In the Yeast and Sugar video, I added different kinds of sugar to bottles with yeast and warm water. One of the bottles was a control. What should have been in that bottle?
-
Just water
No. With just water, you are removing two variables, the yeast and the sugar. You only want to remove the independent variable.
-
Water and yeast
Yes! A control should be exactly like the others, but without the independent variable (the variable you are changing in the experiment.) In this case, the variable you are changing is the kind of sugar, so the control should have everything except for the sugar. -
Water and sugar
No. The yeast is not the independent variable, so leaving it out would not be correct. -
Water and salt
No. Adding salt would be adding a new variable, which is not correct.

This is Johnson Wash, that runs down the middle of the canyon where we live. It is usually dry, but when it rains up north, we get flash floods. Is this an example of erosion, weathering, both, or neither?
-
Erosion
Yes, the is partially correct! You can tell by the muddy appearance of the water that it is carrying sand, clay and dirt along with it. Erosion is when bits of rock are moved by wind, water, ice, or gravity, so this counts as erosion.. -
Weathering
Yes, the is partially correct! The term "weathering" causes confusion because it sounds like it has something to do with weather. In Earth Science, weathering means "breaking apart." Weathering breaks rocks apart into smaller bits. The fast moving water causes smaller rocks to smash into larger rocks, breaking them apart. -
Both erosion and weathering
Yes! The flash flood in this photo is causing weathering, and erosion. As the flood decreases, and the water slows down, it will drop the sand, clay, dirt, and rocks in a process called deposition. -
Neither erosion nor weathering
No. This flash flood is causing both weathering and erosion.

The large cracks in this rock are called expansion cracks. As the overlying rock erodes away, the rock expands, causing the cracks. The cracks are an example of:
-
Erosion
No. Erosion means that the pieces of rocks are being carried away. The overlying rocks have been eroded, but the cracks are not carrying the pieces to a new location. -
Weathering
Yes! As the rocks expand unevenly, tension builds up. When there is enough stress, the rocks break. That breaking of large rocks into smaller pieces is called weathering. -
Both erosion and weathering
No. The rocks are being broken (weathering), but the pieces are staying in place, so there is not erosion. -
Neither erosion nor weathering
No. The cracks show that the rocks are breaking, which is weathering..

This is called Marble. It was once limestone, but heat and pressure changed it, recrystallizing the calcite and distorting the layers. What kind of rock is it?.
-
Igneous
No. Igneous rocks formed from magma or lava. This is not an igneous rock. -
Sedimentary
No. Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. When it was limestone it was a sedimentary rock, but not now. -
Metamorphic
Yes!. This marble been changed by heat and pressure from a different kind of rock. It is metamorphic. -
Marble is not a rock.
No. Marble is a naturally occurring solid that forms large layers in the Earth. Marble is a rock.

The nucleus of the cell contains most of the cell's DNA. Which other structure in the cell contains DNA?
-
Mitochondria
Yes! Your mitochondria have their own DNA. Unlike the DNA in the cell's nucleus, which is a mix of genes from your father and mother, all of your mitochondrial DNA comes from your mother. -
Endoplasmic Reticulum
No. The endoplasmic reticulum is involved in the folding and movement of proteins in the cell. -
Chloroplast
No. Chloroplasts contain chlorophyll, which is used in photosynthesis. -
Ribosome
No. Ribosomes are parts of the cell that assemble proteins.
