What on Earth are we walking on?

FOCUS QUESTION*

What makes up the ground we walk on?

 

PREDICTION/ HYPOTHESIS*

The ground we walk on is made up of dirt. I think that this is true because that is what I see under my grass.  

Predictions of what the dirt will look like: wet, clumpy, brown, grass in it, worms

 

PLANNING  

1. Every group will receive plate, bag of dirt, and pictures.
2. The group will use their senses to make predictions about what the ground is made of
3. The group will make observations using a data chart about how it looks, feels, smells, and what they hear 
4. The teacher will make a group chart on the smart board.
5. The class will draw their conclusions about what they have learned 

 

 DATA*

recorded color, taste, smell, sound and feel of the dirt sample

Color- brown, red

taste- DID NOT EAT

sound- sounds "gritty" when you shake it on the plate

feel- feels wet, soft, grainy

 

CLAIMS AND EVIDENCE*

We saw different parts of the soil using our 4 senses. We discovered that our ground isn't just made up of dirt. When  we compared what we thought to what we found out, we noticed that dirt is made up of things like rocks, weeds, grass, sticks etc. 

 

CONCLUSION/REFLECTION*

We discovered there are many different things that make up the ground and we can see this by using our senses.

 

**QUESTIONS:   How many different things make up the ground?
