Mixture Basics

Mixture Basics

Simple Mixture Activity

Cut an apple into 6 sections, quarter some oranges, quarter a pear, etc. Put in large bowl to make a fruit salad 'mixture'. Grapes cut in half also work well. The individual components can then be put back together using physical forces. The class can then eat the [[#|demo]] for a healthy snack!

Note: It's best not to cut the fruits into very small bits!

Simple Solution Demo

Mix lots of salt and water and heat it to get everything to go into solution. Then drip the salt water on black paper and the kids can watch the salt re-appear.

Separating a Solution Activity

Students can separate the colored solution in different markers. Take a coffee filter and make a hole in the middle. Give students water-soluble markers or vis-a-vis [[#|pens]], and have them draw simple designs on the filter. This is especially effective with black or blown markers. Roll a second filter into a cylindrical 'wick', and stuff this through the hole in the first filter. Rest the filter on a beaker, with the wick in water in the beaker. The [[#|black ink]] will separate into multiple colors.

Separating a Solution Demo

Mark a stick of white chalk with black marker. Stand chalk in a beaker holding about 1" of isopropyl alcohol (can be purchased in drug store). If using a 250 mL beaker fill it up with isopropyl alcohol until the 75 mL line. The alcohol will move up the chalk and separate the ink into individual colors. This takes about 20 minutes.

Density Demonstration


Discuss density and show the students 2 cans of soda. One is regular, the other is [[#|diet]]. Ask them if they think the cans have the same density. Then ask if they think they will sink or float. Then [[#|demo]] the sinking of the regular can (because of the [[#|sugar]]) and the floating of [[#|the diet]] can. Discuss why one floats and why the other sinks.

Density Activity

Create sinking/floating kits to hand out. Each student receives a small bowl/Tupperware full of small objects (screw, paperclip, string, cork, weigh boat, etc…). After you give the lesson, they can go through their materials and try to guess which ones will sink or float. Fill each of their bowls with water, and they can test each object and record their data. You can wrap it up with a discussion of the results.

Water Cycle Demonstration

You can just do a quick [[#|demo]] of the water cycle by putting some dirt in a cup, pouring warm water on the dirt, covering it with saran wrap, and putting it in the sun so you can watch the condensation form.

Total Cereal Demonstration
You can do a [[#|demo]] with a box of Total Cereal, hot water, a blender (or potato masher) and a magnet. Grind up the cereal in water and let it get soggy. Once it’s soggy and pureed, swirl the magnet around in the cereal slop and you’ll be able to pull out a TON of iron shavings. It’s pretty cool. The other demo you can do is to grind up french-fries in water and allow the [[#|fat]] and water layers to separate. If you’re really ambitious you can measure the amount of fat in one container of french-fries or compare different types of foods for their ‘fattiness’.
