Observe how different substances interact with it. Tests include observation of how water and oil interact, cohesion and adhesion strength, observing capillary action, observing the effects of soap on surface tension.

Purpose: Observe and record water's many unique properties. Understand how water is important for life.  Why are these properties occurring?

Observe and measure how environmental factors such as pH can change this rate. Measure the pH level and the speed at which oxygen is produced,then find the rate of oxygen production. Observe how the rate changes with the pH level. Making the pH significantly higher or lower sped up the rate of production, though we’re not sure why this happened.

Purpose: Observe how conditions can affect enzymes. Learn how ideal enzyme conditions work in the body, and why enzymes are denatured.

Do the same while using inhibiting factors such as temperature and shape. Observe how inhibitors affect the number broken. Break toothpicks while visibly observing the effects of outside forces on the “enzyme” used in the lab. Try to find different ways of slowing down or speeding up the enzyme, while the enzyme tries to do its job as efficiently as possible.

Purpose: Similar to how enzymes can become denatured due to environmental conditions.

The  higher molarity solutions drew out more water from the tube. This lowered its mass due to water loss. Lower molarity solutions raised the mass due to water flowing into the tube. The mass stayed the same when the water potential in the tube and solution were equal.

Purpose: The purpose of this lab was to oserve the effects of water potential and osmosis in real time at a visible scale.]]> 2018-11-05 18:55:39 UTC https://padlet.com/jill_schroedl/eievwqemm9mu/wish/300663690 Cell Temperature Lab jill_schroedl https://padlet.com/jill_schroedl/eievwqemm9mu/wish/300669308 Description: Observe how temperature affects the structure of cells and cell walls. Cell walls will break down faster in hot water. This was measured by comparing the color of beet roots soaked in water of varying temperatures. Near boiling water was much more effective than near freezing water. This is because the cell wall is weakened and bursts when the temperature is great enough.

Purpose: Observe how temperature affects cell structure.]]> 2018-11-05 19:03:24 UTC https://padlet.com/jill_schroedl/eievwqemm9mu/wish/300669308 Carrot Osmosis Lab jill_schroedl https://padlet.com/jill_schroedl/eievwqemm9mu/wish/300675440 Description: Place carrots in varied solutions of sugar and salt. Observe how the mass of the carrots change due to water gain or loss from osmosis. Measure the difference is mass of each carrot. The masses did not change as much as expected.

Purpose: Observe the effects of osmosis through carrots.]]> 2018-11-05 19:12:10 UTC https://padlet.com/jill_schroedl/eievwqemm9mu/wish/300675440 DNA fingerprint lab jill_schroedl https://padlet.com/jill_schroedl/eievwqemm9mu/wish/325088578 Description:
