### Science Hands-On Activities!!

Here are some pictures from our 5th grade Science Grade Level meeting last week. We learned several fun activities that I know my students will LOVE! Cootie catchers, pipe cleaner art, vocabulary in pictures, bioglyphs, food chains, food, food, and did I mention FOOD! :)

### Layers of the Earth's Crust with CANDY!!!!!

We all can be bribed to pay attention with CANDY!!!! Or at least I can! I attended a science grade level meeting yesterday and I just LOVE our consultant!! She always does hands-on activities with us that we can bring back to the classroom and she always finds a way to incorporate food.

I had just started the layers of the Earth with my students this week. Our consultant gave us an activity with Peanut M&M candies to use with this lesson.  Be sure to check on peanut allergies before doing this lesson. The students carefully bit the peanut M&M candy in half. The outer chocolate shell represents the crust, the inner milk chocolate represents the mantle, and the peanut represents the core. Cute way to remember the layers!

### Subtracting with Magic 9 and Top & Bottom Division

We discussed some teaching strategies on numbers and operations at our grade level meeting today.

In sharing, we discussed the Magic 9 subtraction method. I don't know how it works, but it does every time if you follow the steps correctly. Once the kids get the hang of it, they just go with it.  I hope you can read the steps from the picture I posted. If not, someone please let me know and I will do another post with the steps for you.

Our consultant shared a new division technique with us that I call the Top & Bottom Method. Have the students list the numbers 0-9 and draw a line under it. Then they list the multiples of the divisor. They can use skip counting or repeated addition if they have trouble listing multiples from memory (or if it is a large divisor).
This lesson also incorporates function tables, estimation, factors, multiples, AND division!!

### The digestive tract: A science and math connection

Thursday of last week we did a math/science activity using a variety of objectives. We have been studying the different body systems in science this nine weeks. A fellow teacher told me about measuring the length of the digestive tract, so I googled it and found the lesson to use. On www.science-class.net, I found The Digestive Tract lesson plan I used.

I asked the students how far it was from my mouth to my stomach. Using a meter stick they measured the length from my mouth to my stomach. Then we discussed all the parts of your body the food passes through. They decided it was longer than what they measured on me if it had to go through all those places...

Each pair of students got a part of the digestive tract to make the length with yarn. A student estimated using the measurements from the lesson plan page to get an estimation of the length of the digestive tract. After each group measured and cut their yarn, they actually measured it. Then the students tied each part together, stretched it out, and measured the whole length. They found their estimate was pretty close. One student said the yarn was stretchy, so the measurement couldn't be exact.  (Good Thinking!)

I shared this lesson with a few other teachers and showed them our looonnnnggg digestive tract we made with yarn. They were amazed at how long it actually is!
