## Daily Math Activities

## 7.G.1 Solve problems involving scale drawings of geometric figures

including computing actual lengths and areas from a scale drawing

and reproducing a scale drawing at a different scale.

7.G.6 Solve real-world and mathematical problems involving area,

volume and surface area of two and three-dimensional objects

composed of triangles, quadrilaterals, polygons, cubes, and right prisms.

MP.2 Reason abstractly and quantitatively.

MP.4 Model with mathematics.

1. Review surface area and volume.

2. Use the unit cubes to model various shapes with different parameters.

For each shape, identify the surface area and volume.

Then, calculate the surface area to volume ratio.

3. Identify the meaning of surface area to volume ratio.

When would a large ratio be advantageous?

When would a small ratio be preferred?

4. Challenge! Design two boxes.

One must use the least cardboard possible but be able to hold a given volume.

One must offer the most surface area possible to cover with artwork, but still only

take up a given amount of space.

5. Share our designs. What was successful? What was the strategy?

Homework: Complete the volume problems.

1. Check the volume homework.

2. Design an new Pringles Can.

Determine the cost comparison and decide on a better design.

3. Serving sizes. How many ways can you find to cut a cake into equal servings?

1. Surface Area Shapes Challenge:

- Students are given a sheet of graph paper.
- They must use exactly 200 squared cm to create a pattern or a picture
- The pattern or picture must be taped/glued onto another piece of paper.
- Indicate the measurements of the sides of your shapes and a formula that could be used to find the area of that part of the pattern or shape.
- Show your work that indicates what numbers you added together to get exactly 200 square cm.

1. Define tessellation. What makes a tessellation?

2. Given the dot matrix, practice making some tessellations.

3. Decide on a pattern that you like best and create your tessellation.

1. Travelling Math

Figure miles/gal.

price / gal

Miles/price etc.

2. Compare driving different vehicles different distances.

3. What is the percent change?.

## Daily Science Class Activities

## Focus: - Matter is transferred continuously between one organism to

another and between organisms and their physical environments.

- In any particular biome, the number, growth and survival of

organisms and populations depend on biotic and abiotic factors.

**Monday, May 2, 2016**

1. Turn in the worksheet: Biogeography and Group C Turn in Science News.

2. Discuss the biotic and abiotic factors that determine if animals can live in a particular biome.

3. Can these factors change over time? Can they change by season?

4. Recall the Mono Lake Ecosystem.

What biotic and abiotic factors determined the populations found there?

5. Use population data to explain the changes that occur throughout the seasons at Mono Lake.

Complete the

*Analysis of Mono Lake Data*activity.

HOMEWORK: Finish the Analysis of Mono Lake Data.

---------------------------------------------------------------------------------------------------------------------------------------------

**Tuesday, May 3, 2016**

1. Check

*Analysis of Mono Lake Data*. Be sure to support your answers with evidence from graphs!

2. Mono Lake data provided us with evidence of population change from one season to another.

What might cause more permanent population changes?

3. Watch the video:

*Where Have All the Animals Gone?*and answer the questions as you go.

HOMEWORK: Check your answers to Where Have All the Animals Gone? to be sure that you have

answered all parts of the questions.

Group D: Science News is due on Friday.

--------------------------------------------------------------------------------------------------------------------------------------------

**Wednesday, May 4, 2016**

1. Discuss Where Have All the Animals Gone?

2. Recall our discussion of populations depending on biotic and abiotic factors.

(biogeography............ mono lake data............... endangered species...)

3. Watch the Brain Pop on Extinction.

4. Limiting Factors: Read pages 22-24 in the green resource book.

Define the seven terms found there about limiting factors.

HOMEWORK: Group D: Science News is due on Friday.

--------------------------------------------------------------------------------------------------------------------------------------------

**Thursday, May 5, 2016**

1. Review limiting factors from Tuesday.

2. Read about Wildlife Crisis in the special Earth Day edition of Science World.

3. Complete the extension activities.
