Students fill a cart with books. The cart has a handle on each end.

Which actions will make moving the cart in one direction easiest for the students?

Draw arrows showing the direction each student should move. 3.6(B)

Multiple Choice

Students investigate the physical properties of some substances. They draw a table to show how the substances can be grouped. The students need to complete the table with column headings.

Which column headings should the students use for their table? 5.5(A)

​Mixtures

​A mixture is a combination of two or more different substances that do not lose their identifying characteristics when combined. Can be easily separated.

Open Ended

The table lists the ingredients of five different mixtures.

In which mixtures do all the ingredients maintain their physical state?

Write the Mixture(s) number.

Fill in the Blank

What does the picture demonstrate about light?

Light that goes through water ____ and ____ travel in a straight line.

Word Bank: Reflects, refracts, can, cannot

Poll

How deltas are formed?

• When flowing water slows and deposits sediment.

• When glaciers slowly move across the landscape

• When winds pick up and move sediment away from the landscape

• When flowing water carves out the sides of a canyon

Multiple Choice

Lacewings are insects that hatch from eggs.

Which of these correctly compares the lacewing life cycle with the frog life cycle?

3.10(B) 5.2(D)

• Adult lacewings lay eggs, but adult frogs give birth to live larvae

• When they hatch, young lacewings and young frogs look different from their adult forms.

• When they hatch, both lacewings and frogs have long legs for jumping.

• Both adult lacewings and adult frogs have more legs than they had as larvae.

​Ecosystems have lots of different living organisms that interact with each other. The living organisms in an ecosystem can be divided into three categories: producers, consumers and decomposers.

Lets identify the role of each organism in this food web. ​

Draw

A partial forest food web is shown.

Circle only animals that receive energy transferred directly from consumers in this food web..

Physical Properties of Matter​

1. ​color​

2. electrical conductivity

   Conductors- allows electricity to pass through easily

   Insulator- ​does not allow electricity to flow through easily

3. thermal conductivity

   ​Condu​ctors- metals are good conductors, they conduct heat easily.

   Insulators- ​wood and plastic are good insulators, does not allow the heat to flow through easily.

4. response to magnetic forces- is attracted to magnets

5. solubility- it dissolves in water
