"This lesson will introduce DNA, genes, chromosomes, the chemicals that make up
DNA, etc. After the basic information, students will do an experiment in which
they will separate out DNA from peas. Knowing that DNA can be separated will
give them a base of understanding for future lessons in biology, evolution,
biotechnology, and health technology."
"This lesson will encourage students to examine the trade-offs involved in our
use of energy, a topic they will likely revisit throughout their lives.
This lesson is built around an interactive called
Power Up!
in
which students choose how to power a city. They will have to choose between
various energy sources, taking into account the trade-offs between cost and the
environmental impact of each choice. Discussions before and after the game will
examine the various options and what students may want to take into account when
making their decisions."
What is it like to work as a paleontologist? In Activity 1, students listen to or read an interview with paleontologist Paul Sereno, a National Geographic Explorer-in-Residence, to learn about his passion for science and his discovery of SuperCroc in sub-Saharan Africa. In Activity 2, students join a dig with paleontologist Mike Everhart to learn what happens when a scientist in the field suddenly discovers fossil remains. In the Closing Activity, students create a story or conduct an interview and present or record their work for an imaginary radio program.
"This lesson uses the four modalities of reading (reading, writing, listening,
and speaking) on a math word problem to bridge the gap between reading and math.
After a read-aloud from the book Math Curse by Jon Scieszka and Lane
Smith, students create their own word problems with answers. Students solve each
other's problems. As they reread the word problems, fluency and comprehension
increase. Finally, students use the skills they've learned creating word
problems to complete a crossword puzzle. As students read the math concept words
presented in the
puzzle and write the correct answers, their reading and
writing math vocabulary skills increase."
"To engage students in making design decisions that affect the transfer of energy
between a building and the outside environment. To help students identify and
consider the types of decisions involved in improving a building's energy
profile. To analyze the green roof option in economic and community terms."
Thinking about numbers using frames of 5 can be a helpful way to learn basic number facts. The four games that can be played with this applet help to develop counting and addition skills.
Instructions
Choose one of the four games that can be played with this applet:
How Many: Identify how many items or empty squares there are.
Build: Drag a certain number of items to the frame.
Fill: Determine how many items are needed to fill the remaining squares.
Add: Drag items to complete addition problems.
Choosing Play All from the Games menu will randomize which of the four games is played.
