Good Morning Here’s Your Video!
STEM LESSON ABOUT ELEPHANT TOOTHPASTE
What is a Chemical Change?
Begin a discussion by asking the children a few questions to get them thinking. Have you ever made a cake? How does a cake look different before and after you cook it? Have you ever mixed foods together and seen them bubble? What do you think a chemical is?
Have you ever baked a cake? To make a cake you add things like sugar, flower, and eggs together to make something different, a cake. Can you take your cake and try and get just the sugar out of it? No, because the cake is not the same as the ingredients you used to make it. This is an example of a chemical change. During a chemical change, the original ingredients or substances are changed into a new substance. A few things that you can notice when you see a chemical change can include change in heat and smell, appearance of bubbling, and a color change.
The foam made in this classic Elephant’s Toothpaste reaction is extra-special because it goes through a chemical change. Hydrogen peroxide is used on cuts and is made of water and oxygen gas. Yeast is alive and used in bread to help it fluff up and rise in the oven. Yeast can be used as a catalyst, speeding up the release of oxygen. This means that if you mix yeast with hydrogen peroxide, the hydrogen peroxide will quickly break down into water and oxygen gas. The oxygen gas forms bubbles. These bubbles would usually escape from the liquid and pop quickly but adding a little dish soap traps the bubbles and creates lots of foam. This foam looks like a giant squeeze of toothpaste—almost big enough for an elephant, but don’t get the foam in your mouth because it will make you sick.

Our sound for this week is y. Can you think of words that begin with y? Yes, yarn and yellow are a few. If you or your parent trace and cut out a y letter you could glue yarn on it or guess what color you could color it? I cut out a y and other pieces of paper to make a yak. It’s not hard to do. You will see it in a picture I’m sending.
If you don’t know what a yak is here is a bit of information about them. Yaks are related to cattle. There are two types, wild and domesticated. Yaks live in icy, cold mountainous regions of Central Asia. You can find it on a world map. Yaks are large animals that have strong sturdy legs and thick long shaggy fur that keeps them warm in the bitter cold. They eat grasses, herbs and small shrubs. They crunch on ice or snow for water. You can find a lot of pictures and information about them online. Your family can help you with that.
Here’s another fun project for the letter Yy:
For math this week I thought doing some work on before, between and after numbers would be fun to practice. What numbers you use will depend on your child’s number sense. I have sent an example for you to see. Parents, you can make the pages and your child can tell you and then write the number that fits the space. If your child doesn’t write numbers yet you can use a highlighter to write and they can trace. See if they can give you the answer first. Use more challenging numbers for those who are able. Counting and number tracing or writing is always helpful. If you have any questions please email me. I like hearing from you. Thank you for the April and May pages I’ve been receiving. I’ll be putting the books together at the beginning of June so there is still time.
Have a wonderful week!
Love, Mrs. White
