (what you did)

The experiment was completed using … to see what happened when…

OR The experiment was performed by… in order to ….

3rd sentence: Summarise your hypothesis and say whether your hypothesis was proved correct. (NOT Yes my hypothesis was right but the hypothesis was proven correct or incorrect)

  The researchers predicted that… because….   OR The researchers predicted that if … then…

And if your hypothesis was correct:

This confirmed (or contradicted) our hypothesis

Paragraph 2: Background information - the science behind the experiment including vocabulary about the lab. (Think about the amount of light that is being blocked)

Paragraph 3: Summarize your results

1.       The experiment showed that....... DO NOT list EVERY bit of data just the main points or the overall patterns.

 Eg -What happens to the shadow as the light source gets closer to the block?

Explain the pattern (trend seen)– use examples from your results

Were  there any results that did not fit the trend/difference in the shadow? Suggest why this may have happened?

EVALUATION

What went well in your experiment	What went wrong, what happened  - how may it have affected your results?	EBI: How would you change this?
1.	1.
2.	2.
3.	3.

What is a new research question that you would like to investigate further after you did this experiment?

Reflection

Refraction

Can you help Professor Sangkot? Explain why they might not be catching the fish - hint it's to do with refraction.

KEYWORDS:
Refraction        dense        incidence         ray           medium            angle

Here are some resources to help you.

Light
Luminous - source of light (produces it's own light)
Non-luminous - an object is un-able to produce its own light or just reflect the light.

Ray- the thinnest possible form of light which we can still see.

Beam - collection of rays 

Incidence ray

Reflected ray

angle of incidence

angle of reflection

Normal line

Medium 

refraction

ray of refraction

ray of emergence

angle of refraction

angle of emergence

dense/ density 

Sound

frequency - the number of waves (vibrations) in a second

Hertz (Hz) - measurement of frequency

pitch - high or low pitch - what you hear

loudness - volume of sound measured in decibels (dB)

amplitude - the height of the sound wave showing the loudness

Decibel (dB) - unit of loudness

Wavelength - Distance between matching points on the wave (m)

Longitudinal - Vibration at right angle to direction of travel

Transverse - Vibration parallel to direction of travel
