In How to Make Ice Cream in a Bag follow step-by-step directions at home for making your own ice cream. Find out the science behind how this works. Smart as well as delicious! Watch a demonstration of how this works in the video below. With a few simple ingredients you can be eating a DIY slushie cold treat in no time! Even on a very hot day!

A little bit simpler science recipe you can try is making a DIY slushie from your favorite drink. The same science principles apply! Your favorite drink is pretty good with ice floating in it. When your drink has ice cubes in it, the ice cubes make the drink colder, but the ice cubes don’t make the drink itself freeze. The ice cubes IN the drink melt because they are colder then the drink itself. The drink melts the ice cubes by lowering their temperature. If you want a slushie you need to put ice AROUND your drink instead of IN it.

Melting point is the temperature at which a solid will melt. For ice this temperature is 32 degrees. If you put a drink in the freezer, where the temperature is 32 degrees or colder, the drink itself will freeze. Solid. You won’t be able to drink it!

To make your DIY slushie you want the temperature around your favorite drink to be lower than 32 degrees so the drink itself will get really cold. Keep an eye on it and stir it a lot so it doesn’t freeze solid. Make an easy slushie using ice cubes and salt. Note: the salt does NOT go IN your drink!

Salt lowers the melting point of water. Adding salt to ice cubes makes them stay frozen longer. If ice with salt added to it is packed around a liquid, like your drink, the salted ice will make your drink so cold that it will turn into a slushie!\

What You Need:

Your Favorite Drink (Soda, orange juice, lemonade, etc.)
Quart-size zip-lock bag
Gallon-size zip-lock bag
2 cups ice
1/4 cup salt
Bowl

Fill the quart size bag with your favorite drink and zip it closed. HINT: Make sure the bag is zipped really good or your slushie will taste bad when some of the salt leaks into your bag. Put the quart size bag inside the gallon bag. Add the ice and salt to the gallon bag. Next, zip the gallon size bag closed. Finally, shake the bag a lot – even play catch with it…gently. In about 15 minutes you will feel the ingredients in the quart size bag starting to firm up. What started out as a liquid is changing to a solid. When it feels done take the quart size bag out of the gallon size bag. Rinse it off good in clean water. Then open the bag, squeeze the slushie into a glass and enjoy!

When you add salt to the ice cubes you lower the melting point of the ice cubes by several degrees. The ice cubes stay colder, longer – long enough to turn your drink slushie. The secret is the catalyst – the salt. A catalyst is a substance that increases the rate of a reaction.

Science Experiment Idea

Make 3 different quart size bags each filled with the exact same amount of your favorite drink. Fill each of three gallon size bag with the exact same number of ice cubes. Add 1/8 cup of salt to the first gallon size bag and label it with a sharpie, “1/8”. Then add 1/4 cup of salt to the second gallon size bag and label it “1/4”. Finally, add 1/3 cup of salt to the third gallon size bag and label it “1/3”. Have a couple friends help you shake and smoosh the bags to make the slushies. Time how long it takes each of the bags to turn into a slushie. Which amount of salt makes a DIY slushie the fastest?

Every object on earth has potential energy. That means it COULD move even if it isn’t moving right now. When an object IS moving it has kinetic energy. In today’s demonstration you are going to store energy in a spring. That spring will have the potential to move, but it won’t move until you let it move. The marshmallow catapult you make is going to transfer energy from the spring to a marshmallow. The marshmallow will have potential energy until the catapult releases, then the marshmallow will have kinetic energy as it flies through the air.

Watch NASA astronaut Joe Acaba demonstrate kinetic and potential energy on the International Space Station by showing how an object’s potential energy changes.

Sharpie pens are permanent markers. That means that the ink will not come off with water. If something will dissolve in water it is called soluble. If something will NOT dissolve in water it is called hydrophobic. Permanent marker ink is hydrophobic. You can do a sharpie pen tie dye demonstration of solubility.

What You Need

White T-Shirt
Permanent Markers (Sharpies)
Plastic Cup
Rubber Band
Rubbing Alcohol
Dropper

Instructions

To begin your sharpie pen tie dye demonstration, stretch part of the white t-shirt over the top of the plastic cup and secure it with the rubber band – it will look like a little drum. Choose one of the colors of Sharpie pen and make dots in the center of the t-shirt circle. Choose another color and make more dots. Repeat. The circle of color should be about the size of a quarter.

Sharpie pen tie dye science experiment supplies.

Now slowly squeeze about 20 drops of rubbing alcohol into the center of the circle of dots. Drip the rubbing alcohol really slowly. What do you see happening to the ink? Let the ink dry for about 5 minutes and then you can move the cup to a different part of the shirt. When you are done making colorful circles put the shirt in the dryer for about 15 mintues to set the colors.

The permanent ink of Sharpie pens is hydrophobic. It will not dissolve in water. The permanent ink WILL dissolve in rubbing alcohol though. That is why the colors “run” to make the pretty pattern.

Science Project Idea:

Try this method of tie dying with different kinds of markers and pens. Test whether the ink in the pens is soluable or hydrophobic. HINT: the word “washable” would be a clue to help you guess the answer to that question. Then try using the rubbing alcohol. Can you find an ink that will not dissolve in water OR rubbing alcohol?

Physicists study matter – all of the “stuff” in the universe and how that “stuff” moves. One of the most famous physicists of all time was Sir Isaac Newton. Sir Isaac is most famous for explaining gravity, a concept we are so familiar with now it seems obvious to us. He is also famous for explaining how stuff moves in his Three Laws of Motion. Today we are going to look at Newton’s First Law of Motion called Inertia. This law states that a still object will stay still unless a force pushes or pulls it. A moving object will stay moving unless a force pushes or pulls it.

Gravity and friction are forces that constantly push and pull the “stuff” on earth. So, when we roll a ball, it slowly comes to a stop. On the moon, where there is less gravity and friction, “stuff” floats, and keeps floating. Try one of the experiments below to see Newton’s first law of motion in action.

Newton’s Laws of Motion: The Science Behind How Things Move

Newton’s Laws of Motion explain force and motion, or why things move the way they do. They are great concepts to explore by doing a science experiment. These are especially good science project ideas for kids who like to move! The concepts can often be explained using sports equipment or by understanding how amusement park rides work. These books offer ideas for physics experiments that demonstrate force and motion and the laws that govern them. Some of them provide the background information needed for the report that is often required to go with projects for the science fair.

The water on the earth is in constant motion. Water falls to the earth as rain and then evaporates back up into the air forming clouds. Evaporation is the process that changes liquid (like water) to gas (water vapor in the air). Water vapor in the air forms tiny droplets. When there are a bunch of these droplets clouds form. When a bunch of the droplets stick together raindrops form and fall back to earth again. After the rain falls, some of it soaks into the earth, and some of it evaporates into the air again. This cycle is call the hydrologic or water cycle. You can build construct a DIY terrarium and observe the water cycle in it.

Make a DIY Terrarium

To see how the hydrologic cycle works you can make your own miniature model of the earth in a terrarium. A terrarium is a little garden inside a clear, sealed plastic or glass container. A canning jar is a common glass container with a lid that might be easy to find at home. You can probably find the other things you need for your terrarium in your own backyard: small stones go in the bottom of the container, dirt, and a small plant or two. Look in shady areas for moss, it grows really well in a terrarium! You can also plant seeds and watch them grow.

Here are two videos that will help you. One explains how the water cycle works and the other will take you through step-by-step directions for building your own DIY terrarium.

What You Need

a Clear Plastic or Glass Container With a Lid
Stones
Soil
Plants
Water
Little Toys for Decoration (optional)

Instructions

After planting, add enough water just to moisten the soil. You don’t want to flood your garden. You don’t want standing water in the bottom of the container. When you poor water into your terrarium you are starting the water cycle. Eventually, it will “rain” in the little glass world you have made! When you set your terrarium in the sun the water inside the terrarium will heat up and turn into water vapor in the air. This is called evaporation. When the water cools back down, it turns back into a liquid. You will see condensation – water droplets – sticking to the lid of your terrarium. If the drops get large enough, they will roll down the sides of the container or fall from the lid – rain!

The close-up on the left shows the condensation that began to form on the inside of the jar after only 1 hour sitting in the sun. If there is too much water just open the lid and let some of the water evaporate into the air outside the container. If your plants look wilted or dry, try adding a little more water. It might take some trial and error to get the amount of water needed just right.

Science Experiment Idea

Make three identical terrariums. You have to use the same kind of container, the same amount of soil & the same plants. Make your variable (the thing you are going to test) the amount of water you put into the terrariums. Measure a different amount of water into each terrarium. Close the lids and watch the terrariums over several days to see which amount of water made the best environment for your plants. A terrarium with too little water will have dry plants. A terrarium with too much water will have plants with yellow leaves and maybe even mold growing on the soil!
