Throughout the day have students measure the water level.
Have students place the cups in a sunny spot outside. solids, liquids, and Gases have mass explained by the. Then have them record the height of the water level with a ruler. Explain with the Help Simple Experiments that Each State of Matter Has Mass. The strong laser flashes that hit the foil-like material sample briefly heated it up to 6000 degrees Celsius and thus generated a shock wave that compressed the matter to millions of times the atmospheric pressure for a few nanoseconds. Make sure they label the cup with their group name. In the experiment, a thin sheet of simple PET plastic was shot with a laser. Evaporating into Thin Airĭivide students into small groups and have them pour a cup of water. Which method was best? Have groups discuss and share their observations and findings with the class. To model solids, have students make a shape and link arms together. Have students time how long each method takes. Have your whole class model the particles that make up solids, liquids, and gases. They may want to put the ice cubes in a sunny spot, warm them up in their hands, or just put them in a cup on their desks. Remind your students that heat can change matter and adding more heat might make matter change faster.
Divide the students into small groups or pairs and have them find the fastest way to melt an ice cube. Ice Cube Meltdownīring in a bag of ice for your students. They should observe that they have much more room than before and are able to spread out freely. To model gases, have students dance about the room without touching each other. They can dance and observe that they have more space to move. To model liquids, students can place their hands on each other shoulders and walk slowly around the room. They can dance in place but keep the whole shape.
Have your whole class model the particles that make up solids, liquids, and gases. While this demonstration shows a physical change, remind students that acids and enzymes help to further break down food which is a chemical change.These classroom activities are designed to complement the Changing States of Matter topic on BrainPOP Jr. Students should observe that the food in the bag that has muscle contractions will break down more than the other bag. Put the bags down, have students make observations, wait another five minutes and repeat. Often, this is a classroom demonstration, so I will call students up to squeeze the bag to resemble stomach muscles. Tackling one experiment at a time, we worked our way through eight projects: > Rainbow Jar > Water Cycle in a Bag > Yeast Balloons > Ice Excavation > Mystery Balloons > Butter in a Jar > Balloon Balance > Ice Cream in a Bag We learned about different densities of particles by pouring a rainbow in a jar. Allow the bags to remain as they are.Īfter 5 minutes, mimic the stomach muscles moving to break down the food. For example, this experiment will mimic how the muscles of our bodies help to break down food in the human body to be digested.įill the same types of food inside each bag trying to keep them as similar as possible. We did a little experiment mixing baking soda (solid) with orange juice (liquid) to create bubbles (gas) You could also do the classic volcano experiment with. Reinforce the concept that science happens in our bodies, including physical and chemical changes.
