Dancing Raisins


You just need a clear, carbonated beverage and raisins for this experiment.  The bubbles collect on the raisins and carry them to the surface.  Then the bubbles pop and the raisins sink to the bottom.  Up and down, up and down, up and down.  Dancing raisins!

Witch's Cauldron




Materials: 2 cups, baking soda, vinegar, green food coloring, tray

Procedure:  Pour vinegar into first cup and add a few drops of green food coloring.  Mix solution.  Pour baking soda into the second cup.  Place it on a tray to catch the overflow.  Add vinegar mix to baking soda cup and be amazed!

Results:  The chemical reaction causes the release of carbon dioxide--fizzing!

Sunflowers - Part 2






Academic Practice:  Emma completed two workbook pages on numbers and uppercase/lowercase letters.  She's a fan of using a pencil.

Coloring Page:  I found a sunflower image and added a title and name line to create this coloring page.

Addition:  This game from Making Learning Fun involved choosing two brown circle numbers and placing them in the center of the sunflowers.  Then Emma used sunflower seeds to represent each addend.  Finally, she counted on to find the sum and placed the numbered blackbird on the top of the placemat.

Sunflowers - Part 1












Handprint and Footprint Sunflower:  We used yellow paint and Emma's hand for the flower petals, green paint and Emma's foot for the stem and leaf, and sunflower seeds for the sunflower seeds!  When they dried, I cut them out and Emma glued them together to create a life-size sunflower.

Ordering Numbers:  When I found these tiny baking cups in our cabinet and decided I was not likely to make mini muffins, an idea struck me.  The yellow ones looked like sunflower petals.  I wrote the numbers 1-10 on the inside and mixed them up for Emma to put in order.  This was part one of the activity.

Counting Seeds:  Next, Emma had to count out the exact number of seeds and add them to the sunflower cup.  It was a lengthy activity, but great counting practice.

Ss Do-A-Dot Pattern:  Emma wanted to do a yellow and green pattern on this worksheet.  I thought her idea and color choices were perfect!

Observing Seeds Grow:  We planted sunflower seeds a few weeks ago.  Emma loves watching the seed coats sit on top of the sprouts and fall off as the leaves unfold.

Life Cycle of a Plant:  Emma cut out the four stages at the bottom of a worksheet I found in a plant workbook, placed the pieces in order, and glued them on the flow chart.

Blow and Measure:  Emma came up with this game herself.  She started blowing seeds across the kitchen table as I was cleaning up our materials.  I suggested we use her ruler to measure the distance.

Out of This World Mobile





Emma's aunt and uncle gave her a solar system mobile kit for Easter.  It was so easy for her to assemble.  The stickers were used to connect the ribbon to the cardboard pieces.  The coolest part is that the stickers glow in the dark!  You can imagine Emma's reaction when we tested it out.  Throughout the first night, the strands fell off where they attach to the planet's rings because the tiny star stickers could not bear the weight.  A few drops of super glue fixed that issue and it has now adorns Emma's ceiling fan chain.  She just loves art, and this project was something she felt quite proud to create.

Science Experiment 9

Experiment: Shiny Pennies

Materials: Old pennies, bowl, lemon juice, towel

Procedure: Add lemon juice to the bowl. Drop in old pennies. Wait 5-10 minutes. Remove the pennies and use the towel to rub them clean.

Results: The acidic lemon juice removes the oxide from the copper pennies, making them shiny!

Science Experiment 8

The neighborhood kids liked coming over for our summer science experiments so much, that we would be asked/harassed daily. "When is the next science experiment? What will it be?" Well, I didn't have a new one ready, so I quickly found some objects for the classic sink or float experiment. They were all placed in a gift bag. The kids took turns randomly selecting a mystery item from the bag before predicting if it would sink or float. When we ran out of items, the kids asked for more. So I scrounged up a few additional trinkets for a second round.

Science Experiment 6

Scott treated the neighborhood kids to the classic volcano demonstration. After hyping it up for two weeks, he finally constructed it and invited everyone over to watch. Even the adults ventured over to see the explosion!

Science Experiment 5

Question: What will happen when you add salt to soda?

Materials:
Soda, salt, cup, spoon

Procedure: Pour a small glass of soda. Sprinkle a spoonful of salt into the cup. Observe.

Results: The soda fizzes.

Conclusion: The salt releases the carbon dioxide from the soda, causing it to rise to the top of the glass and fizz.

Science Experiment 4

You'll only need a balloon and a carbonated beverage in a bottle for this experiment. Place the balloon over the neck of the bottle. Gently shake it. Watch the carbonation fizz and create air that fills the balloon.

Science Experiment 3

For this experiment, we used a raw potato and drinking straws. First, the neighborhood kids each tried to jam a straw into the potato and discovered that the straw bent. Then Scott told them to hold their thumbs over the top of a new straw and try it again. This time the straw easily penetrated the potato. Why? When the thumb covered the end of the straw, it trapped in air, which made the straw a stronger structure. The trapped air prevented the straw from bending. Cool science!

Science Experiment 2

Sink or float? It's a great classic science experiment for little ones. Scott began by demonstrating that a wooden Lincoln Log floats on top of the water, but when a glass is placed upside down over the log, it moves to the bottom of the bowl. The air in the cup displaces the water in that area, which allows the log to appear to sink. Then I gathered some items from around the house and asked Emma to predict whether they would sink or float before dropping them into the bowl. Her favorite part was making big splashes with her tossing and playing with the items in the water.
