Sexto: Matter 2

Today you will be doing a Science Experiment! Follow the directions below to make Oobleck   newspaper measuring cups 1 cup of dry cornstarch (maicena) large bowl or pan food coloring (if you want) 1/2 cup of water     Put newspaper down on your counter or table top. Put the cornstarch into the bowl. Add a drop or two of food coloring. (Use whatever colors you like.) Add water slowly, mixing the cornstarch and water with your fingers until all the powder is wet. Keep adding water until the Ooze feels like a liquid when you're mixing it slowly. Then try tapping on the surface with your finger or a spoon. When Ooze is just right, it won't splash--it will feel solid. If you Ooze is too powdery, add a little more water. If it's too wet, add more cornstarch. Play around with your Ooze! Pick up a handful and squeeze it. Stop squeezing and it will drip through your fingers. Rest your fingers on the surface of the Ooze. Let them sink down to the bottom of the bowl. Then try to pull them out fast. What happens? Take a blob and roll it between your hands to make a ball. Then stop rolling. The Ooze will trickle away between your fingers. Put a small plastic toy on the surface. Does it stay there or does it sink? 1. Is it a solid or a liquid? 2. What is it’s mass? 3. What is it’s volume? 4. Take a photo or a video of you playing with the Oobleck?
