Materials

ObservationsCorn syrup (Steve)

Before After

Weight 67g 44g

Water egg (Bob)

Before After

Weight 77.4g

91.4g

3 Visual Observations There’s bubble rising in the egg when it is on

the vinegar. There’s more bubble rising and the egg is

trying to float . Egg’s are still floating and at the top there’s a

foam . It’s no longer have a shell and its squishy . After sitting on corn syrup for 24 hours the

egg looks shrivelled up. After sitting on water for 24 hours the egg

looks large and it’s not floating.

Water egg (Steve) Weight - I think it is

going to be lighter. Size – I think it is

going to be smaller. Look – I think it is

going to look the same.

Hypothesis(Water)

Corn Syrup (Bob) Weight – I think its

going to be heavy. Size – I think its

going to be bigger. Looks – I think its

going to look the same.

Hypothesis(Corn Syrup)

Conclusion(Water egg)

Corn syrup egg become smaller.

The water moved out to the egg.

Corn syrup egg become lighter .

Corn syrup egg looks the same .

Corn syrup egg

Conclusion

Water Egg WRONG The size of the egg

become larger The weight of the

egg got larger RIGHT The look of the egg

didn’t change

Corn Syrup Egg WRONG The size of the egg

become smaller The weight of the

egg become lighter RIGHT The look of the egg

didn’t change
