Plants Lesson 2

Teaching Point: Good engineers can apply their knowledge of plants to plan and create a talking poster.

Resources: Simple Machines Song

Reflection Question: Watch video on Engineering site. Complete worksheet.

Plants Lesson 1

Teaching Point: Good engineers can ask questions about plant parts, needs, and life cycle to understand how plants grow and meet their needs.

Resources: Needs of a Plant, Parts of a Plant, How Does a Seed Become a Plant?

Reflection Question: Sketch, label, AND color what your poster might look like. Make sure to include:

1. what plants need,

2. the parts of a plant (root, stem, leaves, flowers), AND

3. the plant life cycle (seed, germination, roots and stem, young plant, mature plant).

Make sure to put an X where you are going to put metal to connect the Makey Makey.

**Bring an empty cereal box.

To Get to the Other Side Lesson 3

Teaching Point: Good engineers can explain how the structure of a bridge affects its strength and how we can use different materials in our bridge designs.

Resources: Materials for bridges chart (below)

Vocabulary: beam bridge, deep beam bridge, arch bridge, balanced forces

Reflection Question: How does the structure of a bridge affect its strength? How can we use different materials in our bridge designs? (The strongest bridge we tested was ___________. This type of bridge is strong because _______. We can use the material ______ in our bridge by ________.)

To Get to the Other Side Lesson 2

Teaching Point: Good engineers can explain how balanced and unbalanced forces can affect the stability of a structure.

Resources: Balanced and Unbalanced Forces, class activity (see below)

Vocabulary: forces, structure, civil engineer, stable, unstable

Reflection Question: How do balanced and unbalanced forces affect the stability of a structure? Challenge: Give examples from class. (When forces are balanced, the structure is __________. When forces are unbalanced, the structure is __________. For example, I know if a structure is stable if _________________. For example, I know if a structure is unstable if _________________.)

Sticky Situation Lesson 4

Teaching Point: Good engineers can use the Engineering Design Process to design a strong wall using rocks and mortar.

• How have we used the Engineering Design Process?
  • Last class, we used the ask step by... Today, we used the imagine step by... We used the plan step by... We used the create step by...

Sticky Situation Lesson 3

Teaching Point: Good engineers can explain which materials are best for creating mortar by describing the materials' properties.

• Which properties of the materials (soil, sand, clay) made good mortar? Why?

Sticky Situation Lesson 2

Teaching Point: Good engineers can explain what makes a material a good choice for different purposes by talking about the properties.

• What is a materials engineer? Were you a materials engineer today?
  • A materials engineer is a person who studies _______ of materials to improve or create new _____________.

Sticky Situation Lesson 1

Teaching Point: Good engineers can compare types of walls by thinking about the materials.
