Day 61: Properties of Solids

Observing solids

Solid	Color	Texture	Hard or soft
Wooden block	Tan	Smooth	Hard
Cotton ball	White	Fluffy	Soft
Sandpaper	Brown	Rough	Hard
Sponge	Yellow	Bumpy	Soft

Which solid in the table has a rough texture?
Answer: _________________________________________________
Name the two solids in the table that are soft.
Answer: _________________________________________________
Choose one solid from the table. Explain how you could test whether it keeps its own shape.
Answer: _________________________________________________

Day 62: Properties of Liquids

Observing liquids

Liquid	Color	Clear or cloudy	Thick or thin
Water	No color	Clear	Thin
Honey	Gold	Clear	Thick
Milk	White	Cloudy	Thin
Pancake syrup	Brown	Clear	Thick

Which liquid in the table is cloudy?
Answer: _________________________________________________
Which two liquids are thick?
Answer: _________________________________________________

Day 63: A Fair Test: Which Liquid Flows Fastest?

Sample results

Liquid	Seconds to finish
Water	2
Cooking oil	5
Syrup	16

In the sample results, which liquid flowed fastest?
Answer: _________________________________________________
How many more seconds did the syrup take than the water?
Answer: _________________________________________________
Use the sample results to explain how thickness affects how fast a liquid flows.
Answer: _________________________________________________
_____________________________________________

Hands-on task: Race liquids down a ramp

Make a ramp: lean a clean baking sheet on two books so it is tilted. Use the same ramp for every liquid.
Draw a start line and a finish line on the sheet with tape. Keep the distance the same for every liquid.
Measure 1 spoonful of water. Pour it at the start line and count the seconds until it reaches the finish line.
Wipe the ramp. Repeat with 1 spoonful of cooking oil, then 1 spoonful of syrup.
Record your times in the table below.

Liquid	Seconds to finish
Water	____
Cooking oil	____
Syrup	____

The fastest liquid was:

Day 64: Sort Materials by Their Properties

Sample sorting chart

Item	What we observed	Group
Button	Round, keeps its shape	Solid
Juice	Flows when tipped	Liquid
Crayon	Waxy, keeps its shape	Solid
Shampoo	Thick, flows slowly	Liquid

Which items in the sample chart are liquids?
Answer: _________________________________________________
What did the scientist observe about the button?
Answer: _________________________________________________
Shampoo comes in a hard plastic bottle. Explain why the shampoo is sorted as a liquid even though the bottle is a solid.
Answer: _________________________________________________

Hands-on task: Sort a mystery bag

Ask an adult to fill a bag with six safe items, some solids and some liquids in closed containers, such as a spoon, a button, a crayon, a bottle of water, a bottle of shampoo and a cup of juice with a lid.
Take out one item at a time. Observe its color and texture, and whether it keeps its own shape or flows.
Gently tip each closed container to see whether the inside flows.
Sort the items into a solid group and a liquid group.
Record your observations in the table below.

Item	Color	Texture or flow	Solid or liquid
__________	____	__________	____
__________	____	__________	____
__________	____	__________	____
__________	____	__________	____
__________	____	__________	____
__________	____	__________	____

One property that helped me sort was:

Day 65: Independent Check: Solids and Liquids

A second liquid race

Liquid	Seconds to finish
Dish soap	9
Water	2
Ketchup	30

Answer on your own. An adult may read the questions aloud but should not give the answers.

Which liquid in the race was slowest?
Answer: _________________________________________________
Name one property you can use to describe a solid.
Answer: _________________________________________________
Sam says the race was fair even though he used a steeper ramp for the ketchup. Explain why he is wrong.
