Jerome and James_Mmm , That's Tasty

Mmm, That’s Tasty! by Neville Gardner
School Journal June 2012

WALT: Begin to use a range of scientific symbols, conventions, and vocabulary.
SC:      Complete a small science report on the taste + smell experiement

HOME ACTIVITY: Talk to whanau about flavour. What flavours do they like best? Sweet, Sour, Salty, Bitter and Umami (savoury).
What are their favourite salty, sour, bitter, sweet or savoury foods?

  1. There are 5 main flavour receptors. Sweet, Salty, Bitter, Sour and Umami.
List some foods fit each of the flavour receptors.  SHARE

  • Coffee
  • Cocoa powder
  • Sea salt
  • Lemons
  • Yogurt
  • Oranges
  • Syrup
  • Cookie
  • Muffin
  • Watermelon
  • Apple
  • Pineapple
  • Cherry
  • Pancake etc
Umami (savoury)
  • Pies
  • Mini Spinach Breakfast Quiche
  • Maple Bacon Cinnamon Rolls

  1. Record the words you didn’t know before. Add a picture or sentence to describe what they mean.

Papillae (p.26)
Its has about 10,000 taste buds that is on top of your tongue,your papillae.
Receptor (p.26 )
Receptor is a taste bud that recognizes food types like sweet,sour,salty,bitter and umami(savoury).

texture (p.25)

The feel and appearance of food or other substances.
recognise (p.28)
It is to see something and immediately identify that object / Person12

  1. On Page 29, there is the great jelly bean challenge. Mrs Parker will provide you with some Jelly Beans (or other items) to complete this task. SHARE
    Use the template for a science report below to write what you did, and what you found.
    • You need to write this very carefully (like a recipe) so that anyone who reads it can follow your experiment.
    • You will need to use objective and formal language (without personal opinion, just the facts)

Question: Do our taste buds require smell?

Hypothesis: (1 -2 sentences telling what you think/hypothesis will be the result. Answer the question) I think that we won't be able to taste anything and you will have to rely on the textures that your tongue picks up (Eg Flakes, crumble and it continues)

Materials: (List ALL the things you need to complete the experiment)
  • Food
  • Blind fold
  • Hands
  • Partner(s) (optional)
  • Nose
  • Piece of paper and a pen/pencil

Procedure: (List ALL the steps you need to take complete the experiment- like a recipe)

  1. First you prepare the food
  2. Then you put on the blind fold
  3. Then with one hand pinch your nose and make sure you can’t smell anything
  4. With the other hand put the Jelly bean or other types of food in your mouth
  5. Chew it and do not swallow
  6. Tell your partner what you taste, for example texture and taste
  7. Then when he/she has written it down on the piece of paper  
  8. After they did that take off the blindfold and unblock your nose
  9. Then tell them the difference in the tastes

Observations: (Record what happened as each step occurred)
  1. The first taste I got when I put the Jelly bean in my mouth was the sugar
  2. I also looked for the texture and what I picked up was a flakey kind of texture
  3. When I opened my eyes and unblocked my nose I immediately knew what the flavour was
  4. The flavour I guessed was Grape and the bean flavour was Grape.
Conclusion: (Answer the question. Was your hypothesis correct? Why/Why not?

Yes, My hypothesis was right because I looked for the texture and how much sugar I could taste in that bean.
