Making things is always fun, but we do not always have the opportunity to make stuff while we are in class. This activity allows you to make something at home, which is very fun to make AND play with! Background Info:
Did you know you can actually make stuff like playdough, silly putty, and slime at home? That’s right! You can make it instead of buying it! You may even think it is more fun to make it at home because you are able to mix everything together and even make a mess! There are several different ways you can make all these but this activity will have you making SLIME! I hope you are ready for some fun in the kitchen while learning how to measure at the same time! Background Info:
Before you start please check to be sure you have everything so you are ready to go! Ingredients: Elmer’s White glue bottle Borax Water (from the faucet) Package of food coloring Before You Begin:
2 bowls, large (these will be from your house, I did not include them)
What To Do: Begin first, by deciding what color you would like your slime to be. You can choose one of the basic colors from the package: Red, Yellow, Blue, or Green, or be a little more adventurous and mix colors to create your own. Here is a chart that may help if you choose to mix colors to make your own. Taken from: http://www.cookidscook.com/food-color-blend-chart.html
What color do you plan to make your slime? _____________________________________________________________________________________________________________________ Explain why you are going to choose to make your slime that color. Is there a special reason? Is it your favorite color? Did it seem like a fun color to make? ___________________________________________________________________________________________________________________________________________________________________________________________________ Write:
Now that you have decided what color to make your slime you must get ready to actually make it. Wash your hands with soap and warm water. Clear a spot on the table or counter so there is plenty of room to work in. Bring all the ingredients and materials to the cleaned, cleared off spot. What To Do:
What To Do: Start by getting one of the large bowls. Then find the measuring cup labeled ½ (½ cup). -It is plastic, small, and you cannot see through it. You will also need to find the liquid measuring cup. -This kind of measuring cup is much like a cup, has measurements written along the outside, and can be seen through.
What To Do: Take the ½ cup and fill the entire thing up with Elmer’s White Glue. Empty the glue into the bowl. Set aside the measuring cup to be washed. You will not need it any more. Take the liquid measuring cup, go to the sink, and fill it with water until it hits the ½ cup mark. -If you have problems finding the ½ cup mark try looking around the middle of the cup.
What To Do: Rest the measuring cup on the counter, step back and look to see where the water level is. -You will see almost what looks like a bubble at the top of the water. To measure correctly, the top of the “bubble” should be right at the ½ cup mark. -If you have too much water, pour some out. If you do not have enough, pour some in. This may be difficult, but by practicing, it will become easier! Once you have the correct amount of water in the liquid measuring cup, pour the water into the bowl along with the glue.
Now you may put in the drops of food coloring to the glue and water mixture. Once you have finished putting in the food coloring you may begin to mix it all together. If you prefer, you can use a spoon, otherwise just use your hands! Make sure to mix it all together very well. It make take a minute or two. Have someonein your house take a picture with the disposable camera of you mixing everything together. When the colored glue and water mixture is completely mixed, set the bowl aside. Wash your hand with soap and warm water. Try to get any food coloring or stuck on glue off. What To Do:
Reflect and Write: How did the measuring and mixing the first bowl go? What did you think was the hardest part? ___________________________________________________________________________________________________________________________ How did the coloring of the mixture go? Did the color turn out the way you wanted it to? If not, what could you have done differently? _________________________________________________________________________________________________________________________ _______________________________________ __________________________________________________________________________________
Now, start by grabbing the other bowl. Find the little spoon-shaped measuring tool called the teaspoon. Fill the teaspoon up with Borax. -Because the teaspoon is very small, you will not need very much Borax so pour slowly. - It is a good idea to pour the Borax over the sink or trash can in case you spill any. Once the teaspoon is filled with Borax, empty it into the new, empty bowl. What To Do:
Find the liquid measuring cup you used to measure the water for the other bowl. For this bowl, you will need 1 cup of water. Go to the sink and fill the liquid measuring cup up to the 1 cup mark. -If you are having problems finding the 1 cup mark, it should be towards the top. Again, rest the liquid measuring cup on the counter, take a step back and check to see the level of the water. -Remember to look at the top of the “bubble”. It should be at the 1 cup mark if measured correctly. What To Do:
What To Do: Pour the 1 cup water into the second bowl along with the teaspoon of Borax. Mix the Borax and water together. -Again, you can use your hands or you can use a spoon if you would like. Make sure to mix the water and Borax together well. The Borax will need to be completely dissolved. Once again, have someonein your house take a picture with the disposable camera of you mixing everything together. You may need to mix for a couple of minutes to get the Borax completely dissolved in the water. Once mixed, set the bowl aside. Wash your hands with soap and warm water. Try to get off any remaining Borax from your hands.
Predict and Write: Predict what you think will happen when the two bowls are mixed together. Will they need to be mixed together? Will it be runny at first? Will it be stiff? ____________________________________________________________________________________________________________________________________________________________________ If for some reason your measurements were not correct, predict how this would effect the final slime product. _________________________________________________________________________________________________________________________ _______________________________________ __________________________________________________________________________________
Bring both bowls back to your working station. SLOWLY empty the first bowl (colored glue mixture) into the second Borax and water mixture bowl. Set the empty bowl aside to be washed. Very slowly, begin to mix the contents of bowl bowls together. -Again, use your hands or a spoon, whichever you prefer. What To Do:
The slime should immediately begin to form. Stir and mix it as much and as best as you can. You will need to dig in it and knead it (like bread). Continue this until the mixture gets less sticky. -Do not worry, this will be sticky and messy, but that is part of the fun! Do not worry about the extra water in the bowl. It will not be absorbed. When finished mixing your slime, simply pour out the excess water. What To Do:
What To Do: Once you are completely finished mixing together your slime and have dumped out all the extra water, you may take out your slime and play with it! Your finished! TA-DAH! You made your very own slime!
Wrapping it Up: For the third and final time, have someonein your house take a picture with the disposable camera of you. In this picture, you can be showing your slime or, if you want, it can be of you playing with your newly made slime. When you are finished playing with your slime, put it in a plastic bag and place it in the refrigerator. This will keep mold from growing on it. YUCK! Do not worry if, at any time, you got something on your clothing while making this slime. Everything is washable! Taken from: http://www.hometrainingtools.com/slime-recipes-project/a/1660/
To make your own slime, right in your very own kitchen, all you needed were 4 simple ingredients! The trick to successfully making slime though, is to measure those ingredients carefully. You need the exact amount of each, for the slime to turn out just right. Did your slime turn out? If so, you were able to measure the ingredients correctly! Give yourself a pat on the back! Measuring, especially measuring liquid amounts, like you just did to make slime is not an easy task. Congratulations on a job well done! Wrapping it Up:
Now that you are finished making your slime, please close up the Elmer’s White Glue, coloring food package, and the Borax and put them back into the box. Once you have put away the ingredients that helped make the slime, please wash the materials. Put the clean liquid measuring cup, ½ cup, teaspoon, and disposable camera back into the box. Finish the rest of this activity. Remember to be sure everything that came home in the box goes back into the box and returns to school after you finish the activity. Everyone in the class will be making their own slime, just like you, with these materials so we don’t want to loose them! Wrapping it Up:
