Happy Halloween!

Students performed a chemistry experiment mixing yeast and hydrogen peroxide. The yeast acts as a catalyst and splits off one of the atoms of oxygen to create a super foaming substance which we had coming out of our small pumpkins mouths!
Have a great safe Halloween

Cylinder Density

Students continued with cylinder densities today. We will finish up with this tomorrow.
Our trout eggs arrived! we have 100 eggs in the nursery!
There is no homework.

Cylinder density

Students finished up on density of canisters and turned these sheets in today.
Students then began calculating the densities of various cylinders. We will continue with this tomorrow.

Mystery Canisters

We corrected our density sheets from Friday.
Students were then given 3 canisters and needed to make one float, suspend and sink using various objects. They then needed to determine the density of each. This will be continued tomorrow.
There is no homework.

Density

Students turned in their water station paragraphs.
Students  took a short quiz on water.
We then talked about density and students did a worksheet calculating densities and answering 3 questions.
There is no homework.

Water Stations Conclusion

Students finished their water stations. Students then took notes on water qualities.
Water is a polar molecule. Surface tension is the cohesion of water on the surface.
Cohesion is the attraction of water molecules to each other. Adhesion is water molecules attaching to other surfaces.

Homework: Students need to write a paragraph grouping the stations by the water properties and explaining what occurred using the appropriate terminology.

Water Property Stations

Students continued with water property stations. Some classes finished the rotations and some didn't. There will be  time tomorrow for students to finish up what they need to.
