Conclusion

What did you find out? Was your prediction correct?

Yes my prediction was correct, the salt and sugar dissolved in the water just like I thought. The sprinkles, oil, oats and pepper did not dissolve just like I thought. One thing that I found interesting was the sprinkles. They did not completely dissolve. The colour of the sprinkles changed to white but they stayed solid at the bottom of the cup.
