Hi girls so I'm currently working part time in a Science Activity Center for the summer part time and they are asking me to come up with a total of 10 activities that I can do with kids ranging from 7 to 13 in age. I will be seeing these kids for 2 1/2 hours each day and the first hour is playing and snack time, while the next 1 1/2 is doing a science activity.....
Any ideas you can help me with? Thank you for your help
Here is an example of a lesson a teacher did last year but I can't use......
Objective
Students will learn the different components of blood and their relative amounts by making their own blood.
Materials
1 spoon cornstarch
1 spoon water
4 spoons corn syrup
~30 drops red food coloring
Clear cup
Spoon
Zip-lock bags
The Science Behind It
When blood is separated using a centrifuge machine that spins things around very quickly, the different components of blood will separate into 4 layers, ranging from most to least dense:
1. Red blood cells (~45%)
2. White blood cells (<1%)
3. Plasma substances like sugar, nutrients, acids, salts, minerals, and proteins (~5%)
4. Water (~50%)
What to Do?
1. Prepare one cup of corn syrup for each student.
2. Pass out the cups to the students with a clear spoon.
3. Give each student one spoon of cornstarch and water. They should stir the substance until it is smooth.
4. Add the red food coloring to each cup until the color resembles real blood.
5. Put the “blood†in secure zip-lock bags for the students to take home.
