(Experiment will work without food coloring). Take a strip of tissue, toilet paper or paper towel and put one end of it into the water. Observe what happens.]]> 2021-01-23 22:31:03 UTC https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1117578882 What happens to the water? gndeke1 https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1117579739 The water moves up the paper towel]]> 2021-01-23 22:32:13 UTC https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1117579739 What property of water allows this to happen? gndeke1 https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1117581291 Adhesion because stick to other substances and are attracted. Cohesion also plays a part because water molecules like sticking to each other]]> 2021-01-23 22:34:16 UTC https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1117581291 Activity 3 gndeke1 https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1117595257 Fill a small cup to the brim with water. Next, make a  guess of how many pennies/coins/small rocks you will need to make the water overflow.
Your guess____3_________  I am using _____rocks_________ (pennies, mixed coins, rocks etc.)
Next, counting, add the coins. Rocks till water overflows the cup.

Be sure to label or explain the cell type and the various organelles and their functions. gndeke1 https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1172246764 2021-02-07 00:27:13 UTC https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1172246764 gndeke1 https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1172247251 2021-02-07 00:28:02 UTC https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1172247251 gndeke1 https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1172247640 I went ahead and created a digital 3D model of an animal cell. Since it's an eukaryotic cell, it has is composed of many different organelles that help it survive and function. The nucleus is the command center and contains the DNA. The cytoplasm is important because provides a place for the other organelles to stay. The mitochondria provides power to the cell by producing ATP from cellular respiration. The cell membrane protects the cell by controlling what goes in and out of the cell. Ribosomes help create proteins from the information given by the DNA. Lysosomes contain digestive enzymes and aid in the digestion of materials. Endoplasmic reticulum helps in the transportation of proteins. Vacuoles store substances inside the cell and the golgi body helps in packaging and shipping of proteins.]]> 2021-02-07 00:28:36 UTC https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1172247640 gndeke1 https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1172248993 Link to download the 3D model ]]> 2021-02-07 00:30:52 UTC https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1172248993 gndeke1 https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1222215133 I chose the diffusion with candy experiment and I also tried out other solvents while I was at it. I put each gummy bear with their different solvents overnight and these were the results. The small gummy bears next to the large ones are the control group of the experiment. Although most of the gummy bears got larger, non compared to the plain water and sugar mixture. Baking soda mixture wasn't that bad, but plain water reigns supreme. This helped me understand osmosis a little better through actually engaging in the experiment and by also trying other different solvents.]]> 2021-02-20 23:55:47 UTC https://padlet.com/gndeke1/zux13qu96ch8cov8/wish/1222215133
