Bess filled a syringe with water and left it by the sink in the sunshine. Ten minutes later she saw a puddle of water under the syring tip so she thought it was broken, but it wasnt.
What do you think caused the little puddle of water to appear under the syringe tip? It gave me a hint: it deals with the particles and kinetic energy.

The water inside the syringe absorbed heat energy from the sunshine, the water molecules were given added energy, the water expanded slightly which resulted in some of the water being forced out of the syringe, forming the puddle.

Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body water. Dissolved oxygen 0 2 4 6 8 10 12 14 16 18 number of fish observed 0 1 3 10 12 13 15 10 12 13
