Learners explore using energy from the sun for heating and cooking as they build and compare the performance of four solar cooker designs. This excellent two-day lesson has groups of students build and test a variety of solar cookers....

Can you name all of the Mexican states? Most Americans can't, even though Mexico is our close neighbor. Encourage your Spanish learners to research a Mexican state and create a comprehensive PowerPoint to share the newly acquired...

Couches, carpets, and even computer keyboards now advertise they are spill-resistant, but what does that mean? Scholars use physical and chemical methods to coat surfaces with thin films to test their hydrophobic properties. Then they...

Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...

Students extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

Science can be quite tasty. A delectable unit from NASA shows learners why it's important to consider food, nutrition, and health in space. Four lessons explore the idea in great depth, including testing cookie recipes. Along the way,...

Mmmmmmm, here is a tasty little slide show to use when introducing upper-elementary learners to the sense of taste. Photographs and detailed computer images accompany explanatory text about how the taste buds and the nose send signals to...

Set youngsters in motion when studying forces. This quick animated film stars Sam and Mia, two intelligent but cool kids who talk about forces and motion on the soccer field. Consider using this resource when preparing junior-high...

Zoe needs to back up her music collection, but do her friends have enough space on their computers to help? Find out as you teach your class how to add two- and three-digit numbers with regrouping. Place value is emphasized as both the...

Learning how to regroup when subtracting numbers can be challenging and requires a solid understanding of place value. Walk your class through the steps with a clear and explicit presentation that addresses standard regrouping and...

Full of problems with polygons, angles, lines, and triangles, your learners get a multi-page packet that provides all they need to know. It contains many of the standard problem types as well as some more challenging questions. 

This is what all of the excitement has been building up to! Young engineers create engineering drawings, use machines to manufacture their products, test, and evaluate their designs in the last step in the engineering design...

Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Children enjoy playing with silly putty, but it provides more than just fun. Young scientists make their own silly putty using different recipes. After a bit of fun, they test and graph the viscosity of each.

The class works to identify solutions using the discriminant.They use part of the quadratic formula to find the number of solutions a quadratic equation will have. They calculate how-many times the quadratic function will cut the x-axis....

Students discover the properties of light (radiant) energy from the sun by experimenting with solar collectors, cookers, and calculators. After a lecture/demo, students create their own solar collectors and test their efficiency.

Students apply their knowledge of friction, drag, mass and gravity as they design, build, and test mini-bobsleds.

Kids love working with their peers. Get your class into small literature circles and have them complete weekly assignments. Before beginning this week's activity, have each learner write a letter from Esperanza in California to Abuelita...

What a wonderful way to explore wind power! Through this lesson, learners get a background in the history of wind power, create their own wind turbine, and the test their designs. This is a terrific way to tie scientific principles to...

We landed on the moon with less computing capabilities than you can find in this app! Here is a multiple function calculator that takes all the power you get from a handheld and adds the wonderful large screen that only a tablet can...

Fourth graders read a short story and then answer questions based on what they read. Learners are asked to support their answers with evidence from the text.

Statistically, practicing this packet completely helps young mathematicians do well on the test. The packet is adaptable to many grade levels as it includes basic probability and goes up to data analysis with mean, median, and...
