FOR SCIENCE BUDDIES ONLY!!
Mission 5 - Art and Science
Science Buddies help gather necessary materials, help to read instructions, and help make sure that the junior scientist is conducting the experiments safely. You may be a scribe or a photographer to help keep a record of the experiments. I would highly recommend that you also become a part of the process by helping your young scientist with the activities.
Please experiment safely. YOU, the adult Science Buddy, are responsible for helping to gather materials and creating a safe environment and conditions for experimenting.
REMEMBER - Never leave a child unsupervised while experimenting.
This activity works because of the properties of different materials.
It is a basic chemical property for how things react with water. Some substances are hydrophobic and others are hydrophilic. Hydrophobic materials repel water, while hydrophilic materials attract or absorb water. Factors such as the texture and chemical makeup of the surface determine if a material is hydrophobic or hydrophilic. When water is dripped on a surface, you can tell by how the water interacts at the surface. Look at the drop and compare to the image below. This works best on flat surfaces instead of bumpy and uneven surfaces.
Remember that you are responsible for helping your young scientist to experiment safely. Sometimes you will need to help them to heat up solutions and use equipment in a safe manner. Please practice science safely!!
Please remember that you do not need to complete all activities, only those you would like to do. Each completed mission report gives your child the opportunity to gain additional BrainPower XP Points.
Mission 5.1: Rainbow Milk
Use a white or clear dish on white paper for this activity to show up the best.
You can make this into an experiment by trying different types of milk. Does low fat milk work the same as whole milk? Does cream work the same way? Keep track of any additional experiments as a new Mission Report.
Mission 5.2: Marbled Paper
Make sure to use some sort of art apron or old t-shirt when doing this experiment. Also, make sure to put lots of newspaper under this project. It can get quite messy!
For best results, do not allow your child to stir this up too much. A few swirls and lines through with a toothpick will give you the best results. If it gets mixed too much, you will get gray instead of a tie-dye effect.
Use a thicker paper, like cardstock, for best results.
Additional Adventures to entice your young scientist to discover more!.. Any of these can be written up as an additional Mission Report.
Go outside after a rainstorm. Look at the leaves on the plants around you. Look at the sidewalk and other surfaces. Look and keep track of the surfaces on which the water beads up versus the ones the water sinks into. This is a fun way to examine hydrophobic and hydrophilic surfaces.
Think of ways that you can make a surface hydrophobic. Is there anything that we put on the surface to change it? Think about what we usually do after we was a car… we wax it. What does the wax do to change the surface?
