Mixing Soil and Water

Mixing Soil and Water Worksheet: Mass is conserved in a mixture (Grade 4 Science, TEKS 4.6C)

Students weigh soil and water, mix them in a jar, and compare the sum of the parts with the scale, then see that the mass stays the same after the soil settles and in a salt water mixture. The page teaches the idea first, so no prior lesson is needed, and every answer is on the page.

What's Inside

• A teach box that defines matter, mass, and a mixture, with a worked sand and pebbles example
• Part A: jars on scales showing soil plus water and the mixture, with add, read, and circle questions
• Part B: a table of a salt water mixture and a sand and water mixture
• A raccoon guide with a hint that matches the answer key
• An answer key with answers marked in red, plus a short teacher note with what to watch for

How Teachers Use It

Read the teach box and the worked example together, then let students try Part A and Part B. It takes 8 to 10 minutes and prints clearly in black and white. The focus skill is showing that matter is conserved when a mixture is formed, part of TEKS 4.6C: demonstrate that matter is conserved when mixtures such as soil and water or oil and water are formed.

Why It Works

Clear jar and scale pictures make the idea easy to see: add the parts, read the scale, and the numbers match. Questions are short, mostly circle or one line answers, and the reasoning is on the teacher key. Pair it with the other Grade 4 mixing sheet to cover both soil and water and oil and water.
