MOULD EXPERIMENT

SLIDE 2

PURPOSE/GOAL

 To determine which of these controlled

vegetables, tomato, carrot, spinach, potato and cabbage, grows the most mould in the same location.

SLIDE 3

VARIABLES

 The five different types of vegetables are

tomato, potato, carrot, cabbage and spinach. All are in the same location and are controlled.

SLIDE 4

CONTROLLING THE EXPERIMENT

 I have controlled my experiment by using the

same containers and placing them in the same location.

SLIDE 5

HYPOTHESIS

 If the tomato holds the most mould of all the

vegetables then it will grow most mould because mould needs moisture to grow.

SLIDE 6

MATERIALS/EQUIPMENT

 Camera  5 containers  5 bags  Half a tomato  Half a potato  Piece of cabbage  Piece of carrot  Spinach  A knife

SLIDE 7

PROCEDURE

 Get vegetables.  Slice potato in half.  Slice tomato in half.  Rip piece of cabbage.  Slice part of carrot  Lay vegetables in containers barely touching it.  Fill containers in ziplock bag.  Leave it and observe it growing mould.

SLIDE 8

DAY 1 0% MOULD ON CARROT.

0% MOULD ON THE SPINACH

SLIDE 9

0% MOULD ON POTATO.

0% MOULD ON TOMATO.

SLIDE 10

0% mould growth on cabbage.

SLIDE 11

DAY 4 MOIST IN BAG. 0% MOULD GROWTH.

QUITE BLURRY. SPINACH DEHYDRATED A BIT.

SLIDE 12

MOIST IN BAG. THE MOIST EVAPORATES BUT IT CAN’T GET OUT SO THE MOIST STAYS THERE. 10% MOULD GROWTH ON POTATO. MOIST IN BAG. THE MOIST EVAPORATES BUT IT CAN’T GET OUT SO THE MOIST STAYS THERE. 5% MOULD GROWTH ON TOMATO.

SLIDE 13

6% of mould growing on the sides.

SLIDE 14

DAY 8

MOIST INSIDE BECAUSE OF TEMPERATURE DIFFERENCE AND THE MOIST EVAPORATES BUT IT CAN’T GET OUT SO THE MOIST STAYS

THERE. 0% MOULD GROWING ON CARROT.

MOIST INSIDE. SPINACH DEHYDRATED.

SLIDE 15

30% MOULD GROWING ON POTATO.

MOIST BECAUSE OF TEMPERATURE DIFFERENCE.. VERY HARD TO SEE. LETTING OUT JUICE AND 50% MOULD GROWING.

SLIDE 16

Moist inside because of temperature difference. 10% of mould growing.

SLIDE 17

DAY 12

MOIST BECAUSE OF TEMPERATURE

DIFFERENCE. 1% OF MOULD GROWING ON

CARROT. SPINACH DEHYDRATED.

SLIDE 18

MOIST INSIDE BECAUSE OF TEMPERATURE

DIFFERENCE. 40% OF MOULD GROWING.

VERY MOIST. HARD TO SEE. 60% MOULD GROWING ON TOMATO.

SLIDE 19

A bit moist inside because of temperature difference. 15% mould growing.

SLIDE 20

CONCLUSION

 In conclusion, the tomato grew the most mould

and the carrot grew the least mould. My hypothesis was correct. The tomato should’ve grown mould fast because it held the most

moisture. The cabbage and carrot should’ve

grown the least mould because they were the driest vegetable.

SLIDE 21

NEW UNDERSTANDINGS AND QUESTIONS

 I found out that mould needs warmth, moist,

light, oxygen and food sources to grow mould. Dry and cold areas are not good places to grow

mould. Tomatoes and potatoes are good food
