April 26, 2012

This is lesson plans for 2 days of preschool science. The children were ages 3 and 4. All of the links will take you to other posts within ldscraftproject and give you directions and pictures on how to do the experiment.

Preschool Ideas: Science day 1

Objective: To help the children experiment and see reactions.

Lesson Plan: April 23 & 24 Letter “S” Science

Gathering (9-9:15): Day 1: Color mixing in Ziplocs on table

Weather/Calendar/Letter/Song(9:15-9:25): Letter S-Fridge Alphabet letter “S”,

The E says “s” the S says “s” every letter makes a sound the S says “s” (also letters M-Matthew, D-Dexter, T-Tyson, H-Hope, W-Whitney, L-Lydia)

Lesson & Activity (9:25-10): Discuss what experimenting is and what happened when mixing the colors, what they thought might happen and what did.

Preschool Science Slushie Drinks

April 26, 2012

For snack time we made homemade slushies today. Super yummy and super easy. Only a few ingredients needed and a few minutes squishing a bag! Here’s what you need:

2 cups Ice
1/2 cup rock salt (found near homemade ice cream makers)
3/4 to 1 Cup Soda or juice already cold (this just makes the process quicker if it has already been in the refrigerator)
Quart ziploc
Sandwich ziploc
straws or spoons

Place the ice & rock salt in the quart ziploc bag. Pour soda or juice in the sandwich ziploc and seal the bag. Place the sandwich bag in the quart bag and seal. Start squishing! It only took the kids about 5 minutes before they were enjoying a homemade slushie!!

We drank right out of the bag with a straw or used a spoon to eat it!

Preschool Science Growing Soap

Did you know Ivory bar soap grows? All you need is a bar of Ivory Soap and a piece of wax or parchment paper. Place the soap on the wax paper and microwave for about 2 minutes. Be sure to watch the microwave to see it grow!!
I sent a bar home with everyone to try it at home. I wrote the directions on the bar of soap with a sharpie:

All lined up to watch!

Preschool Science Sharpie Tye Die

April 26, 2012

This experiment allowed the kids to see how the colors would bleed into each other and create patterns. We used:

Squares of white cotton fabric
Different colored Sharpie markers
Plastic cups
rubber bands
Eye droppers
Rubbing Alcohol

Cut square of white fabric, place over a cup and rubber band on.

Color patters, picture and designs with the sharpie marker.

Using an eye dropper, drop alcohol onto drawing and watch the colors grow and change.

Allow to dry.

Preschool Science Crystal Trees

I found the details about making crystal trees while searching for fun ideas for this week of science based activities. This was my personal favorite. I love that you have a quick interesting result that kids can see and experience. Also all of the ingredients are easily accessible. Here’s what you need:

1 TBSP salt
1 TBSP water
1 TBSP liquid bluing (Mrs Stewarts brand, they did not have it at Walmart, but did at our local Albertsons)
1/2 TBSP amonia
disposable bowl, cardboard (we used TP rolls, but you can also cut out cardboard stand up shapes)

Mix well in a sealed jar.

Place cardboard in bowl and pour solution into bowl.

Watch grow!! (this is after about 1.5 hours)

In several hours you’ll see a bit of growth and after 8+ quite a bit of growth. (This is overnight)

We tried using sharpies to draw on the TP rolls and see if we got colored crystals. We did not. You can use food coloring and it will produce some coloring on the crystals.
