Simple Machines

Overview: Students will build upon their skills in explaining and understanding how simple machines work. Incorporated into these skills will be activities investigating pulleys, inclined planes, and wheel and axle. These activities will explore the following concepts: • Understand how each of these simple machines work. • Understand the mechanical advantage and efficiency of a machine.

Learning About Heat

The teacher will provide students with a variety of activities focusing on heat, heat transfer, molecular motion, and reflection/absorption of solar radiation.

Using Scientific Inquiry and Technology to Understand Gravity

Students will build upon their skills in graphing, scientific inquiry, and measurement. Incorporated into these skills will be activities investigating Gravitational Interactions. These activities will explore the following concepts:

1. Gravity is a non-contact force acting upon an object which can be described in terms of magnitude and direction, and can be measured by weight.
2. Graph data can be explained through an energy diagram.
3. Every object exerts a gravitational force on every other object.

Background information for constructing a graph: Purpose – a graph shows relationships between two variables. With this activity the focus is on making a graph using the acronym TAILS. The acronym is intended to help guide students in constructing graphs. “T” stand for title, “A” for axes, “I” for intervals, “L” for labels, and “S” for spacing. Both the “x” and “y” axes need to be present and in the positive direction. The “x” axis is known as the independent variable while the “y” axis is known as the dependent variable. All intervals need to be at equal lengths in the spacing along the axes. The axes intervals must have enough room to easily have the minimum and maximum values. Labels must be placed on both axes with the variable itself and the units used to measure them.

What's for Lunch? (lesson 2 of 3)

Students will gain understanding with the relationships between food chains and food webs. Students will be able to distinguish the roles of predator and prey.

What's for Lunch? ( 1 of 3 lessons)

Students will compare and contrast hervivores, carnivores, omnivores, and decomposers.

Blood Unit

The unit on blood gives students the ability to understand the different types of blood and how they play a role in transfusions. This unit also helps the students to understand the process used by lab technicians when it comes to finding illnesses.

Scaffolding the Scientific Method: A comprehensive unit

Take students through the scientific method step-by-step in this ample unit. Each lesson teaches a new step in the process and uses a simple, yet entertaining experiment to provide students with motivating practice.

Who''s Got the Crunch

Working in small groups, students will identify the problem, observe, hypothesize, write a procedure, and draw a conclusion, while tasting 3 types of cereals.

Hypothetically Speaking...Incorporating Scientific Inquiry

This bulletin board idea generates lots of scientific experiments in the classroom and helps you make sure you are discussing each element of scientific inquiry.

What''s Nectar?

Fun hands-on lesson for spring that shows how butterflies get nectar from flowers. Lesson begins with plants and flowers and leads to a lesson about butterflies.
