need your help: Science lessons.....

[DreaW]

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.

Umm off the top of my head I would say;

 

1. The volcano erruption with the baking soda

2. Studying rocks

3. Recycling colored paper (you shred it and then dip it in water)

4. Testing chemicals in water with litmus paper

5. Learning about reproduction in plants by studying fruits seeds

thanks Glenda....the only thing is that I have only a week with these kids and then the following week I switch to new kids.....I also only have 1 1/2 hours to do this activity each day

Some of the things I do:

--Volcano with Mentos and Soda, works better than the baking sofda.

--Condensation, precipitation, evaporation, etc.

--Moon Cycle

--Fossils....we did this as a lab. We got raisin cookies and "dug" out the fossils (raisins).

--Force and Motion

--Simple Machines

--Living and Non-Living

 

These are just ideas, I don't have any plans with me but I can give you some off the top of my head if you like.

 

 

Do you have to follow Ca. standards for teaching?

i wish i could help but i don't teach science! my big science lesson comes during the unit on native americans when i read rainbow crow and dip part of a coffee filter w/ a dot from a vis-a-vis marker into water and the black turns into a rainbow.

The director of the science center did not mention this....The example of the lesson activity above is activity that she approved for last year

One of the more fun activities we did in chemistry class was to make ice cream using two different sized coffee cans. It was fun and it would be a great summer activity for the kids!

you can extract the dna from an onion. there should be a protocol online. it's something you can do with kids.
