Sap to Syrup: States of Matter and Heat

Explore what form of energy transforms maple sap into maple syrup, then maple candy!
Video Introduction: Sap in the Sugar Maple Tree
Book: Sugaring Time by Kathryn Lasky
Resources to explain the process: Word Playhouse

- Students label the states of matter for each stage of the maple syrup process. Then, they identify heat as being the form of energy that changes maple sap into syrup, then maple candy.
- Maple Taffy Experiment with snow, students record the results of the experiment.

Lava in a Cup

First, add 3 inches of water to a cup. Next, pour 1/3 cup oil on top. Then, squirt 1 drop of food coloring. What happened?! The food coloring drop will sit on top of the oil. Grab a salt shaker and start sprinkling to get a reaction! Magically, "lava" will drizzle down and fill the cup! Watch closely and blobs will appear and shoot up to the top of the glass (salt dissolves and heads back to the surface). For the scientific explanation, check out Exploratorium Salt Volcano! For more blob activity pour a tsp of salt in (Science Bob).

Pasta Rock


Kids take whole and broken pieces of pasta (1/2 cup) and mix it with 2 tbsp of water in a cup. They dump out the water. Then, they add 2 tbsp of glue to the wet pasta (sand - optional). They stir it around, pour it on wax paper (let it dry), and create coquina! "Coquina is a sedimentary rock (limestone) that’s formed when seawater minerals cement seashells and sand together." - Education.com. Check out the full activity here!

Egg DROP!

Humpty Dumpty Project: Can you keep an egg from cracking? Kids use any materials they want to protect their egg from a giant free fall! They drop their protected eggs from a super high spot. Then, they examine their egg and see if it's still intact!

Fossil Sandwich

Investigate how fossils are formed by creating a fossil sandwich. Kids use bread to represent layers of sedimentary rock. They use books and their strength to represent heat and pressure! Then, they become mini archaeologists and extract their objects and examine the imprint left behind!

Visit Copetoons for Swedish Fish Fossil Instructions (above). This experiment demonstrates how rock keeps the shape of an animal if it hardens before the animal decomposes.

Check out Ice Age Life for creating a fossil sandwich using a variety of objects. This activity shows kids that some objects create a better print than others, just like real fossils!

Guess Who?! - Teeth

photos via cc: mouth 1 - Dana Beveridge, mouth 2 - Chris Penny, mouth 3 - Izik

This fun idea comes from Fall into First! Take photos (or have students take photos) of students' toothless mouths (showing their teeth). Next, ask kids to estimate the total number of teeth that have been lost in the class (sum of all their teeth lost). Have students go around the room and tally how many teeth each of their peers has lost. Have them count all of their tally marks and figure out the total. Whose prediction was the closet? Then, as a class, create a graph of how many teeth each child is missing. Hang the photos up, as well as the graph. Students try to guess who's mouth is whose based on their knowledge of how many teeth each of their peers has lost, as well as their keen observation skills.

Cookie Rocks and Mining

2 activities, Science and Economics:


1. Cookie Rocks - This experiment is inspired by Kinderpond's "C is for Cookie." Have all students sit around a large table. Give each kid a cookie. Then, have them destroy it! 

Weathering
First, have them experiment with a toothpick. Next, give them an ice cube to see the effects of ice on a cookie. They'll use the cube to chop at the cookie. Then, hand out an eyedropper to represent rain. Kids squirt water on the cookie. Note: You could even use a spray bottle.

Erosion
Once their finished demolishing their cookie, pass out straws. Have kids blow (wind) their cookie crumbles (rock fragments) toward the center of the table. Then, sweep their crumbs into a pile. 

Deposition
Add a couple drops of water to their crumbs (if needed) and squish them all together.


2. Cookie Mining Economics -  Check out the Museum of Science and Industry's Cookie Mining Project. Kids excavate chocolate chips from a cookie; but, first they have to purchase the materials they need and stay within their price range!

energy resources (renewable vs. non-renewable) - You can also use this activity to explore . Kids get a soft and hard chocolate chip cookie (which represent 2 landsites). Can they dig out coal without harming the landsite? Which site was easier to retrieve the coal? Visit Third Grade Thinkers for instructions!

Geometry - If you don't eat all of your marshmallows, save them for a the classic toothpick and mini marshmallow geometry lesson! Kids construct outlines of 3D solids, as well as polygons. This is a great activity to help kids count the vertices of shapes! (Note: You will want to use dried spaghetti for the rectangular prism to get the correct number of vertices) Visit Adventures of First Grade for details! There is even a scavenger hunt to go along with this activity!

Black Snake Fireworks

photo credit: all spark fireworks
Celebrate the fourth of July with snakes! All Spark Fireworks conducted an awesome chemistry experiment, black snake fireworks! Kids are amazed as a super long snake grows and twists right before their eyes! The snake is simply "puffing ash" caused by the chemical reaction of carbonate and CO2! All you need is sand, powdered sugar, baking soda, and lighter fluid. Visit All Spark Fireworks for directions and the explanation! Click here and here to see black snake fireworks in action! Check out this video tutorial by Labconco Corporation to create multiple mini snakes!

Celery With A Twist

Can you change the flavor of celery? Everyone knows the old experiment with celery, food coloring, and water to show kids how plants transport water through xylems. But, what would happen if we dissolved sugar in water? Could a celery stalk suck it up? Dissolve 2 tbsp in 1/4 cup of warm water and stir. Let the sugar dissolve completely. In another glass, just pour 1/4 cup water. In a third glass, demonstrate the classic celery / food coloring (1/4 cup water, 1/2 tsp food coloring). Finally, in another glass pour 1/4 cup of fruit punch, juice, or soda (any beverage of your choice). Optional: Spike's Science says to add sand before adding your liquid to keep your celery positioned. Then, wash your celery after the experiment to remove the sand. Now, cut  an inch off the bottom of each of your celery stalks. Leave the leafy part on top. Then, add one stalk to each of your liquids.

When the food coloring has travelled up the celery, you know the experiment is ready! If you added sand, clean your celery with water. Cut the celery up and taste it (not the colored celery, just your flavored and plain)! What happened? The celery with sugar is now sweet! You changed the flavor, amazing! Experiment with other flavors.

Note: To speed up the experiment, use a blow dryer pointed down on top of the celery's leaves. Visit Science on the Shelves for the scientific explanation.

Citrus Reaction: Natural Soda

Pour 2/3 of a glass of orange juice. Add 1 tsp of baking soda. Orange juice will bubble and fizz right before your eyes! Try this experiment out on other juices. The acid in OJ creates a citrus reaction with baking soda, releasing CO2. Apparently this mixture is good for your skin too. ;) I tasted it and it had a very unique flavor, not as good as sugary Sunkist! Visit Sunkist for more orange experiments! Visit Zoom for instructions on how to make Lemon Juice Rockets!

Ice Cream - It's In The Bag



A fun, tasty experiment that transforms a liquid into a solid right before your eyes! 

materials for 1 quart ziploc bag:
1/2 cup whole milk
1/2 cup heavy cream
1/4 cup sugar
1/4 tsp vanilla extract
1 pinch table salt

You can add chocolate chips, cherries, etc in the bag as well. Seal bag and set aside.

materials for 1 gallon ziploc bag
1/2 cup rock salt
ice cubes - enough to fill the bag half full.

Put small sealed bag inside of the larger bag and seal. Now, smush, shake, and roll the bag for 10 to 15 minutes. Check out your liquid mixture, it's ice cream! Pull it out, grab a spoon, and enjoy!

Note: The ice cream will have a soft serve consistency. If you want it to harden up a bit, toss it in the freezer.
