SCIENCE

NEW for 2017

VALENTINE CONVERSATION HEART EXPERIMENT

We dropped some candies in water, vinegar, and soda. We watched the changes over about 20 minutes. It was interesting that only some colors floated and the most chnages happened in water. We drew the results.

GOBSTOPPERS CANDY EXPERIMENT

Drop some Gobstopper candy in water and wait a short time. As the candy coating is washed off it makes a rainbow in the water.
MAGNIFYING GLASS MATCHING GAME

My kiddos love using a magnifying glass but they don't know/understand how to use it properly. They usually just press it close to their face and not away from what you want to view. This game helps them learn how to use the magnifying glass properly. They use it to view the small pictures on the card and then find the matching larger picture and place it on the board. They really enjoy this game and learn how to use a magnifying glass properly. Course they still like holding it close to their face. LOL

AIR HAS THE POWER TO MOVE THINGS

We talked about air and how it has the power to move things - best example is wind moving trees and blowing our hair.
I showed them these objects and we guessed which ones would easily move when blown with a fan.


We then conducted our own mini experiments by blowing paint with a straw observing it spread.

FOLLOW THE PATH BOTTLE

I saw this on Pinterest and tweaked it for my kids level at the beginning of school. I found a smooth sided bottle and using 3 different colored Sharpies drew 3 paths on the bottle. Each path is marked with a "s" and "f" for start and finish. I dropped a magnetic ball inside and glued the top on. The child will hold the magnet with a tripod grasp and the bottle with the non dominant hand. They will then try to make the ball follow the path of choice.

SENSORY GLOVES

Fill latex gloves with salt, sugar, rice, wheat etc. Do not overfill so there is room for manipulation. Tie off end.

SINK AND FLOAT

We experimented with what sinks and floats

CANDY CANE EXPERIMENT

We talked about how candy starts out as a liquid which is poured into a mold and when it cools off it is in the candy cane shape and now a solid. Our science question was: "Can we change the shape of a candy cane by slightly melting it?" Then I took a piece of foil and shaped it in a zig zag form and placed the candy cane on top and heated it in an oven for 250 degrees for approximately 5 min. Above is the new shaped candy cane.

DECOMPOSING

Decomposition of pumpkin pieces

APPLE SLICES WITH AND WITHOUT LEMON

Apple halves. One side treated with lemon and one without.

GROWING INDIAN CORN


Place in shallow water. This is after 1 week.


3 weeks


Right before it was time to throw out the corn I let the children use scissors and "cut the grass". They loved this!

We went for a nature walk wearing one of our dad's old socks over our shoe. We then sprayed our sock with water, sealed it in a baggie, and taped it to a window.

After 2 weeks:

 


We did the "Exploding Milk" experiment to make a rainbow.

Exploring 4 different science bottles. All 4 have the exact same items in each tube. Fill one bottle with water, baby oil, salt water, and corn syrup.

MAKE CYCLONES
Use round plastic water bottle (no curves in bottle).
Fill 2/3 full with water. Drop few drops dish soap, blue food coloring , and glitter. Replace top and secure with tape.
Child swirls bottle to make a cyclone inside.

TEACHING ABOUT GASES
Take a latex glove ( I buy a box of 50 at Smart and Final) pour baking soda into the thumb. You can make a lot of these ahead of time. Holding the thumb to prevent the child pouring liquid into it have the child pour vinegar into the fingers. Knot the top of the glove. The child shakes it to mix the baking soda and vinegar. The carbon dioxide released will blow up the glove like a balloon. The child can draw a face on the glove with markers.
Do this when teaching states of matter (gas). You could also use it if you teach about acids and bases.

PLANT SUNFLOWERS
Have children sponge paint the outside of a styrofoam cup. After it dries, fill it with potting soil and plant sunflower seeds. If you have room in your classroom, grow them at school. As a group activity, show what happens if you don't water, what happens if you don't have light. Place several plants away from the light and watch how plants reach for the light.

BUBBLES
Mix one gallon of water with one cup liquid detergent and 50 drops of glycerine.
Blow bubbles and have the children pop them.

GOOP
Mix 2 cups water with a little food coloring, add 6 cups of corn flour/cornstarch to make goop. A great outdoor summer activity.

RAMP IT!
Provide the children with an inclined plane. (Can be made with a propped up board.) Have each child pick an item from the class room and sit down, before you explain what you are going to do. Show the children a few basic items, like a car with wheels, a marble and a book. Ask the children if the item will roll down or slide down the ramp, or if it will not move. Then try it with each item. Have each child guess what the item that they picked out will do.

PAINTING WITH WATER
You just need a paint brush, and water in a bucket, oh yeah, and a nice warm summer day. Let your child "paint" with the water, and watch how the water evaporates in the warm sun. Paint rocks, trees, the sidewalk anything!!!

BALANCE PLAY
Part of science is weighing items. Provide your children with a scale or balance for them to experiment with, and plenty of various items. This can usually be tied in with your theme. If you are doing winter, let them weigh snow vs water. Which weighs more? If you are doing valentines day have them weigh heart shaped beads.

MEASURE IT
Another part of science is measuring. Provide the children with plenty of opportunities to measure things. Provide measuring cups in your sand and water table, and containers of various sizes.

SALT ART
Saturate hot water with salt.  Let the water cool, and have the child use the salt water to paint on black paper.  Then after it dries, have the child look at the crystals of salt on the paper.

PLANTS WE EAT
Show the children some common plants we eat.  Name the different parts of the plants, while you show the plants to the children.  Help the children sort the plants.  By types of fruit, and veggies.  Sort again by the part of the plant we feats, like we eat the roots of carrots and potatoes, and we eat the leaves of lettuce, and spinach.

FLOAT OR SINK
Have ser val different items on a tray, and a dish pan of water. Ask the children if they think an item will sink or float. Try it!

OCEAN BOTTLE
Clean out an empty plastic pop bottle. Add water, blue food coloring, and glitter, and maybe a few pebbles. Seal the bottle closed using a little hot glue, allow to completely dry before the children can play with it. Tip the bottle back and forth. roll the bottle on the floor.

SENSORY FISH
You need:
Blue Hair Gel
Ziplock Bag small
Plastic fish
Glitter
Place the fish, glitter and gel into the baggie. Seal the bag, and then tape it shut. Let the children feel and play with the bag at a table. Observe closely so the bag is not punctured.

MAKE A TELEPHONE
Poke a hole in the bottom of two Styrofoam cups. Place a piece of string in the bottom of one cup and tie a knot at the end of the string to prevent the string from coming completely out of the bottom of the cup. Then thread the string through the bottom of the other cup and tie another knot. The } is a cup on it's side and the ---- represents the string. It should look like this: }-----{ Have one child talk in one cup while another listens with the other cup. How long can the string be before the phone won't work?

SUN PRINTS
supply the child with a dark piece of paper. In the morning, on a very sunny day, with little or no wind, have the children find items to place on their paper. Every child should receive one rock, to keep the paper from blowing away. Have the children arrange sticks, grass, acorns and such on the paper. At the end of the day see how the sun made a picture for them.

ABSORPTION
Supply the children with pieces of material to test like pieces of cotton, plastic, wool, tin foil, etc. Supply the children with eye droppers and a cup of water. Which materials absorb water and which do not?

STAR VIEWER
Wrap a black piece of paper on the end of a paper towel tube. Seal it with tape. Poke pin hole in the paper, then look into the tube at a bright light, to see the stars.
