Dirt Bike Comparing Fractions is a multiplayer math game that allows students from anywhere in the world to play tug of war with each other while practicing comparing fractions! Students can compete against each other.

This is a fun activity where students get a bowl of Fruit Loops and then count them up and sort them by color.  Then they have to compare the numbers of each color with each other.

Comparing numbers using the Fruit Loops activity

Here is a website that has a sliding animation to demonstrate the size of cells and compares them to many other objects, including viruses, parts of cells, and bacteria.  This would be a great visual for your students when introducing the cell.

Students will compare the size of each pair of shapes. They will color each shape according to the comparison.

EarthScience.xyz is a website that teaches earth science to students.  It is a step-by-step book containing all the information needed to learn about the Earth.  Teachers can have access to all the labs and assignments that are taught at Snowflake High School.  There are tons of high-quality graphics, animation, and videos that will make presenting geology, meteorology, oceanography, paleontology, and astronomy to students engaging and fun.

In this Earth Science activity, students will gain a better understanding of what gases the atmosphere is made out of. Students will need to work some math problems out, converting percents and decimal places to determine ppm, parts per million. Students will gain an understanding that greenhouse gases make up such a small amount of the atmosphere, but are extremely important in keeping the temperature balance in check.

In this game, students will destroy aliens and space junk.  If they get an alien, they have to answer a context clues question.  If they miss, they lose a life.  How many aliens can they hit? If space junk hits the ship, students will be given a multiplication question to answer.

In this digital worksheet, students will practice and better gain an understanding of how to use context clues. Students will read a sentence and then define the bolded word. As an add-on, I also have students circle all of the verbs in the sentence. Because it is a Google Doc, the teacher can substitute their own students' names into the worksheet. This makes it more fun and engaging. The student's names are all italicized, and the words that require context clues are all bolded.

I do this convection currents demonstration when discussing how air moves. This can be used as well when discussing volcanoes, mantle convection, and water convection. You can find the worksheet for the air convection model at Teachers Pay Teachers.

In this Earth Science or Physical Science lab, students will gain an understanding of the three types of thermal energy transfer: conduction, radiation, and convection. Students will use hot, cold, and room temperature water to demonstrate convection by using food coloring. Students will then see how long chocolate chips take to melt when you add heat to just one side of some tin foil. Finally, they will use heat lamps, thermometers, and dark and light-colored papers to demonstrate radiation and the absorption of radiated heat.
